ButtonGroup Properties

Control appearance and behavior of button group

The properties listed here are valid for button groups in GUIDE or in apps created with the figure function. If you are using App Designer or the uifigure function, see ButtonGroup Properties instead. For more information, see GUIDE Migration Strategies.

Button groups are containers for managing exclusive selection of radio buttons and toggle buttons. Properties control the appearance and behavior of a button group. Use dot notation to refer to a specific object and property.

f = figure;
b = uibuttongroup(f);
b.BackgroundColor = [.5 .5 .5];

Title

expand all

Title, specified as a character vector, string scalar, or categorical array. If you specify this property as a categorical array, MATLAB® displays only the first element in the array.

MATLAB does not interpret a vertical slash ('|') character as a line break, it displays as a vertical slash in the title.

If you want to specify a Unicode® character, pass the Unicode decimal code to the char function. For example, ['Multiples of ' char(960)] displays as Multiples of π.

Title location, specified as 'lefttop', 'centertop', 'righttop', 'leftbottom', 'centerbottom', or 'rightbottom'.

Color and Styling

expand all

Title color, specified as an RGB triplet, a hexadecimal color code, or one of the color options listed in the table.

RGB triplets and hexadecimal color codes are useful for specifying custom colors.

  • An RGB triplet is a three-element row vector whose elements specify the intensities of the red, green, and blue components of the color. The intensities must be in the range [0,1]; for example, [0.4 0.6 0.7].

  • A hexadecimal color code is a character vector or a string scalar that starts with a hash symbol (#) followed by three or six hexadecimal digits, which can range from 0 to F. The values are not case sensitive. Thus, the color codes '#FF8800', '#ff8800', '#F80', and '#f80' are equivalent.

Alternatively, you can specify some common colors by name. This table lists the named color options, the equivalent RGB triplets, and hexadecimal color codes.

Border type, specified as 'etchedin', 'none', 'etchedout', 'beveledin', 'beveledout', or 'line'.

  • For a 3-D appearance, use etched or beveled borders.

    Use the HighlightColor and ShadowColor properties to specify the color of 3-D borders.

  • For a simpler appearance, use a line border.

    Use the HighlightColor property to specify the line border color.

Border width, specified as a positive integer value. The unit of measurement is pixels. Etched and beveled borders wider than three pixels might not appear correctly at the corners.

Border highlight color, specified as an RGB triplet, a hexadecimal color code, or one of the color options listed in the table.

Note

The behavior of the Clipping property has changed. It no longer has any effect on ButtonGroup objects. Child objects are now clipped to the boundaries of their parent container regardless of the value of this property. This property might be removed in a future release.

Font

expand all

Font name, specified as a system supported font name or 'FixedWidth'. The default font depends on the specific operating system and locale.

To use a fixed-width font that looks good in any locale, specify 'FixedWidth'. The actual fixed-width font used depends on the FixedWidthFontName property of the root object. Changing the FixedWidthFontName property causes an immediate update of the display to use the new font.

Example: 'Arial'

Font size, specified as a positive number. The FontUnits property specifies the units. The default size is system-dependent.

Example: 12

Example: 12.5

Font weight, specified as a value from the following table.

  • 'normal' — Default weight as defined by the particular font

  • 'bold' — Thicker character outlines than normal

MATLAB uses the FontWeight property to select a font from those available on your system. Not all fonts have a bold font weight. Therefore, specifying a bold font weight still can result in the normal font weight.

Note

The 'light' and 'demi' font weight values have been removed in R2014b. If you specify either of these values, the result is a normal font weight.

Font angle, specified as 'normal' or 'italic'. MATLAB uses this property to select a font from those available on your system. Setting this property to 'italic' selects a slanted version of the font, if it is available on your system.

Note

The 'oblique' value has been removed. Use 'italic' instead.

Font units, specified as one of the values from this table.

Units ValueDescription
'points'Points. One point is 1/72nd of an inch.
'normalized'Normalized values for specifying the font size as a fraction of the height. When you resize a UI component, MATLAB scales the displayed font to maintain that fraction.
'inches'Inches.
'centimeters'Centimeters.
'pixels'

Pixels.

Starting in R2015b, distances in pixels are independent of your system resolution on Windows® and Macintosh systems:

  • On Windows systems, a pixel is 1/96th of an inch.

  • On Macintosh systems, a pixel is 1/72nd of an inch.

On Linux® systems, the size of a pixel is determined by your system resolution.

Interactivity

expand all

Button group visibility, specified as 'on' or 'off'. The Visible property determines whether the button group displays on the screen. If the Visible property is set to 'off', the entire button group is invisible, but you can still specify and access its properties.

Changing the size of an invisible container triggers the SizeChangedFcn callback when it becomes visible.

Note

Changing the Visible property of a container does not change the Visible property of its child components even though hiding the container prevents its children from displaying.

Context menu, specified as a ContextMenu object. Use this property to display a context menu when the user right-clicks on a UI component. Create the context menu using the uicontextmenu function.

Currently selected radio button or toggle button, specified as a UIControl object.

Use this property to determine the currently selected button within a button group. You can also use this property to set a default button selection. If you want no selection, then set this property to [].

The default value of the SelectedObject property is the first radio button or toggle button that you add to the button group.

Note

The SelectionChangedFcn callback does not execute when you set the SelectedObject property programmatically.

Note

The behavior of the Selected property changed in R2014b, and it is not recommended. It no longer has any effect on ButtonGroup objects. This property might be removed in a future release.

Note

The behavior of the SelectionHighlight property changed in R2014b, and it is not recommended. It no longer has any effect on ButtonGroup objects. This property might be removed in a future release.

Position

expand all

Location and size (including borders and title), specified as a four-element vector of the form [left bottom width height]. This table describes each element in the vector.

ElementDescription
leftDistance from the inner left edge of the parent container to the outer left edge of the button group
bottomDistance from the inner bottom edge of the parent container to the outer bottom edge of the button group
widthDistance between the right and left outer edges of the button group
heightDistance between the top and bottom outer edges of the button group

All measurements are in units specified by the Units property.

Note

The Position values are relative to the parent container’s drawable area. The drawable area is the area inside the borders of the container and does not include the area occupied by the title. If the parent container is a figure, then the drawable area also excludes the menu bar and tool bar.

Example: Modify One Value in the Position Vector

You can combine dot notation and array indexing when you want to change one value in the Position vector. For example, this code sets the width to 0.5:

b = uibuttongroup;
b.Position(3) = 0.5;
b.Position
ans =

      0   0   0.5000  1.0000

This property is read-only.

Location and size (excluding borders and title), returned as a four-element vector of the form [left bottom width height]. This table describes each element in the vector.

ValueDescription
leftDistance from the inner left edge of the parent container to the inner left edge of the button group.
bottomDistance from the inner bottom edge of the parent container to the inner bottom edge of the button group.
widthDistance between the inner edges of the button group's right and left borders.
heightDistance between the inner edges of the button group's top and bottom borders. This distance excludes the title, if it exists.

All measurements are in units specified by the Units property.

Note

These are some important points to consider when using the InnerPosition property:

  • InnerPosition values are affected by the presence of a title, font characteristics, BorderType, and BorderWidth.

  • InnerPosition values are relative to the parent container’s drawable area. The drawable area is the area inside the borders of the container and exclude the area occupied by the title. If the parent container is a figure, then the drawable area also excludes the menu bar and tool bar.

Location and size (including borders and title), specified as a four-element vector of the form [left bottom width height]. All measurements are in units specified by the Units property.

This property value is identical to the Position property value.

Units of measurement, specified one of the values from this table.

Units ValueDescription
'normalized'These units are normalized with respect to the parent container. The lower-left corner of the container maps to (0,0) and the upper-right corner maps to (1,1).
'pixels'

Pixels.

Starting in R2015b, distances in pixels are independent of your system resolution on Windows and Macintosh systems:

  • On Windows systems, a pixel is 1/96th of an inch.

  • On Macintosh systems, a pixel is 1/72nd of an inch.

On Linux systems, the size of a pixel is determined by your system resolution.

'inches'Inches.
'centimeters'Centimeters.
'points'Points. One point equals 1/72nd of an inch.
'characters'

These units are based on the default uicontrol font of the graphics root object:

  • Character width = width of the letter x.

  • Character height = distance between the baselines of two lines of text.

To access the default uicontrol font, use get(groot,'defaultuicontrolFontName') or set(groot,'defaultuicontrolFontName').

MATLAB measures all units from the lower left corner of the parent object.

If you change the value of the Units property, it is good practice to return it to its default value after completing your computation to avoid affecting other functions that assume the Units property is set to the default value.

The order in which you specify the Units and Position properties has these effects:

  • If you specify the Units property before the Position property, then MATLAB sets Position using the units you specified.

  • If you specify the Units property after the Position property, MATLAB sets the position using the default Units. Then, MATLAB converts the Position values to the equivalent values in the units you specified.

Callbacks

expand all

Note

The name of this property changed from SelectionChangeFcn to SelectionChangedFcn in R2014b.

Selection changed callback, specified as one of these values:

  • A function handle.

  • A cell array in which the first element is a function handle. Subsequent elements in the cell array are the arguments to pass to the callback function.

  • A character vector containing a valid MATLAB expression (not recommended). MATLAB evaluates this expression in the base workspace.

For more information about specifying a callback property value as a function handle, cell array, or character vector, see How to Specify Callback Property Values.

This callback function executes when the user selects a different button within the button group.

If you specify this property as a function handle (or cell array containing a function handle), MATLAB passes an object containing callback data as the second argument to the callback function. This object contains the properties described in this table. You can access these properties inside the callback function using dot notation.

Property

Description

OldValue

Previously selected button, or [] if none was selected

NewValue

Currently selected button

Source

The parent ButtonGroup object

EventName

'SelectionChanged'

Define a SelectionChangedFcn callback to make your program respond when the user selects different buttons within the button group. Do not code the response in the individual component callback functions.

If you want another component to respond to the selection, then that component's callback function can access the selected radio button or toggle button from the SelectedObject property of the ButtonGroup object.

Size change callback function, specified as one of these values:

  • A function handle.

  • A cell array in which the first element is a function handle. Subsequent elements in the cell array are the arguments to pass to the callback function.

  • A character vector containing a valid MATLAB expression (not recommended). MATLAB evaluates this expression in the base workspace.

Define this callback to customize the app layout when the size of this container changes (e.g., when the user resizes the window).

The SizeChangedFcn callback executes when:

  • This container becomes visible for the first time.

  • This container is visible while its size changes.

  • This container becomes visible for the first time after its size changes. This situation occurs when the size changes while the container is invisible, and then it becomes visible later.

Other important points to consider when defining a SizeChangedFcn callback:

  • Consider delaying the display of this container until after all the variables that the SizeChangedFcn uses are defined. This practice can prevent the SizeChangedFcn callback from returning an error. To delay the display of the container, set its Visible property to 'off'. Then, set the Visible property to 'on' after you define the variables that your SizeChangedFcn callback uses.

  • If your app contains nested containers, they resize from the inside out.

  • To access the container that is resizing from within the SizeChangedFcn, refer to the source object (the first input argument in the callback) or use the gcbo function.

Tip

As an easy alternative to specifying a SizeChangedFcn callback, you can set the Units property of all the objects you put inside a container to 'normalized'. Doing so makes those components scale proportionally with the container.

See Lay Out a UI Programmatically for more information about managing layouts with SizeChangedFcn callbacks.

Button-press callback function, specified as one of these values:

  • A function handle.

  • A cell array in which the first element is a function handle. Subsequent elements in the cell array are the arguments to pass to the callback function.

  • A character vector containing a valid MATLAB expression (not recommended). MATLAB evaluates this expression in the base workspace.

For more information about specifying a callback property value as a function handle, cell array, or character vector, see How to Specify Callback Property Values.

The ButtonDownFcn callback is a function that executes when the user clicks a mouse button within the container.

Component creation function, specified as one of these values:

  • A function handle.

  • A cell array in which the first element is a function handle. Subsequent elements in the cell array are the arguments to pass to the callback function.

  • A character vector containing a valid MATLAB expression (not recommended). MATLAB evaluates this expression in the base workspace.

For more information about specifying a callback property value as a function handle, cell array, or character vector, see How to Specify Callback Property Values.

This property specifies a callback function to execute when MATLAB creates the component. MATLAB initializes all component property values before executing the CreateFcn callback. If you do not specify the CreateFcn property, then MATLAB executes a default creation function.

Use the gcbo function in your CreateFcn code to get the component object that is being created.

Setting the CreateFcn property on an existing component object has no effect.

Component deletion function, specified as one of these values:

  • A function handle.

  • A cell array in which the first element is a function handle. Subsequent elements in the cell array are the arguments to pass to the callback function.

  • A character vector containing a valid MATLAB expression (not recommended). MATLAB evaluates this expression in the base workspace.

For more information about specifying a callback property value as a function handle, cell array, or character vector, see How to Specify Callback Property Values.

The DeleteFcn property specifies a callback function to execute when MATLAB deletes the component (for example, when the user closes the window). MATLAB executes the DeleteFcn callback before destroying the properties of the component object. If you do not specify the DeleteFcn property, then MATLAB executes a default deletion function.

Use the gcbo function in your DeleteFcn code to get the component object that is being deleted.

Resize callback function, specified as one of these values:

  • A function handle.

  • A cell array in which the first element is a function handle. Subsequent elements in the cell array are the arguments to pass to the callback function.

  • A character vector containing a valid MATLAB expression (not recommended). MATLAB evaluates this expression in the base workspace.

Note

Use of the ResizeFcn property is not recommended. It might be removed in a future release. Use SizeChangedFcn instead.

Data Types: function_handle | cell | char

Callback Execution Control

expand all

Callback interruption, specified as 'on' or 'off'. The Interruptible property determines if a running callback can be interrupted.

There are two callback states to consider:

  • The running callback is the currently executing callback.

  • The interrupting callback is a callback that tries to interrupt the running callback.

Whenever MATLAB invokes a callback, that callback attempts to interrupt the running callback (if one exists). The Interruptible property of the object owning the running callback determines if interruption is allowed:

  • A value of 'on' allows other callbacks to interrupt the object's callbacks. The interruption occurs at the next point where MATLAB processes the queue, such as when there is a drawnow, figure, getframe, waitfor, or pause.

    • If the running callback contains one of these commands, then MATLAB stops the execution of the callback at this point and executes the interrupting callback. MATLAB resumes executing the running callback when the interrupting callback completes.

    • If the running callback does not contain one of these commands, then MATLAB finishes executing the callback without interruption.

  • A value of 'off' blocks all interruption attempts. The BusyAction property of the object owning the interrupting callback determines if the interrupting callback is discarded or put into a queue.

Note

Callback interruption and execution behave differently in these situations:

  • If the interrupting callback is a DeleteFcn, CloseRequestFcn, or SizeChangedFcn callback, then the interruption occurs regardless of the Interruptible property value.

  • If the running callback is currently executing the waitfor function, then the interruption occurs regardless of the Interruptible property value.

  • Timer objects execute according to schedule regardless of the Interruptible property value.

  • MATLAB does not save the state of properties or the display when an interruption occurs. For example, the object returned by the gca or gcf command might change when another callback executes.

See Interrupt Callback Execution for an example that shows how the Interruptible and BusyAction properties affect the behavior of a program.

Callback queuing specified as 'queue' (default) or 'cancel'. The BusyAction property determines how MATLAB handles the execution of interrupting callbacks. There are two callback states to consider:

  • The running callback is the currently executing callback.

  • The interrupting callback is a callback that tries to interrupt the running callback.

The BusyAction property of the source of the interrupting callback determines how MATLAB handles its execution. The BusyAction property has these values:

  • 'queue' — Put the interrupting callback in a queue to be processed after the running callback finishes execution.

  • 'cancel' — Do not execute the interrupting callback.

Whenever MATLAB invokes a callback, that callback always attempts to interrupt an executing callback. The Interruptible property of the object whose callback is running determines if interruption is allowed. If Interruptible is set to:

  • on — Interruption occurs at the next point where MATLAB processes the queue. This is the default.

  • off — The BusyAction property (of the object owning the interrupting callback) determines if MATLAB enqueues or ignores the interrupting callback.

See Interrupt Callback Execution for an example that shows how the BusyAction and Interruptible properties affect the behavior of a program.

This property is read-only.

Deletion status, returned as 'off' or 'on'. MATLAB sets the BeingDeleted property to 'on' when the DeleteFcn callback begins execution. The BeingDeleted property remains set to 'on' until the component object no longer exists.

Check the value of the BeingDeleted property to verify that the object is not about to be deleted before querying or modifying it.

Ability to become current object, specified as 'on' or 'off':

  • 'on' — Sets the current object to the ButtonGroup when the user clicks the component in the running app. Both the CurrentObject property of the Figure and the gco function return the ButtonGroup as the current object.

  • 'off' — Sets the current object to be the closest ancestor of the ButtonGroup whose HitTest is 'on' when the user clicks the component in the running app.

Parent/Child

expand all

Parent object, specified as a Figure, Panel, ButtonGroup, or Tab object. Use this property to specify the parent container when creating a UI component or to move an existing UI component to a different parent container.

ButtonGroup children, returned as an empty GraphicsPlaceholder or a 1-D array of component objects. Although a button group manages only the selection of radio buttons and toggle buttons, its children can be instances of Axes, Panel, ButtonGroup, or any style of UIControl objects.

You cannot add or remove children using the Children property. Use this property to view the list of children or to reorder the children. The order of the children reflects the front-to-back order (stacking order) of the components on the screen. MATLAB might not allow you to change the order of certain objects. For example, UIControl and Legend objects are always in front of Axes objects.

To add a child to this list, set the Parent property of the child component to be the ButtonGroup object.

Objects with the HandleVisibility property set to 'off' do not list in the Children property.

Visibility of ButtonGroup handle, specified as 'on', 'callback', or 'off'.

This property controls the visibility of the ButtonGroup handle in its parent's list of children. When a handle is not visible in its parent's list of children, it is not returned by functions that obtain handles by searching the object hierarchy or querying handle properties. These functions include get, findobj, gca, gcf, gco, newplot, cla, clf, and close. The HandleVisibility property also controls the visibility of the object’s handle in the parent figure's CurrentObject property. Handles are still valid even if they are not visible. If you know an object's handle, you can set and get its properties, and pass it to any function that operates on handles.

HandleVisibility ValueDescription
'on'The ButtonGroup handle is always visible.
'callback'The ButtonGroup handle is visible from within callbacks or functions invoked by callbacks, but not from within functions invoked from the command line. This option blocks access to the ButtonGroup at the command-line, but allows callback functions to access it.
'off'The ButtonGroup handle is invisible at all times. This option is useful for preventing unintended changes to the UI by another function. Set the HandleVisibility to 'off' to temporarily hide the handle during the execution of that function.

Set the graphics root ShowHiddenHandles property to 'on' to make all handles visible, regardless of their HandleVisibility value. This setting has no effect on their HandleVisibility values.

Note

Do not try to access radio buttons and toggle buttons that are managed by a uibuttongroup outside of the button group. Set the HandleVisibility of those radio buttons and toggle buttons to 'off' to prevent accidental access.

Identifiers

expand all

This property is read-only.

Type of graphics object, returned as 'uibuttongroup'.

Object identifier, specified as a character vector or string scalar. You can specify a unique Tag value to serve as an identifier for an object. When you need access to the object elsewhere in your code, you can use the findobj function to search for the object based on the Tag value.

User data, specified as any array. Specifying UserData can be useful for sharing data within apps. See Share Data Among Callbacks for more information.
