How do I use tooltip string in app designer

I want to have help text when the cursor hovers over buttons created in app designer.

With uicontrol in a figure I can do this with: uicontrol('Style', 'Pushbutton', 'String', 'Hello','ToolTipString','This is the tooltip string')

but how do you do this within app designer?

Answer 1

There is currently no way to add tooltips in App Designer. This is known to the developers and they are working to add this to a future release of MATLAB.

[Claire Motion]

Is this likely to be implemented in 2018a? As 2017b doesn't seem to have this yet, and it would be really good if it could be added!

[Alvaro Aguilar]

Is there an update to when tooltips will be added to MATLAB App Designer?

R2018b supports tooltips. See more below

2018b supports Tooltips.

2018b release notes

Enjoy!

"Tooltips: Create custom tooltips for UI components in apps Set the Tooltip property on a UI component to display a tooltip when the user hovers the mouse over the component at run time. Tooltips display even when the components are disabled.

The Tooltip property is available for UI components in App Designer apps and in figures created with the uifigure function.

If you are creating an app using GUIDE or the figure function, use the Tooltip property instead of the TooltipString property on UIControl, Table, Tab, PushTool, and ToggleTool UI components. For details, see TooltipString property is not recommended."

In 18b App Designer, you can use the Property Inspector from code or design view to add tooltips to your components - the code will automatically be generated for you as for other property sets.

on your opening function for your guide try:

handles.pushbutton1.TooltipString=['This is the Tooltip string!', char(10), ... 'And a 2nd line also.']);

I tried this in appdesigner, but it doesnt work there:

app.buttonGetFile.TooltipString=['This is the Tooltip string!']

No public property TooltipString exists for class matlab.ui.control.Button.

Hi, I have installed the R2018b but still I am not able to add a tooltipstring to any element, button, listbox, etc

[Lothar]

I've installed R2018b and tooltip in App Designer works well. To use the App in R2018a fails cause of missing tooltip functionality. So I tried to remove the tooltip in App Designer, but this leads to an error message which prevents removal of the tooltip.

Anny suggestions on this ?

This is a known bug with removing tooltips. The only way around it is to delete and remake the object as far as I know.

The name of the property to create a component specific tooltip is Tooltip

app.buttonGetFile = uibutton;
app.buttonGetFile.Tooltip=['This is the Tooltip string!']
