How can i create multiple choice questions GUI using Guide ?

I need to create a GUI with Multiple Choice Questions

There will be 15 questions, four choices for each question,push button to submit the answer and there will be 15 stars. if the user selects a correct answer the star becomes green,if not star will turn to red.

I need to know which choice the user has selected ?

I attached an snapshot of how i did it.

I tried to insert the stars but it didn't seem to work.

Hope somebody can help me. Thanks in advance.

How can we add 15 questions in GUI ?

what about the star indications ? can you help me with that ?

I think that you would have a Next button to go from one question to the next. In the callback for this button, you would need to update the question and answers for that next question.

As for the star, you mentioned I tried to insert the stars but it didn't seem to work. What did you do? Do you have a green star image and a red one?

The best way to have 15 questions, if you don't want to take up your whole screen, is to use a popup control (a drop down list).

Alternatives would be a listbox control,

or calling the menu() function to popup a dialog box but that only lets them interact when you call the function, not whenever they want like a control.

Again, I recommend the popup control as the best option for letting the user choose from a list of 15 options.

Thanks for the answer Image Analyst.

Can we use the slider menu ?

[Image Analyst]

No. Making the user slide a slider (scrollbar) and then telling them what option they "are on" via a static text label would be a horrible, user-hostile way of letting a user pick from a set of options.

[Prashanth Damojipurapu]

Okay.

[Image Analyst]

If you want to let them pick from a continuum of values, then a scrollbar would be okay, like "How much do you like this product on a scale of 0 to 10?" But it would not be good for a discrete set of choices.

Prashanth - if your radio buttons have been created within a uipanel (which given your screenshot appears to be the case) then you can get the selected radio button from within the pushbutton callback as

 function pushbutton1_Callback(hObject, eventdata, handles)

 hSelectedRadioBtn = get(handles.uipanel1,'SelectedObject')

The above assumes that the Tag property for your panel has been set to uipanel1. Once you have the handle to the radio button, you can check its string to see what answer the user has selected.

Hello Prashanth,

Check the attached scripts..

Run the Test.m file and see the results..

Go through the logic added into callback of functions...Let me know if you dont get the logic..

[Prashanth Damojipurapu]

Thanks for the help.

I ran the file. Idea of question changing color was amazing.

I am still trying figure out the code.

[Prashanth Damojipurapu]

Can we use a draw function and Draw Star like figures and indicate them with color red or green ?

[Shameer Parmar]

Prashant,

Thanks for the response..

Actually, As per my knowledge till I have, we can not add star, because there is no star button. But We can put the square box instead of star.

How to do it :

1. Simply select the static textbox (which is square like structure always) and put just beside the question statement.

2. The default text of static textbox should be removed and make it blank. and change the back ground color as same of the back ground color of your GUI. (In this way it will always look like hidden box)

3. Now you need to apply logic (as same I applied for changing the text color of question statement). The logic should be like, if the selected answer is correct, the box should be highlight with green backGroundColor, if wrong then should highlight with RED BackGroundColor.

If you want this kind of structure, I can help you.. :)

[Prashanth Damojipurapu]

Sure, That would be Great. Thank you. Can you send me the logic?

[Shameer Parmar]

Prashanth,

Please find attached updated Question format..

[Prashanth Damojipurapu]

Thank you.

I got a small error while running the file. In my files i included a previous button. Score is being counted twice,if the user goes previous question selects the correct choice and goes to the next question.

I need to change the code but i don't know how.

Can you help me that ??
