MATLAB: Does someone know if it’s possible to have popupmenu in inputdlg

inputdlg uicontrol

Hello,

I am familiar with the use of inputdlg but unfortunately the input fields accept only text and numbers! does someone know if it's possible to have popupmunu or listbox so I can select among a list of possible inputs?

Thank you, Aleksandar

Absolutely you can, however its not as straight forward as inputdlg() or questdlg(). you'll want to look at the example here:

which is pretty much the same example i was about code out for you.

You are right about the idea of a GUI to implement the interface you want. Developing a GUI application in MATLAB is not that hard, especially with the help of GUIDE. You can find useful tutorial here. http://blogs.mathworks.com/videos/category/gui-or-guide/. The GUI application can also be compiled to an .exe file since you have the MATLAB Compiler Toolbox.

GUI application is not "jump to the beginning of the code and make the changes initiated by the control panel" though. GUI application is kind of event-driven. Once the user clicks a button, or selects a list, the corresponding code is executed to make things happen.

You could still do what you want with your current code. You could add your code inside a while-loop. With some function like questdlg(),listdlg(), etc. you can check the user input. If the user choose certain input, you can control your program to run for again and again. If the user choose to exit, then you can terminate the execution of your program.

Cancel and OK are hardcoded in inputdlg

OKHandle=uicontrol(InputFig     ,              ...
  BtnInfo      , ...
  'Position'   ,[ FigWidth-2*BtnWidth-2*DefOffset DefOffset BtnWidth BtnHeight ] , ...
  'KeyPressFcn',@doControlKeyPress , ...
  'String'     ,'OK'        , ...
  'Callback'   ,@doCallback , ...
  'Tag'        ,'OK'        , ...
  'UserData'   ,'OK'          ...
  );
setdefaultbutton(InputFig, OKHandle);
CancelHandle=uicontrol(InputFig     ,              ...
  BtnInfo      , ...
  'Position'   ,[ FigWidth-BtnWidth-DefOffset DefOffset BtnWidth BtnHeight ]           , ...
  'KeyPressFcn',@doControlKeyPress            , ...
  'String'     ,xlate('Cancel', '-s')    , ...
  'Callback'   ,@doCallback , ...
  'Tag'        ,'Cancel'    , ...
  'UserData'   ,'Cancel'      ...
  ); %#ok

Above is code from inputdlg.m.

If you change in inputdlg.m, it will affect all inputdlg usages.

Check other similar functions if they are useful.

   dialog, errordlg, helpdlg, listdlg, msgbox,
       questdlg, textwrap, uiwait, warndlg
