MATLAB: How to execute checkbox callback by using pushbutton callback

guiguidelistboxmatlab gui

Hi,

I will be thankful if you could help me in this. I am new to matlab, i would like to click the pushbutton and in the same time it should execute the checkbox or listbox callback(similar to clicking the checkbox/listbox). How can i do this.

Best Answer

h = HandleOfOtherControl;
cb = get(h, 'Callback');  %this retrieves the callback
cb{1}(h, [], cb{2:end});  %this invokes the callback

Warning to other readers: this sequence will not work for callbacks constructed by GUIDE, as those use are strings instead of cell arrays of that contain the function handle. Fortunately Karthick KJ does not appear to be using GUIDE (or at least has not mentioned using GUIDE in any posting.)

MATLAB: Create a function to press button (instead of a function calling the callback function of the button)

Hi,

Thank you for your answer. I mainly needed the trick to get the callback name and arguments of a button, using

cb  = get(handles.button, 'Callback');

Now I would like to call the callback specified in the handles, for example:

   cb{1} = @gui_clusterGC2/tbutton_ISILFD

using the arguments in cb{2:end}. Is there a quick way to do this? -> I guess I can simply do:

cb{1}([],[],cb{2:end})

This works :)

Thank you!

You are passing a function handle to feval, and the function handle requires two arguments, but you are not providing any arguments.

file_browse_button_handle = findall('Tag', 'File_browse');
cb = get(file_browse_button_handle, 'Callback');
%now invoke the callback. hObject will be the button's own handle
cb(file_browse_button_handle, []);    %uicontrol pushbutton have empty event
