colormapeditor

Hi,

I would like to use colormapeditor inside a GUI, and I want a pause in the program that waits for me to finish with the colormap settings and then to continue in the code. I don't know how to make this pause, and to test if the user pressed OK, apply or other button inside colormapeditor. In other words I want to get the button that was pressed and then to continue in the code. Any suggestions?

Thanks,

Razvan

Quick way to fix the problem is:

colormapeditor;
pause;
%conntinue your code

With this, after the colormap editor appears, you can do whatever you need, then close it by clicking OK and after press any key to resume the program.

Thanks. I knew this was an option. Is there another way to continue the code, exactly when you press some button in the |colormapeditor| window, without needing to press another button after that? And how can I test if the user pressed Yes, Apply, or Cancel in the |colormapeditor| window?

Hi,

Adding a listener for the colormapeditor event EditorClosed works in 2023b (undocumented feature, so might stop working in a later release).

colormapeditor;
cme=getappdata(0,'CMEditor');
addlistener(cme.ColormapEditor,'EditorClosed',@(src,event)uiresume);
disp(string(datetime("now")) + ' colormapeditor opened')
uiwait % pause program, wait for callback uiresume
disp(string(datetime("now")) + ' colormapeditor closed')
