Yair,

I figured out my request. Posting it here for anyone else who may be curious.

Thanks again!
Meade

 import com.mathworks.mlwidgets.graphics.ColorPicker
 cp = ColorPicker(ColorPicker.AUTO, ColorPicker.LINE_ICON, '');
 [jcp,hcontainer] = javacomponent(cp,[],gcf);
 
 % !! Here's the key bit... This will trigger when user picks a color & selects "OK" in widget
 set(jcp, 'ItemStateChangedCallback', {@MyCallback,gcf})


 function MyCallback(hObj,evt,hFigure)
      color = cp.getValue;  % a java.awt.Color object % This should be within the callback
      color = cp.getValue.getColorComponents([])' * 255;   % an [R,G,B] array of values
      % Do something with the color
 end %MyCallback

Another super useful post I’m just now finding!

I have embedded this color picker within a context menu of a GUI I’ve built.
My question is this:
Is it possible to trigger a callback when the user clicks ‘OK’ in the widget?
Using the code snippet you provided for @Red Kim, hopefully my intention is clear.

Thanks so much for all the great insights.
Best,
meade

import com.mathworks.mlwidgets.graphics.ColorPicker
cp = ColorPicker(ColorPicker.AUTO, ColorPicker.LINE_ICON, '');
[jcp,hcontainer] = javacomponent(cp,[],gcf);   % Need to trigger callback on selection here!

% function MyCallback(hObj,evt)
color = cp.getValue;  % a java.awt.Color object % This should be within the callback
color = cp.getValue.getColorComponents([])' * 255;   % an [R,G,B] array of values
% Do something with the color
% end %MyCallback

@Paul – you can use the following object methods to retrieve the com.mathworks.beans.editors.ColorPicker‘s selected color:

* getBlue() % returns int
* getGreen() % returns int
* getRed() % returns int
* getSelectedColor() % returns java.awt.Color

Red Kim referred to a different ColorPicker class (that happens to have the same class name), but it’s a different class in a different package so of course it has different behavior.

@ronin – I am not aware of a way to do this.

Thanks in advance

Thank you so much!!
It’s working now!
Your amazing guy!!

@Kim –

import com.mathworks.mlwidgets.graphics.ColorPicker
cp = ColorPicker(ColorPicker.AUTO, ColorPicker.LINE_ICON, '');
[jcp,hcontainer] = javacomponent(cp,[],gcf);
color = cp.getValue;  % a java.awt.Color object
color = cp.getValue.getColorComponents([])' * 255;   % an [R,G,B] array of values

More information about ColorPicker, including its options and icons styles, can be found in section 5.4.1 of my Matlab-Java book.
