Minor issue with NewColorPickerMorph and question about Object>>changed: and how to debug

In the NewColorPickerMorph if you scale the alpha of the selected color, the UI will not turn let you set alpha back to fully opaque. You can pull the slider all the way to the max but the selected color will remain translucent.

This is a minor issue but the big issue is how do debug this and similar issues which is set up with the Object>>update: or Object>>changed:

I find that I'm going into a rabbit hole each time I try to debug these message sends. I can't seem to get a grip on what or where the messages and changes in state are from.

Do anybody have any advise on good practice for debugging Object>>update: or Object>>changed: ?

Best,

Karl

btw, there is an open issue on mantis for the NewColorPicker
http://bugs.squeak.org/view.php?id=7753
NewColorPickerMorph can not be used to change colors re erase
colors from a SketchMorph.
The Menu entries
"erase pixels of color" and
"recolor pixels of color" raise a DNU.

Changing a GradientFill color from within the
fill style menu (for any morph) doesn't work as well.

I hear you about trying to debug the Listener pattern, its a pain.

One thing I do when I can't use the debugger is create a global
"object log" -- an OrderedCollection -- and then, in Object>>#update:
(or whereever) capture the current stack into your log:

MyGlobalLog add: thisContext longStack

Great tips.

I'll take a look at that.

Changing colors in a Sketch is quite a special case, though.

Changing a GradientFill color from within the
fill style menu (for any morph) doesn't work as well.

Have you looked at the latest trunk where I have contributed a special tool for editing colors in gradients ?

Thanks.

I don't know for what I needed this, the bug report is two years old :)

No, just checked the current release
