ColorEditor progress

I have to clean the code and tweak things, but there is enough progress to share it with you.

The smaller color swatch is the closest CSS3 color and name (need to add its RGB value).

Obviously the package now requires CSS3-NamedColors.pck.st

Again,
  select a Morph
  open its menu and select "Show my Drop Target"
  click on the focus ring in the ColorPane
  drop on the DropTargetMorph

Enjoy!

Nice!
It will allow us to change the desktop background?
thanks

You can change the Color of the background.

Just control-click to select the PasteUpMorph,
  select "Show my Drop Target" from the menu,
  move the DropTargetMorph aside a bit to expose the ColorEditorWindow
  click on the focus color and drag to the drop target
and ... new desktop color!

It is good to know how to change the background picture.

Somebody (who me?) should add a menu item to the PasteUpMorph when we get a chance.

I have not seen documentation.

There is a basic problem with multiple projects when changing worlds (i.e. which PasteUpMorph is the "world" at the current time).  So what World are you in?

There is an assumption in the code that worlds form a tree:

PasteUpMorph>>world
        worldState ifNil: [^super world].
        ^self

Typically we are not making use of multiple worlds in Cuis, but I know of no reason not to.

I really don't know.  We do have a singleton Display (a DisplayScreen).

At Apple, we used to use multiple displays (CRTs) connected to a single computer and one could drag windows between them.  So a world might have multiple displays, but that is rare these days.

Another thought is synchronization between multiple global dictionaries.

But these are problems we currently do not have.

The code is pervasive enough that it must have solved a problem at one time.  It would be good to know the problem context.

Perhaps a posting on the Squeak and/or Pharo mailing lists (which I do not read) would be helpful.

I do not know,

I have not seen documentation.

I was thinking in the examples at PasteUpMorph >>backgroundImageData: method.

Will fix them right way!

Yes, agree, but my doubt is more simple, as I said to Hannes in the other thread, we shouldn't have the current world pointed as "World" for easiest manipulation?

World is a global name. There's no such thing as the current world for the whole image. There could be several worlds, or none. Additionally, globals are bad, and reducing them is good. And absolute reference systems re bad too. Relative references are much better.

Maybe you can use #world or #runningWorld. These are relative references (to some morph, or some process).

Cheers,
Juan Vuletich
