Hi.

I wrote these Widgets and the Morphic Designer mostly from scratch. There is almost no stacking of libraries. ;)

Widgets need Signals and Animations which I also wrote from scratch and which do not have any dependencies other than Squeak 4.1 and later.

For now, I reused:

- PluggableTextMorph
- TextMorphForEditView
- ScrollBar
- ScrollPane

These I plan to replace them with new ones as well.

The code itself is MIT licensed as stated here.

I did the whole thing, because I did not like, how the classic tool builder works or how pluggable morphs are meant to be used.

Signals could definitely be integrated into Squeak (trunk) because I fixed the last serious bugs back in the last months as I worked with signals in several projects in a productive way.

Obviously, I adapted the API and some great ideas of the Nokia/Qt Framework. So you could say that some widgets or the signals are just a port from C++ to Squeak. There shouldn't be any licensing issues.

All widgets use several icon packages that are also meant to be used for community purposes and reflect the correct license at source code level just now:
