I've made a small program in python for the viewing of images.It runs perfectly as a standalone program, but when I convert it into Sugar, it runs in a different window coz of which it cannot be stopped.I have to close Xephyr and run it again.I use Sugar .88 on Ubuntu 9.10 KarmicCould anyone please help me?

Python-tk is not being installed on most systems running Sugar (see the Sugar Platform page [1] for a list of packages that should be available on all systems). Also with GTK it will be much easier to integrate into Sugar; you can use several GTK-based widgets made specifically for Sugar (the sugar.graphics submodules on [2]), in addition to the regular activity framework (sugar.activity) that I highly recommend to build on. It'll make Sugar integration much easier.

Polyol[4] is designed exactly for this purpose, these are C libraries
that should cover all sugar related low level routines, starting from
getting sugar environment settings via full featured sugar GUI to high
level stuff i.e. what sugar-toolkit does for python based activities.
It is not yet finished (but already in some useful stage, I'm using it
for C based GCompris and less for Tuxpaint) and contains only python
binding for now.
