Is there a way to create non-bordered transparent windows in Python?

Question

I am trying to make a widget-style application in Python, and I have tried searching around but I have not found a GUI toolkit that allows you to hide borders and remove the window background (fully transparent, only content rendered).

Is there a Python GUI toolkit with the following features?:

• No window borders.
• Completely transparent background.
• Non-OS specific GUI control rendering (custom bitmaps, fonts, etc).
• Event Detection (click, keyboard, etc)
• Window Management (always on top, steal focus, etc)

Answer 1

Yes, wxpython can do this. Look at the ShapedWindow example in the Demo application (available on the download page).

Answer 2

It's been a little while since I've done things like that, but I would think that most GUI toolkits would allow you to do that. For example, GTK+ has Python bindings, and should support all of that.

Here's an example of using GTK+ to draw transparent content with GUI controls.

I have even less experience with them, but I think wxWidgets and Qt/KDE have similar functionality.
