Scroll the scripts window (2.49b)

Coding Python Support
1

I wasn’t sure if should post this here or in the interface forum but I thought here would be more appropriate. I apologize if this not the appropriate forum. I am using Blender 2.49b.

I’m writing a Python script that draws a large number of button objects, which don’t all fit in the scripts window, even when it is zoomed to full size. However, I can’t figure out a way to scroll the scripts window. I can scroll the buttons window with the middle mouse button but I can’t do this in the scripts window. The page http://www.blender.org/documentation/249PythonDoc/Draw-module.html says that the Draw module’s widgets include a scrollbar but I couldn’t find any more information about it on that page. I found some information about it through the doc member in the interactive python console but when I added a scrollbar object it had no effect. I’m not sure if the scrollbar object is what I wanted anyway. Is there a way to scroll the scripts window, or get python to add a way to scroll it?

You can take a look at my scrollable list box, if you like.

Hi, I have been looking at this code for creating a Window to be scrollable. But I am not familiar with Blender BGL. And I its hard to follow it because I am not that good with Blender Python.

Is there another alternative to scroll the Entire Window with the usual Blender.Draw GUI widgets… But I think I can try to code it

I managed to solved it, I just messed around then I thought that I can mimic scrolling by just moving all the GUI Widgets on my windowFrame using MouseScroll button events.

I tried writing brief comments but feel free to ask anything. :RocknRoll:
