Splitter+panel with foldpanelbars inside - trouble :| (source)

[w.p11]

I have some trouble with my GUI. I have left panel with foldpanelbar,
but i need one item but not collapsed - simple button. I split my left
panel into two foldpanelbars with one button between.

But a have trouble... Panels are to small, tree is too short..
Sorry for english

The FoldPanelBar doesn't report it's best size, so it can't be used with a sizer in the way you are trying to do. (See http://wiki.wxpython.org/index.cgi/WindowSizeInfo) You can probably make it work if you set the min size of the FPB's yourself but that would need to be redone as the FPB changes size as new panel items are shown or hidden. My suggestion is to either put all of your items in a single FPB or use another splitter on the left side where each half of the splitter holds 1 FPB.

The problem of using a FPB in a sizer like this is fixable however.
If anybody feels like learning more about how sizers use the best size, you can add a DoGetBestSize method to FPB (and change FPB to derive from wx.PyPanel) and then submit your change to me as a patch file.
