Scrollbar questions

Hi, dear all,

how can I make scrollbars working with a big grid?

With the appended code, the horizontal scrollbar is visible but ‘too long’ (it exceeds the visible area and can’t be moved), the vertical is missing at all.

I’m working on Windows with Python 2.7 and WxPython 2.8.

(I’ve tried FlexGridSizer and GridBagSizer, too, but there the situation is even worse: no scrollbars at all…)

Thanks for all help from

I’d bet you have a sizer problem such that the bottom of the vertical scroll bar and the entire horizontal scroll bar are hidden and not visible.

Hi, David,

that may easily be… but I can’t solve that problem, I can’t even find it. To me, it seems everything okay. What is going wrong, where is the problem located?

Thanks for all help,

Obviously, it is a sizer problem.

If one runs the attached code as it is, scrollbars appear and work.

If one uncomments the tree lines for the secondsizer and comments out ‘self.SetSizer(sizer)’, all scrollbars vanish.

But if I need scrollbars in a subordniated panel… what can I do then? (And… should it really behave like this, or looks it a bit like a bug?)

Any help would be appreciated.

Add “self.SetAutoLayout(True)” to your MainPanel.init()
method.

Thanks for the advice! I did so, but unfortunaltely could detect no difference between the behaviour without and with the setting. Still the scrollbars are only there in the version with only one sizer, but vanish as soon as I insert the second one.
