ScrolledPanel scrolls without touching the ScrollBar

I found it myself now, finally after 3 hours.

ScrolledPanel.OnChildFocus() scrolls to the selected child. In my case this is not good, because the child itself has a lot of childs (textfields). So clicking one of these textfields at the bottom results in the fact that the parent panel (the child of the scrolledpanel) is scrolled to, putting the textfield out of sight again.

To remedy this, I overwrote ScrolledPanel.OnChildFocus() with this:

def OnChildFocus(self, evt):
     return

This works. I hope this doesn't violate or break some other things that are vital (?).

Best regards,

Hello,

I have a Notebook, which I put a NotebookPage into.
The notebook gets a scrolledpanel, which in turn gets a Panel. This last Panel contains some widgets, mostly labels and textfields.

Now if I scroll this ScrolledPanel down an want to click a textfield (or by clicking anywhere in the ScrolledPanel), the Scroll moves automaticall to the top again. So I'm not able to put anything in that textfield. If I scroll down again, and click the SAME textfield, it works fine. Clicking another textfield however, results in the same strange behaviour as described above.

Does anybody have an idea what this could come from?

Best regards,

Here's the relevant code of the notebookpage, just in case:

class page1(wx.NotebookPage):
    def __init__(self, parent, id):
        #wx.Panel.__init__(self, parent, -1)
        wx.NotebookPage.__init__(self, parent, -1)
        self.paths =

        #form panel
        self.createcenterpanel()

        mainsizer = wx.BoxSizer(wx.VERTICAL)
        mainsizer.Add(self.spanel, 1, wx.EXPAND)
        self.SetSizer(mainsizer)
        self.SetAutoLayout(True)

    def createcenterpanel(self):
        sizer = wx.BoxSizer(wx.VERTICAL)
        self.spanel = scroll.ScrolledPanel(self, -1)#, style=wx.RAISED_BORDER)
        formsizer = wx.BoxSizer(wx.VERTICAL)
        formsizer1 = wx.FlexGridSizer(0, 4, vgap=2, hgap=10)
        formpanel = wx.Panel(self.spanel, -1)
        formpanel.SetSizer(formsizer)
        formsizer.Add(formsizer1, 0, border=10)
        gui_util.addcontrols1(formpanel, formsizer1)

        sizer.Add(formpanel, 0, wx.EXPAND)
        sizer.Add((58,0), 0)
        self.spanel.SetSizer(sizer)
        self.spanel.SetAutoLayout(1)
        self.spanel.SetupScrolling()

the function gui_util.addcontrols1 is like this:

def addcontrols1(parent, sizer):
    text = wx.StaticText(parent, 1, LA.CAT_TITLE_1)
    text.SetForegroundColour('Blue')
    sizer.Add(text, 0, flag=wx.ALIGN_LEFT|wx.ALL, border=5)

    sizer.Add(wx.StaticText(parent, -1, LA.MARQ), 0, flag=wx.ALIGN_LEFT|wx.ALIGN_BOTTOM|wx.LEFT, border=5)
    sizer.Add(wx.ComboBox(parent, -1, '', choices=clist, size=(120,-1), style=wx.CB_DROPDOWN|wx.CB_SORT, name='marq'), 0, flag=wx.ALIGN_LEFT|wx.EXPAND|wx.LEFT, border=5)
