I have a a StaticLine separating some buttons in a StaticBoxSizer. For some reason the StaticLine does not initially draw and only shows up when the window is resized (covering the line). When the GridBagSizer that contains the button layout is outside of a StaticBoxSizer, it shows up with no problem. I have created a test GUI to demonstrate the problem. Any help is greatly appreciated.

Ian,
Works here on Slackware-14.1 (see attached screenshot), but the virtual
terminal showed this after I closed the application:
[rshepard@salmo ~]$ python test_gui.py swig/python detected a memory leak of type 'wxPyXmlSubclassFactory *', no
destructor found.
That should give you a starting point.
Perhaps it's related to Microsoft no longer supporting win7?

I get a similar image here on Win 8.1 with 3.0.0.0 MSW Classic. I also get the PyXmlSubclassFactory * error. It goes away when I comment out the “import wx.xrc” (it still works without that import)
It seems to be a known ‘safe’ bug… https://groups.google.com/d/msg/wxPython-users/984OzOdHQCc/zD_xMtLtgAMJ

Thanks for your responses. That is interesting, I do not get that error on my machine, although commenting “import wx.xrc” out does not change anything, so I don’t really need it. Based on the post Nathan linked to, that does not seem to be the issue. Any other ideas?

This works on wxPython 2.8.12, but that's besides the point.
I tried it with 2.9.4, got the error, and then re-did it with one change:
you are adding everything directly to the frame. Try placing a wxPanel as
the first object (and setting the sizer on that instead of the frame
itself) and then adding the various widgets to that panel, including the
staticLine. I partially tested it (didn't bother to deal with the sizers),
and the line showed up.

Great catch, I have a feeling that is the issue!
P.S. in case Che wasn’t clear enough, you’re creating your widgets with self as the parent, Che is saying to make a Panel and use that as the parent for all the widgets. You don’t need to set the Panel to the Frame, since you pass self (the Frame) to the Panel when you construct it.

Thank you for your suggestions, they made a lot of sense, but I still can’t seem to get it working. I added the panel with:
panel = wx.Panel(self, -1)
I then changed the object constructors to use panel instead of self, i.e.:
self.m_staticline1 = wx.StaticLine( panel, wx.ID_ANY, wx.DefaultPosition, wx.DefaultSize, wx.LI_HORIZONTAL )
I then laid out the panel as such:
panel.SetSizer( gbSizer_outer )
gbSizer_outer.Fit( panel )
panel.Layout()
Have I missed something? I’m not sure if I implemented your suggestion incorrectly, or if it didn’t work. Thanks for the help!

works for me, even just doing self=wx.Panel(self) after the wx.Frame.__init works
see the more-sane looking code (which works for me)
I did notice that the self.SetSizeHintsSz didn’t seem to be working to make the min size such that the widgets won’t be hidden (frame can’t be sized too small)… but I fixed that with gbSizer_outer.SetSizeHints(self) after setting the sizer

I made the changes you suggested to the sample app, and they work. I then tried to do the same thing to my actual application, and the problem persisted. I then realized in my actual application I am changing the color with:
self.SetBackgroundColour( wx.Colour( 197, 206, 209 ) )
When I add this to the sample app, the lines disappear again. Any ideas why? Thanks!

Hm that’s strange. I wonder why it wouldn’t work on my machine. The color isn’t the issue, because resize (hiding the line, and then unhiding the line) makes the line show up, and it is visible.

Hello all,
I tried the sample app on Win7 (64Bit), Python 2.7.8, wxPython 2.9.5 and have the same effect: The static line is only shown after minimizing.
Adding wx.CallLater(0, frame.Refresh) just before app.MainLoop() solves it. But i think this is just a workaround.
Torsten
Odd. Two things I could suggest trying (I haven't tried):
1) Try calling the SetBackgroundColour() on the panel. Currently, you're
calling it on the Frame. If this works, I don't understand why yet.
2) Try reparenting things such that the StaticBox is the parent of the
widgets, NOT the panel. To quote Robin Dunn from this list: "The
recommendation is now [wx2.9 +] to use a parent/child relationship between
the staticbox and the widgets contained in it,".

Torsten, you are correct. Adding the CallAfter does make them display correctly, although it is a work around. I am still curious what the cause is and how to fix it, but at least I now have a way to make it work, so thank you!
Che, I tried #1 with no luck. I may be misunderstanding what you mean for #2, but I tried swapping panel with analyzeImageBox in the widgets, like such:
self.analyzeImage = wx.Button( analyzeImageBox, wx.ID_ANY, u"Analyze Image", wx.DefaultPosition, wx.Size( 170,45 ), 0 )
but got an error saying an argument of type ‘wxWindow *’ was expected. Did I implement your suggestion correctly?

I believe the problem with #2 above is that you aren’t saving the StaticBox, which is what the parent should be, not the StaticBoxSizer. Split that line into two, and use the StaticBox object for the StaticBoxSizer constructor as well as for the other widgets.
