Re: [wxPython-users] Sizer problem with AUI and PyPlot

[Stef Mientki]

thanks Cristopher and Andrea,
Panel instead of Window seems todo the trick,
I looks that the PyPlot is spreding over the "window" ,
although I don't see any signals yet, but there's another bug somewhere,
I'll see tomorrow.

cheers,
Stef

hello,

I'm trying to put PyPlot on an AUI-window,
so it will fill the whole window,
but the code below (with or without boxsizer),
just gives a very small PyPlot window 30*30 pixels or so in the upper
left corner.

class Control_Pane ( wx.Window ):
def __init__ ( self, parent, Brick, Title = 'Edit Values Below',
Help = '' ) :
wx.Window.__init__ ( self, parent )

self.Canvas = plot.PlotCanvas ( self )
self.Canvas.SetEnableGrid ( True )
self.Canvas.SetYSpec ( 'auto' )

#self.AutoLayout()
sizer = wx.BoxSizer()
sizer.Add(self.Canvas, 1, wx.EXPAND)
self.SetSizer(sizer)
self.Fit()

What am I doing wrong ?
Or even better, how should I do it right ?

thanks,
Stef Mientki

For the record this is because wx.Window's default EVT_SIZE handler does
not do the auto layout, because it does not make sense for *all* of the
descendants of wx.Window to inherit this behavior, so only those that
are intended to be containers do it. If you ever do want to have a
wx.Window that does auto layout with a sizer, all you need to do is just
give it a EVT_SIZE handler that calls self.Layout.

Since it is getting added to the sizer with proportion=1 and
flags=wx.EXPAND it doesn't need to have a DoGetBestSize. But even if it
wasn't set to fill the all sizer's allotted space like this you can work
around the lack of a DoGetBestSize simply by calling SetMinSize with
whatever you want the minimum to be.
