Sizer problem with AUI and PyPlot

wxPython Users

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

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

There might be 2 issues here, and I don't know which one applies. The
first one is, use wx.Panel instead of wx.Window to hold your PyPlot.
Second one, I don't know if PyPlot implements DoGetBestSize. If it
doesn't, the sizer doesn't know which size to allocate to PyPlot.

There might be 2 issues here, and I don't know which one applies. The
first one is, use wx.Panel instead of wx.Window to hold your PyPlot.

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.

Second one, I don't know if PyPlot implements DoGetBestSize. If it
doesn't, the sizer doesn't know which size to allocate to PyPlot.

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.
