wxPython - resizing a MatPlotLib FigureCanvas in a ScrolledPanel
I have a figure canvas in a ScrolledPanel in a Panel. I want to change the size of the figure canvas. E.g.
mplFigure.set_figheight(1.0)
someobject.soSomethingThatResizeItAll
How can I do this?
Thanks

Here's my construction code.
panel = wx.Panel(self) # we put the scrollablePanel in the panel so later on we can do fit to window sizing too (i.e. by removing the scrollablePanel)
# create a scrollablePanel to hold the canvas
scrollablePanel = ScrolledPanel(parent=panel, id=wx.ID_ANY, name="scrolledPanel", style=wx.ALWAYS_SHOW_SB)
scrollablePanel.SetupScrolling()
scrollablePanel.SetBackgroundColour(wx.Colour(128,128,128))
# create mpl canvas and figure
mplFigure = Figure(figsize=A6H, facecolor="white") #, edgecolor="black")
mplFigureCanvas = FigureCanvasWxAgg(parent=scrollablePanel, id=wx.ID_ANY, figure=mplFigure)
#mplFigureCanvas.SetWindowSt开发者_如何学JAVAyle=wx.SIMPLE_BORDER # not sure if this will have any affect?
#mplFigureCanvas.SetBackgroundColour(wx.Colour(0,0,0))
# center the FigureCanvas inthe scrollablePanel
sizer1 = wx.BoxSizer(wx.VERTICAL)
sizer1.Add(mplFigureCanvas, proportion=0, flag=wx.ALL|wx.ALIGN_CENTER_HORIZONTAL, border=8)
sizer2 = wx.BoxSizer(wx.HORIZONTAL)
sizer2.Add(sizer1, proportion=1, flag=wx.ALIGN_CENTER_VERTICAL)
scrollablePanel.SetSizer(sizer2)
# create mpl toolbar
#mplToolbar = NavigationToolbar2Wx(mplFigureCanvas)
#mplToolbar.Realize() # needed to support Windows systems
# use another sizer to add the scrollablePanel to the main panel
sizer = wx.BoxSizer(wx.VERTICAL)
sizer.Add(scrollablePanel, 1, wx.LEFT | wx.EXPAND)
#sizer.Add(mplToolbar, 0, wx.LEFT | wx.EXPAND)
#mplToolbar.Show()
panel.SetSizer(sizer)
Well I now have some horrible code that gets the result but it's not pretty.
mplFigure.set_size_inches(sizeInInches)
l,b,w,h = mplFigure.bbox.bounds
w = int(math.ceil(w))
h = int(math.ceil(h))
mplCanvas.SetInitialSize(size=wx.Size(w, h))
size = panel.Size
panel.SetSize(wx.Size(size.x, size.y-1))
panel.SetSize(wx.Size(size.x, size.y))
An improvement would be welcome.

Well I've found part of the answer.
mplFigureCanvas.SetSize(...)
does it initially but as soon as I resize the frame it goes back to the original size.

If I understand your question correctly I think you'll want to set up your panels differently. I would put the mpl_canvas
in a wx.Panel
and then put that panel into the ScrolledPanel
. Then to enlarge/shrink the canvas just update the MinSize
of the panel (panel.SetMinSize()
).
