How to use a png image as a toolbar button icon?

[steve]

I have some set of png images, I'd like to use them as button icons in my toolbar (wx.ToolBar).

 

I do:

 

ID_DRAW_BUTTON = 100

self.toolbar = wx.ToolBar(self, -1, style=wx.TB_FLAT|wx.BORDER_RAISED)

 

draw_icon = wx.ArtProvider.GetBitmap("chart-icon", wx.ART_TOOLBAR, (16,16))

self.toolbar.AddTool(ID_DRAW_BUTTON, "Draw", draw_icon, shortHelpString="Draw Chart")

 

But it says

 

TypeError: in method 'ToolBarBase_DoAddTool', expected argument 4 of type 'wxBitmap const &'

 

although type of draw_icon is <class 'wx._gdi.Bitmap'>

 

So what should I do to use a png image as a toolbar button  icon?

What wxPython version?

Isn't arg 4 the disabled bitmap?  If you haven't one you can pass NullBitmap.

try this. wx3.0.2 call
wx.ToolBar.AddTool(self, id, bitmap=mybitmap, pushedBitmap=mybitmap, isToggle=0, clientData=None, shortHelpString='', longHelpString='')
It might differ a bit on older wxversions as far as arg placement or args.

I'm not sure the following is actually helpful.  I have tried several methods (in the general use of the word not python method) of adding graphics (png,jpeg, icon, etc..) to toolbar panels.  What I discovered was that in the end I needed a button.  Once I started using buttons all worked well and as expected.  Playing with the background and pic I got very good results.  So try something like:

self.clearbtn = wx.Button(self, -1,label = 'Clear' )
self.clearbtn.SetBackgroundColour(wx.CYAN)
self.clearbtn.SetBitmap(wx.Bitmap('icons/edit-clear32.png'),wx.LEFT)

then add the button to the toolbar.
