Toolbar rendering following wxPython 2.9 upgrade - macos

Question

This code worked fine on wxPython 2.8, following an upgrade today to 2.9 however the toolbar doesn't
display at all. If I remove the self.SetToolBar() call the icon does show up but not as a button, and the toolbar formatting doesn't stretch when the screen is re-sized. Any ideas?
import wx
class MyApp(wx.App):
def OnInit(self):
self.frame = Example(None, title="Word Bag", size=(400,100))
self.SetTopWindow(self.frame)
self.frame.Show()
return True
class MyToolbar(wx.ToolBar):
"""Toolbars are attached to frames, so need TBar = Toolbar(self) in frame init"""
def __init__(self, parent):
wx.ToolBar.__init__(self, parent)
# set my preferred default size for icons
self.SetToolBitmapSize((32,32))
# the main bit where icons are formatted, added, and bound to handlers
self.initialiseIcons()
# Need to call realise before exiting
self.Realize()
def initialiseIcons(self):
"""Iterate over icons and add them to toolbar"""
for each in self.toolbarData():
self.createSimpleTool(*each)
def createSimpleTool(self, label, filename, statbar, handler):
"""Adds icons to bar using AddSimpleTool"""
if not label:
self.AddSeparator()
return
bmp = wx.Image(filename, wx.BITMAP_TYPE_PNG).ConvertToBitmap()
tool = self.AddSimpleTool(-1, bmp, label, statbar)
self.Bind(wx.EVT_MENU, handler, tool)
def toolbarData(self):
"""Put your icon data here in the following format...
[0] = tooltip label, [1] = bitmap path, [2] = status bar label, [3] = bound function"""
return [["Add new word","/Users/paulpatterson/Desktop/add.png","Add a new word to the dictionary",self.OnAddWord]]
# toolbar icon handlers here...
def OnAddWord(self, event):
pass
def OnRemoveWord(self, event):
pass
def OnSearchWord(self, event):
pass
class Example(wx.Frame):
def __init__(self, parent, title, size):
super(Example, self).__init__(parent, title=title, size=size)
# Create and set the toolbar
tBar = MyToolbar(self)
self.SetToolBar(tBar)
self.frameSizer = wx.BoxSizer(wx.VERTICAL)
self.panelOne = MyPanel(self)
self.frameSizer.Add(self.panelOne, 1, wx.EXPAND)
self.SetSizer(self.frameSizer)
#self.frameSizer.Fit(self)
self.Centre()
self.Show()
class MyPanel(wx.Panel):
def __init__(self, parent):
super(MyPanel, self).__init__(parent)
self.mainSizer = wx.BoxSizer(wx.VERTICAL)
### widgets here
# set optimum layout for mainsizer...
self.SetSizer(self.mainSizer)
# ...then fit main sizer to the panel.
self.mainSizer.Fit(self)
if __name__ == '__main__':
app = MyApp(False)
app.MainLoop()

I had the same problem just hours ago. I couldn't get a custom created toolbar to work, but using Frame.CreateToolBar() works as expected. Example:
class MyFrame(wx.Frame):
def __init__(self):
wx.Frame.__init__(
self, parent=None, id=-1, title='Test window',
size=wx.Size(800, 600)
)
self.setup_toolbar()
def setup_toolbar(self):
# First create the toolbar.
self.toolbar = self.CreateToolBar(wx.TB_FLAT | wx.TB_TEXT)
self.Bind(wx.EVT_TOOL, self.on_toolbar)
# Add a 'Clear all' button.
self.toolbar.AddLabelTool(
wx.ID_NEW, 'Clear all', get_toolbar_art('new_big'),
shortHelp='Remove all the contents from the text inputs.'
)
# Add an 'Open' button.
self.toolbar.AddLabelTool(
wx.ID_OPEN, 'From file...', get_toolbar_art('open_big'),
shortHelp='Fill the input box with the ' +
'contents of a Linjekort text file.'
)
# self.toolbar.AddSeparator() # A separator.
# Add a 'Save all' button.
self.toolbar.AddLabelTool(
wx.ID_SAVE, 'Save results to...', get_toolbar_art('save_big'),
shortHelp='Save all the Ozi files to a directory.'
)
self.toolbar.Realize()
def get_toolbar_art(name):
return wx.Bitmap('icons/{}.png'.format(name))
But this doesn't answer how to get a custom toolbar subclass to work. Have you tried to just add the toolbar to your layout using a sizer, not using the SetToolBar function? That's the only way I know of to avoid ending up with the OSX native Frame toolbar. Here's an example of that done:
def create_output_panel(self, parent, slug, label):
panel = wx.Panel(parent, style=wx.BORDER_THEME)
panel.SetBackgroundColour(
wx.SystemSettings.GetColour(wx.SYS_COLOUR_3DSHADOW)
)
# Toolbar.
toolbar = wx.ToolBar(panel, -1, style=wx.BORDER_RAISED)
toolbar.AddSimpleTool(
wx.ID_SAVE, get_toolbar_art('save'),
shortHelpString='Save to file...'
)
toolbar.Realize()
toolbar.Bind(wx.EVT_TOOL, lambda evt: print('Success'))
# Text control.
textctrl = wx.TextCtrl(
panel, -1, style=wx.TE_READONLY | wx.TE_MULTILINE | wx.BORDER_NONE
)
# Organize controls.
sizer = wx.BoxSizer(wx.VERTICAL)
sizer.Add(
wx.StaticText(panel, -1, label), proportion=0, border=5, flag=wx.ALL
)
sizer.Add(toolbar, proportion=0, flag=wx.EXPAND)
sizer.Add(textctrl, proportion=1, flag=wx.EXPAND)
panel.SetSizer(sizer)
return panel
And a screen shot:
I hope this helps!
