I have been having problems with wxPython ‘4.1.1 gtk3 (phoenix) wxWidgets 3.1.5’ on Linux. Specifically with a custom wizard (i.e. no wx.adv.Wizard) I created for my software (relax). To double check this, I pulled out the ‘Generic Wizard’ code from Mike Driscoll’s book “wxPython Recipes”:
import wx
"""From wxPython Recipes by Mike Driscoll, page 66-68."""
class WizardPage(wx.Panel):
"""A Simple wizard page"""
def __init__(self, parent, title=None):
"""Constructor"""
wx.Panel.__init__(self, parent)
sizer = wx.BoxSizer(wx.VERTICAL)
self.SetSizer(sizer)
if title:
title = wx.StaticText(self, -1, title)
title.SetFont(wx.Font(18, wx.SWISS, wx.NORMAL, wx.BOLD))
sizer.Add(title, 0, wx.ALIGN_CENTER|wx.ALL, 5)
sizer.Add(wx.StaticLine(self, -1), 0, wx.EXPAND|wx.ALL, 5)
class WizardPanel(wx.Panel):
""""""
def __init__(self, parent):
"""Constructor"""
wx.Panel.__init__(self, parent=parent)
self.pages = []
self.page_num = 0
self.mainSizer = wx.BoxSizer(wx.VERTICAL)
self.panelSizer = wx.BoxSizer(wx.VERTICAL)
btnSizer = wx.BoxSizer(wx.HORIZONTAL)
# add prev/next buttons
self.prevBtn = wx.Button(self, label="Previous")
self.prevBtn.Bind(wx.EVT_BUTTON, self.onPrev)
#btnSizer.Add(self.prevBtn, 0, wx.ALL|wx.ALIGN_RIGHT, 5)
btnSizer.Add(self.prevBtn, 0, wx.ALL, 5)
self.nextBtn = wx.Button(self, label="Next")
self.nextBtn.Bind(wx.EVT_BUTTON, self.onNext)
#btnSizer.Add(self.nextBtn, 0, wx.ALL|wx.ALIGN_RIGHT, 5)
btnSizer.Add(self.nextBtn, 0, wx.ALL, 5)
# finish layout
self.mainSizer.Add(self.panelSizer, 1, wx.EXPAND)
self.mainSizer.Add(btnSizer, 0, wx.ALIGN_RIGHT)
self.SetSizer(self.mainSizer)
def addPage(self, title=None):

else:
print("End of pages!")
if self.nextBtn.GetLabel() == "Finish":

pageCount = len(self.pages)
if self.page_num-1 != -1:

self.panelSizer.Layout()
else:
print("You're already on the first page!")
class MainFrame(wx.Frame):
""""""
def __init__(self):
"""Constructor"""
wx.Frame.__init__(self, None, title="Generic Wizard", size=(800,600))
self.panel = WizardPanel(self)
self.panel.addPage("Page 1")
self.panel.addPage("Page 2")
self.panel.addPage("Page 3")
self.Show()
if __name__ == "__main__":
app = wx.App(False)
frame = MainFrame()
app.MainLoop()
This clearly shows the problem. The first page of the wizard shows “Page 1”, the second only shows part of the text of “Page 2” so that it looks more like “Par”. Is this a known issue with 4.1.1? Or is there a new way to force a refresh/update/layout of the panels?
Cheers,
Edward
Thanks!
