All,
Here is a similar situation:
import wx
ID_STAT = 1
ID_TOOL = 2
class CheckMenuItem(wx.Frame):
def __init__(self, parent, id, title):
wx.Frame.__init__(self, parent, id, title, size=(350, 250))
# create a menubar
menubar = wx.MenuBar()
# create file menu
file = wx.Menu()
# create view menu
view = wx.Menu()
# add items to view menu
self.shst = view.Append(ID_STAT, 'Show statusbar', 'Show statusbar',
kind=wx.ITEM_CHECK)
self.shtl = view.Append(ID_TOOL, 'Show toolbar', 'Show toolbar',
kind=wx.ITEM_CHECK)
view.Check(ID_STAT,True)
view.Check(ID_TOOL,True)
# bindings
self.Bind(wx.EVT_MENU,self.toggleStatusBar,id=ID_STAT)
# add menus to menubar
menubar.Append(file, '&File')
menubar.Append(view, '&View')
# add menubar to Frame
self.SetMenuBar(menubar)
# add toolbar
self.toolbar = self.CreateToolBar()
self.toolbar.AddLabelTool(3,'',wx.Bitmap('icons/calendar.png'))
self.toolbar.Realize()
# add status bar
self.statusbar = self.CreateStatusBar()
self.statusbar.Show()
# center and show frame
self.Centre()
self.Show()
def ToggleStatusBar(self,event):
if self.shst.IsChecked():
self.statusbar.Show()
else:
self.statusbar.Hide()
app = wx.App()
CheckMenuItem(None, -1, 'Check Menu Item')
app.MainLoop()
Because I wrote toggleStatusBar instead of ToggleStatusBar in my binding, the
GUI won't run, but no errors are reported anywhere in PyDev.
What can I do in this situation other than struggle manually to find this
little typo?
