I've started building my application around the idea of a main tabbed
window with a few small child windows spawned, and it seems to be working,
but with one problem. Sometimes, when I quit PythonCard, it appears to
hang for a few seconds, and the Python GUI environment crashes. Mac OS X
presents a dialog saying that Python has unexpectedly quit, and the
terminal shows a 'bus error.' This happens about 50% of the time when I
quit my app, but I haven't yet taken the time to nail down a pattern. It
may happen more when I spawn child windows.
I haven't see this problem yet under Windows XP.
Here is how I'm initializing the main window, based on the testNotebook.py
sample code:
class MainWindow(model.Background):
def on_initialize(self, event):
# if you have any initialization
# including sizer setup, do it here
self.printer = HtmlEasyPrinting()
# self.loadConfig()
self.startTitle = self.title
win2 = model.childWindow(self.components.notebook,
widgets.WidgetsTest)
self.components.notebook.AddPage(win2, 'widgets', True)
win3 = model.childWindow(self.components.notebook,
doodle.Doodle)
self.components.notebook.AddPage(win3, 'doodle', True)
win4 = model.childWindow(self.components.notebook,
tabEmp.MyBackground)
self.components.notebook.AddPage(win4, 'Employees', True)
win5 = model.childWindow(self.components.notebook,
tabMainMenu.MyBackground)
self.components.notebook.AddPage(win5, 'Main', True)
page = self.components.notebook.getPage(3)
size = page.size
wx.CallAfter(page.SetSize, size)
print "number of pages:",
self.components.notebook.getPageCount()
print "last page text: %s\n" % \
self.components.notebook.getPageText(self.components.notebook.getPageCount()
- 1)
print "stringSelection:",
self.components.notebook.stringSelection
self.components.notebook.stringSelection = 'Main' |
