wxPython: How to handle event binding and Show() properly.
- by Gopal
Hi all,
I'm just starting out with wxPython and this is what I would like to do:
a) Show a Frame (with Panel inside it) and a button on that panel.
b) When I press the button, a dialog box pops up (where I can select from a choice).
c) When I press ok on dialog box, the dialog box should disappear (destroyed), but the original Frame+Panel+button are still there.
d) If I press that button again, the dialog box will reappear.
My code is given below. Unfortunately, I get the reverse effect. That is,
a) The Selection-Dialog box shows up first (i.e., without clicking on any button since the TopLevelframe+button is never shown).
b) When I click ok on dialog box, then the frame with button appears.
c) Clicking on button again has no effect (i.e., dialog box does not show up again).
What am I doing wrong ? It seems that as soon as the frame is initialized (even before the .Show() is called), the dialog box is initialized and shown automatically.
I am doing this using Eclipse+Pydev on WindowsXP with Python 2.6
============File:MainFile.py===============
import wx
import MyDialog #This is implemented in another file: MyDialog.py
class TopLevelFrame(wx.Frame):
def __init__(self,parent,id):
wx.Frame.__init__(self,parent,id,"Test",size=(300,200))
panel=wx.Panel(self)
button=wx.Button(panel, label='Show Dialog', pos=(130,20), size=(60,20))
# Bind EVENTS --> HANDLERS.
button.Bind(wx.EVT_BUTTON, MyDialog.start(self))
# Run the main loop to start program.
if __name__=='__main__':
app=wx.PySimpleApp()
TopLevelFrame(parent=None, id=-1).Show()
app.MainLoop()
============File:MyDialog.py===============
import wx
def start(parent):
inputbox = wx.SingleChoiceDialog(None,'Choose Fruit', 'Selection Title',
['apple','banana','orange','papaya'])
if inputbox.ShowModal()==wx.ID_OK:
answer = inputbox.GetStringSelection()
inputbox.Destroy()
