How to close wxGrid located inside wxFrame

[Pekka Niiranen]

Hi,

    how should I define the OnExit -method in MainFrame -class below
    so that wxWindows would not leak memory, when "Exit" is selected
    from the menu. I should somehow close the grid before the frame, but
how ?

from wxPython.wx import *
from wxPython.grid import *
from wxPython.lib.mixins.grid import wxGridAutoEditMixin
import sys, pprint

ID_EXIT  = 102

class PnGrid(wxGrid):
    def __init__(self, parent):
        wxGrid.__init__(self, parent, -1)
        self.moveTo = None
        EVT_IDLE(self, self.OnIdle)
        self.CreateGrid(25, 25)

        .... lots of code...copied from wxWindows demofile
SimpleGrid.py...

class MainFrame(wxFrame):
    """ Creates and initializes the main window"""

    def __init__(self, parent, id, title, style):
        # First, call the base class' __init__ method to create the
frame
        wxFrame.__init__(self, parent, id, title, wxPoint(100, 100),
wxSize(640, 480), style)

        self.CreateStatusBar()
        self.SetStatusText("This is the statusbar")

        # Make menu with separate MakeMenus -method
        menu = self.MakeMenus()
        self.SetMenuBar(menu)

        # Associate some events with methods of this class
        EVT_MENU(self, ID_EXIT,  self.OnExit)

        # Create grid
        pn_grid = PnGrid(self)

    def MakeMenus(self):
        """Creates the menus of the main window"""

        # Filemenu contents
        filemenu = wxMenu()
        filemenu.Append(ID_EXIT, "Exit", "Terminate the program")

        # Collect all menus
        main = wxMenuBar()
        main.Append(filemenu, "File")
        return main

    def OnExit(self, event):
        # Close program
        self.Close(true)


class MainApp(wxApp):
    # wxWindows calls this method to initialize the application
    def OnInit(self):

    # Create an instance of our customized Frame class
        frame = MainFrame(NULL, -1, " PnGrid", wxSTAY_ON_TOP |
wxCAPTION)
        frame.Show(true)

    # Tell wxWindows that this is our main window
        self.SetTopWindow(frame)
        return true

if __name__ == "__main__":
    app = MainApp(0)
    app.MainLoop()
