Se the guess below. Could be you aren't sending a proper parent

Subject: [wxPython] stored dialogs

Hello

I'd like to write a generic dialog with 'customizable' sub-dialogs
but I can't use the 'stored' dialog after the first invokation of
wxDialog.ShowModel().

Even the close-button in the title-bar doesn't work - only ESC is
recognized. I wonder whether I'm doing something wrong or whether
there's a bug in the event system.

I've written a small demo in order to illustrate some problems:
(wxPython 2.2.2, Python 1.5.2 (2.0 crashes ), NT4 SP6)

from wxPython import wx

# This is just a boring utility function.
def init_panel_with_sizer_and_widget(panel, sizer, widget):
    sizer.Add(widget, 1, wx.wxEXPAND)
    panel.SetSizer(sizer)
    panel.SetAutoLayout(1)
    sizer.Fit(panel)
    sizer.SetSizeHints(panel)

# This dialog will be created and stored in a more complex dialog.
class SimpleDialog(wx.wxDialog):

    def __init__(self, parent):
        wx.wxDialog.__init__(
            self, parent, -1, 'SimpleDialog',
            style=wx.wxDEFAULT_DIALOG_STYLE|wx.wxRESIZE_BORDER)
        button = wx.wxButton(self, wx.wxID_CANCEL, 'Press ESC if broken.')
        init_panel_with_sizer_and_widget(
            self, wx.wxBoxSizer(wx.wxVERTICAL), button)

class TestDialog(wx.wxDialog):

    def __init__(self, parent=None):
        wx.wxDialog.__init__(
            self, parent, -1, 'wxDialog',
            style=wx.wxDEFAULT_DIALOG_STYLE|wx.wxRESIZE_BORDER)

        panel = wx.wxPanel(self, -1)
        box = wx.wxStaticBox(panel, -1, '')
        inner_panel = wx.wxPanel(panel, -1) # Or should "box" be the parent?
        inner_panel.SetBackgroundColour(wx.wxColour(0, 0, 0))
        inner_panel.SetForegroundColour(wx.wxColour(255, 255, 255))
        lbl_info = wx.wxStaticText(inner_panel, -1, """
        The 'stored dialog' can only be used after the second
        invocation. The 'generated' dialog works as expected.
        Why? (Btw: it works if the parent is a wxFrame)

        The inner panel is taller than expected.
        The StaticBoxSizer doesn't seem to expect an empty title.

        After resizing the dialog the inner panel is even taller and
        the right button isn't repainted properly.

        I have the impression that the right button is copied to its
        new position after the original position was overwritten by the
        'new' left button.
        """)

        init_panel_with_sizer_and_widget(
            inner_panel, wx.wxStaticBoxSizer(box, wx.wxVERTICAL), lbl_info)
        init_panel_with_sizer_and_widget(
            panel, wx.wxStaticBoxSizer(box, wx.wxVERTICAL), inner_panel)

        btn_stored = wx.wxButton(self, -1, '&Stored Dialog')
        btn_generated = wx.wxButton(self, -1, '&Generated Dialog')

        h_sizer = wx.wxBoxSizer(wx.wxHORIZONTAL)
        h_sizer.Add(btn_stored)
        h_sizer.Add(btn_generated, 0, wx.wxLEFT, 5)

        sizer = wx.wxBoxSizer(wx.wxVERTICAL)
        sizer.Add(panel, 1, wx.wxEXPAND|wx.wxALL, 5)
        sizer.Add(h_sizer, 0, wx.wxALIGN_RIGHT|wx.wxALL^wx.wxTOP, 5)
        self.SetSizer(sizer)
        self.SetAutoLayout(1)
        sizer.Fit(self)
        sizer.SetSizeHints(self)

!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Just a guess but try < stored_dialog = SimpleDialog(self) >
instead of
        stored_dialog = SimpleDialog(parent)
!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

        def open_stored_dialog(event, dlg=stored_dialog):
            dlg.ShowModal()
        wx.EVT_BUTTON(self, btn_stored.GetId(), open_stored_dialog)

        def open_generated_dialog(event, parent=parent):
            SimpleDialog(parent).ShowModal()
        wx.EVT_BUTTON(self, btn_generated.GetId(), open_generated_dialog)

if __name__ == '__main__':

app = wx.wxPySimpleApp()
TestDialog().ShowModal()
