    <p><br/> Hi, everyone.<br/></p> <p>I have a little python GUI program based on wxPython 2.8.x.<br/> It create a wx.Dialog widget and show the dialog by calling ShowModal().<br/> At some situation, the wx.Dialog will show a wx.PopupWindow with a wx.ListCtrl locate inside.<br/> The wx.PopupWindow appears correctly, but trouble comes.<br/> wx.ListCtrl, and its parent widget, wx.PopupWindow, couldn't receive any mouse event,<br/> this cause wx.ListCtrl and wx.PopupWindow have no response while user generate any mouse action.<br/></p> <p>If wx.Dialog is opened by calling Show(),<br/>the above situation won't happen, wx.PopupWindow and wx.ListCtrl work correctly.<br/></p> <p>However, the above situation won't happen in windows version of wxPython 2.8.x even if we show wx.Dialog by calling ShowModal(),<br/>it happen in linux only.<br/></p> <p>Any suggestion?</p> <p>Thanks.</p> <p>Here is my source code.<br/> It may be too long but is easy enough to test the above situation (just copy and paste).<br/></p> <pre><code>#!/usr/bin/env python # -*- coding: utf-8 -*- import sys import wx class TestPopupWindow(wx.PopupWindow): # modify here to change different Widget def __init__(self, *args, **kwargs): super(TestPopupWindow, self).__init__(*args, **kwargs) self.SetSize((200, 200)) self.testButton = wx.Button(self, label='Test') self.testButton.Bind(wx.EVT_BUTTON, self.__onEvtButton, self.testButton) self.Show() def __onEvtButton(self, event): event.Skip() print 'PopupWindow: test button pushed!' self.Hide() class TestDialog(wx.Dialog): def __init__(self, *args, **kwargs): wx.Dialog.__init__(self, *args, **kwargs) panel = wx.Panel(self) panel.SetAutoLayout(True) sizer = wx.BoxSizer(wx.VERTICAL) sizer.Fit(panel) sizer.SetSizeHints(panel) panel.SetSizer(sizer) for i in xrange(2): ctrl = wx.TextCtrl(panel) sizer.Add(ctrl, 0, wx.ADJUST_MINSIZE|wx.EXPAND, 0) for i in xrange(2): ctrl = wx.ComboBox(panel) sizer.Add(ctrl, 0, wx.ADJUST_MINSIZE|wx.EXPAND, 0) self.openPopupWindowButton = wx.Button(panel, label='Open PopupWindow') sizer.Add(self.openPopupWindowButton, 0, 0, 0) standardDialogButtonSizer = wx.StdDialogButtonSizer() self.standardDialogButtonSizerOK = wx.Button(panel, wx.ID_OK) standardDialogButtonSizer.AddButton(self.standardDialogButtonSizerOK) self.standardDialogButtonSizerCancel = wx.Button(panel, wx.ID_CANCEL) standardDialogButtonSizer.AddButton(self.standardDialogButtonSizerCancel) standardDialogButtonSizer.Realize() sizer.Add(standardDialogButtonSizer, 0, wx.EXPAND, 0) panel.Layout() # event binding self.openPopupWindowButton.Bind(wx.EVT_BUTTON, self.__onEvtButtonOpenPopupWindow, self.openPopupWindowButton) self.popupWindow = None # event handler def __onEvtButtonOpenPopupWindow(self, event): event.Skip() if self.popupWindow is not None: self.popupWindow.Close() self.popupWindow = TestPopupWindow(self) class TestFrame(wx.Frame): def __init__(self, *args, **kwargs): wx.Frame.__init__(self, *args, **kwargs) panel = wx.Panel(self) panel.SetAutoLayout(True) sizer = wx.BoxSizer(wx.VERTICAL) sizer.Fit(panel) sizer.SetSizeHints(panel) panel.SetSizer(sizer) self.openButton = wx.Button(panel, label='Open Dialog') sizer.Add(self.openButton, 0, 0, 0) self.openPopupWindowButton = wx.Button(panel, label='Open PopupWindow') sizer.Add(self.openPopupWindowButton, 0, 0, 0) panel.Layout() # event binding self.openButton.Bind(wx.EVT_BUTTON, self.__onEvtButtonOpen, self.openButton) self.openPopupWindowButton.Bind(wx.EVT_BUTTON, self.__onEvtButtonOpenPopupWindow, self.openPopupWindowButton) self.Show() self.popupWindow = None # event handler def __onEvtButtonOpenPopupWindow(self, event): event.Skip() if self.popupWindow is not None: self.popupWindow.Close() self.popupWindow = TestPopupWindow(self) def __onEvtButtonOpen(self, event): event.Skip() dialog = TestDialog(self, title='TestDialog') result = dialog.ShowModal() if result == wx.ID_OK: print &gt;&gt;sys.stderr, 'OK!' else: print &gt;&gt;sys.stderr, 'Cancel!' def main(argv=sys.argv[:]): app = wx.PySimpleApp() frame = TestFrame(None, title='TestFrame', style=wx.TAB_TRAVERSAL|wx.DEFAULT_FRAME_STYLE) app.SetTopWindow(frame) app.MainLoop() return 0 if __name__ == '__main__': sys.exit(main()) </code></pre>

    1. COMaybe you can add some code so people can try it out and see if it's specific to your system or not? You could also try asking this on the wxPython mailing list.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
