Re^2: wxPreviewFrame error on closing

Hi Anon,

Well, I've followed through some of your links. The first thing I noticed was that wxPreviewFrame::OnCloseWindow isn't wrapped for wxPerl (or at least it doesn't seem to be. A fact not noted in the documentation. So I created my own version:

sub on_click_richtext_preview_close {

    my($self,$event) = @_;

    $self->Destroy;

}
[download]

And called it with:


    Wx::Event::EVT_CLOSE( $frame , \&on_click_richtext_preview_close )
+;
[download]

just before the initialise. It Seems to work, but the main frame, to which it is returned, is disabled (in my version of the code). Can I just enable it, or is that too easy?

Regards

Steve

The first thing I noticed was that wxPreviewFrame::OnCloseWindow isn't wrapped for wxPerl It doesn't make sense to wrap it http://svn.wxwidgets.org/svn/wx/wxWidgets/trunk/src/common/prntbase.cpp IMPLEMENT_CLASS(wxPreviewFrame, wxFrame) BEGIN_EVENT_TABLE(wxPreviewFrame, wxFrame) EVT_CLOSE(wxPreviewFrame::OnCloseWindow) END_EVENT_TABLE() ... void wxPreviewFrame::OnCloseWindow(wxCloseEvent& WXUNUSED(event)) { if (m_windowDisabler) delete m_windowDisabler; // Need to delete the printout and the print preview wxPrintout printout = m_printPreview->GetPrintout(); if (printout) { delete printout; m_printPreview->SetPrintout(NULL); m_printPreview->SetCanvas(NULL); m_printPreview->SetFrame(NULL); } delete m_printPreview; Destroy(); } [download] It Seems to work, but the main frame, to which it is returned, is disabled (in my version of the code). Can I just enable it, or is that too easy?* You could do that, but as you can see above the wxWindowDisabler is deleted, which re-enables the previously disabled windows, so it should work already :)	[reply] [d/l]

Hi Anon, Well then, is it possible that one of the wrappings (maybe the one I did on RichTextPrintout) is not passing the event on to wxPrintout or whatever it's equivalent is? Because when I manually capture EVT_CLOSE and handle it, it's as near as I can get to the correct processing. Alternatively, I could mimic the above c-processing, but I'd need a couple of hints: How to access `windowDisabler` since I don't know its Hash-name or address-pointer within the parent object. I'm not sure what the difference between `delete` and `Destroy()` is. I guess `delete` is remove an element from a Hash and then `Destroy()` is remove the object. In Perl, wouldn't the `delete`s be automatic if you just `Destroy()`ed the object? So in that case all I have to do is to `delete`/`Destroy()` the windowDisabler as well.

..is not passing the event on to wxPrintout or whatever it's equivalent is? Not likely How to access ... Probably `$self->SUPER::OnCloseWindow($event)` or add a `void DeleteWindowDisabler (){ if (m_windowDisabler) delete m_windowDisabler; }` [download] then call `$self->DeleteWindowDisabler();` but like I said, it should work already :) I'm not sure what the difference between delete is delete (or undef), Destroy is the destructor, it gets called after the object goes out of scope or is deleted	[reply] [d/l] [select]
