1. wxMDIChildFrame problem

#2556

Posted by: 2003-08-25 22:36:08

When i click an event to open a new window, but, the program crashed, prompt me "Bugs report etc..".

then, the program will be force closing by window.

My testing evironment is on Window XP

void MyFrame::OnNewWindow(wxCommandEvent & WXUNUSED(event)) {

    MyChildWindow *subframe = new appChildWindow(frame, _T("Test New Window"),
                                    wxPoint(-1, -1), wxSize(-1, -1),
                                    wxDEFAULT_FRAME_STYLE);

    subframe->SetTitle("A");
    subframe->Show(TRUE);
}

could somebody tell me what happen?

Thank you.

Looks like the problem is inside appChildWindow constructor. Can you post its code?

Now that's great :) I thought it was clear that the definition of the constructor is needed, not the declaration. I want to see, what does this constructor do.

Could you please dump the body of the constructor, line by line! Ain't it so hard?
Like this:


appChildWindow::appChildWindow(/* ...... */) :
    wxMDIChildFrame(/* ..... */)
{
    // And so on
}

Most likely, the error is inside appChildWindow, but I'm not a magician to guess where exactly.

By the way - is MyFrame derived from wxMDIParentFrame?

Hi, is that this one?



appChildWindow::appChildWindow(wxMDIParentFrame *parent, const wxString& title,
                 const wxPoint& pos, const wxSize& size,
                 const long style)
       : wxMDIChildFrame(parent, -1, title, pos, size,
                         style | wxNO_FULL_REPAINT_ON_RESIZE){
    my_children.Append(this);

    
    SetSizeHints(100, 100);
}

appChildWindow::~appChildWindow(){
    my_children.DeleteObject(this);
}

Meow~

Yes, that's it, great :)
But, unfortunately, the problem is still isn't clear :( Let's dig furhter.
Do I understand it right, that my_children is a wxList or wxObjArray object and it is global?

my_children is wxList, global variable

Next guess. Is 'frame' variable properly initialized before calling MyFrame::OnNewFrame? And, by the way, what is the class MyFrame derives from and what is the type of 'frame'? Is 'frame' just another name for 'this'?
