If you are using the main C++ distribution of wxWidgets, Feel free to ask any question related to wxWidgets development here. This means questions regarding to C++ and wxWidgets, not compile problems.

This doesn't seem to work on i686-w64-mingw32. Just me?
Code: Select all
// wxWidgets "Hello World" Program
// For compilers that support precompilation, includes "wx/wx.h".
#include <wx/wxprec.h>
#ifndef WX_PRECOMP
#include <wx/wx.h>
#endif
class MyApp : public wxApp
{
public:
virtual bool OnInit();
};
class MyFrame : public wxFrame
{
public:
MyFrame();
private:
void OnHello(wxCommandEvent& event);
void OnExit(wxCommandEvent& event);
void OnAbout(wxCommandEvent& event);
void OnClose(wxCloseEvent& event); // Added
};
enum
{
ID_Hello = 1,
ID_Close // Added
};
wxIMPLEMENT_APP(MyApp);
bool MyApp::OnInit()
{
MyFrame *frame = new MyFrame();
frame->Show(true);
return true;
}
MyFrame::MyFrame()
: wxFrame(NULL, wxID_ANY, "Hello World")
{
wxMenu *menuFile = new wxMenu;
menuFile->Append(ID_Hello, "&Hello...\tCtrl-H",
"Help string shown in status bar for this menu item");
menuFile->AppendSeparator();
menuFile->Append(wxID_EXIT);
wxMenu *menuHelp = new wxMenu;
menuHelp->Append(wxID_ABOUT);
wxMenuBar *menuBar = new wxMenuBar;
menuBar->Append(menuFile, "&File");
menuBar->Append(menuHelp, "&Help");
SetMenuBar( menuBar );
CreateStatusBar();
SetStatusText("Welcome to wxWidgets!");
Bind(wxEVT_MENU, &MyFrame::OnHello, this, ID_Hello);
Bind(wxEVT_MENU, &MyFrame::OnAbout, this, wxID_ABOUT);
Bind(wxEVT_MENU, &MyFrame::OnExit, this, wxID_EXIT);
Bind(wxEVT_CLOSE_WINDOW, &MyFrame::OnClose, this, ID_Close); // Added
}
void MyFrame::OnClose(wxCloseEvent& event) // Added
{ // Added
wxLogMessage("[DOES THIS CALLED?]"); // Added
} // Added
void MyFrame::OnExit(wxCommandEvent& event)
{
wxLogMessage("Now exits.");
Close(true);
}
void MyFrame::OnAbout(wxCommandEvent& event)
{
wxMessageBox("This is a wxWidgets Hello World example",
"About Hello World", wxOK | wxICON_INFORMATION);
}
void MyFrame::OnHello(wxCommandEvent& event)
{
wxLogMessage("Hello world from wxWidgets!");

Which part of the wx code were you expecting to send a wxCloseEvent with an id set to your `ID_Close` value?
p.s. Please explain in a few words what "doesn't work" means to you.

Oh, I was wondering if Bind () failed because the application's close button just closes the window without a dialog. But the problem of ID.
