为什么 wxCrafter Hello World 程序不起作用？ [C++，wxWidgets]

Question

I followed the wxCrafter Hello World tutorial: https://wiki.codelite.org/pmwiki.php/Main/WxCrafterHelloWorld

Building process shows no errors, however no dialog shows up when I click "Build->Run" in CodeLite 13, for some reason nothing happens :/

main.cpp:

#include <wx/app.h>
#include <wx/event.h>
#include "MainDialog.h"
#include <wx/image.h>


// Define the MainApp
class MainApp : public wxApp
{
public:
    MainApp() {}
    virtual ~MainApp() {}

    virtual bool OnInit() {
        // Add the common image handlers
        wxImage::AddHandler( new wxPNGHandler );
        wxImage::AddHandler( new wxJPEGHandler );

        MainDialog mainDialog(NULL);
        mainDialog.ShowModal();
        return false;
    }
};

DECLARE_APP(MainApp)
IMPLEMENT_APP(MainApp)

MainDialog.h:

#ifndef MAINDIALOG_H
#define MAINDIALOG_H
#include "wxcrafter.h"

class MainDialog : public MainDialogBaseClass
{
public:
    MainDialog(wxWindow* parent);
    virtual ~MainDialog();
protected:
    virtual void OnButtonokButtonClicked(wxCommandEvent& event);
};
#endif // MAINDIALOG_H

MainDialog.cpp:

#include "MainDialog.h"
#include <wx/msgdlg.h> 

MainDialog::MainDialog(wxWindow* parent)
    : MainDialogBaseClass(parent)
{
}

MainDialog::~MainDialog()
{
}

void MainDialog::OnButtonokButtonClicked(wxCommandEvent& event)
{
    ::wxMessageBox(_("Hello World"));
}

Answer 1

Something is wrong with either the C::L installation or the wxCrafter plugin.

If you did follow the referenced tutorial, it should create a wxButton object as a member of the dialog and bind the event handler to it.

Can you compile and run the minimal sample from the wxWidgets install?
