wxWidgets Invoke?

[BluePhaz]

Guten Morgen,

ich habe ein wxWidgets App mit 2 Threads geschrieben. Der eine Thread macht einen Frame mit einem StaticText auf und der andere Thread soll diesen Text verändern. Leider zeigt mir das Programm nach dem zweiten ThreadStart nur noch "Keine Rückmeldung" an. Brauche ich eventuell wie auch in C# soetwas wie Invoke? Wenn ja gibt es verschiedene Möglichkeiten?

Hier mein Quellcode:

App.h:

#ifndef __App_
#define __App_

#include "StaticTextFrame.h"

class App : public wxApp
{
	public:
		StaticTextFrame* StaticTextFrameX;

	public:
		virtual bool OnInit();
};

DECLARE_APP(App);

#endif

App.cpp:

#include <wx/wx.h>
#include "App.h"
#include "MainFrame.h"

IMPLEMENT_APP(App);

bool App::OnInit()
{
	MainFrame* MainFrameX = new MainFrame(0L);
	MainFrameX->SetIcon(wxICON(MainIcon));
	MainFrameX->Show();

	return true;
}

EditStaticTextThread.h:

#include <wx/wx.h>
#include "App.h"
#include "StaticTextFrame.h"

class EditStaticTextThread : public wxThread
{
	public:
		EditStaticTextThread() : wxThread(wxTHREAD_JOINABLE)
		{
		}

		void* Entry()
		{
			StaticTextFrame* StaticTextFrameX = wxGetApp().StaticTextFrameX;

			StaticTextFrameX->SetLabel("Hello World!");

			return NULL;
		}
};

Wieso stürzt das Programm ab?
