[solved] Crash when creating QQuickView from QTimer event
-
I try to create a QQuickView in a function that is triggered by a timer, but it triggers an exception. (The inferior stopped because it triggered an exception. ...read access violation...) If I create a QQuickView manually before the timer triggers the function that creates a QQuickView, the program will not crash.
Anybody know why this happens? What am I doing wrong?A bit of an bad explanation, but i hope the code explais it better.
app.cpp
@
#include "app.h"
#include <QTimer>App::App( int argc, char* argv[] )
: QGuiApplication( argc, argv )
, view( NULL )
{
// If the line below is included the program works
//QQuickView* tempView = new QQuickView();QTimer::singleShot( 5000, this, SLOT( createView() ) );}
void App::createView()
{
view = new QQuickView();
}
@app.h
@
#ifndef APP_H
#define APP_H#include <QGuiApplication>
#include <QQuickView>class App : public QGuiApplication
{
Q_OBJECT
public:
App( int, char** );public slots:
void createView();private:
QQuickView *view;
};#endif // APP_H
@main.cpp
@
#include "app.h"int main(int argc, char *argv[])
{
App app(argc, argv);
return app.exec();
}

Hi,
I can't tell immediately what the problem is, but why are you subclassing QGuiApplication?
