Problems using QtWinExtras on Windows XP

[cijic]

Hello. Can anyone tell how to run program with code like this on Windows XP, to ignore futures for Win7 if it can't be run? App compiles, but crashes.

@
#include "mainwindow.h"
#include "ui_mainwindow.h"
#include <QtWinExtras>

MainWindow::MainWindow(QWidget *parent) :
QMainWindow(parent),
ui(new Ui::MainWindow)
{
ui->setupUi(this);

QWinThumbnailToolBar *m_tt = new QWinThumbnailToolBar(this);
m_tt->setWindow(windowHandle());

}

MainWindow::~MainWindow()
{
delete ui;
}

Hi,

Maybe with "QSysInfo":http://qt-project.org/doc/qt-5/qsysinfo.html

Hope it helps

No. It crashes anyway.

Hi,

Thumbnail toolbars require Windows 7 or higher.

Your program crashes because it tries to call functions in Windows system DLLs that don't exist. Use QSysInfo::WindowsVersion to check the version. If it's older than Windows 7, do not create QWinThumbnailToolBar.
