[QTest][GUI] Is possible to show and set window's background?

Hi!

I found QTest useful for DirectX compute shader's output test, but for that purpose I need a fully initialized windows.

I tried in several ways but it seems like I'm unable to create a simple QMainWindow.

Main.CPP

#include "DirectX11TestShader.h"

QTEST_MAIN(DirectX11TestShader)

TestScreen.H

class TestScreen : public QMainWindow
{
    Q_OBJECT
public:
};

DirectX11TestShader.H

class DirectX11TestShader: public QObject
{
    Q_OBJECT
private slots:
    void initTestCase();
private:
    TestScreen mScreen;
};

DirectX11TestShader.CPP

#include "DirectX11TestShader.h"

void DirectX11TestShader::initTestCase()
{
    mScreen.show();
    mScreen.setStyleSheet("background-color: black;");
}

This windows is always shown white, and my test always throw DXGI_ERROR_DEVICE_REMOVED / DXGI_ERROR_DEVICE_HUNG. The code is working ok in normal workflow only in QTest is failing.

I want to guarantee the window creation, what can I do?

Hi,

Did you try to use qWaitForWindowExposed ?
