example using Qwindow

Hi,

i have written a sample program using Qwindow.
i would like to set some color or add some image to QWindow, but as soon as i run the program the window is opening with background color of other below windows , in my case i m opening from qtcreator,so the window is opening with qtcrator background.


hellotest.cpp

Code:

---

#include "hellotest.h"
 
HelloTest :: HelloTest(QWindow *parent):
  QWindow(parent)
 
{
     QWidget *cont = new QWidget;
     QVBoxLayout *vl = new QVBoxLayout;
    qDebug() << "in hello test";
    //QWidget *window = new QWidget(parent);
    //QProcess *process = new QProcess(this);
    QStringList args;
    //args<<"-style"<<"fusion";
    //process->start("../../sample-build-Qt5_1Alpha-Debug/sample");//,args);
 
    QWidget *window = new QWidget ;//::createWindowContainer(this,0,0);
    window -> resize(500,500);
    window ->setPalette(QPalette(QColor(255,0,0,255)));
    //setIcon(QIcon("/home/ramu/Pictures/screen.png"));
    //window -> setPalette(QPalette(QColor(0,255,0,255)));
    //window -> setAutoFillBackground(true);
    cont -> setLayout(vl);
    vl -> addWidget(window);
}
 
HelloTest::~HelloTest()
{
 
}

You are creating widgets but not showing them.

Hi anda_skoa
i am in the process of converting my Qt4 related code to Qt5 in below thread.

can you please look at it and guide me .

thanks

Ah.

I think in both applications you would just use normal QWidgets.
In the one that is the container you create a window using fromWinId() and embed that into your widget using createWindowContainer.

Haven't tried that myself yet, but that is how I would approach it.

Hi anda_skoa,

I have update with the new code.

if possible have a look and let me know if you have any points.
