Re: [Development] How to get winid from qprocess id for QProcess

[Jason H]

I think this question is better suited to the qt-interest mailing list.

 

It has been decades since I did Win32 programming, but I would assume that you could ask Windows to find the window for you and give you the HWND. I don't think you can map from process to HWND, you'd have to map HWND to process?

 

But my days of programming Win32 are long over. Thank you, Qt!

Subject: [Development] How to get winid from qprocess id for QProcess

hi friend

 

I am running an external app, which I want to fit onto my QScrollArea, for this I am writing code like this.

 

// launch weasis
QProcess *process = new QProcess();
process->start("./viewer-win32.exe");
if (process->waitForFinished())
{
return;
}

 

QWindow *window = QWindow::fromWinId(211812356);
window->setFlags(Qt::FramelessWindowHint);
_patient_gui->scrollArea_1->setWidget(QWidget::createWindowContainer(window));

 

But how can I get the wind id? it is hard coded here, is there any way to get the id from process id.

 

any help is highly appreciated.
