@karti-gesar
As per this http://doc.qt.io/qt-5/qquickview.html#QQuickView-1
You should delete a engine before you delete view ?

mrjj

hmm
// create
QQuickView * myvar= new QQuickView();
//destroy
delete myvar;

//
myProcess->start(".exe"); ???

myProcess->start("/full/path/to/thefile.exe");

Please see
http://stackoverflow.com/questions/2622864/start-a-process-using-qprocess
Also, note how to pass parameters and that " " spaces must be handled on windows.

@mrjj working but issue that background qquickview still running

karti gesar

when i put like this

void fn()
{
view.destroy();
}
this works fine background operation also deleteing..
but how to call process ..

mrjj

"but how to call process .."

QProcess *process = new QProcess(this);
QString program = "explorer.exe"; // the program. for some programs. FULL PATH must be used
QString folder = "C:\"; // parameters
process->start(program, QStringList() << folder);

// Note
at some point u need to do
delete process ;

if i used that view is not destroying

use QQuickview to call a qml.....have a image in a qml ....if u press any key in qml i.e.,in image ..that view should be destroyed...you want to display a dialog in qt with a button..for that qprocess is used to call...dialog .exe

suppose when a dialog is opened..if you clicked the button again you want to call the qml i.e.,that image in qml..like that viceversa
