Start external application. Lost focus.

[qomg]

Hi I run VLC as a process and everything ok only my application loses focus and I can not kill it by pressing the button, because first I have to click back to the application window. Anyone know how to restore the focus?

@#ifndef STARTEXTERNALAPPLICATION_H
#define STARTEXTERNALAPPLICATION_H

#include <QObject>
#include <QProcess>

class StartExternalApplication : public QObject
{
Q_OBJECT

QProcess *myProcess;

public:
explicit StartExternalApplication(QObject *parent = 0);

public slots:
void start();
void kill();
};

#endif // STARTEXTERNALAPPLICATION_H@

@#include "startexternalapplication.h"
#include <QApplication>

StartExternalApplication::StartExternalApplication(QObject *parent) :
QObject(parent)
{
myProcess = new QProcess( qApp );
}

void StartExternalApplication::start() {
QString program = "C://Program Files//VideoLAN//VLC//vlc.exe";
QStringList arguments;
arguments << "E:\Photos & Videos\2014\CAM00065.mp4" << "--play-and-exit"; // << "-f";
myProcess->start( program, arguments );
}

void StartExternalApplication::kill() {
myProcess->kill();
}@

@#include <QApplication>
#include <QQmlApplicationEngine>
#include <QtQml>
#include "startexternalapplication.h"

int main(int argc, char *argv[])
{
qmlRegisterType<StartExternalApplication>("StartExternalApplication", 1, 0, "StartExternalApplication");

QApplication app(argc, argv);

QQmlApplicationEngine engine;
engine.load(QUrl(QStringLiteral("qrc:///main.qml")));

return app.exec();

}

@import QtQuick 2.2
import QtQuick.Controls 1.1
import StartExternalApplication 1.0

ApplicationWindow {
visible: true
width: 640
height: 480
title: qsTr("StartExternalApplication")

StartExternalApplication {
    id: app
}

Rectangle {
    width: parent.width /2
    height: parent.height
    color: "yellow"
    Text {
        text: qsTr("Click to open E:\\Photos & Videos\\2014\\CAM00065.mp4 in VLC")
        anchors.centerIn: parent
    }
    MouseArea {
        anchors.fill: parent
        onClicked: app.start()
    }
}

Rectangle {
    x: parent.width /2
    width: parent.width /2
    height: parent.height
    color: "blue"
    Text {
        text: qsTr("Press Space to kill process")
        anchors.centerIn: parent
    }
    Item {
        anchors.fill: parent
        focus: true
        Keys.onPressed: {
            if (event.key === Qt.Key_Space)
                app.kill()
        }
    }
}

}

Hi, you could try waiting for VLC to finish and then take back the keyboard focus, for example, after
myProcess->start( program, arguments ); add
myProcess->waitForFinished(-1);
and then get keyboard focus back to your app by calling activateWindow().

After closing VLC focus reintroduced. I would like to focus was restored immediately after the start of the process.
