Problem with QTabWidget and QX11EmbedWidget, keyboard stops working

J_ocaetano

Hi, in my applicatin I have two widgets constructed separately. Using QX11EmbedContainer + QProcess I can execute the second widget inside the first, and it works fine.

The problem is when I stop the second when it has the focus and I change the actual tab(First widget has a QtabWidget), the keyboard simply stop working.

I have no idea what might be happening.

This is my code:

First Widget:

@#include "mainwindow.h"

MainWindow::MainWindow(QWidget *parent) : QWidget(parent), ui(new Ui::Prototype_tab)
{
showMaximized();

ui->setupUi(this);

connect(ui->startButton, SIGNAL(pressed()), this, SLOT(startPrototype()));
connect(ui->stopButton, SIGNAL(pressed()), this, SLOT(stopPrototype()));

}

MainWindow::~MainWindow()
{
delete ui;
}

void MainWindow::startPrototype() {
ui->startButton->setEnabled(false);
ui->label_screenshot->hide();
container = new QX11EmbedContainer(ui->tabWidget);
container->setSizePolicy(QSizePolicy::Expanding, QSizePolicy::Expanding);
container->setMinimumSize(600, 600);
ui->gridLayout->addWidget(container,1,1);
myProcess = new QProcess(container);
myProcess->setWorkingDirectory("../../simpleX11Embed/build");
myProcess->start("./simpleX11Embed", QStringList() << "-into" << QString().setNum(container->winId()));
ui->stopButton->setEnabled(true);
connect(myProcess, SIGNAL(finished(int)), this, SLOT(enableStartButton()));
}

void MainWindow::stopPrototype() {
myProcess->close();
}

void MainWindow::enableStartButton() {
container->close();
ui->label_screenshot->show();
ui->stopButton->setEnabled(false);
ui->startButton->setEnabled(true);
}

int main(int argc, char *argv[])
{
QApplication a(argc, argv);
MainWindow w;
w.show();

return a.exec&#40;&#41;;

}@

Second Widget :

@#include "simpleX11Embed.h"

MainWindow::MainWindow(QWidget *parent) : QX11EmbedWidget(parent) {

QTextEdit *textBrowser = new QTextEdit();
textBrowser->setFocusPolicy(Qt::StrongFocus);
textBrowser->setSizePolicy(QSizePolicy::Expanding, QSizePolicy::Expanding);

QVBoxLayout *widlayout = new QVBoxLayout(this);
widlayout->addWidget(textBrowser);

}

int main(int argc, char *argv[]){
QApplication app(argc, argv);

if(app.arguments().count() > 2)
    if (app.arguments()[1] == "-into") {
        QString windowId(app.arguments()[2]);
        MainWindow window;
        window.embedInto(windowId.toULong());
        window.show();
        return app.exec();
     }

MainWindow w;
w.show();
return app.exec();

No prompt answer, but I'd suggest to try debugging
