How to resize XEmbed in Qt5 with window size change

devqore

Hi,
I'm trying to resize external application which is attached to application using QWidget::createWindowContainer for simplicity in example xterm is used:

#include <QApplication>
#include <QWidget>
#include <QVBoxLayout>
#include <QWindow>
#include <QProcess>

int main(int argc, char *argv[])
{
    QApplication app(argc, argv);
    QWidget widget;
    QWindow window;
    QWidget *container = QWidget::createWindowContainer(&window, &widget);
    QVBoxLayout layout;
    QProcess process;
    QStringList arguments;
    
    layout.addWidget(container);
    widget.setLayout(&layout);
    widget.show();
    arguments << "-into" << QString::number(container->winId());  // also doesn't work properly with window.winId()
    process.start("xterm", arguments);

    return app.exec();
}

And in this example xterm is not resized when main widget is resized, following example works in Qt4 with QX11EmbedContainer:

#include <QApplication>
#include <QWidget>
#include <QX11EmbedContainer>
#include <QVBoxLayout>
#include <QProcess>

int main(int argc, char *argv[])
{
    QApplication app(argc, argv);
    QWidget widget;
    QX11EmbedContainer container(&widget);
    QVBoxLayout layout;
    QProcess process;
    QStringList arguments;

    layout.addWidget(&container);
    widget.setLayout(&layout);
    widget.show();
    arguments << "-into" << QString::number(container.winId());
    process.start("xterm", arguments);

    return app.exec();
}

Does anybody have idea how I can achieve such effect in Qt5 like in Qt4 with QX11EmbedContainer? Any tips will be very helpful.

It looks that solution in GTK is quite simple, it's sad that Qt5 hasn't nothing to offer like it was in Qt4 with QX11EmbedContainer...

Simple example in GTK3 using python:

import gi
gi.require_version("Gtk", "3.0")
from gi.repository import Gtk
from subprocess import Popen

window = Gtk.Window(title="Xterm embed")
socket = Gtk.Socket()
window.add(socket)
sock_id = str(socket.get_id())

# sendEvents required according to xterm documentation
cmd = ["xterm", '-xrm', "xterm*.allowSendEvents: true", "-into", sock_id]

Popen(cmd)
socket.show()
window.show()
window.connect("destroy", Gtk.main_quit)
Gtk.main()

Hi
Did you try

@mrjj I didn't recieve any message about your response, and I saw it when I tried to find solution of this problem once again after while :P

I already saw this repository but I didn't used because I would like to find solution without compiling additional plugins also repository looks like not developed anymore.
