Hi guys, i need some help.
I'm trying to do some project in order to learn Qt (thats the best way of learning i think) .
Anyway, I want to embed an external process to a widget, specifically the mplayer process.
so I m creating the process mplayer and i want it to be displayed into my widget, so i can
have control over it.
Thank you guys in advance,
btw, this is my firts post
good job for the forum
With mplayer it is fairly easy. Use a -wid parameter with mplayer and as an argument specify window id (returned by QWidget::winId()) of the widget you want to embed the player in.
what incase of a generic application? eg java applet or something of that sort?
This comes down to the Xlib layer then, I guess. There is a Qt Solution which does that.Quote:

Honestly, i didn't know about this class till this thread :p
I went to the link you gave and had a look through the docs for the same...
Thanks
Nupul.
Doesn't it only allow embedding applications which allow that by allowing to specify a window ID to open into?
yes.Quote:

Thank you guys for your replies.Quote:

I knew about QX11EmbedContainer and had a look before but i got a bit confused, thats why i posted here, i guess i am just a newbie :)
I ll try this thing out.
thanks again
No, that's the problem. Not any app, just the ones which use XEmbed (which is of course in XLib layer).Quote:

Qt is cross-platform isn't it?;)
Let me open up this thread again, because I am having a problem with it. I can get MPlayer embedded using its -wid parameter. But I am unable to embed any window by passing the WindowID to QX11EmbedContainer::embedClient. The old Qt3 solution sample code doesn't work (after porting to qt4 of course), and neither does the QDevBlog sample for XEmbed here <http://blogs.qtdeveloper.net/archives/2005/08/10/playing-around-with-xembed/>. This is very frustrating because I know it works in Qt3, and worked long enough in Qt4 for the QDevBlog to get a screenshot of it.
I have logged this as a bug with Trolltech, but I am wondering if anyone else has seen this, and whether it's a new bug. Please use the QDevBlog sample code for discussion.
Thanks...
The QDevBlog example worked for me (SUSE 10, Qt 4.1.4) embedding Konquerer. I used xwininfo to find the window id.
Doing a bit of playing around, I see that it works under 4.1.4, but not under 4.2.0-rc1. After logging four bugs in one day, I'm starting to think the "release candidate" is the wrong term to use...
Sorry for reopening... but I find this to be a good question. How does one do this under Windows? I assume QX11EmbedWidget will obviously only work under X11.Quote:

I'm also wondering this - is it possible to embed an external application under Windows? Or only for Linux?Quote:

Yeah, but I mean the wid from the external application, not my own widget.
Just run xterm with "-into X" where X is the winId returned by the window you wish to embed xterm into.
I tried exactly this, but xterm opens in a separate window.

Here's some code:
edit2:Quote:
Shell::Shell(QWidget *parent)
: QDockWidget(parent)
{
setObjectName("Shell");
setWindowTitle("Shell");
QWidget *widget=new QWidget(this);
setWidget(widget);
process=new QProcess(this);
process->start("xterm -into "+QString((int)widget->winId()));
widget->show();
}
I made a screenshot for you, so you can understand what I am trying to achieve:
It fails because your QString "cast" fails. Look that there is no QString constructor taking a sole int as a parameter.
Oh hehe, sorry fur bugging you. Anyways, isn't there a solution to implement any foreign window?
As far as I know, there is no such solution.
