launching external program(qt) inside another qt program

[babu198649]

hi
how to launch a external qt program (which has seperate main) inside another qt application.

example:
executing the examples of qt demo in the same window instead of launching it outside the qtdemo.

[jacek]

Use QProcess.

[babu198649]

QProcess will launch programs outside the mainprogram.

i.e
if a program contains a MainWindow then the launched program should reside inside the mainwindow

[jacek]

You can try QxxxEmbedWidget with xxx being either WS or X11 depending on the OS.

thank u very much jacek
how to find the Wid(window id ) of a program which has not yet launched (or not yet displayed on the screen). is it possible with QProcess

[jacek]

You can't get the window id of a window that doesn't exist.

[babu198649]

is it possible to embed a non qt application inside qt application by just knowing the path of the application( qt should invoke the application ).

It's quite hard to do that in general case, because there's no reliable way to get the window id, but some applications (for example mplayer) have special functionality that make embedding them easier.
