Obtaining Windows Handle for Child Process

[GTBuilder]

Is there any way to get the windows handle for a child process besides waiting for the process to start and using something like the following to push the parent down to ensure the child is on top:

hParent = winId();
.
.
process.start( "cmd.exe", args);
SetWindowPos( hParent, HWND_BOTTOM, x, y, cx, cy, SWP_NOSIZE); 
hChild = GetForeGroundWindow();

hParent = winId();
.
.
process.start( "cmd.exe", args);
SetWindowPos( hParent, HWND_BOTTOM, x, y, cx, cy, SWP_NOSIZE); 
hChild = GetForeGroundWindow();

To copy to clipboard, switch view to plain text mode

I'm sure you can obtain it through QProcess::pid().

Wysota, thanks for pointing me in the right direction. Unfortunately I'm now stuck with how to extract the handle from the PROCESS_INFORMATION structure that Q_PID points to.

The following code:

Q_PID pid;
 
hChild = pid->hProcess;

Q_PID pid;

hChild = pid->hProcess;

To copy to clipboard, switch view to plain text mode 

gives a compiler error:

invalid conversion from 'void*' to 'HWND_*'

It's not a window handle but a process handle.

OK, now I'm back to square one. Q_PID points to PROCESS_INFORMATION which doesn't contain the HWND I'm looking for. I was hoping there was a better way then using
GetForegroundWindow(). Or am I missing something fundamental here. I've only just started to digging into WinAPI.

[wysota]

It doesn't have to contain the handle. There probably is some WinAPI call that asks for window handles of a particular process.
