QMainWindow modal from non-qt window?

Hello,

I am trying to make a test QT for the purpose of a Photoshop plugin. For now, i am able to display a QT window (QMainWindow) when the Photoshop plugin is started, but i am having an issue: since i cant tell the QMainWindow who is it's owner, the QMainWindow is not modal. So my question is, is there any way to tell my QMainWindow that another (Which i HAVE the hwnd handle) is it's parent?

I will probably have the same issue when compiling for mac, but i guess if there is a solution, it will solve both :)

Thanks,
Pierre.

Thanks to this post: http://www.qtcentre.org/forum/f-qt-p...nter-3713.html
I found it typing different keywords in search function.

Here is what i did if someone else needs (Photoshop HWND is in "psHwnd"):

Code:

---

// This is my QT window:
CWndMainImpl cMainWin;
// This comes from the W32 API:
SetParent((HWND)&cMainWin, psHwnd);
cMainWin.show();
app.connect( &app, SIGNAL(lastWindowClosed()), &app, SLOT(quit()) );
app.exec();

---

So, if what i'm doing is good, it would mean that the (HWND) operator of QMainWindow has been overloaded to return a windows handle... Is that it?

And it seems ok :)
Thanks anyway ^^
Pierre.

[EDIT] NOT SOLVED:
After doing this, the window was modal to the "current picture" window in photoshop... But after more testing, when i click any photoshop area, my QT window is finally not modal...
What am i doing wrong?

Finally solved, it appears that there is no cast overload defined for (HWND) operator on QObject. So the solution is to get the ID of the window, see code following.

Code:

---

// This is my QT window:
CWndMainImpl cMainWin;
// This comes from the W32 API:
SetParent((HWND)cMainWin.winId(), psHwnd);
cMainWin.show();
app.connect( &app, SIGNAL(lastWindowClosed()), &app, SLOT(quit()) );
app.exec();

Sorry that I reopen this thread again.
I try this with Photoshop 6.0, and my QMainWindow can show up, and "seem to be"
modal. I can't access any one of Photoshop's toolboxes and tool bar, and the menu "looks" gray. But when I move my mouse pointer over Photoshop menu, the menu becomes black and accessible. How to make Photoshop to be fully blocked until my QMainWindow is closed?
Thanks a lot for any hints.
