Window widget not moving with move()

[Xena_o]

hello

i am trying to move a window with move() inside a MDIarea but that is not working, here is the code :

wCon = new myWindow(this);
wCon->setAttribute(Qt::WA_DeleteOnClose);
ui->mdiArea->addSubWindow(wCon);
wCon->setFixedSize(200,200);
int x, y;
    x = (this->width() - wCon->width())/2;
    y = (this->height() - wCon->height())/2;
wCon->move(x,y);
wCon->show();
// this = mainWindow that contains the MDI
// myWindow = QWidget class
// also tried : wCon->move(wCon->rect().center());

the new window stays at top left of the MDIarea and does not move to the new location (center of MDI area).

Any idea why ?

Hi,

@Xena_o said in Window widget not moving with move():

wCon->move(x,y);

you have to move your widget as QMdiSubWindow not as QWidget (otherwise it moves the widget content inside your MdiWindow and not the whole MdiWindow in your MdiArea.)

Try mdiArea->activeSubWindow()->move(x, y);
(or currentSubWindow())

@Pl45m4 thank you !

with your help i could figure out how the code should be:

wCon = new myWindow(this);

    QMdiSubWindow *cw = new QMdiSubWindow;
    cw->setWidget(wCon);

    //destroy window on close
    cw->setAttribute(Qt::WA_DeleteOnClose);

    //add window to MDI area
     ui->mdiArea->addSubWindow(cw);

    //put window in middle of MDI
    cw->move(wCon->rect().center());

    //show the window
    cw->show();

this code works well ! thanks !
