Window geometry

SPlatten

I'm calling geometry on a window it looks like the rectangle includes everything including the title bar. Is there a function or facility to return just the geometry of the inner window canvas?

@jsulm , ok thats for a QMainWindow, is it also valid for a QWindow?

@SPlatten According to https://doc.qt.io/qt-5/qwindow.html#geometry "Returns the geometry of the window, excluding its window frame". So, the frame should not be part of geometry.

I've tried the following:

   QWidget* pobjWidget = pobjParent->pobjGetWidget();

   if ( pobjWidget != nullptr ) {
       QMainWindow* pobjMainWindow = static_cast<QMainWindow*>(pobjWidget);
       QWidget* pobjCentral = pobjMainWindow->centralWidget();

And single stepped using the debugger, it will not step over centralWidget() which leads me to believe that as I am defining my widget as QWindow that it cannot be cast to a QMainWindow.

@SPlatten said in Window geometry:

Of course not

SPlatten

So my original question still stands how to get the geometry of the area inside the frame? I'm currently looking at frameMargins.

@SPlatten As I said above: according to the documentation QWindow::geometry() should not contain window frame.
Where do you call geometry()? I hope not in constructor.

SPlatten

No, from the eventFilter:

bool clsXMLnode::eventFilter(QObject* pobjObject, QEvent* pobjEvent) {
    if ( pobjEvent->type() == QEvent::Resize ) {
    ....
    }
    return QObject::eventFilter(pobjObject, pobjEvent);
}

jsulm

@SPlatten https://doc.qt.io/qt-5/qwidget.html#resizeEvent
"When resizeEvent() is called, the widget already has its new geometry. The old size is accessible through QResizeEvent::oldSize()."

SPlatten

I'm want the inner size so I can use it when the window is resized.

jsulm

@SPlatten But how do you know that you get size including window frame?
Qt documentation clearly states that geometry() returns the size without window frame.
And what I wanted to say with my previous post: if you call geometry() in resize event you get new size, not old.

SPlatten

From the geometry I can see it includes the title area.
