Opening a dialogue next to main window
-
I am opening a Dialogue to the left of the main window. There is plenty of room and I know how to fix it if there isn't (using a max function) - this is just the bare bones of the problem:
myDlg->show(); int xx = x() - myDlg->frameGeometry().width(); myDlg->move(xx, y());According to the documentation this ought to cause the right hand edge of the dialogue to be up against the left hand edge of the main window. It isn't! There's a (approx) 15 pixel gap! Is this caused by Win10's 'shadow' nonsense - which I have turned off - or something else? Help would be appreciated.

@BrianE
use geometry().x() -
I can't! I get an error message:
D:\Qt Projects\xxx.cpp:280: error: '((MainWindow*)this)->QWidget::geometry' does not have class type int xx = geometry.x() - myDlg->frameGeometry().width(); ^@BrianE said in Opening a dialogue next to main window:
((MainWindow*)this)->QWidget::geometry
That looks odd
are you casting this ?All widgets have geometry()

myDlg->show(); int xx = mainWin->geometry().right(); myDlg->move(xx, y()); -
The only thing that has worked so far is this:
myDlg->show(); int xx = MainWindow::geometry().x() - myDlg->frameGeometry().width(); myDlg->move(xx, y());However, there is still a six or seven pixel gap between RH edge of myDlg and LH edge of MainWindow.
More:
int xx = MainWindow::geometry().x() - myDlg->geometry().width();gives you an big overlap! and
int xx = MainWindow::frameGeometry().x() - myDlg->geometry().width();gives me as close to what I want as we're going to get ie one/two pixel overlap which is understandable.
This does solve the problem, so thanks for the input, but is absolutely not what I was expecting from the documentation. Mind you, how anything works in Win10 is nothing short of miraculous anyway.

????? That's exactly what I wanted to do! The top left corner of myDlg to be myDlg's width to the left of MainWindow's top left. Basically that means Dlg.TL = Main.TL - Dlg.W and my original code used the documented parts of the window as required. It was using the 'correct' parts that gave the gap between Dlg.R and Main.L and I still don't know why!
