"QT5 Development and examples" 17, a dialog box coordinates the parameter display

The coordinate parameter of a dialog box shows an introduction

This is to get the length and width of the dialog, coordinates of each point, relative coordinates, relative coordinates of the parent window, relative to the coordinates of the desktop.

Well, I found that more than 1M photos can not be uploaded, 666666, I remember it seems to be 2M, blame me too naïve???
