-
The window have no title bar by default, so we can not move the window around with mouse. Inorder to make the window moveable, protected member function
setTitleBar(QWidget* titlebar)should be called in the MainWindow's Constructor, the widget "titlebar" should be a child widget of MainWindow, and it will act exactly same as SYSTEM Title Bar. -
Widget "titlebar" may has its own child widget, such as "close button" and "max button", and we can NOT move the window with "close button", which is what we want. However, a label widget "label1" on "titlebar" should not cover the moveable functionality, the protected member function
addBlacklistWidget(QWidget* widget)is designed to deal with this kind of situation, just calladdBlacklistWidget(ui->label1)in MainWindow's Constructor. -
setResizeableAreaWidth(int width = 5)can set width of an invisible border aera, inside this aera, window can be resized by mouse. -
setResizeable(bool resizeable)can set whether the window can be resized by mouse or not. -
Exampleforwindows shows the general usage.

WARNING: resize()/geometry()/setGeometry()/frameGeometry()/frameSize()/x()/y()/.etc function will not work right when the Window is Maximized, try not to use any of these function when the Window is Maximized (If you really want to fix these bugs, feel free to contact Bringer-of-Light) . But these function setContentsMargins()/contentsMargins()/getContentsMargins/contentsRect() can always works right, so you can use them anytime. Generally , it's always a good idea to use Qt Layout Management System instead of hard-code layout Management to avoid potential size-like/pos-like issue.
