This article mainly introduces PYQT5 every day must learn to create a window center effect, so that the application window display in the center of the screen, with a certain reference value, interested in small partners can refer to

The example of this article for you to share how PYQT5 can create a desktop screen on the center window of the specific code for everyone to refer to, the specific content is as follows

The Qtgui.qdesktopwidget class provides information about the user's desktop, including the screen size.

Self.center ()

Place the code for the Center window in the Custom Center () method.

qr = Self.framegeometry ()

The Framegeometry () method allows us to create an invisible rectangle and set its own width and height based on the width height of the main window. The simple idea is to assign the geometry of the control (Qwidget) to the QR

CP = Qdesktopwidget (). Availablegeometry (). Center ()

Calculate the screen resolution of your monitor. Based on the obtained resolution we get the center point of the screen.

Qr.movecenter (CP)

Our rectangle (QR) already has width and height, now set the center of the move rectangle (movecenter) to the center point (CP) of the screen, the size of the rectangle is constant.

Self.move (Qr.topleft ())

Move the upper-left corner of the application window to the upper-left corner of the qr rectangle, allowing the application window to appear in the center of the screen.

After the program executes
