CodePudding user response:

Clearly set enclosing. For the Region this is wrong,

CodePudding user response:

Every time when painting the rounded with a Rectangle arcRect? Position does not change?

CodePudding user response:

refer to the second floor MichaelGLX response:

every painting when rounded corners with a Rectangle arcRect? Position does not change?

Wrong, this how to delete ah!!

Is set work area is wrong, when you draw the rect width 1 to try? And set the work area to line that how click ah, you can fill up!
