Attributes

• radiusCorners: int

describe

• By setting a radiusCorners value, you can control the direction of the rounded corners.

RoundRectangle {
    width: 100; height: 50
    color: "lightblue"
    radius: 10
    radiusCorners: Qt.AlignLeft | Qt.AlignRight | Qt.AlignTop | Qt.AlignBottom }

example

properties document

• radiusCorners: int Sets the fillet position.
• Available values ​​for radiusCorners:

constant	value	describe
Qt. AlignLeft	0x0001	align to left edge
Qt. AlignRight	0x0002	align to right edge
Qt. AlignTop	0x0020	align to top
Qt. AlignBottom	0x0040	align to bottom

• Combination value ranges available for radiusCorners:
