C++ Qt中setBrush我只发现了一种实现方式,为何以下语句中有两种?
painter.setBrush(QBrush(Qt::blue,Qt::Dense3Pattern))
painter.setBrush(Qt::blue)
Qt帮助文档是这样的:
void QPainter::setBrush(const QBrush &brush) Sets the painter's brush to the given brush. The painter's brush defines how shapes are filled. See also brush() and Settings. void QPainter::setBrush(Qt::BrushStyle style) This is an overloaded function. Sets the painter's brush to black color and the specified style. |
