可以通过指定RGB或CMYK或HSV值来选择自定义颜色。
以下示例实现了其中一些方法。
import sys
from PyQt4.QtGui import *
from PyQt4.QtCore import *
class Example(QWidget):
def __init__(self):
super(Example, self).__init__()
self.initUI()
def initUI(self):
self.text = "hello world"
self.setGeometry(100,100, 400,300)
self.setWindowTitle('Draw Demo')
self.show()
def paintEvent(self, event):
qp = QPainter()
qp.begin(self)
qp.setPen(QColor(Qt.red))
qp.setFont(QFont('Arial', 20))
qp.drawText(10,50, "hello Pyth
on")
qp.setPen(QColor(Qt.blue))
qp.drawLine(10,100,100,100)
qp.drawRect(10,150,150,100)
qp.setPen(QColor(Qt.yellow))
qp.drawEllipse(100,50,100,50)
qp.drawPixmap(220,10,QPixmap("python.jpg"))
qp.fillRect(200,175,150,100,QBrush(Qt.SolidPattern))
qp.end()
def main():
app = QApplication(sys.argv)
ex = Example()
sys.exit(app.exec_())
if __name__ == '__main__':
main()
上面的代码产生以下输出-
