我有 1024x768 分辨率的窗口，当点击或鼠标悬停时，我想找到 x、y 值。我怎样才能做到这一点？
import sys
from PyQt4 import QtGui, QtCore
class Example(QtGui.QWidget):
def __init__(self):
super(Example, self).__init__()
self.initUI()
def initUI(self):
qbtn = QtGui.QPushButton('Quit', self)
#qbtn.clicked.connect(QtCore.QCoreApplication.instance().quit)
qbtn.clicked.connect(self.test)
qbtn.resize(qbtn.sizeHint())
qbtn.move(50, 50)
self.setGeometry(0, 0, 1024, 768)
self.setWindowTitle('Quit button')
self.setWindowFlags(self.windowFlags() | QtCore.Qt.FramelessWindowHint)
self.show()
def test(self):
print "show the position of mouse cursor in screen resolution: x is ?? , y is ??"
def main():
app = QtGui.QApplication(sys.argv)
ex = Example()
sys.exit(app.exec_())
if __name__ == '__main__':
main()

The other way to get (x,y) coordinates:
获取 (x,y) 坐标的另一种方法：
def mouseReleaseEvent(self, QMouseEvent):
print('(', QMouseEvent.x(), ', ', QMouseEvent.y(), ')')
