【问题描述】:
我尝试在 Pyside 中实现How to distinguish between mouseReleaseEvent and mousedoubleClickEvent on QGrapnhicsScene 中描述的方法,但我必须添加一个粗略的标志以防止在双击第二个按钮释放后显示单击。
有没有更好的办法?
import sys
from PySide import QtGui, QtCore
class Example(QtGui.QWidget):
def __init__(self):
super(Example, self).__init__()
"""an attempt to implement
https://stackoverflow.com/questions/18021691/how-to-distinguish-between-mousereleaseevent-and-mousedoubleclickevent-on-qgrapn
main()
connect(timer, SIGNAL(timeout()), this, SLOT(singleClick()));
mouseReleaseEvent()
timer->start();
mouseDoubleClickEvent()
timer->stop();
singleClick()
// Do single click behavior
"""
self.timer = QtCore.QTimer()
self.timer.setSingleShot(True)
# had to add a "double_clicked" flag
self.double_clicked = False
self.timer.timeout.connect(self.singleClick)
self.setGeometry(300, 300, 250, 150)
self.setWindowTitle('Single click, double click')
self.show()
def mouseReleaseEvent(self, event):
if not self.double_clicked:
self.timer.start(200)
else:
self.double_clicked = False
def mouseDoubleClickEvent(self, event):
self.timer.stop()
self.double_clicked = True
print 'double click'
def singleClick(self):
print 'singleClick'
if __name__ == '__main__':
app = QtGui.QApplication(sys.argv)
ex = Example()
sys.exit(app.exec_())
