当用户从titleBar移动Qdialog时,我尝试找到一种捕获事件的方法。 我的目标是附加一个拖动事件,以将我的自定义qdialog停靠在mainWindow中。 (在Linux上)
换句话说,要做ockockwidgets的事情(我可以使用dockwidget),我必须对Custom Qdialog(或带有Qt.Window标志的小部件)做同样的事情
我在c ++ Qt源代码中看到的要比QDockWidget要多,他们使用这种东西:
bool QDockWidget::event(QEvent *event)
{ [...]
case QEvent::NonClientAreaMouseMove:
case QEvent::NonClientAreaMouseButtonPress:
case QEvent::NonClientAreaMouseButtonRelease:
case QEvent::NonClientAreaMouseButtonDblClick:
d->nonClientAreaMouseEvent(static_cast<QMouseEvent*>(event));
但是当我尝试在pyside上捕获此类事件时,我什么也没收到:
def event(self, e):
print('event %s' % e.type())
return super(myDyalig,self).event(e)
event PySide2.QtCore.QEvent.Type.ActivationChange
event PySide2.QtCore.QEvent.Type.UpdateRequest
event PySide2.QtCore.QEvent.Type.Paint
# I recieve only this move event when user stop moving (when he
# release the button)
event PySide2.QtCore.QEvent.Type.Move
event PySide2.QtCore.QEvent.Type.WindowActivate
event PySide2.QtCore.QEvent.Type.ActivationChange
event PySide2.QtCore.QEvent.Type.UpdateRequest
event PySide2.QtCore.QEvent.Type.Paint
任何想法如何做到这一点? (或另一个使用qdialog实现拖动事件的想法)
编辑:
一个最小的例子:
from PySide2.QtCore import *
from PySide2.QtGui import *
from PySide2.QtWidgets import *
class CustomDialog(QDialog):
def __init__(self, parent=None):
super(CustomDialog,self).__init__(parent)
self.setFixedSize(QSize(200,200))
def event(self, e):
print('event %s' % e.type())
return super(CustomDialog,self).event(e)
def main():
import sys
app = QApplication(sys.argv)
dial = CustomDialog()
dial.show()
sys.exit(app.exec_())
if __name__ == '__main__':
main()
答案 0 :(得分:0)
您需要安装事件过滤器:
def __init__(self, parent=None):
super().__init__(parent)
#...
self.installEventFilter(self)
def eventFilter(self, obj, event):
if event.type() in (QEvent.NonClientAreaMouseButtonPress, QEvent.NonClientAreaMouseButtonPress, QEvent.Move):
print(event)
return super().eventFilter(obj, event)
