示例1: mouseReleaseEvent
# 需要導入模塊: from PyQt4.Qt import QTreeWidget [as 別名]
# 或者: from PyQt4.Qt.QTreeWidget import mouseReleaseEvent [as 別名]
def mouseReleaseEvent(self, ev):
item = self.itemAt(self._mouse_press_pos)
if item:
col = self.header().logicalIndexAt(self._mouse_press_pos)
# pass event to parent
QTreeWidget.mouseReleaseEvent(self, ev)
# now see if the item was expanded or collapsed because of the event. Only emit signal if this was
# not the case (i.e. swallow the clicks that have to do with expansion/collapse of items)
if item and item is not self._expanded_item:
self.emit(SIGNAL("mouseButtonClicked"), ev.button(), item, self._mouse_press_pos, col)
