我有一个树小部件,我正在添加项目。现在,我需要在选择项目时调用自定义过程,或者取消选择之前选择的项目(注意:我正在学习Python和Qt - 后者似乎对我来说太过分了。)
for i in vector:
parent = QtGui.QTreeWidgetItem(treeWidget)
parent.setText(0, i[0])
parent.setText(1, i[1])
parent.setText(2,i[2])
parent.setCheckState(0,QtCore.Qt.Unchecked)
答案 0 :(得分:0)
尝试树小部件选择模型的selectionChanged信号:
selmodel = self.treeWidget.selectionModel()
selmodel.selectionChanged.connect(self.handleSelection)
...
def handleSelection(self, selected, deselected):
for index in selected.indexes():
item = self.treeWidget.itemFromIndex(index)
print('SEL: row: %s, col: %s, text: %s' % (
index.row(), index.column(), item.text(0)))
for index in deselected.indexes():
item = self.treeWidget.itemFromIndex(index)
print('DESEL: row: %s, col: %s, text: %s' % (
index.row(), index.column(), item.text(0)))
