Question

伙计们！我有两个QTreeView树和一个QPushButton。我如何理解我点击的树项目？例如，我点击了treeView1中的项目，并获得如下消息： “您在treeView1中选择项目”

def button(self):
    index = self.treeView1.currentIndex()
    node = index.internalPointer()
    if node is not None:
         print("You select item in treeView1 " + node.name())
    else:
         index = self.treeView2.currentIndex()
         node = index.internalPointer()
         print("You select item in treeView2 " + node.name())

它有效，但我认为这是非常糟糕的解决方案.. 我怎么做这个例子呢？非常感谢！对不起我的英文：）

Answer 1

这很容易。

首先设置两个信号

QtCore.QObject.connect(self.treeView1 , QtCore.SIGNAL("clicked (const QModelIndex&)") , self.clickedTree1)
QtCore.QObject.connect(self.treeView2 , QtCore.SIGNAL("clicked (const QModelIndex&)") , self.clickedTree2)

设置完信号后，您需要定义广告位def clickedTree1(self,index)和def clickedTree2 (self,index)。

def clickedTree1(self,index):
    node = index.internalPointer()
    print("You select item in treeView1 " + node.name())

def clickedTree2(self,index):
    node = index.internalPointer()
    print("You select item in treeView2 " + node.name())

好的，我再次阅读了这个问题，并且我想要在点击按钮时打印。
