Question

我正在尝试从QTreeView获取所选项目的字符串。

我从这里PAGE获取了一些提示，并从Qt文档中略微提出了一些提示，但我没有取得任何进展。想法？

这是一个示例代码。我想这样做，如果我点击第1行，它将打印出“第1页”

from PySide import QtCore, QtGui
from shiboken import wrapInstance
import maya.OpenMayaUI as mui

def get_parent():
    ptr = mui.MQtUtil.mainWindow()
    return wrapInstance( long( ptr ), QtGui.QWidget )

偶然发现了我的回答HERE。这是编辑后的插槽：

# slots --------------------------------------------------------------
def on_click(self, item ):
    # print item from first column
    index = self.tv_file_list.selectedIndexes()[0]
    item = self.tv_model.itemFromIndex(index).text()
    print item
