PySide：将图像添加到工具提示

Question

我正在构建一个列出目录中文件的工具。当您将鼠标悬停在每个文件上时，它会显示一个工具提示，显示日期和创建文件的人。我还想要一张图片来伴随这些数据。

是否可以在工具提示中插入图片？对于 QTreeView 中的每个项目，我希望弹出一个特定的图像和文本。如果无法通过工具提示完成，是否还有其他选择？

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 )

解决方案： 感谢 ekhumoro 提供快速简便的解决方案！这是更新后的代码和一些 HTML 帮助我格式化工具提示的基础知识的 link：

从 PySide 导入 QtCore、QtGui 从 shiboken 导入 wrapInstance 将 maya.OpenMayaUI 导入为 mui

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

工具提示接受富文本格式，这意味着您可以使用属于 Supported HTML Subset 的任何标记。这包括一个 img 标签，所以你只需要这样的东西：

    item.setToolTip('<b>%s</b><br><img src="%s">' % (filename, iconpath))
