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，它会显示一个显示日期和制作文件的工具提示。我也喜欢这个数据附带的图像。

是否可以将图像插入工具提示？对于QTreeView中的每个项目，我都希望弹出特定的图像和文本。如果不能用工具提示完成还有其他选择吗？

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：感谢ekhumoro快速简便的解决方案！这是更新的代码和link到一些帮助我格式化工具提示的HTML基础知识：

来自PySide导入QtCore，QtGui 来自shiboken import wrapInstance 导入maya.OpenMayaUI作为mui

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

Answer 1

工具提示接受富文本，这意味着您可以使用属于Supported HTML Subset的任何标记。这包括img标记，因此您只需要：

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

PySide：将图像添加到工具提示中
