问题
I'm building a tool that lists files in a directory. When you hover over each file it shows a tooltip displaying the date and who made the file. I'd also like an image to accompany this data.
Is it possible to insert an image into a tooltip? For each item in the QTreeView I'd like a specific image and text to popup. If it can't be done with tooltips are there other alternatives?

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

SOLUTION: Thanks to ekhumoro for the quick and easy solution! Here's the updated code and a link to some HTML basics that helped me format the tooltip:

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

Tooltips accept rich-text, which means you can use any markup that is part of the Supported HTML Subset. This includes an img tag, so all you need is something like:
item.setToolTip('<b>%s</b><br><img src="%s">' % (filename, iconpath))
