QListWidget项上面的PyQt5 cursor如何弹出WhatsThis文档？

Question

How to give a definition for each item in QListWidget, so that the cursor changes to WhatsThis Cursor and pops an doc of explication when the cursor is over it?

Something like this but for an item of QListWidget

I tried simply:

for i, def in zip(range(self.listWidget.count()), some_doc):
    self.listWidget.item(i).setWhatsThis(def)

But the doc didn't show up

That appears to be the correct way to set the WhatsThis . However, you state that you want this to appear on hovering, which is instead the tooltip property.

solution:

for i, def in zip(range(self.listWidget.count()), some_doc):
    self.listWidget.item(i).setToolTip(def)

If you want this behavior only in WhatsThis mode, you will have to subclass the QListWidgetItem and set the tooltip to only return when QtWidgets.QWhatsThis.inWhatsThisMode() is true.

If you really are just having problems with the WhatsThis property working on click, we will need to see more of your code and possibly a screenshot of your window. Because like I said, the loop at the beginning should work at just setting the normal property.
