How to word wrap a QTreeWidgetItem

问题

I have to populate a QTreeWidget with items (or children of items) that may happen to be too long to fit in a single line, so I'm looking for a way to word wrap them.

I thought

myQTreeWidget.setWordWrap(True)

(done via QtDesigner4) would have done the job, but that doesn't seem to be the case.

I don't know if it is relevant, but the tree is enveloped in a splitter frame, so the wrapping should be somehow dynamic to allow resizing of the splitter.

Any ideas? I use PyQt4, but hints in any language/binding would be appreciated.

回答1:

I successfully found a workaround: i envelope a QLabel in the WidgetItem, setting the QLabel to have word wrap capabilities.

item = QTreeWidgetItem()
label = QLabel('long text here')
label.setWordWrap(True)

MyTree.addTopLevelItem(item)
MyTree.setItemWidget(item, 0, label)

the behaviour is exactly the one desired!!

回答2:

setWordWrap just causing wrapping around word-boundaries... it will NOT force anything on to a new line.

What you are looking for is not possible with the default QTreeWidget. I suggest displaying text that is too long in an alternative way, such as mouse-over text or a separate label. TreeViews should not contain more then one line of text per item.
