Without custom delegate everything works fine:
But my tableview shows search results and part of the text needs to be bold to indicate where it matches the searched query.
Once I use the delegate to get html tags working, the text that overflows cells is not cliped and replaced with ellipsis:
Heres my delegate:
class HTMLDelegate(QStyledItemDelegate):
def __init__(self, parent=None):
super().__init__()
self.doc = QTextDocument(self)
def paint(self, painter, option, index):
painter.save()
options = QStyleOptionViewItem(option)
self.initStyleOption(options, index)
self.doc.setHtml(options.text)
options.text = ""
style = QApplication.style() if options.widget is None \
else options.widget.style()
style.drawControl(QStyle.CE_ItemViewItem, options, painter)
ctx = QAbstractTextDocumentLayout.PaintContext()
if option.state & QStyle.State_Selected:
ctx.palette.setColor(QPalette.Text, option.palette.color(
QPalette.Active, QPalette.HighlightedText))
textRect = style.subElementRect(QStyle.SE_ItemViewItemText, options)
#textRect.adjust(0, 0, 0, 0)
painter.translate(textRect.topLeft())
self.doc.documentLayout().draw(painter, ctx)
painter.restore()
def sizeHint(self, option, index):
return QSize(self.doc.idealWidth(), self.doc.size().height())
also if I would add line
self.doc.setTextWidth(option.rect.width())
it would cut the text to the other line(I increased row height to show it):
I thoughtI had it in my delegate, its in all other answers around here, well it does the clipping correctly, though no fancy ellipsis, but thats ok I guess. I assumed previously that theres just some value that I have to enable to get clipping ellipsis, but I am starting to see that it could be considerably more complicated than that, that I might actually need to edit the text itself depending on area rectangle - vs text width taken and adjust on every column resize or some stuff
oh, how I wish they would just make option to enable html rich text with the default delegate
