我找到了C ++ code,但我无法使用Python使它正常工作。 我不懂C ++,就像那里的递归...
class VerticalTextDelegate(QtGui.QStyledItemDelegate):
def __init__(self, parent):
super(VerticalTextDelegate, self).__init__()
def paint(self, painter, option, index):
optionCopy = QtGui.QStyleOptionViewItem(option)
rectCenter = QtCore.QPointF(QtCore.QRectF(option.rect).center())
painter.save()
painter.translate(rectCenter.x(), rectCenter.y())
painter.rotate(-90.0)
painter.translate(-rectCenter.x(), -rectCenter.y())
optionCopy.rect = painter.worldTransform().mapRect(option.rect)
# recursion here, I don't understand how it works in C++
# self.paint(painter, optionCopy, index)
self.painter.restore()
def sizeHint(self, option, index):
val = QtGui.QSize(self.sizeHint(option, index))
return QtGui.QSize(val.height(), val.width())
运行代码:
item = QtGui.QTableWidgetItem("test")
self.table_widget.setItem(2, 0, item)
self.table_widget.setItemDelegateForColumn(0,VerticalTextDelegate(self))
答案 0 :(得分:1)
如果您参考的是C++
示例,您会发现VerticalTextDelegate::paint
实现基本上是在修复QPainter
转换,然后调用基类实现{{1 }}。您也需要这样做(未经测试)...
QStyledItemDelegate::paint
