Question

我正在使用自定义模型实现QTableView，我需要一个如下所示的单元格： http://oi47.tinypic.com/2jirkw.jpg

目前我使用下面的代表（改编自其他答案）在单个单元格上绘制一个标记（html彩色文本），单击整个单元格更改标记。

class HTMLDelegate(QtGui.QStyledItemDelegate):
    def Doc(self, options):
        if options.text == "0":
            return ""
        elif options.text == "1":
            return "<b><font align='right' color='green'>V</font></b>"
        elif options.text == "2":
            return "<font align='right' color='#FF8400'>!!</font>"
        elif options.text == "3":
            return "<b><font align='right' color='#CC0000'>F</font></b>"
        elif options.text == "4":
            return "<b><font align='right' color='#000000'>X</font></b>"

    def paint(self, painter, option, index):
        options = QtGui.QStyleOptionViewItemV4(option)
        self.initStyleOption(options,index)

        style = QtGui.QApplication.style() if options.widget is None else options.widget.style()

        doc = QtGui.QTextDocument()

        background = None
        doc.setHtml(self.Doc(options))

        options.text = ""
        style.drawControl(QtGui.QStyle.CE_ItemViewItem, options, painter);

        ctx = QtGui.QAbstractTextDocumentLayout.PaintContext()

        # Highlighting text if item is selected
        #if (optionV4.state & QStyle::State_Selected)
        #    ctx.palette.setColor(QPalette::Text, optionV4.palette.color(QPalette::Active, QPalette::HighlightedText));

        textRect = style.subElementRect(QtGui.QStyle.SE_ItemViewItemText, options, None)
        painter.save()
        if background:
            painter.fillRect(options.rect, QtCore.Qt.yellow)
        painter.translate(textRect.topLeft())
        painter.setClipRect(textRect.translated(-textRect.topLeft()))

        doc.documentLayout().draw(painter, ctx)

        painter.restore()

    def editorEvent(self, event, model, option, index):
        if not (index.flags() & QtCore.Qt.ItemIsEditable) > 0:
            return False

        # Do not change the checkbox-state
        if event.type() == QtCore.QEvent.MouseButtonRelease or event.type() == QtCore.QEvent.MouseButtonDblClick:
            if event.button() != QtCore.Qt.LeftButton:
                return False
            if event.type() == QtCore.QEvent.MouseButtonDblClick:
                return True
        elif event.type() == QtCore.QEvent.KeyPress:
            if event.key() != QtCore.Qt.Key_Space and event.key() != QtCore.Qt.Key_Select:
                return False
        else:
            return False

        # Change the flag-state
        self.setModelData(None, model, index)
        return False


    def setModelData (self, editor, model, index):
        '''
        The user wanted to change the old flag into the next
        '''
        #newValue = not bool(index.model().data(index, QtCore.Qt.DisplayRole))
        #model.setData(index, newValue, QtCore.Qt.EditRole)
        oldFlagIndex = model.index(index.row(), COD_COL_FLAGS)
        oldFlag = model.data(oldFlagIndex)

        if type(oldFlag) == long:
            newFlag = oldFlag + 1
            if newFlag > 4:
                newFlag = 0
        else:
            newFlag = 0
        model.setData(index, newFlag, QtCore.Qt.EditRole)

我怎样才能做到这一点？我想到的选项是：

向右侧绘制文字（丰富或简单）和像素图的代表
绘制两个文本字符串（一个普通文本和一个富文本，或两个富文本）的委托，左边一个，右边一个

作为练习，但不是应用程序所必需的，只有在点击它而不是整个单元格时触发标志更改才会很好。

paint事件有一个名为option的参数，该参数应该包含一个rect对象。那个rect对象是绘制内容的边界。您应该能够更改该矩形的宽度，并为您想要绘制第二部分的位置创建一个新的矩形。

rect = options.rect
options.rect = QtCore.QRect(rect.x(), rect.y(), rect.width()/2, rect.height())
style.drawControl(QtGui.QStyle.CE_ItemViewItem, options, painter);
options.rect = QtCore.QRect(rect.x()+rect.width()/2, rect.y(), rect.width()/2, rect.height())
options.text = "right side"
style.drawControl(QtGui.QStyle.CE_ItemViewItem, options, painter);

PySide委托QTableView上的文本和勾选
