QGraphicsTextItem RightToLeft 文本

发布于 2024-12-27 16:31:19 字数 536 浏览 1 评论 0原文

我必须将一些波斯语文本写入 QGraphicsTextItem ，但我找不到如何使 QGraphicsTextItem 写入 RightToLeft!。
任何人都可以帮助我吗？

我尝试了这种方法，但它对我不起作用：

class DiagramTextItem(QtGui.QGraphicsTextItem):

def __init__(self, parent=None, scene=None):
    super(DiagramTextItem, self).__init__(parent, scene)
    doc =QtGui.QTextDocument ('''شسشس
                              یییییگ''')
    txtOpt = QtGui.QTextOption()
    txtOpt.setAlignment(QtCore.Qt.AlignRight)
    doc.setDefaultTextOption(txtOpt)

谢谢。

看起来您可以将 QTextOption.setTextDirection 与 < a href="http://developer.qt.nokia.com/doc/qt-4.8/qt.html#LayoutDirection-enum" rel="nofollow">Qt.RightToLeft。

但请注意，您可能需要在设置文本之前设置方向：

class DiagramTextItem(QtGui.QGraphicsTextItem):
    def __init__(self, parent=None, scene=None):
        super(DiagramTextItem, self).__init__(parent, scene)
        doc = QtGui.QTextDocument()
        txtOpt = QtGui.QTextOption()
        txtOpt.setTextDirection(QtCore.Qt.RightToLeft)
        doc.setPlainText('''شسشس
                         یییییگ''')

如果这不起作用，请尝试将光标设置在 QGraphicsTextItem 上：

class DiagramTextItem(QtGui.QGraphicsTextItem):
    def __init__(self, parent=None, scene=None):
        super(DiagramTextItem, self).__init__(parent, scene)
        cursor = self.textCursor()
        format = cursor.charFormat()
        format.setLayoutDirection(QtCore.Qt.RightToLeft)
        cursor.setFormat(format)
        self.setTextCursor(cursor)
        self.setPlainText('''شسشس
                          یییییگ''')

It looks like you could use QTextOption.setTextDirection with Qt.RightToLeft.

But note that you may need to set the direction before you set the text:

class DiagramTextItem(QtGui.QGraphicsTextItem):
    def __init__(self, parent=None, scene=None):
        super(DiagramTextItem, self).__init__(parent, scene)
        doc = QtGui.QTextDocument()
        txtOpt = QtGui.QTextOption()
        txtOpt.setTextDirection(QtCore.Qt.RightToLeft)
        doc.setPlainText('''شسشس
                         یییییگ''')

If that doesn't work, try setting the cursor on the QGraphicsTextItem:

class DiagramTextItem(QtGui.QGraphicsTextItem):
    def __init__(self, parent=None, scene=None):
        super(DiagramTextItem, self).__init__(parent, scene)
        cursor = self.textCursor()
        format = cursor.charFormat()
        format.setLayoutDirection(QtCore.Qt.RightToLeft)
        cursor.setFormat(format)
        self.setTextCursor(cursor)
        self.setPlainText('''شسشس
                          یییییگ''')
