问题描述
Qt 提供了一种强大的自适应方式来处理 left-to-right 语言和 right-to-left 语言文本.但是我遇到了解决我的目标时遇到的问题.
Qt provides a powerful adaptive way to deal with left-to-right languages and right-to-left languages texts.But I encounter my problems dealing with my goals.
图片No.1我想要得到的东西
Picture No.1 What I want to get
第2张图片粘贴到基于QTextEdit的小部件时，我得到的是第1张图片
Picture No.2 What I got when paste to my QTextEdit based widget what picture no.1 shows
第3张图片，当我将文本方向设置为从左到右时，我得到了什么，如下所示:
QTextDocument *doc = ui->textEdit->document();
QTextOption textOption = doc->defaultTextOption();
textOption.setTextDirection(Qt::LeftToRight);
doc->setDefaultTextOption(textOption);
ui->textEdit->setDocument(doc);
Making it left-to-right aligned is not that hard,
but the result differs from what picture no.1 shows.
图片No.4当我尝试将文本添加到终端时，我得到了什么
Picture No.4 What I got when I try appending texts to the terminal
What I want to achieve is the fact that it shows like picture no.1 does,
and key-strikes make texts appended to the terminal
when the existting texts is terminated by a Arabic notation.
In a word,all I want is that it behave like left-to-right languages do
whether it contains right-to-left language characters or not.推荐答案
Unicode提供了 Directional Formatting Characters ，而 Qt 对此提供了很好的支持.这个想法来自@ VahidN.我的问题已部分通过这种方式解决，现在它可以正确显示双向字符串.
Unicode provides Directional Formatting Characters,and Qt supports it well.The idea comes from @VahidN.My problem is solved partly via this way,now it display bidirection string properly.
QString(QChar(0x200E))+strText; //LRM
QString(QChar(0x202D)) + strText + QString(QChar(0x202C)); //LRO...PDF
在此问题之前，我回答了，这可能有助于您找到自己的解决方案.
Before this question I answered another one,which maybe helpful for finding your own solution.
