如何重置QML Textarea中丰富文本的样式

发布于 2025-02-08 20:35:56 字数 759 浏览 0 评论 0原文

如果我在QML Textarea中插入丰富的文本，它将保留该样式（文本颜色，下划线等）以获取进一步的输入。有没有办法防止这种情况发生？

示例：

import QtQuick 2.12
import QtQuick.Window 2.12
import QtQuick.Controls 2.12

Window {
    width: 640
    height: 480
    visible: true
    title: qsTr("Hello World")

    TextArea {
        id: textArea
        textFormat: Qt.RichText
        focus: true
        selectByMouse: true
        selectByKeyboard: true

        Keys.onPressed: {
            if (event.text === "@") {
                textArea.text += "<a href='mentioned://user'>@User</a>";
                event.accepted = true
            }
        }
    }
}

当我输入“@”字符时，它将插入＆lt; a＆gt;链接，但是当我继续键入其他字符时，它会将它们附加到链接上，就像它们是其中的一部分一样。如何在不附加到链接（标签）的情况下继续键入新段落？

If I insert rich text in QML TextArea, it will preserve that style (text color, underline etc.) for further inputs. Is there a way to prevent that from happening?

Example:

import QtQuick 2.12
import QtQuick.Window 2.12
import QtQuick.Controls 2.12

Window {
    width: 640
    height: 480
    visible: true
    title: qsTr("Hello World")

    TextArea {
        id: textArea
        textFormat: Qt.RichText
        focus: true
        selectByMouse: true
        selectByKeyboard: true

        Keys.onPressed: {
            if (event.text === "@") {
                textArea.text += "<a href='mentioned://user'>@User</a>";
                event.accepted = true
            }
        }
    }
}

When I enter "@" character it will insert the <a> link instead, but when I continue typing other characters it will append them to the link, as if they are a part of it. How can I continue typing a new paragraph, without appending to the link ( tag)?

标签解决问题后添加一个空格：

Window {
width: 640;
height: 480;
visible: true;
title: qsTr("Code from @Meliodas on StackOverflow");

    TextArea {
        id: textArea;
        textFormat: Qt.RichText;
        focus: true;
        selectByMouse: true;
        selectByKeyboard: true;

        Keys.onPressed: (event) => {
            if (event.text === "@") {
                // HERE
                insert(cursorPosition, "<a href='mentioned://user'>@User</a> ");
                event.accepted = true;
            }
        }
    }
}

请注意，我享有修改其他代码的自由：

警告告诉我隐式事件参数已弃用

Adding a whitespace after the tag solves the problem :

Window {
width: 640;
height: 480;
visible: true;
title: qsTr("Code from @Meliodas on StackOverflow");

    TextArea {
        id: textArea;
        textFormat: Qt.RichText;
        focus: true;
        selectByMouse: true;
        selectByKeyboard: true;

        Keys.onPressed: (event) => {
            if (event.text === "@") {
                // HERE
                insert(cursorPosition, "<a href='mentioned://user'>@User</a> ");
                event.accepted = true;
            }
        }
    }
}

Note that I took the freedom of modifying other pieces of your code :

insert() instead of text += to avoid automatic newlines
explicitly defining event to silence a warning telling me implicit event parameters are deprecated
