QML如何将文本光标放在TextEdit元素的末尾 [英] QML How to put text cursor at the end of TextEdit element

问题描述

我有一个 QML TextEdit 元素，我计划添加一些文本并将光标放在末尾.我的方法:

I have a QML TextEdit element, I plan for append some text and put the cursor at the end. My method:

import QtQuick 1.1

Rectangle {
    color: "black"
    anchors.fill: parent
    focus: false

    TextEdit {
        id: txtCommands

        color: "lightGreen"
        anchors.fill: parent
        textFormat: TextEdit.RichText
        wrapMode: TextEdit.WordWrap

        font.family: "Consolas"
        font.pixelSize: 15
        focus: true

        MouseArea {
            anchors.fill: parent
            focus: false
        }

        Keys.onPressed: {
            console.log(event.text)

            switch (event.key) {
            case 16777234: // LEFT
            case 16777235: // UP
            case 16777237: // DOWN
            case 16777236: // RIGHT
                event.accepted = true
                break;

            case 16777220:  // Enter
                txtCommands.text = txtCommands.text + ">: "
                txtCommands.selectAll()
                txtCommands.cursorPosition = txtCommands.text.length
                break;
            }
        }
    }
}

但它不起作用.我该怎么做?

but it doesn't work. How can i do that?

推荐答案

1. 将 textFormat 设置为 TextEdit.PlainText，否则会有很多不可见的 html 代码.

2. 以下代码适用于我.

1. Set textFormat to TextEdit.PlainText because you have lots of invisible html code otherwise.

2. The following code works for me.

Keys.onReturnPressed: {
    event.accepted = true
    txtCommands.text = txtCommands.text + ">: "
    txtCommands.cursorPosition = txtCommands.text.length
}
