QML framework Bug found , text Area and Markdown, garbage remain after emptying content
Unsolved
QML and Qt Quick
-
using an ordinary text area in QML, setting it up with a markup formatting. using the header "#" markup.
after deleting all the content using backspace, it will appear that the text area is empty.
after typing a single letter, the text will appear as usual but, the actual content of the TextArea.txt will contant the "#" deleted previously.here is the QML code
import QtQuick 2.15 import QtQuick.Window 2.15 import QtQuick.Controls 2.12 Window { width: 640 height: 480 visible: true title: qsTr("Hello World") id: mainWindow TextArea { id: mainText anchors.fill : parent textFormat: TextEdit.MarkdownText text: "# Header" Keys.onPressed: { if(event.key === Qt.Key_B && (event.modifiers & Qt.ControlModifier )){ // for debugging console.debug("main text is ", mainText.text); } } } }
Steps to reproduce
- Here I have a TextArea with Markdown formatting, after running this application, it will display the correct header.
- Now, delete the content of the TextArea using backspace until all text is gone.
- once confirmed, press Ctrl + B, it will print/dump the content of the text area, it is empty and length is 0.
- now type a single character in the text area, it will appear as expected in the running UI... BUT..
- when pressing Ctrl+B again to dump the content of mainText.text, the text Area will have the "#" plus the character typed in #4. Ex: "# s" assuming "s" was the character typed.
