Highlight a line of a TextEdit

[Bettina]

I know how to select (again not too hard) but need to know how to change the color of a single line from a QTextEdit?

Example:
Line 1
Line 2
Line 3 highlighted
Line 4
Line 5 highlighted

To select, use QTextCursor like this (you can move the cursor before selecting with setPosition ( QTextCursor: KeepAnchor)):

 QTextCursor textEdit = cursor -> TextCursor ();
 cursor. setPosition (n QTextCursor: KeepAnchor);
 textEdit -> setTextCursor (cursor);

The QTextCursor class offers an API to access and modify QTextDocuments, TextEdit does indeed support the desired display of text/color/background combination and even that can be further edited.

// Style Sheet
textEdit->setStyleSheet("color: black; background-color: white; selection-color: white; selection-background-color: black;");

 QTextCursor textEdit = cursor -> TextCursor () / / It gets a QTextCursor the text box
 cursor. setPosition (n QTextCursor: KeepAnchor) / / The location n is the position recovered by indexOf ( "test") on textEdit-> toPlainText ()
 textEdit -> setTextCursor (cursor) / / Used in this case to ensure that the selection is visible to the user
