How to change the background of a text bloc in a text document in Qt
is there a way to change the background color of a QTextBlock in a QTextDocument without using a subclass of QAbstractTextDocumentLayout. I have tried many ways and the effects are null. I am trying from the textCursor() method of a QPlainTextEditor and it seems practically everything is const.
You could try the merge methods:
QTextCursor cur = edit->textCursor(); QTextCharFormat fmt; fmt.setBackground(QBrush(Qt::gray)); cur.mergeBlockCharFormat(fmt);
Could this example help you ?
You can find it also in QtDemos, on Demonstrations->Text Edit.
Hope it helps!
