Qt ignores CSS in QTextDocument

StackOverflow https://stackoverflow.com/questions/15730224

Frage

Here is a small snippet of my code, I don't know why but Qt is ignoring the css.

QTextDocument *mTextDocument = new QTextDocument(0);
QTextEdit *textEdit = new QTextEdit(0);
mTextDocument->setDefaultStyleSheet(QString::fromUtf8("body{background-color: rgb(0,111,200);}"));
QTextCursor *_cursor = new QTextCursor(mTextDocument);
textEdit->setDocument(mTextDocument);
_cursor->insertBlock();
_cursor->insertHtml("<html><body><p>Hello world</p></body></html>");
textEdit->show();

I'm using Qt 4.8.

War es hilfreich?

Lösung

Your document already has html and body tags, so they are simply ignored when they are found in insertHtml.

If you were using QTextEdit::setHtml, they would be new elements and the default stylesheet would be applied to them.
