# Double the font size in QTextEdit

• Hi all,

I have used the following code to change some parts of the font size in the whole text edit:

@void testTextView :: setInsertTextColor(const QColor& color)
{
QTextCharFormat fmt;
fmt.setForeground(color);

QTextCursor cursor = m_edit -> textCursor();
cursor.mergeCharFormat(fmt);

m_edit -> mergeCurrentCharFormat(fmt);
}@

and after this I cannot change the whole font size, which contains the specific formats in the text edit by calling zoomIn/out.

is there any idea to solve the problem?
