[Qt-interest] How to change current line format in QTextEdit?

[程梁]

Thank you! I'll try this.

What I reaaly need is when users click a button, even if they don't selected
any text, the current line's format will be changed. Just like Windows Live
Writer 2011 adds heading tags.

Mutilple-cursor could solve my problem. But why setBlockCharFormat and these
functions cannot apply? What does it mean "If the cursor has no selection,
current block format will be changed." in the document?
