Hello,
I'm making a kind of a notepad with a PlainTextEdit...
But I have some questions.
1)The font size,is too small.How can I set it to a bigger one?
2)How can I make a thing like this in the menu,for the user?
3)I'd like to add a syntax highlighting for c++ to it as well..and I found the custom at the examples..but it doesn't seem to work.Is there any other and better way?

Thank you guys.
