Can I bold my QLineEdit border , don't use setStyleSheet()?

Hi guys:

I want to bold thi bordre of QLineEdit, and set the background semitransparentï¼›I Know it can bold the bordre using setStyleSheet(), but the setStyleSheet() can't semitransparent the backgroud. so it seems conflict.


Help me, please.

Thancks.

Well, you can set semitransparent backgrounds with style sheets using rgba(). But if you don't like, subclass and do the background painting yourself.

Oh！　yes, it works. I always thought the CSS can't set the semitransparent, so I repaint most of my widget.

Now I know the css can set the semitransparent .

Thanks a lot.:o:o:o:o
