custom scroll bar for QTextEdit

[ArkKup]

Hi,

I'd like to create some custom scroll bar for my QTextEdit. I've found good hint to hide original scroll bar and create a bit of padding inside the QTextEdit for the custom QScrollBar
then in that area manually set QScrollBar.

QScrollBar *sBar = new QScrollBar();
edit->setStyleSheet("padding-right: 10");

QScrollBar *sBar = new QScrollBar();
edit->setStyleSheet("padding-right: 10");

To copy to clipboard, switch view to plain text mode 

but how do I set QScrollBar to the padded area ?

You don't need to add padding, simply call

edit->setVerticalScrollBar (sBar)

edit->setVerticalScrollBar (sBar)

To copy to clipboard, switch view to plain text mode 

It will replace original scrollbar.

@ lanz:
this will not work for me since this scroll bar is dependent on QTextEdit and I need to have it independent from text, that's why I'd set new on in the padded area.

I see. Then I think you may create parent widget and add text edit with hidden scrollbar and your custom bar as its children.

Just out of curiosity, why are you need scrollbar that is independent from text edit?

I want to read a large text files and not to kill CPU so I need to load text in small chunks
