How to make QTextEdit to look like QLabel?

[pielas]

Hi, how to make QTextEdit to look like QLabel? I mean to disable text selection, hide borders and set background like QMainWindow background. I've tried to set flags QFrame::StyledPanel and QFrame::Plain but background hasn't changed(remained white). So what should I do to do that?

See QTextEdit::textInteractionFlags and QWidget::setBackgroundRole() or QWidget::palette.

textInteractionFlags works but I've tried every ColorRole and nothing has changed with background under text.

Is it a theoretical question or practical? If the last - just use QLabel ...

[pielas]

It's practical question. I would use QLabel but QTextEdit have built-in scroll bars and I want to use them.

Use QScrollArea with QLabel inside it

Well I don't know how your roles for your widget are defines. So did you try to use the widgets palette with Qt::transparent? And also play with QWidget::autoFillBackground.

I would also advise to use QTextBrowser instead of QTextEdit if you only want to display something.

What are the reasons for choosing QTextBrowser? It inherits QTextEdit and if you only want to display something, QTextEdit with QTextEdit::setReadOnly() should be the lightest class to do so? (Without hyperlinks). Or do I miss something?

No, in general you are right. But QTextBrowser would be a direct equivalent of QLabel in the text document world including the hyperlinks which are available in QLabel as well. If one doesn't need hyperlinks then indeed QTextEdit will be a bit lighter.

Ah, ok, I see.

I couldn't change this background to other than black or white so I decided to use QScrollArea with QLabel. Thanks for replies.

[wysota]

I don't have any problems with changing the background colour of QTextEdit...

[pielas]

What option do you use to set that? My edit still looks like that:

[wysota]

Mine looks like this:

It's probably something wrong with my system becouse your form in KUIViewer looks like this:


//edit: oh it's my fault I haven't seen that this is fixed background color.

//edit2: Yeah it works. I've wrotten this:

QPalette palette = edit->palette();
palette.setColor(QPalette::Base, palette.color(QPalette::Window));
edit->setPalette(palette);

QPalette palette = edit->palette();
palette.setColor(QPalette::Base, palette.color(QPalette::Window));
edit->setPalette(palette);

To copy to clipboard, switch view to plain text mode 

[wysota]

You can probably use the transparent colour as well. That's what I wanted to do myself but I couldn't see a way to express it in Designer and I didn't want to do any manual coding.

[pielas]

Yes it works too and It's probably better way than mine. Thanks everybody for help.
