Background color for a label and goup box
Message 1 in thread
Hi,
I wanted to change the background color of a label, I tried
label->setPalette(QPalette(QColor(100,100,0),QColor(255,0,0))); but it
did'nt work.
Also, is there a way to change the background color of the area in a group
box (which has some widgets)??
Another question is how to put hyperlinks in a label, I looked into the
QTextBrowser but it din find any good documentation on this. Please let me
know if you are familiar with solving any of these.
Thanks,
-Subir

Check QPalette::setColor() functions.
For example to set the background color of a qlabel:
QPalette Pal(TheLabel->palette());
Pal.setColor(QPalette::Window, Qt::blue);
TheLabel->setPalette(Pal);

QApplication MainApplication (argc, argv);
QPalette mainAppPalette ;
mainAppPalette.setColor
(QPalette::Normal, QPalette::Background, Qt::white);
mainApplication.setPalette(main_palette);
and then adding widgets with their layouts. Is it because my application is
always white, so i am not able to add colors to widgets ?? Am i doing
something wrong here??

I've never tried setting this via the application but my
example should have included:
TheLabel->setAutoFillBackground(true)

Pretty much the same way. The "trick" is to know which roles
are required. For example, QPalette::Window will take care
of the background of the group box. QPalette::Button will
take care of any buttons in it. QPalette::Base is for text
widgets background etc.
Also, there's another setColor that takes a color group and a
color role.
Look at the docs for QPalette. Qt Assistant if pretty clear
on this.

Sorry I did a reply to u rather than to the mailing list....oops
Groupbox worked looks like group box also requires the
setAutoFillBackground(true)
to be called.
My last question (hopefully for the day) is on hyperlinks. How can I use
hyperlinks in labels, that open in the current browser window on click, I
looked into QTextBrowser but that din help. Let me know if you know abt this
Thanks

No problem. It should have bounced as my reply to

I think so.

Sorry, I can't help you there.
BTW, would you mind posting in plain text?
I seem to have to reformat your posts to reply
to them. I'm not sure what the group guidelines
are here though. It may also be that I'm using
OE for a newsreader.
