Background image not visble

[GrahamL]

Hello
I am trying to create am application where the main window shows a 'watermark' as the backgound
Is this possible ?
How would I go about it?

Thanks

Easiest might be to use a style sheet for that.

[utcenter]

Or just reimplement the paint event, create a QBrush with the image and fill the widget rect() with it - it will pattern out nicely.

Thanks for the replies
Both of these methods result in a tiled effect.
What I want to achieve is have a single image

How can I do that

[andre]

You can control the repeating using the background-repeat style sheet property. Or you go utcenter's way of subclassing and just do your own rendering using QPainter::drawImage in the corner you want.

Hi
I have set a background image on my main window by over riding the paintEvent.
However, if I set the background color of the widget the image is no longer visible - what do I need to do in order to be able to set a background color and have a background image?

Thanks

moderators note: I have merged your two topics. Please don't just start new topics on essentially the same issue.

sorry, my apologies

If you re-implement paintEvent you are responsible for painting everything yourself, including background color via something like QPainter::fillRect(). If you want to stick to the default color you can call QWidget::paintEvent() at the top of your reimplemented method and then paint over the image.
