Setting Dynamic Back ground image on QTableWidget

[dholliday]

Hi There.

Simple question, but I can't figure out how to make it work.
I want to set an image to be always at the bottom right hand corner of my QTableWidget. I've got this to work by setting the following:

myTableWidget->viewport()->setStyleSheet("background-image: url(:/images/myimage.png); background-repeat:no-repeat;background-attachment:fixed;background-position:bottom right;");

myTableWidget->viewport()->setStyleSheet("background-image: url(:/images/myimage.png); background-repeat:no-repeat;background-attachment:fixed;background-position:bottom right;");

To copy to clipboard, switch view to plain text mode 

This work exactly as I wanted. However I've now come to enhance some features and my image now needs to be dynamic. I have a class that return a QPixmap with the appropriate image. I don't want to save the physical file to a harddrive because I may have multiple version of the same control open at the same time all requireing different images, and I don't want to clog up the users hard drive with temporary images.

I've tried lots of different variation of the following all with little success.

QPalette pal = myTableWidget->viewport()->palette();
pal.setBrush( myTableWidget->viewport()->backgroundRole(), QBrush( QPixmap(":/images/myimage.png")) );
myTableWidget->viewport()->setPalette( pal );

QPalette pal = myTableWidget->viewport()->palette();
pal.setBrush( myTableWidget->viewport()->backgroundRole(), QBrush( QPixmap(":/images/myimage.png")) );
myTableWidget->viewport()->setPalette( pal );

To copy to clipboard, switch view to plain text mode 

This sort of works, but it's on the top right and when I scroll the table columns from left to right the image breaks up, also the image scrolls and is not fixed to possition.

Anyhelp would be apprechiated.
