WRasterImage don't repaint.
Added by Marcel Tella about 14 years ago
Hi experts!
I've got into a trouble which is being very difficult to solve.
I've created a class called WebImage, this class recieves an image and shows it in the web.
My aim was, I wanted a WImage and a WRasterImage as members of this class. This way I could paint and repaint without having to use WRasterImage.
Just Using WebImage.
The thing is, it doesn't refresh the image, when I modify the WRasterImage, and then reset the WImage with the method .setResource(resource)
The only way it has worked has been just creating a new WRasterImage for each painting, which is a terrible lack of memory, because I'm just doing news, but I'm not doing any delete.
I'm going to attach you my class in a .zip.
How could I face this?
Thank you very much! I really appreciate your help

Dear Marcel,
WImage::setResource(WResource* resource) only has effect if resource is a new pointer.
You can achieve what you intend, by calling WResource::setChanged() on your resource.
Kind regards,
Pieter
