CEGUI (Crazy Eddie's GUI) Forums

Hi All,

Simple question: I'm wanting to add an area of flat colour to my widget, either over the whole widget or over a specified rectangular area, and can't find any obvious way of doing it other than to stretch a white pixel over the area I want and then modulating that with a color in the <Layer>...

Seems like there should be an obvious way to just say "make this area red", but I'm missing it...

edit: Using CEGUI 0.7.5

I think the best way to do this is to modify the LNF to contain a ColourRectProperty or ColourProperty after defining one or multiple connected images (or a white 1pixel dummy texture image).
You can address it using a variable, e.g.:

and on top of your file you can use a PropertyDefinition, which also allows you to address this via setProperty in runtime:


The way CEGUI renders its widgets always uses texture+colour. Unfortunately we do not currently offer a way to just render a rectangular coloured area. Obviously, it would also need to have its dimensions defined in some way.
Either way, if you want to add this feature feel free to try and add this to falagard and create a pull request for us on mercurial so we can review and once it meets our quality standards we will add it.

In any other case use the above workaround.
PS:
You can write a section e.g.:

and then inside a layer you can reference the section and use your ColourProperty or ColourRectProperty:

Wow @Ident, thanks for such a full and well explained reply! - it's at least good to know that I wasn't just missing something obvious

I've started out with just stretching a white pixel where needed, and might go ahead and implement something less hackey soon to clean up. Will post back here if I come up with anything useful.

Thanks again,

Any code snippets of your solution will be well appreciated and might also help other users in the future.
