Custom Graphical Elements? about gxui HOT 1 CLOSED

Is it possible for a client to design their own widget, add it to a layout, and have it rendered?

Yes, completely. There's really nothing special about the mixin implementations, but I completely understand that the whole structure is really confusing. We're thinking about how we can clean this lot up, and make it more idiomatic.

To very briefly describe the current layout:

• The top level is the theme. This is really just a factory for a number of control types that implement the interfaces in the GXUI root. The theme can tweak the control's colors and styling by changing fields and overriding some of methods of the mixins.
• The mixins directory holds full, un-styled implementations of the various controls. They usually 'derive' from one of the types in the base package.
• The mixins\base package provides the bulk of the implementation for Control and Container types. They are formed from pulling together a bunch of parts.
• The mixins\parts package holds partial implementations of controls. i.e. Layoutable implements the SetMargin, Margin, Bounds, Layout, and Relayout methods the way most of controls would want. You can cherry-pick these parts into your new control to remove boilerplate code.

If it's possible, this might make for a good, simple example.

I agree more samples are usually good, but I'm wary of giving examples at this stage for things that are very likely to significantly change. I don't think anyone is happy with the way Component are currently built (the whole mixin and FooOuter stuff are like hammering a square-peg in a round hole). If we can sort this out, then I'm more than happy to create step-by-step tutorials.

If you'd like any more information on any of this, please ask away. The more information I can share, the higher chance there is that someone can offer a far better and cleaner approach to solve the same problems. :)
