Hi folks, suppose you having a visual UI editing tool, where you can place morphs/controls and define their position(s). I have a model in mind, where coordinates can be defined by formal description, i.e. morph left: morph parent left + some offset morph width: morph parent width / 2 etc. but i wonder, in what way such relations can be represented by UI editor/design tool. I want that user could easily specify following: suppose i placing a button in form, and say that its corner (bottom/right) should be aligned to its parent corner, with some negative offset (-5 @ -5). And button width/height should be calculated by taking a button label text width & height. So, user by specifying two ordinates - corner and width & height, is fully describing a button visual layout. The problem is that button's label is submorph, and i not sure how to formally encode such relation i.e. parent width & height (or any other parent coordinate) depends on its submorph's fixed width/height. -- Best regards, Igor Stasenko AKA sig.
