So this is just a thought…
My plug-in is also a host and has a toolbar which is minimally 410 pixels wide – I found that I need to handle scalable plug-ins different to non-scalable plug-ins when placing them inside my DocumentWindow if they’re less wide than my toolbar’s minimum width.
I noticed this when I got a report from one of my testers when he inserted Cytomic’s The Glue… and it’s the only fully scalable plug-in I’ve seen.
I know we have isResizable() but The Glue returns false for that… and there’s a difference between scalable vs. resizable… for scalable I resize the editor proportionally.
Cheers,
