Hi,

I want to start by thanking about working on experimental immediate mode extension for Slate, SlateIM; I really think this is one of the biggest quality of life improvements. I’ve got it working on 5.5 version and been testing it with great success so far; and I’ve been interested in adding support for extended engine drawers or custom drawers like a SSearchableComboBox, however currently it looks like the existing SlateIM implementation doesn’t seem to make this easy as a lot of the important pieces are placed in the private folders and not marked with API prefixes, and I wanted to ask if there are plans to make it available to implement drawers externally through other plugins.

So far in my limited testing just enabling API access on some classes/structs on the SlateIMManager.h was enough but I’m guessing some additional helper classes like the WidgetScope also might be needed.

Thanks in advance & have a great day.<

Hi Dylan,

That’s great to hear, I don’t have a CL I can share easily, however I updated the plugin with your most recent changes and while doing so tested the minimal set of changes and these are the classes & structs I needed to add SLATEIM_API to get everything working;

In SlateIMManager.h;

  • FRootNode
  • FWidgetActivation
  • FSlateIMManager

And In SlateIMExamples.h (So that I can draw the examples inside another custom widget):

  • FSlateIMTestWidget

Hi,

I do plan on allowing other plugins to implement their own Roots and Widgets, but I don’t have a timeline on when I’d expose everything. Though, if you have a CL that exposes the types/methods you needed to implement custom widgets, I’m open to taking a pull request in the short term.

Thanks,

Dylan
