draw_nine_patch

[Shadowblitz16]

Describe the project you are working on

I am trying to extend the control node into a widget class that suits my needs better
However I need to be able to draw a nine patch

Describe the problem or limitation you are having in your project

I don't exactly know how to draw a nine patch and a draw function/method would be nice to have

Describe the feature / enhancement and how it helps to overcome the problem or limitation

It allows people to quickly draw nine patches from any canvas node

Describe how your proposal will work, with code, pseudo-code, mock-ups, and/or diagrams

Idk what the api will looks like but perferablity it would take a rectangle and patch margin and a x and y stretch mode

If this enhancement will not be used often, can it be worked around with a few lines of script?

It would be used in cases built in nodes do not cut it and we need to draw a nine patch

Is there a reason why this should be core and not an add-on in the asset library?

drawing functions are already part of the engine this would just be a addition

This already exists as RenderingServer.canvas_item_add_nine_patch(). This is what NinePatchRect internally calls: https://github.com/godotengine/godot/blob/24cb43a8741c7b10abbbbc77bb6e2bc188662ce0/scene/gui/nine_patch_rect.cpp#L49

This could probably be exposed as a high-level function in CanvasItem, like CanvasItem.draw_multimesh().

In 3.x, use VisualServer instead of RenderingServer.

Wait does this add it or just render it for one frame?

[KoBeWi]

It draws it, just like the drawing functions of CanvasItem.

[Shadowblitz16]

so why is there a api in consistency? is it possible to move or copy it to a Node2D and Control draw function?

[KoBeWi]

so why is there a api in consistency?

It's not inconsistency. There are methods like canvas_item_add_circle() or canvas_item_add_polygon(), which are called internally by CanvasItem. The ninepatch one just wasn't added to CanvasItem and only exists in RenderingServer.

is it possible to move or copy it to a Node2D and Control draw function?

Yes. Not sure why it wasn't done.
