imgui.Begin

imgui.Begin(name: string, open: boolean?, flags: number?): (boolean, boolean)

Starts a window and returns whether its contents need drawing and whether it is still open. Passing open gives the window a close button; feed the second return back in next frame. End must be called whatever the first return says.

Example

lua

local visible, open = imgui.Begin("panel", open, imgui.WindowFlags.NoResize)
