determine if a user has clicked in a window header/title bar?

is there a clean way to determine if a user has clicked in a window header/title bar?

for background, I'm laying out all of windows using nk_layout_space_xxx with values fed by a cassowary constraint solver.

I see where we're calculating header bounds in nk_panel_begin, and I can shadow that logic or cache it off internal to the window, but I'd prefer a utility method that indicated the title was clicked or way to get the exact bounds of the header?

any preferred suggestion?

thanks.

Start by reading nk_panel_begin and the existing nk_layout_space_xxx usage described in the issue, then trace how header bounds and click input are handled. Compare exposing the header bounds with reporting title-bar clicks, and define which API behavior would satisfy the request; no test or specific implementation location is named.
