sdl_window_flag(?Flag:atom, ?Value:integer) is nondet

Enumerate the window creation flags. Each flag is a Prolog atom linked to its SDL bit-mask value.

The user-facing flag atoms are:

• fullscreen
• opengl
• occluded
• hidden
• borderless
• resizable
• minimized
• maximized
• mouse_grabbed
• input_focus
• mouse_focus
• external
• high_pixel_density
• mouse_capture
• mouse_relative_mode
• always_on_top
• utility
• keyboard_grabbed
• fill_document
• vulkan
• metal
• transparent
• not_focusable
• input_grabbed -- synonym for mouse_grabbed
• allow_highdpi -- synonym for high_pixel_density Flags requiring a parent window (modal, tooltip, popup_menu) are not exposed.

 sdl_windowpos(?Pos:term, ?Value:integer) is nondet

Special window-position constants. A window position is either one of these atoms or a plain integer pixel offset (validated by the sdl_windowpos type, which accepts both).

 sdl_createwindow(-Handle:blob, +Title:string, +Width:positive_integer, +Height:positive_integer, +Flags:list(sdl_window_flag)) is det

Create a window. Each element of Flags must be one of the atoms enumerated by sdl_window_flag/2.

 sdl_setwindowposition(+Window:blob, +X:sdl_windowpos, +Y:sdl_windowpos) is det
