Function Documentation

create_error()

static std::string sdl::create_error ( const std::string &  operation, const bool  use_sdl_error  )

static

Definition at line 23 of file exception.cpp.

get_mods()

unsigned sdl::get_mods

(

)

Returns a bitmask of active modifier keys (ctrl, shift, alt, gui).

Unused modifier keys (caps lock, scroll lock, num lock, AltGr) are filtered out and will always be unset.

Left and right keys are not distinguished. If either is detected, both will be set. For example if only left shift is down, both KMOD_LSHIFT and KMOD_RSHIFT will be set in the returned bitmask.

Returns

A bitmask of SDL_Keymod values representing the active state.
