Since the Agar window system as well as various Agar widgets also need to change the cursor, this interface should always be used as opposed to platform-specific APIs or .Xr SDL_SetCursor 3 in SDL mode. .Pp The following built-in cursors are currently defined: .Bd -literal enum { AG_FILL_CURSOR, AG_ERASE_CURSOR, AG_PICK_CURSOR, AG_HRESIZE_CURSOR, AG_VRESIZE_CURSOR, AG_LRDIAG_CURSOR, AG_LLDIAG_CURSOR, AG_TEXT_CURSOR, AG_LAST_CURSOR }; .Ed .Sh INTERFACE .nr nS 1 .Ft "void" .Fn AG_SetCursor "int CursorID" .Pp .Ft "void" .Fn AG_UnsetCursor "void" .Pp .nr nS 0 The .Fn AG_SetCursor function changes to the specified cursor shape. The change does not take effect until the end of the current event processing loop. .Pp .Fn AG_UnsetCursor changes the cursor shape back to the default. .Sh SEE ALSO .Xr AG_Intro 3 , .Xr AG_Widget 3 , .Xr AG_Window 3 .Sh HISTORY The .Nm interface first appeared in Agar 1.0.
