Detailed Description

Macro Definition Documentation

retrogui_can_focus_ctl

#define retrogui_can_focus_ctl

(

ctl

)

Value:

      (RETROGUI_CTL_TYPE_BUTTON == (ctl)->base.type || \
      RETROGUI_CTL_TYPE_TEXTBOX == (ctl)->base.type || \
      RETROGUI_CTL_TYPE_LISTBOX == (ctl)->base.type)

Determine if a RETROGUI_CTL can hold RETROGUI::focus.

RETROGUI_CTL_TABLE

#define RETROGUI_CTL_TABLE

(

f

)

Value:

   RETROGUI_CTL_TABLE_BASE( f ) \
   f( 6, TEXTBOX, MAUG_MHANDLE text_h; char* text; size_t text_sz; size_t text_sz_max; size_t text_cur; int16_t blink_frames; )

RETROGUI_CTL_TABLE_BASE

#define RETROGUI_CTL_TABLE_BASE

(

f

)

Value:

   f( 0, NONE, void* none; ) \
   f( 1, LISTBOX, struct MDATA_VECTOR list; size_t sel_idx; ) \
   f( 2, BUTTON, MAUG_MHANDLE label_h; char* label; size_t label_sz; int16_t push_frames; uint8_t font_flags; ) \
   f( 3, LABEL, MAUG_MHANDLE label_h; char* label; size_t label_sz; uint8_t font_flags; ) \
   f( 4, IMAGE, retroflat_blit_t image; ssize_t image_cache_id; int16_t instance; retroflat_pxxy_t src_x; retroflat_pxxy_t src_y; ) \
   f( 5, FILLBAR, uint8_t flags; uint16_t cur; uint16_t max; )

Table defining all control types and their specific fields in RETROGUI_CTL.

This table takes a macro as an argument, itself with the argumentS:

Parameters

type_idx	Index passed to RETROGUI_CTL_BASE::type.
struct	Name of the struct under the RETROGUI_CTL union.
fields	Semicolon-separated list of fields for the type struct.

Each such macro defines a new control type.

All entries in this table have corresponding retrogui_redraw_*, retrogui_poll_*, retrogui_init_*, and retrogui_push_* functions which are called internally from retrogui_redraw_ctls(), retrogui_poll_ctls(), retrogui_init_ctl(), and retrogui_push_ctl(), respectively.

RETROGUI_CTL_TABLE_FIELDS

#define RETROGUI_CTL_TABLE_FIELDS	(		idx,
			c_name,
			c_fields
	)

Value:

   struct RETROGUI_CTL_ ## c_name { \
      struct RETROGUI_CTL_BASE base; \
      c_fields \
   };

Creates the corresponding RETROGUI_* structs from ::RETROGUI_CTL_TABLE that populate union RETROGUI_CTL.
