Function Documentation

calculate_overview_dimensions()

void calculate_overview_dimensions

(

)

Called if the map size is know or changes.

Definition at line 357 of file overview_common.cpp.

Referenced by handle_map_info().

flush_dirty_overview()

void flush_dirty_overview

(

)

Redraw the overview if it is "dirty".

This module contains various general - mostly highlevel - functions used throughout the client.

Definition at line 249 of file overview_common.cpp.

gui_to_natural_pos()

void gui_to_natural_pos	(	const struct tileset *	t,
		double *	ntl_x,
		double *	ntl_y,
		int	gui_x,
		int	gui_y
	)

Translate from gui to natural coordinate systems.

This provides natural coordinates as a floating-point value so there is no loss of information in the resulting values.

gui_to_overview_pos()

void gui_to_overview_pos	(	const struct tileset *	t,
		int *	ovr_x,
		int *	ovr_y,
		int	gui_x,
		int	gui_y
	)

Translate from gui to overview coordinate systems.

Definition at line 91 of file overview_common.cpp.

overview_redraw_callback()

void overview_redraw_callback

(

struct option *

option

)

Callback to be called when an overview option is changed.

Definition at line 459 of file overview_common.cpp.

Referenced by init_client_options().

overview_to_map_pos()

void overview_to_map_pos	(	int *	map_x,
		int *	map_y,
		int	overview_x,

Referenced by minimap_view::mousePressEvent().

refresh_overview_canvas()

void refresh_overview_canvas

(

)

Redraw the entire backing store for the overview minimap.
