Function Documentation

anim_cursor_cb()

static gboolean anim_cursor_cb ( gpointer  data )

static

This function is used to animate the mouse cursor.

Definition at line 234 of file mapview.c.

dirty_all()

void dirty_all

(

void

)

Mark the entire screen area as "dirty" so that we can flush it later.

Definition at line 456 of file mapview.c.

dirty_rect()

void dirty_rect	(	int	canvas_x,
		int	canvas_y,
		int	pixel_width,
		int	pixel_height
	)

Mark the rectangular region as "dirty" so that we know to flush it later.

Definition at line 447 of file mapview.c.

draw_selection_rectangle()

void draw_selection_rectangle	(	int	canvas_x,
		int	canvas_y,
		int	w,
		int	h
	)

Draws a rectangle with top left corner at (canvas_x, canvas_y), and width 'w' and height 'h'. It is drawn using the 'selection_gc' context, so the pixel combining function is XOR. This means that drawing twice in the same place will restore the image to its original state.

NB: A side effect of this function is to set the 'selection_gc' color to COLOR_MAPVIEW_SELECTION.

Definition at line 752 of file mapview.c.

flush_dirty()

void flush_dirty

(

void

)

Flush all regions that have been previously marked as dirty. See dirty_rect and dirty_all. This function is generally called after we've processed a batch of drawing operations.

Definition at line 468 of file mapview.c.

get_overview_area_dimensions()

void get_overview_area_dimensions	(	int *	width,
		int *	height
	)

Return the maximum dimensions of the area (container widget) for the overview. Due to the fact that the scaling factor is at least 1, the real size could be larger. The calculation in calculate_overview_dimensions() limit it to the smallest possible size.

Definition at line 320 of file mapview.c.

get_overview_window()

struct canvas * get_overview_window

(

void

)

Return a canvas that is the overview window.

Definition at line 340 of file mapview.c.

get_thumb_pixbuf()

GdkPixbuf * get_thumb_pixbuf

(

int

onoff

)

Get sprite for treaty acceptance or rejection.

Definition at line 295 of file mapview.c.

gui_flush()

void gui_flush

(

void

)

Do any necessary synchronization to make sure the screen is up-to-date. The canvas should have already been flushed to screen via flush_dirty - all this function does is make sure the hardware has caught up.

Definition at line 477 of file mapview.c.

Also calls update_unit_pix_label() to update the icons for units on this square.
