navit_add_layout()

static int navit_add_layout ( struct navit *  this_, struct layout *  layout  )

check if we want to immediately activate this layout. Unfortunately we have concurring conditions about when to activate a layout:

• A layout could bear the "active" property
• A layout's name could match this_->default_layout_name This cannot be fully resolved, as we cannot predict the future, so lets set the last parsed layout active, which either matches default_layout_name or bears the "active" tag, or is the first layout ever parsed.

navit_autozoom()

static void navit_autozoom ( struct navit *  this_, struct coord *  center, int  speed, int  draw  )

static

Automatically adjusts zoom level.

This function automatically adjusts the current zoom level according to the current speed.

Parameters

this_	The navit struct
center	The "immovable" point - i.e. the vehicles position if we're centering on the vehicle
speed	The vehicles speed in meters per second
dir	The direction into which the vehicle moves

navit_block()

int navit_block	(	struct navit *	this_,
		int	block
	)

Blocks or unblocks redraw operations.

The

block 

parameter specifies the operation to carry out:

block > 0 

cancels all draw operations in progress and blocks future operations. It sets flag 1 of the

blocked 

member. If draw operations in progress were canceled, flag 2 is also set.

block = 0 

unblocks redraw operations, resetting

blocked 

to 0. If flag 2 was previously set, indicating that draw operations had been previously canceled, a redraw is triggered.

block < 0 

unblocks redraw operations and forces a redraw. As above,

blocked 

is reset to 0.

Parameters

this_	The navit instance
block	The operation to perform, see description

Returns

true 

if a redraw operation was triggered,

false 

if not

navit_get_cursor_pnt()

Calculates the position of the cursor on the screen.

This method considers padding if supported by the graphics plugin. In that case, the inner rectangle (i.e. screen size minus padding) will be used to center the cursor and to determine cursor offset (as specified in this_->radius).

Parameters

this_	The navit object
p	Receives the screen coordinates for the cursor
keep_orientation	Whether to maintain the current map orientation. If false, the map will be rotated so that the bearing of the vehicle is up.
dir	Receives the new map orientation as requested by screen_orientation (can be NULL)

Returns

Always 1

navit_get_destinations()

int navit_get_destinations	(	struct navit *	this_,

Retrieves destinations from the route.

Prior to calling this method, you may want to retrieve the number of destinations by calling navit_get_destination_count(struct navit *) and assigning a buffer of sufficient capacity.

If the return value equals count, the buffer was either just large enough or too small to hold the entire list of destinations; there is no way to tell from the result which is the case.

If the Navit instance does not have a route, the result is 0.

Parameters

this_	The Navit instance
pc	Pointer to an array of projected coordinates which will receive the destination coordinates
count	Capacity of pc

Returns

The number of destinations stored in pc, never greater than count

navit_ignore_button()

int navit_ignore_button

(

struct navit *

this_

)

Sets a flag indicating that the current button event should be ignored by subsequent handlers.

Calling this function will set the

ignore_button 

member to

true 

and return its previous state. The default handler, navit_handle_button(navit *, int, int, point *, callback *) calls this function just before the actual event handling core and aborts if the result is

true 

. In order to prevent multiple handlers from firing on a single event, custom button click handlers should implement the same logic for events they wish to handle.

If a handler wishes to pass down an event to other handlers, it must abort without calling this function.

Parameters

this_

The navit instance

Returns

true 

if the caller should ignore the button event,

false 

if it should handle it

navit_set_center_cursor()

void navit_set_center_cursor	(	struct navit *	this_,

Recalculates the map view so that the vehicle cursor is visible.

This function recalculates the parameters which control the visible map area, zoom and orientation. The caller is responsible for redrawing the map after the function returns.

If the vehicle supplies a

position_valid 

attribute and it is

attr_position_valid_invalid 

, the map position is not changed.

Parameters

this_	The navit object
autozoom	Whether to set zoom based on current speed. If false, current zoom will be maintained.
keep_orientation	Whether to maintain the current map orientation. If false, the map will be rotated so that the bearing of the vehicle is up.

static void navit_vehicle_update_position ( struct navit *  this_, struct navit_vehicle *  nv  )

Called when the position of a vehicle changes.

This function is called when the position of any configured vehicle changes and triggers all actions that need to happen in response, such as:

• Switching between day and night layout (based on the new position timestamp)
• Updating position, bearing and speed of

  nv 

  with the data of the active vehicle (which may be different from the vehicle reporting the update)
• Invoking callbacks for

  navit 

  's

  attr_position 

  and

  attr_position_coord_geo 

  attributes
• Triggering an update of the vehicle's position on the map and, if needed, an update of the visible map area ad orientation
• Logging a new track point, if enabled
• Updating the position on the route
• Stopping navigation if the destination has been reached

Parameters

this_	The navit object
nv	The navit_vehicle which reported a new position

navit_vehicle_update_status()

static void navit_vehicle_update_status ( struct navit *  this_, struct navit_vehicle *  nv, enum attr_type  type  )

static

Called when a status attribute of a vehicle changes.

This function is called when the

position_fix_type 

,

position_sats_used 

or

position_hdop 

attribute of any configured vehicle changes.

The function checks if

nv 

refers to the active vehicle and if

type 

is one of the above types. If this is the case, it invokes the callback functions for

navit 

's respective attributes.

Future actions that need to happen when one of these three attribute changes for any vehicle should be implemented here.

Parameters

this_	The navit object
nv	The navit_vehicle which reported a new status attribute
type	The type of attribute with has changed
