t_object* patcherview_findpatcherview	(	int	x,
		int	y
	)

Find a patcherview at the given screen coords.

Parameters:

	x	The horizontal coordinate at which to find a patcherview.
	y	The vertical coordinate at which to find a patcherview.

Returns:

A pointer to the patcherview at the specified location, or NULL if no patcherview exists at that location.

t_object* patcherview_get_jgraphics

(

t_object *

pv

)

Given a patcherview, return the t_jgraphics context for that view.

Parameters:

pv

The patcherview instance.

Returns:

The t_jgraphics context for the view.

char patcherview_get_locked

(

t_object *

p

)

Find out if a patcherview is locked.

Parameters:

p

The patcherview instance whose attribute value will be fetched.

Returns:

Returns 0 if unlocked, otherwise returns non-zero.

t_object* patcherview_get_nextview

(

t_object *

pv

)

Given a patcherview, find the next patcherview.

The views of a patcher are maintained internally as a t_linklist, and so the views can be traversed should you need to perform operations on all of a patcher's patcherviews.

Parameters:

pv

The patcherview instance from which to find the next patcherview.

Returns:

The next patcherview in the list, or NULL if the patcherview passed in pv is the tail.

t_object* patcherview_get_patcher

(

t_object *

pv

)

Given a patcherview, return its patcher.

Parameters:

pv

The patcherview instance for which to fetch the patcher.

Returns:

The patcher.

char patcherview_get_presentation

(

t_object *

pv

)

Find out if a patcherview is a presentation view.

Parameters:

pv

The patcherview instance whose attribute value will be fetched.

Returns:

Returns 0 if the view is not a presentation view, otherwise returns non-zero.

t_max_err patcherview_get_rect	(	t_object *	pv,
		t_rect *	pr
	)

Get the value of the rect attribute for a patcherview.

Parameters:

	pv	The patcherview instance whose attribute value will be fetched.
	pr	The address of a valid t_rect struct, whose contents will be filled upon return.

Returns:

An error code.

char patcherview_get_visible

(

t_object *

pv

)

Query a patcherview to determine whether it is visible.

Parameters:

pv

The patcherview instance to query.

Returns:

Returns zero if the patcherview is invisible, otherwise returns non-zero.

double patcherview_get_zoomfactor

(

t_object *

pv

)

Fetch the zoom-factor of a patcherview.

Parameters:

pv

The patcherview instance whose attribute value will be fetched.

Returns:

The factor by which the view is zoomed.

t_max_err patcherview_set_locked	(	t_object *	p,
		char	c
	)

Lock or unlock a patcherview.

Parameters:

	p	The patcherview instance whose attribute value will be set.
