Function Documentation

static gboolean is_object_hit	(	GSCHEM_TOPLEVEL *	w_current,
		OBJECT *	object,
		int	w_x,
		int	w_y,
		int	w_slack
	)		[static]

Function Description

Tests a if a given OBJECT was hit at a given set of coordinates. If an object is not selectable (e.g. it is locked), or it is invisible and not being rendered, this function will return FALSE.

Parameters:

[in]	w_current	The GSCHEM_TOPLEVEL object.
[in]	object	The OBJECT being hit-tested.
[in]	w_x	The X coordinate to test (in world coords).
[in]	w_y	The Y coordinate to test (in world coords).
[in]	w_slack	The slack applied to the hit-test.

Returns:

TRUE if the OBJECT was hit, otherwise FALSE.

static gboolean find_single_object	(	GSCHEM_TOPLEVEL *	w_current,
		OBJECT *	object,
		int	w_x,
		int	w_y,
		int	w_slack,
		int	change_selection
	)		[static]

Function Description

Tests a if a given OBJECT was hit at a given set of coordinates. If so, processes selection changes as appropriate for the object and passed flag. Saves a pointer to the found object so future find operations resume after this object.

Parameters:

[in]	w_current	The GSCHEM_TOPLEVEL object.
[in]	object	The OBJECT being hit-tested.
[in]	w_x	The X coordinate to test (in world coords).
[in]	w_y	The Y coordinate to test (in world coords).
[in]	w_slack	The slack applied to the hit-test.
[in]	change_selection	Whether to select the found object or not.

Returns:

TRUE if the OBJECT was hit, otherwise FALSE.

gboolean o_find_object	(	GSCHEM_TOPLEVEL *	w_current,
		int	w_x,
		int	w_y,
		gboolean	change_selection
	)

Function Description

Tests for OBJECTS hit at a given set of coordinates. If change_selection is TRUE, it updates the page's selection.

Find operations resume searching after the last object which was found, so multiple find operations at the same point will cycle through any objects on top of each other at this location.

Parameters:

[in]	w_current	The GSCHEM_TOPLEVEL object.
[in]	w_x	The X coordinate to test (in world coords).
[in]	w_y	The Y coordinate to test (in world coords).
[in]	change_selection	Whether to select the found object or not.

Returns:

TRUE if the object was hit at the given coordinates, otherwise FALSE.
