Here is the call graph for this function:

void o_bus_start	(	GSCHEM_TOPLEVEL *	w_current,
		int	w_x,
		int	w_y
	)

Function Description

This function sets the start point (w_x,w_y) of a new bus in the GSCHEM_TOPLEVEL structure.

The start point is stored in first_wx, first_wy.

Parameters:

[in]	w_current	The GSCHEM_TOPLEVEL object.
[in]	w_x	the x position in world coords
[in]	w_y	the y position in world coords

int o_bus_end	(	GSCHEM_TOPLEVEL *	w_current,
		int	w_x,
		int	w_y
	)

Function Description

This function finishes a net drawing action. The function draws a bus from the point (first_wx,first_wy) to (second_wx,second_wy). Both points are taken from the GSCHEM_TOPLEVEL structure.

The function returns TRUE if a bus object has been created and FALSE if no bus object has been created.

Parameters:

[in]	w_current	The GSCHEM_TOPLEVEL object.
[in]	w_x	(unused)
[in]	w_y	(unused)

Here is the call graph for this function:

void o_bus_motion	(	GSCHEM_TOPLEVEL *	w_current,
		int	w_x,
		int	w_y
	)

Function Description

This function draws a bus rubber from the point (first_wx,first_wy) from the GSCHEM_TOPLEVEL structure to the input parameter (w_x, w_y).

The function stores creates an non-orthogonal bus segment if the CONTROLKEY is pressed. The coordinates of the second rubberbus point is stored as (second_wx,second_wy) in the GSCHEM_TOPLEVEL structure.

Parameters:

[in]	w_current	The GSCHEM_TOPLEVEL object.
[in]	w_x	current x position in world units
[in]	w_y	current y position in world units

Function Description

This function draws a bus segment from the point (first_wx,first_wy) to the point (second_wx,second_wy) from the GSCHEM_TOPLEVEL structure.

The function can be used to draw or erase the rubberbus on the screen.

Parameters:

[in]

w_current

The GSCHEM_TOPLEVEL object
