Function Documentation
- Function Description
- This function resets all variables from GSCHEM_TOPLEVEL that are used for net drawing. This function should be called when escaping from a net drawing action or before entering it.

- Function Description
Definition at line 140 of file o_net.c.
- Function Description
- This function checks all connectable objects at a starting point. It determines the best drawing direction for each quadrant of the possible net endpoint.
The directions are stored in the GSCHEM_TOPLEVEL->net_direction variable as a bitfield.
Definition at line 180 of file o_net.c.
- Function Description
- This function calculates the distance to all connectable objects and searches the closest connection point. It searches for pins, nets and busses.
The connection point is stored in GSCHEM_TOPLEVEL->magnetic_wx and GSCHEM_TOPLEVEL->magnetic_wy. If no connection is found. Both variables are set to -1.
Definition at line 303 of file o_net.c.
- Function Description
- Depending on the two rubbernet lines from start to last and from last to second, the 3 coordinates are manipulated to find a way to the magnetic marker.

- Function Description
- If the mouse is moved, this function is called to update the position of the magnetic marker. If the controllkey is pressed the magnetic marker follows the mouse.
Definition at line 498 of file o_net.c.
- Function Description
- This function sets the start point of a new net at the position of the cursor. If we have a visible magnetic marker, we use that instead of the cursor position
Definition at line 521 of file o_net.c.
- Function Description
- This function finishes the drawing of a net. If we have a visible magnetic marker, we use that instead of the current cursor position.
The rubber nets are removed, the nets and cues are drawn and the net is added to the TOPLEVEL structure.
The function returns TRUE if it has drawn a net, FALSE otherwise.
