Detailed Description

Human Interface Device.

Author:: This file, hid.h, was written and is Copyright (c) 2006 DJ Delorie <dj@delorie.com>

The way the HID layer works is that you instantiate a HID device structure, and invoke functions through its members.

Code in the common part of PCB may *not* rely on *anything* other than what's defined in this file.

Code in the HID layers *may* rely on data and functions in the common code (like, board size and such) but it's considered bad form to do so when not needed.

Coordinates are ALWAYS in pcb's default resolution.

Positive X is right, positive Y is down.

Angles are degrees, with 0 being right (positive X) and 90 being up (negative Y).

All zoom, scaling, panning, and conversions are hidden inside the HID layers.

The main structure is at the end of this file.

Data structures passed to the HIDs will be copied if the HID needs to save them.

Data structures retured from the HIDs must not be freed, and may be changed by the HID in response to new information.

typedef struct hid_draw_st HID_DRAW

Definition at line 349 of file hid.h.

typedef struct hid_gc_struct* hidGC

Enumeration Type Documentation

enum EndCapStyle

Like end cap styles.

The cap *always* extends beyond the coordinates given, by half the width of the line.

Beveled ends can used to make octagonal pads by giving the same x,y coordinate twice.

Enumerator:

Trace_Cap	This means we're drawing a trace, which has round caps.
Square_Cap	Square pins or pads.
Round_Cap	Round pins or round-ended pads, thermals.
Beveled_Cap	Octagon pins or bevel-cornered pads.

Definition at line 85 of file hid.h.

enum hids

HID_Label
HID_Integer
HID_Real
HID_String
HID_Boolean
HID_Enum
HID_Mixed
HID_Path
HID_Unit
HID_Coord

Definition at line 233 of file hid.h.

enum LayertypeType

These are layers with direct physical representation, like copper, dye or to be milled paths. Their data can't be derived from other layers or element data.

To add more layer types, add them to the list here and in layerflags.c. Order of entries in both lists must be the same.

Enumerator:

LT_COPPER
LT_SILK
LT_MASK	Complements SL_MASK above.
LT_PASTE	Complements SL_PASTE above.
LT_OUTLINE	Board outline; exists only once.
LT_ROUTE
LT_KEEPOUT
LT_FAB	Complements SL_FAB above.
LT_ASSY	Complements SL_ASSY above.
LT_NOTES
LT_NUM_LAYERTYPES	Must be the last one.

File Watch flags.

Based upon those in dbus/dbus-connection.h.

void hid_expose_callback	(	HID *	hid,
		BoxType *	region,
		void *	item
	)

This function (in the common code) will be called whenever the GUI needs to redraw the screen, print the board, or export a layer.

If item is not NULL, only draw the given item. Item is only non-NULL if the HID was created via show_item.

Each time func is called, it should do the following:

allocate any colors needed, via get_color.

cycle through the layers, calling set_layer for each layer to be drawn, and only drawing elements (all or specified) of desired layers.

Do *not* assume that the hid that is passed is the GUI hid.

This callback is also used for printing and exporting.
