- MODE COMMANDS
- *************
-
- These commands are used to either set the mode of operation or
- to specify the primary input device.
-
- The commands are:-
-
- SNAP:- Activates the grid such that all subsequent point
- or line manipulations will snap to the grid (i.e.
- terminating at the nearest grid point).
- In SNAP mode, the grid will be automatically displayed
- on redraws.
- If the SNAP mode is selected with the LEFT PUCK button,
- QikDraw will allow the user to define offsets to the
- nearest grid point instead of snapping to the grid point.
- NOSNP:- Deactivates the SNAP option. (DEFAULT)
- KEY-B:- Specifies that the Key-board is to be the primary
- input device.
- PUCK:- Specifies that the PUCK (graphics tablet) is to be
- the primary input device. (DEFAULT)
- FILE:- Specifies that input would be from a file. Currently
- implemented only for SYMBOL EDIT using file containing
- symbol definitions.
- PEN:- Activate or de-activate displays of graphical entities
- specified under various pen numbers.
- The pen numbers are displayed with a "+" sign if active,
- and are displayed with a "-" sign if not.
- If MODE PEN option selected with the central button, the
- pen status for the sub-drawing will be retained on file.
- If selected with the LEFT button, status is current for
- plotting purposes only (not affecting logical presence).
- INTER:- Allowing for INTERfacing to user specified modules.
- (Parametric design).
- *MACR:- Macro Symbols are implemented as the alernate
- selection. All Macro Symbols should have the .MSY
- extension. For more information, consult the sample
- file IBEAM.MSY.
- Normal Selection MACRO (OPAL) not yet implemented.
- DRAW :- Set the drawing mode for dimensions, hatching and fill
- for planes, and display of symbols, symbol reference
- as well as non-graphics attributes.
- Dimensions and hatchings may be suppressed or activated.
- For symbols, the user can request that all symbols (or all
- strings with more than one symbol) are to be displayed
- as a box.
- PEN specifications can be re-assigned.
- Spacing for solid fill can be re-specified.
- Directions of lines may be displayed.
- These MODE DRAW specifications applies to all the sub-
- drawings if a drawing is to be displayed.
- If TRACK mode is on, the program will track and
- display the co-ordinate of the cursor when it is in
- the primary view-port.
- If DRAG mode is on, then the full symbol is displayed
- when moving the symbol. As this feature is implemented
- by redrawing on some systems, it may be wise to turn it
- off to stop long delays. If DRAG is off, then only a box
- representing the symbol is displayed.
- INFO:- Specifying non-graphics information/attributes (NGA).
- NGA's are governed by a control file containing up
- to 120 item name records each followed by a format
- description record (for documentation purpose only).
- Each item of NGA can be up to 240 characters in length.
- User can convert existing symbol strings into NGA.
- If the tertiary menu (for entity selection) is
- selected with the LEFT button, QikDraw numbers
- assigned to entities may be converted into NGA.
- The control file is normally stored in the master
- (e.g. /usr/qikdraw) directory.
