Glossary A B C DF G H I K LM N P R S T UVWXY PEN_TYPE
Type Constant Return Value Integer Description The name of a pen property that determines whether the current shape (either a POINT or a LINE) is drawn or erased. Possible contents of this property include SET and UNSET. PEN_TYPE is initialized to SET by Initialize_GUI. Usage Set_Property(GUI_PEN, PEN_TYPE, SET);
Library library.c
PLOT
Type Constant Return Value Integer Description The name of an object type used to create a new plot object. New plot objects have a width of 120 pixels, a height of 120 pixels, and a buffer size for its data of 240 bytes. Plot objects can be resized using the Set_Property method along with the WIDTH_IN_PIXELS, HEIGHT_IN_PIXELS, or BUFFER_SIZE properties. Data is added to a plot buffer using the Add_Data method. The data is rendered onto a screen from the buffer when Refresh is called. Usage plotVoltage = New_Object( PLOT );
Library library.c
POINT
Type Constant Return Value Long Description The name of a value of the SHAPE property of the GUI_PEN object. When the SHAPE property of the GUI_PEN object is set to POINT, the Draw method draws a point or single pixel at the specified x and y location. Usage Set_Property(GUI_PEN, SHAPE, POINT);
Library library.c
See Also LINE PRESS_EVENT
Type Constant Return Value Long Description The name of a value of a keypad property KEY_EVENT and PRIOR_KEY_EVENT that indicates a user has just pressed a key on the keypad. Usage If(Get_Property(GUI_KEYPAD0, KEY_EVENT)==PRESS_EVENT) { printf(“The last event was a press event.\n”); }
Library library.c
See Also HOLD_EVENT, RELEASE_EVENT PRESS_EVENT_PROCEDURE
Type Constant Return Value Integer Description The name of an action key property that contains the xcfa (extended code field address) of a user defined press event procedure. The press event procedure is called each time the action key is pressed. Press event procedures can not take or return any parameters, but they can modify variables. The PRESS_EVENT_PROCEDURE property is uninitialized when an action key is instantiated. Usage Set_Property( actionkeyStop, PRESS_EVENT_PROCEDURE, (long) stop_process_ptr )
Library library.c
See Also HOLD_EVENT_PROCEDURE, RELEASE_EVENT_PROCEDURE PRESS_NUMBER
Type Constant Return Value Integer Description The name of a read only keypad property that contains the number of times the current data entry key has been pressed. The PRESS_NUMBER, along with the SHIFT_STATE (SHIFT_UP, SHIFT_DOWN, or SHIFT_NEUTRAL) and KEY_POSITION (0 to 15 or 20 to 34) determines the KEY_CODE of an overloaded data entry key. Usage pressnum = Get_Property(GUI_KEYPAD0, PRESS_NUMBER);
Library library.c
See Also KEY_CODE, KEY_POSITION, PRIOR_KEY_CODE, SHIFT_STATE PRIOR_KEY_CODE
Type Constant Return Value Integer Description The name of a read only keypad property that contains the key code from the previously pressed data entry key. The key code is based on the SHIFT_STATE (SHIFT_UP, SHIFT_DOWN, or SHIFT_NEUTRAL), KEY_POSITION (0 to 15 or 20 to 34), and PRESS_NUMBER for an overloaded data entry key. Valid key codes are from 1 to 255. The key code is a reference to a glyph of a font that is rendered into a textbox and shown on the display. For examle, key code 65 refers to the glyph of an upper case A where as key code 247 refers to the glyph of a divide sign in the default font. Usage oldkeycode = Get_Property(GUI_KEYPAD0, PRIOR_KEY_CODE);
Library library.c
See Also KEY_CODE, KEY_POSITION, PRESS_NUMBER, SHIFT_STATE PRIOR_KEY_EVENT
Type Constant Return Value Integer Description The name of a read only keypad property that contains the previous keypad event. Valid keypad events are PRESS_EVENT, HOLD_EVENT, RELEASE_EVENT, and NO_EVENT. Usage oldevent = Get_Property(GUI_KEYPAD0, PRIOR_KEY_EVENT);
Library library.c
See Also KEY_EVENT, PRESS_EVENT, HOLD_EVENT, RELEASE_EVENT, NO_EVENT PRIOR_KEY_POS
Type Constant Return Value Integer Description The name of a read only keypad property that contains the position of the previously pressed key. Valid key positions are from 0 to 15 and 20 to 34 which correspond to the phyical location of the keys on the keypad as shown in the table for Insert_Key. Usage oldpos = Get_Property(GUI_KEYPAD0, PRIOR_KEY_POS);
Library library.c
See Also Insert_Key, KEY_POSITION PRIOR_KEY_TYPE
Type Constant Return Value Integer Description The name of a read only keypad property that contains the type of the previously pressed key. Valid key types are ACTION_KEY, DATA_ENTRY_KEY, SHIFT_KEY, and NO_KEY. Usage oldkeytype = Get_Property(GUI_KEYPAD0, PRIOR_KEY_TYPE);
Library library.c
See Also ACTION_KEY, DATA_ENTRY_KEY, SHIFT_KEY, NO_KEY, KEY_TYPE |
