Changing Widget Attribute Values

Three ways to change attribute values using the CONTROL command are:

·	You can change an attribute value with a single CONTROL statement. For example:

CONTROL @Meter;SET("VALUE":22)

·	You can also change multiple attribute values with multiple CONTROL statements.

For example:

CONTROL @Bars;SET("BACKGROUND":5)

CONTROL @Bars;SET("SHOW LIMITS":0)

CONTROL @Bars;SET("VALUE":44)

·	You can also change multiple attribute values with a single CONTROL statement.

For example:

CONTROL @Bars;SET("BACKGROUND":5,"SHOW LIMITS":0,"VALUE":44)

Example: Changing Widget Attributes

For example, for a METER widget you can change the value of the common attribute

BACKGROUND using the ASSIGN command as follows, where "2" sets the background

color to red:

10 ASSIGN @Meter TO WIDGET "METER";SET ("BACKGROUND":2)

20 LOOP

30 END LOOP

40 END

Or if you prefer, the BACKGROUND attribute may be SET with the CONTROL statement:

10 ASSIGN @Meter TO WIDGET "METER"

20 CONTROL @Meter;SET ("BACKGROUND":2)

30 LOOP

40 END LOOP

50 END
