Clock Value Flag Constants
You can use the clock value flag constants to specify behaviors for a clock control. You can pass one or more of these mask constants into the control ('CNTL'
) resource or in the initialValue
parameter of NewControl
. Note that the standard
clock control is editable and supports keyboard focus. Also, the little arrows that allow manipulation of the date and time are part of the control, not a separate embedded little arrows control. The clock value flag constants are available with Appearance Manager 1.0 and later.
enum {
kControlClockNoFlags = 0,
kControlClockIsDisplayOnly = 1,
kControlClockIsLive = 2
};
Constant descriptions
-
kControlClockNoFlags
-
Indicates that clock is editable but does not display the current "live" time.
-
kControlClockIsDisplayOnly
-
When only this bit is set, the clock is not editable. When this bit and the
kControlClockIsLive
bit is set, the clock automatically updates on idle (clock will have the current time).
-
kControlClockIsLive
-
When only this bit is set, the clock automatically updates on idle and any changes to the clock affect the system clock. When this bit and the
kControlClockIsDisplayOnly
bit is set, the clock automatically updates on idle (clock will have the current time), but is not editable.
