Clock Value Flag Constants

NEW WITH THE APPEARANCE MANAGER

You can pass one or more of these mask constants into the control ('CNTL') resource or in the initialValue parameter of NewControl. The clock control is editable and supports keyboard focus. The little arrows used to allow manipulation of date and time are part of the control, not a separate embedded little arrows control.

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.
