Base Classes

PtWidget <-- PtBasic <-- PtClock

Description

This widget displays a clock in one of three types: analog (with a dial and hands), digital, or LED format. The display is good for general time-keeping but is not very precise. It is updated about every second, and is prone to flickering. You can minimize this annoyance by not using a transparent fill color, by disabling the seconds, and/or by putting the clock in a PtContainer widget.

For detailed information, please refer to PtClock in the Photon documentation.

Instance Variables

clock_face_color

An integer specifying the color of an analog clock face. Default is 0xffffff (white).

clock_face_outline_color

An integer specifying the color of the line around an analog clock face. Default is 0x0 (black).

clock_flags

Flags that define the clock's appearance and behavior. The default is PtCLOCK_TRACK_TIME | Pt_CLOCK_SHOW_SECONDS | Pt_CLOCK_SHOW_NUMBERS.

This instance variable may be a combination of zero or more of the following flags:

Constant	Description
`Pt_CLOCK_TRACK_TIME`	Updates the clock to current time, by the second.
`Pt_CLOCK_SHOW_SECONDS`	Shows the seconds of the time.
`Pt_CLOCK_24_HOUR`	Makes a 24-hour display, instead of 12-hour.
`Pt_CLOCK_SHOW_NUMBERS`	Sets an analog clock to display numbers instead of hands.
`Pt_CLOCK_SHOW_AMPM`	Adds an AM/PM display to digital and LED clocks.
`Pt_CLOCK_PAD_HOURS`	Adds a leading zero to one-digit hour displays in digital and LED clocks.

clock_font

A string specifying the font for numbers on analog clocks, and for the whole display for digital clocks.

clock_hour, clock_minute, clock_second

An integer indicating the current hour, minute, or second setting of the clock, in 24-hour format. The default for each of these is Pt_CLOCK_CURRENT, which sets to system time when the widget is realized.

clock_hour_color, clock_minute_color, clock_second_color

An integer specifying the color for the hour, minute, or second display. The defaults are 0x0 (black), 0x0 , and 0xff0000 (red) respectively.

clock_hour_offset, clock_minute_offset, clock_second_offset

An integer specifying the number of hours, minutes, or seconds to offset the respective field in the display, if desired.

clock_sep1, clock_sep1_color

A string and a number specifying the character and color of the separator between the hours and the minutes on a digital clock. The defaults are 0x0 (black) and ":".

clock_sep2, clock_sep2_color

A string and a number specifying the character and color of the separator between the minutes and the seconds on a digital clock. The defaults are 0x0 (black) and ":".

clock_type

This instance variable specifies the type of clock, and may have one of the following values:

Constant	Description
`Pt_CLOCK_DIGITAL`	The clock has a digital display that uses system fonts.
`Pt_CLOCK_ANALOG`	The clock has an analog display: a dial with hands.
`Pt_CLOCK_LED`	The clock has a display similar to an LED or LCD clock, which can be scaled.

Callbacks

The following callback is associated with this widget:

Callback	Description
`Pt_CB_CLOCK_TIME_CHANGED`	This callback is generated when the time on the clock changes.
