-TimeCtrl provides a multi-cell control that allows manipulation of a time -value. It supports 12 or 24 hour format, and you can use wxDateTime or mxDateTime -to get/set values from the control. -

-Left/right/tab keys to switch cells within a TimeCtrl, and the up/down arrows act -like a spin control. TimeCtrl also allows for an actual spin button to be attached -to the control, so that it acts like the up/down arrow keys. -

-The ! or c key sets the value of the control to the current time. -

-Here's the API for TimeCtrl: -

-    TimeCtrl(
-         parent, id = -1,
-         value = '12:00:00 AM',
-         pos = wx.DefaultPosition,
-         size = wx.DefaultSize,
-         style = wxTE_PROCESS_TAB,
-         validator = wx.DefaultValidator,
-         name = "time",
-         format = 'HHMMSS',         
-         fmt24hr = False,
-         displaySeconds = True,
-         spinButton = None,
-         min = None,
-         max = None,
-         limited = None,
-         oob_color = "Yellow"
-)
-
- -
-
-
-
EVT_TIMEUPDATE(win, id, func) -
func is fired whenever the value of the control changes. -
-
-
SetValue(time_string | wxDateTime | wxTimeSpan | mx.DateTime | mx.DateTimeDelta) -
Sets the value of the control to a particular time, given a valid -value; raises ValueError on invalid value. -NOTE: This will only allow mx.DateTime or mx.DateTimeDelta if mx.DateTime -was successfully imported by the class module. -
-
GetValue(as_wxDateTime = False, as_mxDateTime = False, as_wxTimeSpan=False, as mxDateTimeDelta=False) -
Retrieves the value of the time from the control. By default this is -returned as a string, unless one of the other arguments is set; args are -searched in the order listed; only one value will be returned. -
-
GetWxDateTime(value=None) -
When called without arguments, retrieves the value of the control, and applies -it to the wxDateTimeFromHMS() constructor, and returns the resulting value. -The date portion will always be set to Jan 1, 1970. This form is the same -as GetValue(as_wxDateTime=True). GetWxDateTime can also be called with any of the -other valid time formats settable with SetValue, to regularize it to a single -wxDateTime form. The function will raise ValueError on an unconvertable argument. -
-
GetMxDateTime() -
Retrieves the value of the control and applies it to the DateTime.Time() -constructor,and returns the resulting value. (The date portion will always be -set to Jan 1, 1970.) (Same as GetValue(as_wxDateTime=True); provided for backward -compatibility with previous release.) -
-
-
BindSpinButton(SpinBtton) -
Binds an externally created spin button to the control, so that up/down spin -events change the active cell or selection in the control (in addition to the -up/down cursor keys.) (This is primarily to allow you to create a "standard" -interface to time controls, as seen in Windows.) -
-
-
SetMin(min=None) -
Sets the expected minimum value, or lower bound, of the control. -(The lower bound will only be enforced if the control is -configured to limit its values to the set bounds.) -If a value of None is provided, then the control will have -explicit lower bound. If the value specified is greater than -the current lower bound, then the function returns False and the -lower bound will not change from its current setting. On success, -the function returns True. Even if set, if there is no corresponding -upper bound, the control will behave as if it is unbounded. -
If successful and the current value is outside the -new bounds, if the control is limited the value will be -automatically adjusted to the nearest bound; if not limited, -the background of the control will be colored with the current -out-of-bounds color. -
-
GetMin(as_string=False) -
Gets the current lower bound value for the control, returning -None, if not set, or a wxDateTime, unless the as_string parameter -is set to True, at which point it will return the string -representation of the lower bound. -
-
-
SetMax(max=None) -
Sets the expected maximum value, or upper bound, of the control. -(The upper bound will only be enforced if the control is -configured to limit its values to the set bounds.) -If a value of None is provided, then the control will -have no explicit upper bound. If the value specified is less -than the current lower bound, then the function returns False and -the maximum will not change from its current setting. On success, -the function returns True. Even if set, if there is no corresponding -lower bound, the control will behave as if it is unbounded. -
If successful and the current value is outside the -new bounds, if the control is limited the value will be -automatically adjusted to the nearest bound; if not limited, -the background of the control will be colored with the current -out-of-bounds color. -
-
GetMax(as_string = False) -
Gets the current upper bound value for the control, returning -None, if not set, or a wxDateTime, unless the as_string parameter -is set to True, at which point it will return the string -representation of the lower bound. - -
-
-
SetBounds(min=None,max=None) -
This function is a convenience function for setting the min and max -values at the same time. The function only applies the maximum bound -if setting the minimum bound is successful, and returns True -only if both operations succeed. Note: leaving out an argument -will remove the corresponding bound, and result in the behavior of -an unbounded control. -
-
GetBounds(as_string = False) -
This function returns a two-tuple (min,max), indicating the -current bounds of the control. Each value can be None if -that bound is not set. The values will otherwise be wxDateTimes -unless the as_string argument is set to True, at which point they -will be returned as string representations of the bounds. -
-
-
IsInBounds(value=None) -
Returns True if no value is specified and the current value -of the control falls within the current bounds. This function can also -be called with a value to see if that value would fall within the current -bounds of the given control. It will raise ValueError if the value -specified is not a wxDateTime, mxDateTime (if available) or parsable string. -
-
-
IsValid(value) -
Returns Trueif specified value is a legal time value and -falls within the current bounds of the given control. -
-
-
SetLimited(bool) -
If called with a value of True, this function will cause the control -to limit the value to fall within the bounds currently specified. -(Provided both bounds have been set.) -If the control's value currently exceeds the bounds, it will then -be set to the nearest bound. -If called with a value of False, this function will disable value -limiting, but coloring of out-of-bounds values will still take -place if bounds have been set for the control. -
IsLimited() -
Returns True if the control is currently limiting the -value to fall within the current bounds. -
