TTimeEdit.ValidTimeFormat function

Declaration

function ValidTimeFormat(AFormat: string): Boolean

Arguments

Function result

Returns True if the specified time format is valid for the control.

Description

TTimeEdit requires a time format string that does not include date or interval parts which are not used/allowed in the class instance. ValidTimeFormat examines the characters in AFormat to determine which parts are used.

The return value is False if AFormat contains any format specifier(s) or combination of specifier(s) which are not allowed in the control.

The return value is True if AFormat is a valid time format setting for use in the TimeFormat property.

ValidTimeFormat is called when a new value is assigned to the TimeFormat property, and prevents updates to both TimeFormat and Time if the method returns False.

See TimeFormat for more information about the available format specifiers and their usage.

Use TimeSeparator to specify the separator character used to delimit time parts in the formatted Text.

Added in LCL version 4.0.
