Name: |
validate |
|||
|
Class: |
Command |
|||
|
Command-Line Switch: |
-validate |
The validate option allows specification of a validation mechanism. Standard character validation such as numeric, alphabetic, integer, hexidecimal, real, and alphanumeric can be handled through the use of keywords. Should more extensive validation be necessary, the value may contain the name of a command script. The script should return a boolean value. True for valid, false for invalid. If false is returned, then the procedure associated with the invalid option will be invoked. If the validation script contains any % characters, then the script will not be executed directly. Instead, a new script will be generated by replacing each %, and the character following it, with information from the entryfield. The replacement depends on the character following the %, as defined in the list below.
|
%c |
Replaced with the current input character. | ||
|
%P |
Replaced with the contents of the entryfield modified to include the latest keystoke. This is equivalent to peeking at the future contents, enabling rejection prior to the update. | ||
|
%S |
Replaced with the current contents of the entryfield prior to the latest keystroke being added. | ||
|
%W |
Replaced with the entryfield widget pathname. |
______________________________________________________________________________
The entryfield command creates an enhanced text entry widget with an optional associated label. Addtional options support validation and establishing a upper limit on the number of characters which may be entered in the field.
The entryfield command creates a new Tcl command whose name is pathName. This command may be used to invoke various operations on the widget. It has the following general form: pathName option ?arg arg ...? Option and the args determine the exact behavior of the command. The following commands are possible for entryfield widgets:
delete get icursor index
|
insert |
scan |
selection |
xview |
See the "entry" manual entry for details on the associated methods.
pathName cget option
Returns the current value of the configuration option given by option. Option may have any of the values accepted by the entryfield command.
pathName childsite
Returns the path name of the child site.
pathName clear
Clear entry widget
pathName configure ?option? ?value option value ...?
Query or modify the configuration options of the widget. If no option is specified, returns a list describing all of the available options for pathName (see Tk_ConfigureInfo for information on the format of this list). If option is specified with no value, then the command returns a list describing the one named option (this list will be identical to the corresponding sublist of the value returned if no option is specified). If one or more option−value pairs are specified, then the command modifies the given widget option(s) to have the given value(s); in this case the command returns an empty string. Option may have any of the values accepted by the entryfield command.
