| The validate option allows specification of a validation mechanism. Standard |
| character validation such as \fBnumeric\fR, \fBalphabetic\fR, \fBinteger\fR, |
| \fBhexidecimal\fR, \fBreal\fR, and \fBalphanumeric\fR 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 \fB%\fR characters, then the script will not be |
| executed directly. Instead, a new script will be |
| generated by replacing each \fB%\fR, and the character following |
| it, with information from the entryfield. The replacement |
| depends on the character following the \fB%\fR, as defined in the |
| list below. |
| .TP |
| \fB%c\fR |
| Replaced with the current input character. |
| .TP |
| \fB%P\fR |
| 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. |
| .TP |
| \fB%S\fR |
| Replaced with the current contents of the entryfield prior to the latest |
| keystroke being added. |

| .SH DESCRIPTION |
| .PP |
| The \fBiwidgets::entryfield\fR 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. |
| .DE |
| |
| .SH "METHODS" |
| .PP |
| The \fBiwidgets::entryfield\fR command creates a new Tcl command whose |
| name is \fIpathName\fR. This |
| command may be used to invoke various |
| operations on the widget. It has the following general form: |
| .DS C |
| \fIpathName option \fR?\fIarg arg ...\fR? |
| .DE |
| \fIOption\fR and the \fIarg\fRs |
| determine the exact behavior of the command. The following |
| commands are possible for entryfield widgets: |

| .SH "WIDGET-SPECIFIC METHODS" |
| .TP |
| \fIpathName \fBcget\fR \fIoption\fR |
| Returns the current value of the configuration option given |
| by \fIoption\fR. |
| \fIOption\fR may have any of the values accepted by the \fBiwidgets::entryfield\fR |
| command. |
| .TP |
| \fIpathName \fBchildsite\fR |
| Returns the path name of the child site. |
| .TP |
| \fIpathName \fBclear\fR |
| Clear entry widget |
| .TP |
| \fIpathName\fR \fBconfigure\fR ?\fIoption\fR? ?\fIvalue option value ...\fR? |
| Query or modify the configuration options of the widget. |
| If no \fIoption\fR is specified, returns a list describing all of |
| the available options for \fIpathName\fR (see \fBTk_ConfigureInfo\fR for |
| information on the format of this list). If \fIoption\fR is specified |
| with no \fIvalue\fR, 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 \fIoption\fR is specified). If |
| one or more \fIoption\-value\fR 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. |
| \fIOption\fR may have any of the values accepted by the \fBiwidgets::entryfield\fR |
| command. |
