| .SH DESCRIPTION |
| .PP |
| The \fBiwidgets::optionmenu\fR command creates an option menu widget with options |
| to manage it. An option menu displays a frame containing a label and a button. |
| A pop-up menu will allow for the value of the button to change. |
| |
| .SH "METHODS" |
| .PP |
| The \fBiwidgets::optionmenu\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 |
| \fIpathName option \fR?\fIarg arg ...\fR? |
| .DE |
| \fIOption\fR and the \fIarg\fRs |
| determine the exact behavior of the command. |
| .PP |
| Many of the widget commands for an optionmenu take as one argument an |
| indicator of which entry of the option menu to operate on. These |
| indicators are called \fIindex\fRes and may be specified in |
| any of the following forms: |
| .TP 12 |
| \fInumber\fR |
| Specifies the entry numerically, where 0 corresponds |
| to the top-most entry of the option menu, 1 to the entry below it, and |
| so on. |
| .TP 12 |
| \fBend\fR |
| Indicates the bottommost entry in the menu. If there are no |
| entries in the menu then -1 is returned. |
| .TP 12 |
| \fBselect\fR |
| Returns the numerical index of the currently selected option menu entry. |
| If no entries exist in the menu, then -1 is returned. |
| .TP 12 |
| \fIpattern\fR |
| If the index doesn't satisfy one of the above forms then this |
| form is used. \fIPattern\fR is pattern-matched against the label of |
| each entry in the option menu, in order from the top down, until a |
| matching entry is found. The rules of \fBTcl_StringMatch\fR |
| are used. |
| .PP |
| The following widget commands are possible for optionmenu 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::optionmenu\fR |
| command. |
| .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::optionmenu\fR |
| command. |
| .TP |
| \fIpathName \fBdelete \fIfirst\fR ?\fIlast\fR? |
| Delete all of the option menu entries between \fIfirst\fR and |
| \fIlast\fR inclusive. If \fIlast\fR is omitted then it defaults |
| to \fIfirst\fR. |
| .TP |
| \fIpathName \fBdisable \fIindex\fR |
| Disable the option menu entry specified by \fIindex\fR. |
| Disabling a menu item will prevent the user from being able to select |
| this item from the menu. This only effects the state of the item |
| in the menu, in other words, should the item be the currently |
| selected item, the programmer is responsible for determining this condition |
| and taking appropriate action. |
| .TP |
| \fIpathName \fBenable \fIindex\fR |
| Enable the option menu entry specified by \fIindex\fR. |
| Enabling a menu item allows the user to select this item from the menu. |
| .TP |
| \fIpathName \fBget\fR ?\fIfirst\fR? ?\fIlast\fR? |
| If no arguments are specified, this operation returns the currently |
| selected option menu item. Otherwise, it returns the name of the |
| option at index \fIfirst\fR, or a range of options between \fIfirst\fR |
| and \fIlast\fR. |
| .TP |
| \fIpathName \fBindex \fIindex\fR |
| Returns the numerical index corresponding to \fIindex\fR. |
| .TP |
| \fIpathName \fBinsert \fIindex string\fR ?\fIstring\fR? |
| Insert an item, or list of items, into the menu at location \fIindex\fR. |
| .TP |
| \fIpathName \fBselect \fIindex\fR |
| Select an item from the option menu to be displayed as the currently |
| selected item. |
| .TP |
| \fIpathName \fBsort \fImode\fR |
| Sort the current menu in either \fBascending\fR, or \fBdescending\fR order. |
| The values \fBincreasing\fR, or \fBdecreasing\fR are also accepted. |
