| 15 | # ::tk_optionMenu -- | |
| 16 | # This procedure creates an option button named $w and an associated | |
| 17 | # menu. Together they provide the functionality of Motif option menus: | |
| 18 | # they can be used to select one of many values, and the current value | |
| 19 | # appears in the global variable varName, as well as in the text of | |
| 20 | # the option menubutton. The name of the menu is returned as the | |
| 21 | # procedure's result, so that the caller can use it to change configuration | |
| 22 | # options on the menu or otherwise manipulate it. | |
| 23 | # | |
| 24 | # Arguments: | |
| 25 | # w - The name to use for the menubutton. | |
| 26 | # varName - Global variable to hold the currently selected value. | |
| 27 | # firstValue - First of legal values for option (must be >= 1). | |
| 28 | # args - Any number of additional values. | |
