| 17:46 | * mainframe.tcl: Modified menu creation/setmenustate functions to support a new model of menustate. Instead of enabling/disabling a menu item whenever any one of its tags changes state, now it only enables menu items if all of its tags are set. This makes it really easy to, say, only enable the "New Action" entry if both a project is open and an element is selected. check-in: 0406abeac2 user: ericm tags: trunk | |
