WJG (03/03/18) At home my family prefer Word to LibreOffice, never mind. The main reason they prefer it is nothing at all to with functionality. They don't remember where embedded menu options are so prefer the switchable toolbars that Word has. So, I thought that I'd put something together like this as a simple text editor in [Gnocl]. At first I wasn't convinced of the speed benefits but now I am. Less clutter on screen, more space for the edit widget and no waiting for menus to build themselves. Added to this, the programming was so much less complicated. I saw this mixture of tabbed menus and pull-down menus first in the Maya CGI animation system back in the 1990s, an application with a lot of widgets. So, perhaps this UI paradigm is worth a second glance. The application uses [Gnocl] rather than Tk to create the UI. The script takes advantage of the widget -name option to specify objects rather than using their widget-ids. Makes life a lot easier! Bye-bye global declarations and namespaces. Finally, no need to create custom tags; the [Gnocl] text widget does it for you with the -useMarkup option to create a key set of Pango/HTML markup tags. ====== ## test-menu-tabs.tcl #!/bin/sh # the next line restarts using tclsh \ exec tclsh "$0" "$@" if { [catch { package present Gnocl } ] } { package require Gnocl } #--------------- #
