The list of Tk widgets

Here is an attempt to write a script to display each widget available in Tk. It made the assumption that all widgets begin with a lowercase letter. But this assumption seems not valid as for instance ttk::deprecated is not a widget at all or clipboard is not listed.

 #
 # the dynamic list of Tk widgets
 # 

 puts " Tk version [package require Tk]"
 puts " ----"

 set tkCommands [lsort [info commands "::tk::\[a-z\]*"]] 

 foreach cmd $tkCommands { 
         puts [string range $cmd 6 end]
 }

 exit 

It gives :

 Tk version 8.5.7
 ----
 button
 canvas
 checkbutton
 entry
 frame
 label
 labelframe
 listbox
 mc
 mcmax
 mcmaxamp
 menubutton
 message
 panedwindow
 radiobutton
 scale
 scrollbar
 spinbox
 text
 toplevel

It works only with version 8.5 so far.

JH This completely misses the themed Tk widget set (::ttk::*).

LGT This script tries to correct this :

        #
        # the dynamic list of Tk widgets
        #

        puts " Tk version [package require Tk]"
        puts " ----"

        set tkCommands [lsort [info commands "::tk::\[a-z\]*"]]
        set ttkCommands [lsort [info commands "::ttk::\[a-z\]*"]]

        set allCommands [concat $tkCommands $ttkCommands]

        foreach cmd $allCommands {
                puts [string range $cmd 2 end]
        }

        exit 

It gives :

         Tk version 8.5.7
         ----
        tk::button
        tk::canvas
        tk::checkbutton
        tk::entry
        tk::frame
        tk::label
        tk::labelframe
        tk::listbox
        tk::mc
        tk::mcmax

        ttk::combobox
        ttk::copyBindings
        ttk::cursor
        ttk::deprecated
        ttk::deprecated'warning
        ttk::do'deprecate
        ttk::entry
        ttk::focusFirst
        ttk::frame
        ttk::globalGrab
        ttk::grabWindow
        ttk::label
        ttk::labelframe

        ttk::panedwindow
        ttk::progressbar
        ttk::radiobutton
        ttk::releaseGrab
        ttk::scale
        ttk::scrollbar
        ttk::separator
        ttk::setCursor
        ttk::setTheme
        ttk::sizegrip
        ttk::style
        ttk::takefocus
        ttk::takesFocus
        ttk::themes
        ttk::traverseTo
        ttk::treeview

Here is another attempt, which misses also ttk:: commmands, but not clipboard command and seems closer to documentation commands list :

        #
        # the dynamic list of Tk commands
        #
        set tclCommands [lsort [info commands]]
        puts "[llength $tclCommands] tcl commands."

        set tkVersion [package require Tk]

        set allCommands [lsort [info commands]]

        puts "[llength $allCommands] tcl and tk ($tkVersion) commands."
        set tkCommands {}

        foreach element $allCommands {
                if { [lsearch $tclCommands $element] < 0 } {
                        lappend tkCommands $element
                } 
        }

        foreach cmd $tkCommands {
                puts $cmd
        }

        exit 

It gives :

        92 tcl commands.
        152 tcl and tk (8.5.7) commands.

All the scripts above does NOT give The list of Tk widgets (regardless of Tk and/or ttk and/or BWidget)!
You have to check each returned command name afterwards by creating a (temporary) widget of that class in a catch.
Don't forget to destroy it at the end of the check! Be aware of toplevel and dialogs (e.g. on BWidget),
which may need an after to break a possibly set grab.
