TkLua_01a - Display of predefined Tk Colors

Similar to "TkLua_01", the program "TkLua_01a" also produces a color table - but now the table contains all predefined Tk colors. Again, it is possible to click on every color to see the corresponding RGB definition.

Because of the large number of colors it was necessary to place the table within a separate frame object and to associate two scrollbar objects in order to position the (visible area of the) table within that frame. Apart from these changes, the program is structured like its predecessor "TkLua_01".

"TkLua_01a" should be invoked without any command line arguments 

  lua TkLua_01a.lua

and presents itself as shown below (be patient, please, it takes a while for the window to come up)
