Invoke sqlitecon::create with a window name, # a prompt string, a title to set a new top-level window, and the SQLite # database handle. For example: # # sqlitecon::create .sqlcon {sql:- } {SQL Console} db # # A toplevel window is created that allows you to type in SQL commands to # be processed on the spot. # # A limited set of dot-commands are supported: # # .table # .schema ?TABLE? # .mode list|column|multicolumn|line # .exit # # In addition, a new SQL function named "edit()" is created.

Whenever the # the function is called, it pops up a new toplevel window containing a # text editor screen initialized to the argument. When the "OK" button # is pressed, whatever revised text is in the text editor is returned as # the result of the edit() function.
