        o -wrapLicence default set to 1
        o new options: -child, and -information.
          Where: -child enables a custome widget to be embedded in the
          dialog area, and -informations adds a further control button
          and the creation of an information popup.  
 

    gnocl::infoBar
        o new option -text
 

    gnocl::comboBox
        o new options -onActivate, -onButtonPress, -onButtonRelease, -onKeyPress
        o new commands getSelection, grabFocus, activate
        o entry strings will be automatcially prepended to pulldown menu and duplicates removed
        o combobox entry widget automatically registered during creation.

    gnocl::scrolledWindow

May Update

Only a few enhancements to report for April.  At the moment using the gnocl::text  -swap and -balanceQuotes options needs some care when implemented. As both of these options work in response to a Gtk key-release signal, using these in conjunction with -onKeyPress may produce some unexpected results. For reason for this is that the Gtk internals allow for multiple bindings to various events which these are prioritized based upon their position within a processing stack. To ensure complete control over the ordering, it is advised to set these options using the widget configure subcommand.

2018-04:
    gnocl::text
        o cget -swap, -balanceQuotes and -margins now work correctly
    gnocl::winfo
        o new subcommand "children".
    gnocl::application
        o option -version default set to 0.1
