June Update

2018-05:
    gnocl::scrolledWindow
        o when adding non-scrollable child widgets, created viewport has no shadow by default.
    gnocl::comboEntry
        o new options -primaryIcon and -secondaryIcon

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

April Update

Some minor enhancements to the core modules. The most significant is a fix the gnocl::list row checking. Previously, if a row was creates with columns less than the total for the list model, then individual cell renderers would not have been created. The fix will check the proposed row length matches that which is expected.


2018-03:
    gnocl::tree, gnocl::list
        o new option -sensitive
    gnocl::list
        o enhanced error checking of item list lengths when adding

          of entries.   
    gnocl::dialog
        o fixed problem with -data option.
    gnocl::text
        o search command no longer requires -tags option to be set,

          positions of search string
