Gnocl -the Tcl/Gtk Bindings

The gtk api provides it own status bar widget which could be used for embedded widget feedback but this it aimed at being used as part of a application's toplevel window. A complex UI may have several component zone each of which giving its own feedback. This simpler messaging areas provided this capability by making feedback available by directly displaying the contents of global variables rather than pushing items onto a status message stack. if 0 { +-------------------------------------------------------------------------+ | msg0                                      |  msg1   |  msg2   |  msg3   |    +-------------------------------------------------------------------------+ } ## # Simple Tcl/Gnocl based message bar # ref = unique ref  (could be uapp or parent widget-id} # itesm = list of extra field to be displayed in var val tooltip # args = options to be passed to container proc gnocl::messageBar { {ref myapp} {values { {A a Z} {B b Y} {C c X} }} args} {     set bar [gnocl::

What to do... Make changes to the widgetFunc function to enable the GnoclOption function for that option to return a value by setting the ret to point ot a TclObj. /* this is a gnocl option handler ?? */ case GNOCL_CGET_NOTHANDLED: { /* cget for gnocl options handled in option function * the caveat here is that different widgets with the same option name may act differently, * if this is the case, then would it be more practical to create specific option functions? * (08/09/25) */ Tcl_Obj *ret = NULL; options[idx2].func ( interp, &options[idx2], G_OBJECT ( area ), &ret ); Tcl_SetObjResult (interp, ret); }
