* generator/CallbackGen.cs: Generate wrappers to map from managed delegates to native ones. * generator/Ctor.cs: Call parms.Initialize for the static case. * generator/Parameters.cs: Add "CType" property. Append [] to CSType if necessary. Add "HideData" property if a container wishes to hide the user_data (used in callbacks). (Initialize): Add case for callback. * generator/SymbolTable.cs: Add size_t. * glue/program.c: string[] marshalling is no longer broken, remove hack. * sources/Gtk.metadata: Disable GtkColorSelection.SetChangePaletteHook and GtkTreeView.GetSearchEqualFunc for now, they return delegates and we don't support native->managed delegate mapping yet. svn path=/trunk/gtk-sharp/; revision=7133

* generator/CallbackGen.cs: Generate wrappers to map
|
||||
from managed delegates to native ones.
|
||||
* generator/Ctor.cs: Call parms.Initialize for the static case.
|
||||
* generator/Parameters.cs: Add "CType" property. Append []
|
||||
to CSType if necessary. Add "HideData" property if a container
|
||||
wishes to hide the user_data (used in callbacks).
|
||||
(Initialize): Add case for callback.
|
||||
* generator/SymbolTable.cs: Add size_t.
|
||||
|
||||
* glue/program.c: string[] marshalling is no longer broken,
|
||||
remove hack.
|
||||
|
||||
* sources/Gtk.metadata: Disable
|
||||
GtkColorSelection.SetChangePaletteHook and
|
||||
GtkTreeView.GetSearchEqualFunc for now, they return delegates and
|
||||
we don't support native->managed delegate mapping yet.
