A GtkBuilderScope
implementation for the C language.
GtkBuilderCScope
instances use symbols explicitly added to builder
with prior calls to builderCScopeAddCallbackSymbol
.
If developers want to do that, they are encouraged to create their
own scopes for that purpose.
In the case that symbols are not explicitly added; GTK will uses
GModule
’s introspective features (by opening the module Nothing
) to
look at the application’s symbol table. From here it tries to match
the signal function names given in the interface description with
symbols in the application.
Note that unless builderCScopeAddCallbackSymbol
is
called for all signal callbacks which are referenced by the loaded XML,
this functionality will require that GModule
be supported on the platform.

addCallbackSymbol
builderCScopeAddCallbackSymbol Source #
:: (HasCallStack, MonadIO m, IsBuilderCScope a) | |
=> a |
|
-> Text |
|
-> Callback |
|
-> m () |
Adds the callbackSymbol
to the scope of builder
under the
given callbackName
.
Using this function overrides the behavior of
builderCreateClosure
for any callback symbols that
are added. Using this method allows for better encapsulation as it
does not require that callback symbols be declared in the global
namespace.
new
:: (HasCallStack, MonadIO m) | |
=> m BuilderCScope | Returns: a new |
Creates a new GtkBuilderCScope
object to use with future
GtkBuilder
instances.
Calling this function is only necessary if you want to add
custom callbacks via builderCScopeAddCallbackSymbol
.
