Method Details

onBindingTransformFunc

boolean onBindingTransformFunc(CallbackHandler __self,
 @Nonnull
 Binding binding,
 @Nonnull
 Value from_value,
 @Nonnull
 Value to_value,
 @Nullable
 Pointer user_data)

A function to be called to transform @from_value to @to_value.

If this is the @transform_to function of a binding, then @from_value
is the @source_property on the @source object, and @to_value is the
@target_property on the @target object. If this is the
@transform_from function of a %G_BINDING_BIDIRECTIONAL binding,
then those roles are reversed.

Parameters:

binding - a #GBinding

from_value - the #GValue containing the value to transform

to_value - the #GValue in which to store the transformed value

user_data - data passed to the transform function

Returns:

%TRUE if the transformation was successful, and %FALSE otherwise
