GObject subclass will create a Python property accessor for the
GObject ParamSpec.
:param callable getter:
getter to get the value of the property
:param callable setter:
setter to set the value of the property
:param type type:
type of property
:param default:
default value, must match the property type.
:param str nick:
short description
:param str blurb:
long description
:param GObject.ParamFlags flags:
parameter flags
:keyword minimum:
minimum allowed value (int, float, long only)
:keyword maximum:
maximum allowed value (int, float, long only)
.. code-block:: python
class MyObject(GObject.Object):
prop = GObject.Property(type=str)
obj = MyObject()
obj.prop = 'value'
obj.prop # now is 'value'
The API is similar to the builtin :py:func:`property`:
.. code-block:: python
class AnotherObject(GObject.Object):
value = 0
@GObject.Property
def prop(self):
'Read only property.'
return 1
@GObject.Property(type=int)
def propInt(self):
'Read-write integer property.'
return self.value
@propInt.setter
def propInt(self, value):
self.value = value
