* arguments
|
|
|
|
- how to add arguments
|
|
- create an identifier in the enum, starting with ARG_
|
|
example: ARG_RATE
|
|
- add the property by adding a
|
|
g_object_class_install_property line
|
|
FIXME: what is name/nick/blurb in the paramspec ?
|
|
- if the argument is readable, a block of code for it needs to be added
|
|
to the _get_property function.
|
|
|
|
- default value
|
|
- default value should be set in _init function
|
|
- default value can be specified in paramspec (but I don't think this
|
|
is used anywhere)
|
|
|
|
|
|
- things to check/possible problems
|
|
- do you have a _get_property function ?
|
|
- do you have a _set_property function ?
|
|
- do both have a default handler that handles invalid property ID's ?
|
|
- are the _get/_set_property handlers assigned to the class's struct ?
|
|
- do you have a g_object_class_install_property line for the argument ?
|
|
- are there restrictions on when your parameters can change ?
|
|
e.g. sample rate is not something that should be changed while PLAYING,
|
|
so it can only be changed in the NULL state
|
|
- did you use ARG_ ... consistently everywhere ?
|
|
|
|
|
|
- my own problems:
|
|
- how to set defaults and make the paramspec be right for them ?
|
|

* audio

- explanation of difference of width and depth
|
|
- guidelines on how to implement this properly
