Subject: [PATCH 2/5] connectableobject: introduce
|
|
FCITX_DECLARE_SIGNAL_WITH_COMBINER
|
|
|
|
In order to correctly downcast SignalBase, in the next step,
|
|
we will switch all initialisation of SignalAdaptor to use
|
|
SignalType::combinerType.
|
|
|
|
Let's introduce a new macro to ease to initialisation of those
|
|
signals which employs custom combiner.
|
|
|
|
Arguably, the custom combiner is an implementation detail,
|
|
thus it'll be put in source files. Hence, the macro is intended
|
|
to be used outside of class declaration.
