block_matched
Description:
public uint block_matched (void* instance, SignalMatchType mask, uint signal_id, Quark detail, Closure? closure, void* func, void* data)
Blocks all handlers on an instance that match a certain selection criteria.
The criteria mask is passed as a combination of SignalMatchType flags, and
the criteria values are passed as arguments. A handler must match on all flags set in mask to be blocked (i.e. the match is
conjunctive).
Passing at least one of the g_signal_match_id, g_signal_match_closure, g_signal_match_func or g_signal_match_data match flags is required for successful matches. If no handlers were found, 0 is returned, the number of blocked handlers otherwise.
Support for g_signal_match_id was added in GLib 2.78.
Parameters:
| instance |
The instance to block handlers from. |
| mask |
Mask indicating which of |
| signal_id |
Signal the handlers have to be connected to. |
| detail |
Signal detail the handlers have to be connected to. |
| closure |
The closure the handlers will invoke. |
| func |
The C closure callback of the handlers (useless for non-C closures). |
| data |
The closure data of the handlers' closures. |
Returns:
|
The number of handlers that matched. |
