Methods

evaluate
expressionWatchEvaluate Source #
Arguments
| :: (HasCallStack, MonadIO m) | |
| => ExpressionWatch |
|
| -> GValue |
|
| -> m Bool | Returns: |
Evaluates the watched expression and on success stores the result
in value.
This is equivalent to calling expressionEvaluate with the
expression and this pointer originally used to create watch.
ref
Arguments
| :: (HasCallStack, MonadIO m) | |
| => ExpressionWatch |
|
| -> m ExpressionWatch | Returns: the |
Acquires a reference on the given ExpressionWatch.
unref
Arguments
| :: (HasCallStack, MonadIO m) | |
| => ExpressionWatch |
|
| -> m () |
Releases a reference on the given ExpressionWatch.
If the reference was the last, the resources associated to self are
freed.
unwatch
expressionWatchUnwatch Source #
Arguments
| :: (HasCallStack, MonadIO m) | |
| => ExpressionWatch |
|
| -> m () |
Stops watching an expression that was established via expressionWatch.
