gtk:expression-watch-evaluate-value (watch)

watch -- a gtk:expression-watch instance

The value with the result.

Evaluates the watched expression and on success returns the result. This is equivalent to calling the gtk:expression-evaluate function with the expression and the object originally used to create watch.

This function is a variant of the gtk:expression-watch-evaluate function that avoids the usage of a g:value instance to get the value of the expression.
