[Question] Do GObject::Bindings need to be unbound manually to free memory?

[BigBoyBarney]

Hi!

This isn't technically an issue, I was just wondering whether GObject::Bindings worked the same way as GObject::SignalConnections, where we have to explicitly call #disconnect to make sure the memory is freed.

Example:

label1 = Gtk::Label.new
label2 = Gtk::Label.new

label_binding = GObject::Binding.new(source: label1, source_property: "label", target: label2, target_property: "label", flags: :bidirectional)

label1.label = "Hello!"
# label2.label is now "Hello!" as well

Will the memory be freed automatically, or would I need to call label_binding.unbind first?

Thanks in advance! <3

Hi,

Yes, you need to disconnect it manually or memory will leak, this is because we need to store a reference to the proc we use internally, otherwise it will be garbage collected and GObject will access invalid memory and crash.

However... I dislike this pattern and want to change this so I was working on a way to connect objects without the need to manually disconnect to avoid memory leaks, basic tests worked but need more tests to be ready.

That makes sense, thank you!
