The ::activate signal is emitted when the user activates
a child widget in a
GtkFlowBox, either by clicking or
double-clicking, or by using the Space or Enter key.
While this signal is used as a [keybinding signal][GtkBindingSignal], it can be used by applications for their own purposes.
|Default handler: |
The default handler is called before the handlers added via
|Signal can be directly emitted on objects from user code|
|Available since: 3.0|
