Hi, I couldn’t find correct documentation, but as I remember from other GNOME applications, we don’t need to add an action to show help-overlay.
Actually changing app.show-help-overlay to win.show-help-overlay works the same with less code.
app.show-help-overlay
win.show-help-overlay
Do we have special case to use this action? Can we remove this action? I tested and seemed the same to me.
That is correct: GtkApplication will create a win.show-help-overlay action automatically if it can find a GResource at ui/help-overlay.ui which defines a GtkShortcutWindow. See the GtkApplication API reference.
GtkApplication
ui/help-overlay.ui
GtkShortcutWindow
