fn.call(...), another generated wrapper exposinghandle(), or null. Returns null when the argument carries no pointer.
Source is the raw handle, raw buffer, wrapper, or null.A raw pointer carrier or null when no pointer is present.getLib ()
Returns the opened native library for this generated wrapper.
The opened native library.handle ()
Returns the wrapped NativeHandle.
The wrapped NativeHandle.isNull ()
Returns true when the wrapped handle is null.
A bool.describe ()
Returns a small string for debugging generated wrappers.
A string.asWidget ()

Name is the signal name.CallbackObj is the generated callback wrapper to connect.The connected handler id.disconnectSignalHandler (int HandlerId)
Disconnects one retained signal handler id.
HandlerId is the signal handler id to disconnect.None.setOnActivate (callback Fn, UserData = null)
Emitted when the font dialog button is activated. The
::activatesignal onGtkFontDialogButtonis an action signal and emitting it causes the button to pop up its dialog.
