Yep.
But now it would be a good idea to overcome this situation - that obviously
is introduced by two different teams doing the LCL and the RTL and designs -
by a unified solution, that handles the thread-to-mainthread signaling in a
single WidgetType-independent (set of) unit(s) (supposedly residing in the
RTL), that provides an interface that can used by any WidgetType in the LCL
and is versatile enough to allow for WidgetTypes that need to adhere to an
external GUI-provided event Queue (such as Windows) and a parallel internal
non-GUI-EventQueue (such as KDE).
Based on this the "CustomDrawn" and "fpGUI" WidgetTypes can easily provide
this full functionality, and a non-horrible "active NoGUI" WidgetType can be
done.
What are you waiting for ?
All you need to do is implement an event loop. All the rest is there.
Michael.
