WindowsFrames

Hallo, ich suche eine Möglichkeit wie man folgendes Realisiert.
Ich möchte gerne ein Fenster mit mehreren Verschiebbaren Frames erstelen. Wie das bei HTML - Seiten z.B. funktioniert. Auch Visual .net ist ein Beispiel - Dort gibt es ein Fenster mit mehreren Teilframes die man gegenseitig verschieben kann. Und hier ist noch was schönes, was ich gerne wissen möchte. Wie kann man Fenster andocken und wieder Frei darstellen (Wie das z.B auch manchmal mit Symbolleister passiert- sind manchmal eigenes Fenster - aber auch andedockt am Fenster zu sehen).

Ich hoffe, ich habe nich verstänlich ausgedrückt-ist manchmal ganz schön schwierig in Worte zu fassen.

Danke!

Probier mal dieses Splitter Window Programm,
hab mal ich irgendwo gefunden, sollte das sein
was Du suchst:

#include <windows.h>
