Detailed Description

Internal class.

The main frame widget KMdiMainFrm consists of 2 child widgets. One is this class. It's the widget where the child frames (emulated toplevel MDI views) live in. This class is the manager for the child frame widgets because it controls the Z-order widget stack of KMdiChildFrm's. It provides all placing and positioning algorithms for docked (attached) MDI views.

KMdiChildArea doesn't know anything about the actual MDI views. It only knows and manages the frame widgets of attached MDI views. All actions and stuff concerning only to childframes are handled here.

static

Gets all caption colors, consistent with current WM settings (or other Desktop settings e.g.

system settings for win32) This method is useful not only for KMDI child windows. Colors are returned via activeBG, activeFG, inactiveBG, inactiveFG references.

Deprecated:
