|
|
.h1 System Overview
|
|
|
|
DVX is built as a five-layer architecture, with each layer
|
|
providing services to the layer above it.
|
|
|
|
.h2 Video Layer
|
|
|
|
The video layer (dvxVideo) handles VESA VBE initialization,
|
|
linear framebuffer mapping, backbuffer allocation, and pixel
|
|
format detection. It supports 8-bit, 16-bit, and 32-bit color
|
|
depths.
|
|
|
|
.h2 Drawing Layer
|
|
|
|
The drawing layer (dvxDraw) provides primitive rendering
|
|
operations: filled rectangles, beveled borders, text rendering,
|
|
bitmap blitting, and clipped drawing.
|
|
|
|
.h2 Compositor
|
|
|
|
The compositor (dvxComp) manages a dirty rectangle list. Only
|
|
regions that have changed since the last frame are flushed from
|
|
the system RAM backbuffer to the video card's linear framebuffer.
|
|
|
|
.h2 Window Manager
|
|
|
|
The window manager (dvxWm) handles the window stack, chrome
|
|
rendering (title bars, borders, close buttons), drag and resize
|
|
interaction, focus management, and menu bars.
|
|
|
|
.h2 Application Layer
|
|
|
|
The application layer (dvxApp) ties everything together with
|
|
the event loop, mouse and keyboard input, accelerator tables,
|
|
and the public API used by applications.
