-# uiArea
-
-uiArea is a uiControl that provides a canvas you can draw on. It receives keyboard and mouse events, supports scrolling, is DPI aware, and has several other useful features. A uiArea consists of the drawing area itself and horizontal and vertical scrollbars.
-
-## The Area Handler
-
-A uiArea is driven by an *area handler*. An area handler is an object with several methods that uiArea calls to do certain tasks. To create an area handler, simply have a structure whose first member is of type `uiAreaHandler`:
-
-```c
-struct uiAreaHandler {
-	void (*Draw)(uiAreaHandler *h, uiArea *a, uiAreaDrawParams *p);
-	void (*HScrollConfig)(uiAreaHandler *h, uiArea *a, uiAreaScrollConfig *c);
-	void (*VScrollConfig)(uiAreaHandler *h, uiArea *a, uiAreaScrollConfig *c);
-}
-```
-
-## Drawing
-
-Unlike drawing canvas controls in other toolkits, uiArea does **not** have a fixed size. The coordinate (0, 0) is always the top-left corner of the drawing area, regardless of how big the uiArea is in the current window or where the scrollbars presently are. Instead, you simulate a size by setting the scrollbar bounds, and you are given the current scrolling positions to base your drawing with.
-
-The visible drawing area is called the *content area* by the drawing machinery.
-
-TODO have a diagram.
-
-When a part of the uiArea needs to be redrawn, the area handler's `Draw()` method is called. It receives the area handler, the uiArea, and a structure of parameters necessary for drawing.
-
-```c
-struct uiAreaDrawParams {
-	uiDrawContext *context;
-
-	intmax_t contentWidth;
-	intmax_t contentHeight;
-
-	intmax_t hscrollpos;
-	intmax_t vscrollpos;
-
-	intmax_t clipX;
-	intmax_t cilpY;
-	intmax_t clipWidth;
-	intmax_t clipHeight;
-
-	TODO dpiX;
-	TODO dpiY;
-};
-```
-
-`context` is the drawing context; see drawing.md for details.
-
-`contentWidth` and `contentHeight` is the current width and height of the content area. `hscrollpos` and `vscrollpos` are the current horizontal and vertical positions of the scrollbars, in units defined by the scrollbar configurations; see below.
-
-`clipX`, `clipY`, `clipWidth`, and `clipHeight` define a rectangle, in content area coordinates, that the OS has requested to be redrawn. You can use this to optimize your drawing by only drawing where drawing is needed; the OS may choose to drop any drawing done outside the clip rectangle.
-
-`dpiX` and `dpiY` are the uiArea's current DPI in the X and Y directions, respectively. Do not save these values; they are not guaranteed to stay the same once `Draw()` returns.
