ScreenPainter

The 2D drawing proxy. You acquire one of these with SimpleWindow.draw rather than constructing it directly. Then, it is reference counted so you can pass it at around and when the last ref goes out of scope, the buffered drawing activities are all carried out.

Functions

clear void clear(Color color)
drawArc void drawArc(Point upperLeft, int width, int height, int start, int length): Draws an arc inside the bounding box given by upperLeft, width, and height, from the angle (start / 64) degrees for (length / 64) degrees of rotation.
drawCircle void drawCircle(Point upperLeft, int diameter): this function draws a circle with the drawEllipse() function above, it requires the upper left point and the radius
drawEllipse void drawEllipse(Point upperLeft, Point lowerRight): Arguments are the points of the bounding rectangle
drawImage void drawImage(Point upperLeft, Image i, Point upperLeftOfImage, int w, int h)
drawLine void drawLine(Point starting, Point ending): Draws a pen using the current pen / outlineColor
drawPixel void drawPixel(Point where): Drawing an individual pixel is slow. Avoid it if possible.
drawPixmap void drawPixmap(Sprite s, Point upperLeft, Point imageUpperLeft, Size sliceSize): Draws a pixmap (represented by the Sprite class) on the drawable.
drawPolygon void drawPolygon(Point[] vertexes): .
drawPolygon void drawPolygon(Point[] vertexes): .
drawRectangle void drawRectangle(Point upperLeft, int width, int height)
void drawRectangle(Point upperLeft, Size size)
void drawRectangle(Point upperLeft, Point lowerRightInclusive)
void drawRectangle(Rectangle rect): Draws a rectangle using the current pen/outline color for the border and brush/fill color for the insides The outer lines, inclusive of x = 0, y = 0, x = width - 1, and y = height - 1 are drawn with the outlineColor The rest of the pixels are drawn with the fillColor. If fillColor is transparent, those pixels are not drawn.
drawRectangleRounded void drawRectangleRounded(Rectangle rect, int borderRadius)
void drawRectangleRounded(Point upperLeft, Size size, int borderRadius)
void drawRectangleRounded(Point upperLeft, Point lowerRight, int borderRadius): Draws a rectangle with rounded corners. It is outlined with the current foreground pen and filled with the current background brush.
drawText void drawText(Point upperLeft, char[] text, Point lowerRight, uint alignment): Draws a string in the window with the set font (see setFont to change it).
drawText void drawText(DrawableFont font, Point upperLeft, char[] text): Draws text using a custom font.
fontHeight int fontHeight()
invalidateRect void invalidateRect(Rectangle rect): If you are using manual invalidations, this informs the window system that a section needs to be redrawn.
notifyCursorPosition void notifyCursorPosition(int x, int y, int width, int height): EXPERIMENTAL. subject to change.
scrollArea void scrollArea(Point upperLeft, int width, int height, int dx, int dy): Scrolls the contents in the bounding rectangle by dx, dy. Positive dx means scroll left (make space available at the right), positive dy means scroll up (make space available at the bottom)
setClipRectangle arsd.color.Rectangle setClipRectangle(Point pt, int width, int height)
arsd.color.Rectangle setClipRectangle(arsd.color.Rectangle rect): Sets the clipping region for drawing. If width == 0 && height == 0, disabled clipping.
setFont void setFont(OperatingSystemFont font)
textSize Size textSize(char[] text)

Detailed Description

Most functions use the outlineColor instead of taking a color themselves. ScreenPainter is reference counted and draws its buffer to the screen when its final reference goes out of scope.
