+ * Encapsulates the data for a single Ibex box as well as all layout + * rendering logic. + *

+ * + *

The rendering process consists of four phases; each requires + * one DFS pass over the tree

+ *
  1. repacking: children of a box are packed into columns + * and rows according to their colspan/rowspan attributes and + * ordering. + *
    1. reconstraining: Minimum and maximum sizes of columns are computed. + *
    2. resizing: width/height and x/y positions of children + * are assigned, and PosChange/SizeChanges are triggered. + *
    3. repainting: children draw their content onto the PixelBuffer. + *
    + * + * The first three passes together are called the reflow phase. + * Reflowing is done in a seperate pass since PosChanges and + * SizeChanges trigger an Surface.abort; if rendering were done in the same + * pass, rendering work done prior to the Surface.abort would be wasted. + */ +public final class Box extends JSScope implements Scheduler.Task { + + // Macros ////////////////////////////////////////////////////////////////////// + + //#define LENGTH int + //#define MARK_REPACK for(Box b2 = this; b2 != null && !b2.test(REPACK); b2 = b2.parent) b2.set(REPACK); + //#define MARK_REPACK_b for(Box b2 = b; b2 != null && !b2.test(REPACK); b2 = b2.parent) b2.set(REPACK); + //#define MARK_REPACK_parent for(Box b2 = parent; b2 != null && !b2.test(REPACK); b2 = b2.parent) b2.set(REPACK); + //#define MARK_REFLOW for(Box b2 = this; b2 != null && !b2.test(REFLOW); b2 = b2.parent) b2.set(REFLOW); + //#define MARK_REFLOW_b for(Box b2 = b; b2 != null && !b2.test(REFLOW); b2 = b2.parent) b2.set(REFLOW); + //#define MARK_RESIZE for(Box b2 = this; b2 != null && !b2.test(RESIZE); b2 = b2.parent) b2.set(RESIZE); + //#define MARK_RESIZE_b for(Box b2 = b; b2 != null && !b2.test(RESIZE); b2 = b2.parent) b2.set(RESIZE); + //#define CHECKSET_SHORT(prop) short nu = (short)toInt(value); if (nu == prop) break; prop = nu; + //#define CHECKSET_INT(prop) int nu = toInt(value); if (nu == prop) break; prop = nu; + //#define CHECKSET_FLAG(flag) boolean nu = toBoolean(value); if (nu == test(flag)) break; if (nu) set(flag); else clear(flag); + //#define CHECKSET_BOOLEAN(prop) boolean nu = toBoolean(value); if (nu == prop) break; prop = nu; + //#define CHECKSET_STRING(prop) if ((value==null&&prop==null)||(value!=null&&JS.toString(value).equals(prop))) break; prop=JS.toString(value); + + protected Box() { super(null); } + + static Hash boxToCursor = new Hash(500, 3); // FIXME memory leak + public static final int MAX_LENGTH = Integer.MAX_VALUE; + static final Font DEFAULT_FONT; + + static { + Font f = null; + try { f = Font.getFont((Stream)Main.builtin.get("fonts/vera/Vera.ttf"), 10); } + catch(JSExn e) { Log.info(Box.class, "should never happen: "+e); } + DEFAULT_FONT = f; + } + + // FIXME update these + // box properties can not be trapped + static final String[] props = new String[] { + "shrink", "hshrink", "vshrink", "x", "y", "width", "height", "cols", "rows", + "colspan", "rowspan", "align", "visible", "packed", "globalx", "globaly", + "minwidth", "maxwidth", "minheight", "maxheight", "indexof", "thisbox", "clip", + "numchildren", "redirect", "cursor", "mouse" + }; + + // FIXME update these + // events can have write traps, but not read traps + static final String[] events = new String[] { + "Press1", "Press2", "Press3", + "Release1", "Release2", "Release3", + "Click1", "Click2", "Click3", + "DoubleClick1", "DoubleClick2", "DoubleClick3", + "Enter", "Leave", "Move", "ChildChange", + "KeyPressed", "KeyReleased", "SizeChange", + "Focused", "Maximized", "Minimized", "Close" + }; + + // Flags ////////////////////////////////////////////////////////////////////// + + static final int MOUSEINSIDE = 0x00000001; + static final int VISIBLE = 0x00000002; + static final int PACKED = 0x00000004; + static final int HSHRINK = 0x00000008; + static final int VSHRINK = 0x00000010; + static final int BLACK = 0x00000020; // for red-black code + + static final int FIXED = 0x00000040; + static final boolean ROWS = true; + static final boolean COLS = false; + + static final int ISROOT = 0x00000080; + static final int REPACK = 0x00000100; + static final int REFLOW = 0x00000200; + static final int RESIZE = 0x00000400; + static final int RECONSTRAIN = 0x00000800; + static final int ALIGN_TOP = 0x00001000; + static final int ALIGN_BOTTOM = 0x00002000; + static final int ALIGN_LEFT = 0x00004000; + static final int ALIGN_RIGHT = 0x00008000; + static final int ALIGNS = 0x0000f000; + static final int CURSOR = 0x00010000; // if true, this box has a cursor in the cursor hash; FEATURE: GC issues?
