- * - * First of all, we support 5 system properties that can be used to define - * the application to launch in any given case. These properties are:
- *
- * gnu.java.awt.peer.Desktop.html.command
- * gnu.java.awt.peer.Desktop.mail.command
- * gnu.java.awt.peer.Desktop.edit.command
- * gnu.java.awt.peer.Desktop.print.command
- * gnu.java.awt.peer.Desktop.open.command
- *
- *
- * These can be specified from the command line and have priority on every - * other setting.
- *
- * The second method supported is defining a Java preference.
- * The main preference node is a user node relative to the - * class gnu.java.awt.peer.ClasspathDesktopPeer. This node - * contains a child for each supported operation. The key for each type is - * always command: - *

- * gnu.java.awt.peer.Desktop.html.command

- * gnu.java.awt.peer.Desktop.edit.command
- * gnu.java.awt.peer.Desktop.print.command
- * gnu.java.awt.peer.Desktop.open.command
- *
- *
- * The access to these keys is done with the Preference API or, if outside - * of the java scope, is done in a backend dependent way. For example, - * with the GConf backend, you can access these properties - * with (may not be accurate on your system): - *

The manager handles - * the dispatch of all FocusEvents and - * KeyEvents, along with WindowEvents - * relating to the focused window. Users can use the manager - * to ascertain the current focus owner and fire events. - *
- *
- * The focus owner is the Component that receives - * key events. The focus owner is either the currently focused - * window or a component within this window. - *
- *
- * The underlying native windowing system may denote the active - * window or its children with special decorations (e.g. a highlighted - * title bar). The active window is always either a Frame - * or Dialog, and is either the currently focused - * window or its owner. - *
- *
- * Applets may be partitioned into different applet contexts, according - * to their code base. In this case, each context has its own - * KeyboardFocusManager, as opposed to the global - * manager maintained by applets which share the same context. - * Each context is insulated from the others, and they don't interact. - * The resulting behaviour, as with context division, depends on the browser - * supporting the applets. Regardless, there can only ever be - * one focused window, one active window and one focus owner - * per ClassLoader. - *
- *
- * To support this separation of focus managers, the manager instances - * and the internal state information is grouped by the - * ThreadGroup to which it pertains. With respect to - * applets, each code base has its own ThreadGroup, so the - * isolation of each context is enforced within the manager. - *
- *
- * By default, the manager defines TAB and Ctrl+TAB as the - * forward focus traversal keys and Shift+TAB and Ctrl+Shift+TAB - * as the backward focus traversal keys. No up or down cycle - * traversal keys are defined by default. Traversal takes effect - * on the firing of a relevant KEY_PRESSED event. - * However, all other key events related to the use of the - * defined focus traversal key sequence are consumed and not - * dispatched. - *
- *
- * These default traversal keys come into effect on all windows - * for which no alternative set of keys is defined.

There are two - * categories of key events: - * - *

"Key typed" events are higher-level, and have already - * compensated for modifiers and keyboard layout to generate a single Unicode - * character. It may take several key press events to generate one key typed. - * The getKeyCode method will return VK_UNDEFINED, - * and getKeyChar will return a valid Unicode character or - * CHAR_UNDEFINED. - * - *

"Key pressed" and "key released" events are lower-level, and - * are platform and keyboard dependent. They correspond to the actaul motion - * on a keyboard, and return a virtual key code which labels the key that was - * pressed. The getKeyCode method will return one of the - * VK_* constants (except VK_UNDEFINED), and the - * getKeyChar method is undefined. - * - *

Some keys do not generate key typed events, such as the F1 or HELP keys. - * Not all keyboards can generate all virtual keys, and no attempt is made to - * simulate the ones that can't be typed. Virtual keys correspond to the - * keyboard layout, so for example, VK_Q in English is VK_A in French. Also, - * there are some additional virtual keys to ease handling of actions, such - * as VK_ALL_CANDIDATES in place of ALT+VK_CONVERT. Do not rely on the value - * of the VK_* constants, except for VK_ENTER, VK_BACK_SPACE, and VK_TAB. - * - * @author Aaron M.

CAG manipulations - * work as an area-wise form of boolean logic, where the basic operations are: - *

  • Add (in boolean algebra: A or B)
    - *
  • Subtract (in boolean algebra: A and (not B) )
    - *
  • Intersect (in boolean algebra: A and B)
    - *
  • Exclusive Or
    - * Illustration of CAG operations
    - * Above is an illustration of the CAG operations on two ring shapes.

    - * - * Please note that constructing an Area can be slow - * (Self-intersection resolving is proportional to the square of - * the number of segments).

    • The flatness is a threshold value for deciding when - * a curved segment is consided flat enough for being approximated by - * a single straight line.

    The GNU Implementation of FlatteningPathIterator

    - -

    Sascha -Brawer, November 2003

    - -

    This document describes the GNU implementation of the class -java.awt.geom.FlatteningPathIterator. It does -not describe how a programmer should use this class; please -refer to the generated API documentation for this purpose. Instead, it -is intended for maintenance programmers who want to understand the -implementation, for example because they want to extend the class or -fix a bug.

    - - -

    Data Structures

    - -

    The algorithm uses a stack. Its allocation is delayed to the time -when the source path iterator actually returns the first curved -segment (either SEG_QUADTO or SEG_CUBICTO). -If the input path does not contain any curved segments, the value of -the stack variable stays null. In this quite -common case, the memory consumption is minimal.

    - -
    stack
    The variable stack is -a double array that holds the start, control and end -points of individual sub-segments.
    - -
    recLevel
    The variable recLevel -holds how many recursive sub-divisions were needed to calculate a -segment. The original curve has recursion level 0. For each -sub-division, the corresponding recursion level is increased by -one.
    - -
    stackSize
    Finally, the variable -stackSize indicates how many sub-segments are stored on -the stack.
    - -

    Algorithm

    - -

    The implementation separately processes each segment that the -base iterator returns.

    - -

    In the case of SEG_CLOSE, -SEG_MOVETO and SEG_LINETO segments, the -implementation simply hands the segment to the consumer, without actually -doing anything.

    - -

    Any SEG_QUADTO and SEG_CUBICTO segments -need to be flattened. Flattening is performed with a fixed-sized -stack, holding the coordinates of subdivided segments. When the base -iterator returns a SEG_QUADTO and -SEG_CUBICTO segments, it is recursively flattened as -follows:

    - -
    1. Intialization: Allocate memory for the stack (unless a -sufficiently large stack has been allocated previously). Push the -original quadratic or cubic curve onto the stack. Mark that segment as -having a recLevel of zero.
      2. - -
    2. If the stack is empty, flattening the segment is complete, -and the next segment is fetched from the base iterator.
      3. - -
    3. If the stack is not empty, pop a curve segment from the -stack. - -
      • If its recLevel exceeds the recursion limit, - hand the current segment to the consumer.
        • - -
      • Calculate the squared flatness of the segment. If it smaller - than flatnessSq, hand the current segment to the - consumer.
        • - -
      • Otherwise, split the segment in two halves. Push the right - half onto the stack. Then, push the left half onto the stack. - Continue with step two.
      4. -
    - -

    The implementation is slightly complicated by the fact that -consumers pull the flattened segments from the -FlatteningPathIterator. This means that we actually -cannot “hand the curent segment over to the consumer.” -But the algorithm is easier to understand if one assumes a -push paradigm.

    - - -

    Example

    - -

    The following example shows how a -FlatteningPathIterator processes a -SEG_QUADTO segment. It is (arbitrarily) assumed that the -recursion limit was set to 2.

    1. The data structures are initialized as follows. - -
      • The segment’s end point E, control point -C, and start point S are pushed onto the stack.
        • - -
      • Currently, the curve in the stack would be approximated by one - single straight line segment (S – E). - Therefore, stackSize is set to 1.
        • - -
      • This single straight line segment is approximating the original - curve, which can be seen as the result of zero recursive - splits. Therefore, recLevel[0] is set to - zero.
      - -Column A shows the state after the initialization step.
      2. - -
    2. The algorithm proceeds by taking the topmost curve segment -(S – C – E) from the stack. - -
      • The recursion level of this segment (stored in - recLevel[0]) is zero, which is smaller than - the limit 2.
        • - -
      • The method java.awt.geom.QuadCurve2D.getFlatnessSq - is called to calculate the squared flatness.
        • - -
      • For the sake of argument, we assume that the squared flatness is - exceeding the threshold stored in flatnessSq. Thus, the - curve segment S – C – E gets - subdivided into a left and a right half, namely - Sl – Cl – - El and Sr – - Cr – Er. Both halves are - pushed onto the stack, so the left half is now on top. - -
         
        The left half starts at the same point - as the original curve, so Sl has the same - coordinates as S. Similarly, the end point of the right - half and of the original curve are identical - (Er = E). More interestingly, the left - half ends where the right half starts. Because - El = Sr, their coordinates need - to be stored only once, which amounts to saving 16 bytes (two - double values) for each iteration.
      - -Column B shows the state after the first iteration.
      3. - -
    3. Again, the topmost curve segment (Sl -– Cl – El) is -taken from the stack. - -
      • The recursion level of this segment (stored in - recLevel[1]) is 1, which is smaller than - the limit 2.
        • - -
      • The method java.awt.geom.QuadCurve2D.getFlatnessSq - is called to calculate the squared flatness.
        • - -
      • Assuming that the segment is still not considered - flat enough, it gets subdivided into a left - (Sll – Cll – - Ell) and a right (Slr - – Clr – Elr) - half.
      - -Column C shows the state after the second iteration.
      4. - -
    4. The topmost curve segment (Sll – -Cll – Ell) is popped from -the stack. - -
      • The recursion level of this segment (stored in - recLevel[2]) is 2, which is not smaller than - the limit 2. Therefore, a SEG_LINETO (from - Sll to Ell) is passed to the - consumer.
      - - The new state is shown in column D.
      5. - - -
    5. The topmost curve segment (Slr – -Clr – Elr) is popped from -the stack. - -
      • The recursion level of this segment (stored in - recLevel[1]) is 2, which is not smaller than - the limit 2. Therefore, a SEG_LINETO (from - Slr to Elr) is passed to the - consumer.
      - - The new state is shown in column E.
      6. - -
    6. The algorithm proceeds by taking the topmost curve segment -(Sr – Cr – -Er) from the stack. - -
      • The recursion level of this segment (stored in - recLevel[0]) is 1, which is smaller than - the limit 2.
        • - -
      • The method java.awt.geom.QuadCurve2D.getFlatnessSq - is called to calculate the squared flatness.
        • - -
      • For the sake of argument, we again assume that the squared - flatness is exceeding the threshold stored in - flatnessSq. Thus, the curve segment - (Sr – Cr – - Er) is subdivided into a left and a right half, - namely - Srl – Crl – - Erl and Srr – - Crr – Err. Both halves - are pushed onto the stack.
      - - The new state is shown in column F.
      7. - -
    7. The topmost curve segment (Srl – -Crl – Erl) is popped from -the stack. - -
      • The recursion level of this segment (stored in - recLevel[2]) is 2, which is not smaller than - the limit 2. Therefore, a SEG_LINETO (from - Srl to Erl) is passed to the - consumer.
      - - The new state is shown in column G.
      8. - -
    8. The topmost curve segment (Srr – -Crr – Err) is popped from -the stack. - -
      • The recursion level of this segment (stored in - recLevel[2]) is 2, which is not smaller than - the limit 2. Therefore, a SEG_LINETO (from - Srr to Err) is passed to the - consumer.
      - - The new state is shown in column H.
      9. - -
    9. The stack is now empty. The FlatteningPathIterator will fetch the -next segment from the base iterator, and process it.
      10. - -
