Field Detail

REL

public final static int REL

If this bit is cleared,then coordinates are used directly from x,y coordinates of view location

public final static int X_CC

Arrange mode, view is arranged by center along X axis to the center along X axis of previous rectangle

public final static int X_LC

Arrange mode, view is arranged by center along X axis to the left of previous rectangle

public final static int X_LL

Arrange mode, view is arranged by left side to the left side of previous rectangle

public final static int X_LR

Arrange mode, view is arranged by right side to the left side of previous rectangle

public final static int X_RC

Arrange mode, view is arranged by center along X axis to the right of previous rectangle

public final static int X_RL

Arrange mode, view is arranged by left side to the right of previous rectangle

public final static int X_RR

Arrange mode, view is arranged by right side to the right side of previous rectangle

public final static int X_UN

Arrange mode, X coordinate is get from x coordinate of view location

public final static int Y_BB

Arrange mode, view is arranged by bottom side to the bottom of previous rectangle

public final static int Y_BC

Arrange mode, view is arranged by center along Y axis to the bottom of previous rectangle

public final static int Y_BT

Arrange mode, view is arranged by top side to the bottom of previous rectangle

public final static int Y_CC

public CompositeView()

Constructs composite view

public void add(View v, int mode)

Adds element with insets coordinates ( 0,0 )

Parameters:

v

mode

See Also:

add(ru.biosoft.graphics.View,int,java.awt.Point)

public void add(View v, int mode, Point insets)

Adds new elements and arrange them relative the previous objects.

Parameters:

v - specified View

mode - mode to arrange new element relative previous: Abrevations:

X_RL
| ||
| |--- boundary of new element
| ---- boundary of minimal rectangle, described all
|      previous elements
------ x or y coordinate

X - the x coordinate:
L - left boundary of the object
C - center of the object
R - right boundary of the object

Y - the y coordinate:
T - top boundary of the object
C - center of the object
B - bottom boundary of the object

Special:
UN  - don't change the corresponding x or y boundory of new element.
REL - If this bit is cleared, target coordinates is used from location of view.

insets - Determines the insets of this view in relation to the side of rectangle.
When mode along X axis is X_RR or X_LR added view shifts to the left. Otherwise it shifts to the right for the rest of modes.
When mode along Y axis is Y_BB or Y_TB added view shifts to the up. Otherwise it shifts to the down for the rest of modes.

public void add(View v)

Adds the view to the children list and corrects rectangle of composite view bound. The location of view is copied from view location

Parameters:

v - the added view

public View elementAt(int index)

Returns the view at the specified index.

Parameters:

an - index into this composite view.

Returns: the view at the specified index.

public Rectangle getBounds()

Returns rectangle bound of this composite view

Returns: rectangle bound of this composite view

public Enumeration getChildren()

Returns an enumeration of the views of this composite view.

Returns: an enumeration of the views of this composite view.

public View getDeepestActive(Point pt)

Returns deepest view in tree hierarchy, that has View.ACTIVE state and intersects the specified point.

Parameters:

pt - specified point

Returns: deepest view in tree hierarchy, that has View.ACTIVE state and intersects the specified point.

public Point getLocation()

Returns the location of this Rectangle bound.

Returns: the location of this Rectangle bound.

public void insert(View v, int i)
             throws java.lang.ArrayIndexOutOfBoundsException

Inserts view in specified position.

Parameters:

Parameters:

g2 - specified Graphics2D.

public boolean remove(View v)

Removes specified view from composite view

Parameters:

v - specified view

Returns: true if view is removed or false otherwise.

public void scale(double sx, double sy)

Scales all children of container in relation to old values.

Parameters:

sx - the factor by which coordinates are scaled along the X axis direction
