| Methods Summary |
|---|
| public void | addArea(javax.swing.text.AttributeSet as)Defines a region of the Map, based on the passed in AttributeSet.
if (as == null) {
return;
}
if (areaAttributes == null) {
areaAttributes = new Vector(2);
}
areaAttributes.addElement(as.copyAttributes());

| protected javax.swing.text.html.Map$RegionContainment | createRegionContainment(javax.swing.text.AttributeSet attributes)Creates and returns an instance of RegionContainment that can be
used to test if a particular point lies inside a region.

| protected static int[] | extractCoords(java.lang.Object stringCoords)Creates and returns an array of integers from the String
stringCoords. If one of the values represents a
% the returned value with be negative. If a parse error results
from trying to parse one of the numbers null is returned.

| public javax.swing.text.AttributeSet | getArea(int x, int y, int width, int height)Returns the AttributeSet that contains the passed in location,
x, y. width, height
gives the size of the region the map is defined over. If a matching
area is found, the AttribueSet for it is returned.
int numAttributes = (areaAttributes != null) ?

}
}
}
return null;
|
| public javax.swing.text.AttributeSet[] | getAreas()Returns the AttributeSets representing the differet areas of the Map.
int numAttributes = (areaAttributes != null) ? areaAttributes.size() :
0;
if (numAttributes != 0) {
AttributeSet[] retValue = new AttributeSet[numAttributes];
areaAttributes.copyInto(retValue);
return retValue;
}
return null;
|
| public java.lang.String | getName()Returns the name of the Map.
return name;
|
| public void | removeArea(javax.swing.text.AttributeSet as)Removes the previously created area.
if (as != null && areaAttributes != null) {
int numAreas = (areas != null) ? areas.size() : 0;
for (int counter = areaAttributes.size() - 1; counter >= 0;
