Java Utililty Methods Rectangle Create Parse

Rectangle decodeBounds(String sBounds)
Decode the comma separated values stored in sBounds.

int index;
int ii;
int theValue[] = new int[4];
String tmpString;
String restString = sBounds;
for (ii = 0; ii < 4; ii++) {
 theValue[ii] = 0;
try {
 for (ii = 0; ii < 4; ii++) {
 index = restString.indexOf(","); 
 if (index > 0) {
 tmpString = restString.substring(0, index);
 restString = restString.substring(index + 1);
 } else {
 tmpString = restString; 
 restString = null; 
 theValue[ii] = Integer.valueOf(tmpString).intValue();
} catch (Exception ee)
return new Rectangle(theValue[0], theValue[1], theValue[2], theValue[3]);

Rectangle getRectangle(Map bounds)
Extract a rectangle which has been serialised to JSON as x,y,w,h.

return new Rectangle(getInt(bounds, "x"), getInt(bounds, "y"), getInt(bounds, "width"),
 getInt(bounds, "height"));

Rectangle getRectangle(Preferences prefs, String sName, int iDefaultWidth, int iDefaultHeight)
reads a rectangle from the preferences

final Preferences node = prefs.node(sName);
final int x = node.getInt(PREFS_KEY_RECTANGLE_X, 0);
final int y = node.getInt(PREFS_KEY_RECTANGLE_Y, 0);
final int width = node.getInt(PREFS_KEY_RECTANGLE_WIDTH, iDefaultWidth);
final int height = node.getInt(PREFS_KEY_RECTANGLE_HEIGHT, iDefaultHeight);
return new Rectangle(x, y, width, height);

Rectangle getRectangle(Properties prop, final String key, final Rectangle def)
get Rectangle

try {
 final Rectangle result = new Rectangle();
 result.x = getInteger(prop, key.concat("-x"));
 result.y = getInteger(prop, key.concat("-y"));
 result.width = getInteger(prop, key.concat("-w"));
 result.height = getInteger(prop, key.concat("-h"));
 return result;
} catch (Exception e) {
...

Rectangle getRectangle(String rectStr)
Return a Rectangle from a string of "x,y,w,h".

try {
 StringTokenizer st = new StringTokenizer(rectStr, ",");
 int x = Integer.parseInt(st.nextToken().trim());
 int y = Integer.parseInt(st.nextToken().trim());
 int w = Integer.parseInt(st.nextToken().trim());
 int h = Integer.parseInt(st.nextToken().trim());
 return new Rectangle(x, y, w, h);
} catch (Exception e) {
...

Rectangle newRectangle(int x1, int y1, int x2, int y2)
creates a rectangle out of two points.

final int x = Math.min(x1, x2);
final int y = Math.min(y1, y2);
final int w = Math.abs(x1 - x2 + 1);
final int h = Math.abs(y1 - y2 + 1);
return new Rectangle(x, y, w, h);

String rectangleToString(Rectangle r)
rectangle To String

StringBuilder buf = new StringBuilder();
buf.append(String.valueOf(r.x));
buf.append(",");
buf.append(String.valueOf(r.y));
buf.append(",");
buf.append(String.valueOf(r.width));
buf.append(",");
buf.append(String.valueOf(r.height));
...

String rectangleToString(Rectangle r)
rectangle To String

return r.x + "," + r.y + "," + r.width + "," + r.height;

String rectangleToString(Rectangle rectangle)
Convert a Rectangle object to a comma separated string in the format of x,y,width,height.

StringBuffer buf = new StringBuffer(String.valueOf(rectangle.x));
buf.append(',');
buf.append(String.valueOf(rectangle.y));
buf.append(',');
buf.append(String.valueOf(rectangle.width));
buf.append(',');
buf.append(String.valueOf(rectangle.height));
return buf.toString();
...

void storeBounds(String name, Window window)
Call this to record the fact that the window/dialog with the given name has moved.

dialogGeometries.put(name, window.getBounds());
