ClickableURL class for paint

Here is the class

Code:: import java.awt.*;
import java.awt.event.MouseEvent;
import java.awt.font.TextAttribute;
import java.awt.font.TextLayout;
import java.awt.geom.Rectangle2D;
import java.text.AttributedString;

public class ClickableURL
{
private String url;
private String shortName = null;
private int x;
private int y;
private Point mouse = new Point(-1, -1);
private Rectangle2D hoverArea = new Rectangle(-1, -1);
private static final Font font1 = new Font("Arial", Font.ITALIC, 13);
private static final Color white = new Color(255, 255, 255);
private static final Color grey = new Color(150, 150, 150);

/**
* Creates a new ClickableURL
*
* @param url the url to open on click
* @param shortName the name to display the URL as
* @param x the x co-ord to draw at
* @param y the y co-ord to draw at
*/
public ClickableURL(String url, String shortName, int x, int y) {
this.url = url;
this.shortName = shortName;
this.x = x;
this.y = y;
}

/**
* Creates a new ClickableURL
*
* @param url the url to open on click and display name
* @param x the x co-ord to draw at
* @param y the y co-ord to draw at
*/
public ClickableURL(String url, int x, int y) {
this.url = url;
this.x = x;
this.y = y;
}

public void repaint(Graphics2D g) {
String name = (shortName != null) ? shortName : url;
AttributedString as = new AttributedString(name);
as.addAttribute(TextAttribute.UNDERLINE, TextAttribute.UNDERLINE_ON, 0, name.length() - 1);
as.addAttribute(TextAttribute.FONT, font1);
Rectangle2D bounds = font1.getStringBounds(name, g.getFontRenderContext());
hoverArea = new Rectangle(x,
y - (int) bounds.getHeight(),
(int) bounds.getWidth(),
(int) bounds.getHeight());
if (hoverArea.contains(mouse)) {
g.setColor(grey);
}
else
g.setColor(white);
new TextLayout(as.getIterator(), g.getFontRenderContext()).draw(g, (float) x, (float) y);
}

public void mouseMoved(MouseEvent mouseEvent) {
mouse = mouseEvent.getPoint();
}

public void mouseClicked(MouseEvent mouseEvent) {
if (hoverArea.contains(mouseEvent.getPoint())) {
util.openURL(url);
}
}
}

Now to use that create a new instance in your script.
Ex

Code:: ClickableURL test = new ClickableURL("http://google.com/", "Google", 50,50);

To use them you will have to put implements MouseMotionListener, MouseListener in your script declaration ex

Code:: public class scriptname extends ActiveScript implements MouseMotionListener, MouseListener

Then implement all the methods required by the interfaces

Then in mouseClicked and mouseMoved you will need to call the methods in the ClickableURL
ex

Code:: public void mouseMoved(MouseEvent e) {
threadURL.mouseMoved(e);
for (ClickableURL url : urls)
url.mouseMoved(e);
}

is how I do it in UberDungeon, urls is an ArrayList I store most of my URL classes in.

Then do the same in your onRepaint() function
Except call .repaint(Graphics 2D g);

Code:: threadURL.repaint(g);
for (ClickableURL url : urls)
url.mouseMoved(g);

Awesome, I can see how this would be useful, for feedback and such.

Sweet. But why would you need the /**param stuff? Why would you need to view the Javadoc?
Otherwise, very sweet. I'll be using this soon Very Happy

Creating JDocs is good practice, I do it for the majority of my functions, especially since UberDungeon has an API so I am required to JDocs the majority of the functions.
