MikoBoyzzz - OU812

Hi peeps, I will be at these locations over the weekend..



8:00 am - 12:00 pm (University of the East Java Tutorial Track 2).



6:00 pm - 10:00 pm (STI Java / J2ME related discussions ) .

Hello Class,


I want you to review Part2 to Part 4 of the Java tutorial Site that I gave... We will be doing the Sample programming this coming saturday..Considering that the schedule for the 21st was moved to September....

Also be familiar with Jcreator because that will be our default IDE at this moment...

And tell ur friends and schoolmates about how wonderful the world is gonna be with JAVA.. :D

Try These Swing Examples..

-------------------------
InvisibleTreeModel.java

-------------------------

/* (swing1.1) */
import javax.swing.tree.*;
/** * @version 1.0 01/12/99 */public class InvisibleTreeModel extends DefaultTreeModel {
protected boolean filterIsActive;
public InvisibleTreeModel(TreeNode root) { this(root, false); }
public InvisibleTreeModel(TreeNode root, boolean asksAllowsChildren) { this(root, false, false); }
public InvisibleTreeModel(TreeNode root, boolean asksAllowsChildren ,boolean filterIsActive) { super(root, asksAllowsChildren); this.filterIsActive = filterIsActive; }
public void activateFilter(boolean newValue) { filterIsActive = newValue; }
public boolean isActivatedFilter() { return filterIsActive; }
public Object getChild(Object parent, int index) { if (filterIsActive) { if (parent instanceof InvisibleNode) { return ((InvisibleNode)parent).getChildAt(index,filterIsActive); } } return ((TreeNode)parent).getChildAt(index); }
public int getChildCount(Object parent) { if (filterIsActive) { if (parent instanceof InvisibleNode) { return ((InvisibleNode)parent).getChildCount(filterIsActive); } } return ((TreeNode)parent).getChildCount(); }
}

----------------------
InvisibleNode.java
----------------------

/* (swing1.1) */
import java.util.*;import javax.swing.tree.*;
/** * @version 1.0 01/12/99 */public class InvisibleNode extends DefaultMutableTreeNode {
protected boolean isVisible;
public InvisibleNode() { this(null); }
public InvisibleNode(Object userObject) { this(userObject, true, true); }
public InvisibleNode(Object userObject, boolean allowsChildren , boolean isVisible) { super(userObject, allowsChildren); this.isVisible = isVisible; }
public TreeNode getChildAt(int index,boolean filterIsActive) { if (! filterIsActive) { return super.getChildAt(index); } if (children == null) { throw new ArrayIndexOutOfBoundsException("node has no children"); } int realIndex = -1; int visibleIndex = -1; Enumeration enum = children.elements(); while (enum.hasMoreElements()) { InvisibleNode node = (InvisibleNode)enum.nextElement(); if (node.isVisible()) { visibleIndex++; } realIndex++; if (visibleIndex == index) { return (TreeNode)children.elementAt(realIndex); } } throw new ArrayIndexOutOfBoundsException("index unmatched"); //return (TreeNode)children.elementAt(index); }
public int getChildCount(boolean filterIsActive) { if (! filterIsActive) { return super.getChildCount(); } if (children == null) { return 0; } int count = 0; Enumeration enum = children.elements(); while (enum.hasMoreElements()) { InvisibleNode node = (InvisibleNode)enum.nextElement(); if (node.isVisible()) { count++; } } return count; }
public void setVisible(boolean visible) { this.isVisible = visible; } public boolean isVisible() { return isVisible; }
}
