[JAVA2D] tooltiptext

[Braun-Friedman, David]

Im hoping that someone can give me some insight on the following issue:   I am writing a java 2D imaging application that allows the user to annotate crosses on top of a jpeg image (among allowing other image manipulations as well).  I have been trying to implement a tooltip for each of the annotations so that it will display some info about that particular annotation.  To do so, I created a class called crossAnnotation that extends JComponent, thus allowing me use the setToolTipText method for each crossAnnotation object.  The problem however, is that when I add the crossAnnoation(JComponent) obect to the imageCanvas(JPanel) where the image is drawn my whole program freezes. The program can’t seem to handle the crossAnnotation being added to the imageCanvas as JComponent.  Anyone know why? or maybe how I can implement the toolTip in some other way (but as far as I can se toolTip only works with JComponent)?  Any help would be greatly appreciated.     Thanks Dave   Here’s my code for crossAnnotation     public class CrossAnnotation extends JComponent{       private GeneralPath p;     private double drawX, drawY;     private double magFactor;       private Graphics2D g2D;     private Spot2GPlate spot;       public CrossAnnotation(double drawX, double drawY, double magFactor, Graphics2D g2D, Spot2GPlate spot) {         //addMouseListener(this);         this.drawX = drawX;         this.drawY = drawY;         this.magFactor = magFactor;         this.g2D = g2D;         this.spot = spot;         this.setToolTipText("aupa!!!!");         //makeCross();     }       public void make(int swidth, int sheight, double magFactor, double width, double height){        p = new GeneralPath(GeneralPath.WIND_NON_ZERO);        p.moveTo(0, -sheight);        p.lineTo(0, sheight);        p.moveTo(-swidth, 0);        p.lineTo(swidth, 0);        //this.setSize(swidth*2, sheight*2);     }       public void setColorandDraw(int i, SpotList spotList, int gelType, boolean annotatedCanvas){       if(i < spotList.getNumAnnotated())       {           if ((spot.getSpotExpressionTarget() - spot.getSpotExpressionControl()) > 0)           {             if(gelType == 1)                 g2D.setColor(Color.red);             else             {                 g2D.setColor(new Color(0,150,0)); }           }           else           {             if(gelType == 1)             {                 g2D.setColor(new Color(0,150,0)); }             else                 g2D.setColor(Color.red);           }             this.drawAnnotation(drawX, drawY);       }       else       {         if(spotList.size() > spotList.getNumAnnotated())         {             if(annotatedCanvas)                 g2D.setColor(Color.red);             else                 g2D.setColor(new Color(0,150,0));               this.drawAnnotation(drawX, drawY);         }       }     }       public void setAnnotationLabel(int canvasH){       //System.out.println("canvasH: "+canvasH);       g2D.setColor(Color.blue);       Font f = new Font("Dialog", Font.PLAIN, (int)(12*magFactor));       g2D.setFont(f);       //g2D.translate(drawX, drawY);       g2D.drawString(spot.getSpotIdentifier(), (int)(drawX-(15*magFactor)), (int)(drawY-((canvasH/36)*magFactor)));       //g2D.dispose();     }       public void drawAnnotation(double drawX, double drawY){         //g2D.setColor(Color.red);         g2D.translate(drawX, drawY);         g2D.draw(p);         g2D.translate(-drawX, -drawY);                         //g2D.dispose();     }           /*public void mouseClicked(MouseEvent e) {         //To change body of implemented methods use File | Settings | File Templates.     }       public void mouseEntered(MouseEvent e) {         System.out.println("mouseEntered");         this.setToolTipText("x: "+drawX+" y: "+drawY);//To change body of implemented methods use File | Settings | File Templates.     }       public void mouseExited(MouseEvent e) {         //To change body of implemented methods use File | Settings | File Templates.     }       public void mousePressed(MouseEvent e) {         //To change body of implemented methods use File | Settings | File Templates.     }       public void mouseReleased(MouseEvent e) {         //To change body of implemented methods use File | Settings | File Templates.     } */   }   =========================================================================== To unsubscribe, send email to [EMAIL PROTECTED] and include in the body of the message "signoff JAVA2D-INTEREST".
