Changer la taille de mon outil de dessin
Bonjour,
Je souhaite pouvoir dessiner dans un JPanel en changeant changer la taille de mon "crayon" en cliquant sur les boutons small et large. Voici où j'en suis:

public Paint(){

buttonLarge.addActionListener(e->p.setCrayonSize(8));
}
class sizeCrayon implements ActionListener{
private final int valeur;
public sizeCrayon (int valeur){
this.valeur=valeur;
}
public void actionPerformed(ActionEvent e) {
p.setCrayonSize(valeur);
}
}
public static void main(String[] args) {
Paint p = new Paint();
p.setVisible(true);
}

private int pointCount=0;
private int currentValeur=4;
private int valeur;
//array of 10000java.awt.Point references
private DrawingPoint []points = new DrawingPoint [10000];
public PanelPaint(){
addMouseMotionListener(
new MouseMotionAdapter(){
public void mouseDragged(MouseEvent event){
if(pointCount<points.length){
points[ pointCount ] = new DrawingPoint (event.getPoint(), valeur); // find point
++pointCount; // increment number of points in array
repaint(); // repaint JFrame
} // end if
} // end method mouseDragged
}
);
}
public class DrawingPoint {
public int x;
public int y;
public int valeur;
public DrawingPoint(Point point, int valeur) {
this.x=point.x;
this.y=point.y;
this.valeur=valeur;
}
}
// draw ovals in a 4-by-4 bounding box at specified locations on window
public void paintComponent( Graphics g )
{
super.paintComponent( g ); // clears drawing area
// draw all points in array
for ( int i = 0; i < pointCount; i++ ){
g.fillOval( points[i].x-2, points[i].y-2, currentValeur, currentValeur );}
} // end method paintComponent
public void setCrayonSize(int valeur){
currentValeur=valeur;
}
} // end class PaintPanel |
Le problème est que si je clique sur large (par exemple), tous mon dessin sera agrandi, alors que je voudrais pouvoir dessiner des lignes de tailles diverses.
Merci :)
