Я работаю над java gui с программированием сокетов. Я хочу создать jpanel на jframe с параметрами, которые я посылаю с сервера, и создавать случайные фигуры в jpanel.Я использовал этот ресурс для рисования фигур:
https://github.com/AugustBrenner/Random-Draw-Shape/blob/master/DrawPanel.java
мой код в jframe:
public void starteGame(String received) {
gamers.setText(received);
String[] mParsed = received.split(" ");
boolean filled = true;
int width = Integer.parseInt(mParsed[2]);
int height = Integer.parseInt(mParsed[1]);
int x1 = Integer.parseInt(mParsed[3]);
int y1 = Integer.parseInt(mParsed[4]);
int x2 = Integer.parseInt(mParsed[5]);
int y2 = Integer.parseInt(mParsed[6]);
int randomShape = Integer.parseInt(mParsed[7]);
Color firstColor = new Color(Integer.parseInt(mParsed[8]), true);
Color secondColor = new Color(Integer.parseInt(mParsed[9]), true);
boolean cyclic = Boolean.parseBoolean(mParsed[10]);
switch (randomShape) {
case 1:
// add the line to the list of lines to be displayed
shape = new MyPolygon(x1, y1, x2, y2, firstColor, filled);
break;
case 2:
shape = new MyRectangle(x1, y1, x2, y2, firstColor, filled);
break;
case 3:
shape = new MyOval(x1, y1, x2, y2, firstColor, filled);
break;
}
jPanel2=new PanelDraw(width,height,x1,y1,x2,y2,firstColor,secondColor,
randomShape,shape,cyclic);
}
And my PanelDraw is;
public class PanelDraw extends JPanel implements MouseMotionListener {
private Random randomNumbers;
private MyShape shape;
int x1;
int y1;
int x2;
int y2;
Color firstColor;
Color secondColor;
int width;
int height;
// generate random shape
int randomShape;
boolean cyclic ;
// constructor, creates a panel with random shapes
public PanelDraw(int width, int height, int x1, int y1, int x2, int y2,
Color first, Color second, int randomS,MyShape shape ,boolean cyclic) {
this.width = width;
this.height = height;
// generate random coordinates
this.x1 = x1;
this.y1 = y1;
this.x2 = x2;
this.y2 = y2;
// generate a random color
this.firstColor = first;
this.secondColor = second;
// generate random shape
randomShape = randomS;
this.shape=shape;
this.cyclic=cyclic;
//setBackground( Color.BLACK );
} // end DrawPanel constructor
public void mouseMoved(MouseEvent event) {
}// end mouseMoved
public void mouseDragged(MouseEvent event) {
} // end method
// for each shape array, draw the individual shapes
@Override
public void paintComponent(Graphics g) {
//initialize filled boolean to true;
boolean filled = true;
// initialize random cyclic boolean
// draw the shape
Graphics2D g2d = (Graphics2D) g; // cast g to Graphics2D
g2d.setPaint(new GradientPaint(x1, y1, firstColor, x2, y2,
secondColor, cyclic));
shape.draw(g2d);
g2d.dispose();
// shapeCount++;
try {
Thread.sleep(700);
} catch (Exception e) {
}
repaint();
} // end method paintComponent
} // end class DrawPanel
панельне появляется, когда моя функция работает, а случайные фигуры не отображаются.Вы можете мне помочь?
