how to draw directly to the monitor without a While loop

[Arturo Gamboa]

this idea has gone round round in my head, and i can figure it out..

how do i draw a simple image to the monitor without a loop.

the common way to draw an image to the monitor as i have seen so far, is inside a while loop( active rendering i think), otherwise it wont draw

while(expression){

Graphics.DrawSomething(arguments);

}

if i do it that way it get drew to the screen.

i want to know if thres a way to get something drawn out of a single sentence like the last one but wihout the loop.

Graphics.DrawImage

What GUI/Graphics library are you using? Swing? If so, then your best bet is to study the Sun/Oracle 2D Graphics tutorials.

Much luck!

thank you for the advice, i knew it could be done with 2D.
anyway, i have the curiosity if theres a way other than using Java 2d graphics.

I'm having a great deal of difficulty understanding just what you're asking here. It's kind of like asking if one could prepare dinner without using food. Can you give us more details regarding just what you're trying to do?

sorry for not explaining myself better.

ill do it more explicitly-

ill write down the the methods i know so far to draw an image:

1.- using paint method from inside the component(passive rendering):

class mycomponent extends  Component{

override paint(Graphics g)

super.paint();
//do drawing here
g.drawSomething

}

2.-using active rendereing(anywhere inside a while loop)

static main(){

Graphics g = mycomponet.GetGraphics();


while(true)

g.DrawSomething();


}

3.- and finally using Java2d graphics to draw on a bufferedimage which will be drawn on the monitor afterward(very similar to what i want)
definitly too much ado for painting an image

static void main(){



          JFrame jframe = new JFrame();
          jframe.setIgnoreRepaint(true);
        jframe.setUndecorated(true);

        GraphicsEnvironment localGraphicsEnvironment = GraphicsEnvironment.getLocalGraphicsEnvironment();
        GraphicsDevice device = localGraphicsEnvironment.getDefaultScreenDevice();
        GraphicsConfiguration gc = device.getDefaultConfiguration();


        device.setFullScreenWindow(jframe);
        device.setDisplayMode(new DisplayMode(640,480,16,75);

        jframe.createBufferStrategy(2);
        BufferStrategy buffer = jframe.getBufferStrategy();
        BufferedImage bufferedImage = gc.createCompatibleImage(640,480);


        
     Graphics2D g2 = bufferedImage.createGraphics();
    

      Image   image = new  ImageIcon("images/sonic.gif").getImage();
        g2.drawImage(image,10,10,null);


          Graphics G =  buffer.getDrawGraphics();
         G.drawImage(bufferedImage,10,10,null);
        if( !buffer.contentsLost() )
            buffer.show();




}

the thing i want to know if there is a more natural way to draw an image on the monitor;something like this or alike


Component contextcComponent
image image = myGetImage(url location);

Graphics g = contextComponent.Getgraphics();
g.drawImage(image,x,y,null);



//and ready. a simple image on the monitor. i have been surfing on the web but cant get any answer, maybe theres not any?
sorry if its still dificult to figure out what i want. your answers are very apreciated

I think what you're looking for is a JLabel with an Icon (probably ImageIcon)

I know it's late (I seem to have been very busy over the weekend) but Ithink thisought to move to our GUIs forum.

Beware of drawing to the screen; that can take much much longer than the loop and it is possible for the loop to re-start before drawing is completed.
