How To Draw Multiple Graphics Inside One JPanel Using Multiple Classes

May 5, 2015

I'm very new to Java, and I am creating a program that takes multiple user input to create one face. I have a class for the eyes, nose, lips, and headshape. For some reason, my program is not drawing the graphics. ***for question purposes, I have only included my head shape class and my test class****

my "test" class:

Applets :: JApplet That Ask User For Points And Draw A Line From Said Points

Nov 6, 2013

This is what he wants: He wants us to prompt the user to input x values and y values (that will be entered into an array when clicking one of the two buttons (this one will say: Add point)). When they click the second button (draw lines), it should take all the points and draw a line that connects all the points together using a method that we write. In the method we have to call the paint method up which the lines will be drawn. The lines drawn should be touching every point added. It shouldn't have parameters. It will also use Graphics painter = getGraphics(); We can't use frames either.

I have everything up until the method understood.

How to write a method that will draw a line from points inputted that is called up in the action listener when the second button (draw lines) is pressed.

Swing/AWT/SWT :: Drawing A Semicircle Using Formula For The Equation Of A Circle

Sep 19, 2014

So Ive got to make a turtle on an image draw a semicircle that starts at the top of a circle and goes down and to the left, changing colors halfway through. I've got everything down, I can draw the turtles and make them do straight lines. My problem is more math related. I need to use the equation of a circle, give it points, and figure out how to write that code in java.

We use the equation for a circle: (x - a)^2 + (y - b)^2 = r^2

amanda.setName("amanda");
amanda.setShellColor(Color.BLUE);
amanda.setBodyColor(Color.RED);
amanda.setPenColor(Color.YELLOW);
amanda.setPenWidth(3);
amanda.forward();
amanda.turn(-90);
amanda.setPenColor(Color.BLUE);
amanda.forward(???);

the question marks are where I need to draw a line on an arc, like in the picture.

Swing/AWT/SWT :: Repaint Method Is Automatically Erasing Old Circle?

Feb 19, 2014

This code is shown to eliminate "smearing":

public void paintComponent (Graphics g) {
g.setColor(Color.white);
g.fillRect(0,0,this.getWidth(), this.getHeight());
g.setColor(Color.green);
g.fillOval(x, y, 40, 40);
}

I had done all the previous code (in my own style) and found that the background rectangle was either being redrawn on its own, or there was something else removing the old circles from the screen. I then typed in the code from the previous page exactly as it was, to see if I had some change in syntax that would cause this, and it did the same thing.

Here's my code:

import javax.swing.*;
import java.awt.*;
public class SimpleAnimation {
int x, y;
private static final int HEIGHT = 600;
private static final int WIDTH = 600;

[Code] .....

Is this because I'm using JRE7? I can't find any documentation that indicates the repaint() method has changed since Java 5.

Swing/AWT/SWT :: Iterating Through Objects To Draw On Panel?

Apr 23, 2014

I currently have the code set up to iterate through objects and keep track of them but how do I do the same and draw the objects on the panel window? I'm confused on what to do and how to start it.

Here's the code I have so far, the 'Car' which I want to draw extends to another class which extends to GameObject. I currently have a 'draw()' method under the 'Car' class but nothing in the 'draw()' method yet. From what I understand i'm suppose to have a 'draw()' method under 'GameObjects' class also?

public class MapView extends JPanel implements IObserver, ActionListener{
JPanel myPanel;
private Timer timer = new Timer(5, this);
int x = 0;
int moveX = 2;
public MapView(){
super.setBorder(BorderFactory.createTitledBorder("Map:"));

[code]....

Mostly I don't understand how to go through the iterator again to paint the objects. Wouldn't I need to put another iterator under 'paintComponent()' or can it be done under 'update()' ?

how to get some shapes from the GameObjects onto my panel.

JavaFX 2.0 :: Horizontal Stacked Bar Chart

Sep 14, 2014

Using the sample, I tried to create a horizontal stacked bar chart, but it didn't render correctly.  Only a sliver of one bar shows and cosmetically the bar's rounded corners are at the top instead of the right side.
 
    @Override
    public void start(Stage primaryStage) {
        String austria = "Austria";
        String brazil = "Brazil";
        NumberAxis xAxis = new NumberAxis();
        xAxis.setLabel("Value");
        xAxis.setTickLabelRotation(90);

[Code] ....
 
Oddly, if I change the second series to this, then only one bar shows:
 
        series2.getData().add(new XYChart.Data(10, austria));
        series2.getData().add(new XYChart.Data(15, brazil));
