Drawing Shapes Bottom Right To Top Left

Mar 17, 2014

I am having issues with drawing shapes from bottom right to top left.

Issue:

- g.drawRect() will show like I am calling g.fillRect()
- other shapes will not even show the shape in that area

Needs:

- g.drawSHAPE needs to show and not be filled unless I have my fill checkbox selected

The Program:

- Create a JFrame with a draw panel and a component panel
- have a combobox with shapes that, when selected, will draw that shape in the draw panel
- have a button that, when clicked, will launch JColorChooser to change the color of the drawn shape (draw panel is set to black)
- have a checkbox that, when checked, fills the shape
- have mouse listeners to adjust X and Y and will instantly update the shapes size to where you drag/click/press/release

Code for my drawRect():

Java Code:

// if statement to check if mouse drag X is less than starting X
if(x2 <= x){
if(emptyORfill.isSelected()) // emptyORfill is my JCheckBox
g.fillRect(x2, y, x-x2, y2-y); // x-x2 is the same as Math.abs(x2-x)
else
g.drawRect(x2, y, x-x2, y2-y);

[Code] .....

This is just for my Rectangle. This will show a filled rectangle when both mouse drag X and Y are less then the starting X and Y. If I take this fully functional code and adapt it to drawRoundRect(), the round rectangle wont even show the shape when mouse drag X and Y are less than the starting X and Y but will be fine if one or the other is less than the starting X or Y. NOTE: This same exact code worked on my classmates laptop in her program, but in my program on her laptop it did not. She took out the "else" in the else if's and just made them if statements all the way down and it worked on her laptop in my program, but the same "fix" did not work on my pc.

My mouse listener just sets X and Y values in my Shape class that updates my shape methods. I have an item listener for my comboBox that sets default values when a new selection is made and enables/disables editable on my fill checkbox for certain shapes. My action listener looks for the button click and the checkBox click.

Draw From Bottom Of Bounds?

May 26, 2014

I 'm trying to draw a button by resizing a simple button background image to fit the size of the text. Everything works well except for the actual drawing of the string. The y value that I give the Graphics object designates the baseline, however I would like to draw the the string above the y. So that the image below doesn't happen.

I gave the graphics object the y of the bottom of the "P" and would instead like to give it the value of the bottom of the "y". Is there a way to do that by reading the String's bounds or something, or is there a way to get the Graphics object to use the passed y value as the definite bottom of the String?

Finding Path Through 2D Array From Top To Bottom?

Apr 20, 2015

I have a 2D array that is of type int[][]. it is populated with 1's and 0's. I need to create a method that allows me to search from the top row finding a possible path to the bottom--the path is a path of connecting cells containing 1. I need to create an array that stores the cells that are needed to be searched. When the search carries out, for each cell stored it needs to check the cells to the left, right, below and above the current cell.

I also need to create a variable to store the current cell. I thought initially it would be an int but it can't be because it needs to hold the the index of the current cell. and any of the cells searched that are an immediate neighbour of the current cell are added to the storage array.

I have these instructions but I am having trouble converting into code

Finding a path through vegetation from the top row to the bottom row: The idea is we will start from a cell in the top row and advance below for as long as we can. Since we are still not done exploring a cell until we have explored ALL it’s vegetation neighbors, we will add the cell to an array of cellsToExplore and only come back to it if the current cell we are examining is fully explored. Here is pseudo-code of the algorithm !

• Create array cellsToExplore (what size should this array be?)!

• Create an integer count that stores the number of cells in cellsToExplore!

• Go through the top row and add ALL vegetation cells to cellsToExplore!

• Create a variable to store currentCell we are exploring and set it to null.!

• while count > 0 do!

- set currentCell to the last cell in cellsToExplore (last cell added to the array).!

- label currentCell as burning vegetation!

- If the currentCell is on the bottom row then we return true (we found the path).!

- if the cell below currentCell is vegetation then add the cell below to the cellsToExplore array.!

- else if cell to the right of currentCell is vegetation then add the cell to the right to cellsToExplore!

- else if cell to the left of currentCell is vegetation then add the cell to the left to cellsToExplore!

- else if cell above the currentCell is vegetation then add the cell above to cellsToExplore.!

- else remove the currentCell from the cellsToExplore (we are done with this cell). !

• Return false!

Return Height Of Heap Of Sand In Bottom Of Hourglass

Nov 18, 2014

I am working on program and have been struggling to get around step 5 and 6 given below.

I have got on with the first couple of points. Where to begin with steps 5 and 6.

Java Code:

class Hourglass {
int height;
int bottomHalf;
public Hourglass (int h) {
height =h;
}
public Hourglass (){
height=3;
}

/*Write a method dropGrain that simulates one grain of sand falling into the bottom half of the Hourglass. If all the sand is already at the bottom before a grain is dropped, this method should cause the hourglass to be flipped, meaning that all the sand will be in the top again. Then, one grain of sand should fall. */

//Hint: this method can be quite short. All you need to do is update one attribute.

public void dropGrain(){
}

/*Write a method getHeapHeight() which returns the height of the heap of sand in the bottom of the hourglass.

Hint: a triangle of height h contains h*h grains (=1+3+5+...+h).

So determining the height when the amount of sand in the bottom half is a square (1,4,9,16,...) is easy. Think about what happens if the amount of sand is not exactly a square.*/

public int getHeapHeight() {
} mh_sh_highlight_all('java');

Paint Window Moving Picture From Bottom To Top Diagonally

Sep 30, 2014

PaintWindow pw = new PaintWindow();
Random rand = new Random();
ImageIcon image = new ImageIcon("C:/Users/Ghostkilla/Desktop/gubbe.jpg");
setWidth(pw.getBackgroundWidth());
int height = pw.getBackgroundHeight();

[Code] ....

If you run this code it will move a picture from right to left and hit the left wall and then go to right again leaving the window (It stops there). I want to make so it hits left and then right wall continuously till someones close the window. So basically I am using a for loop to make it go left right all the time.

How to make so the picture moves from bottomleftcorner to toprightcorner diagonally without leaving the window.

How To Get Random Shapes To Generate Automatically

Aug 31, 2014

I am trying to get random shapes to generate automatically. I was able to get just three shapes to generate but nothing random. When I added the random code now only the frame shows up and no shapes. I also keep getting an error with frame.setVisible(true). It says identifier expected. Here is what I have so far:

Main program:

import javax.swing.*;
import java.awt.*;
import java.util.Random;
public class ShapeGen {
public static void main(String [] args) {
//Create window and set title
draw panel = new Draw();

[Code] ....

This is the draw program to generate random shapes:

import javax.swing.*;
import java.awt.*;
import java.util.Random;
public class draw extends JPanel {
public draw(Color backColor) {
setBackground(backColor);

Calculating Areas Of Geometric Shapes

Oct 21, 2014

Write a class that has three overloaded static methods for calculating the areas of the
following geometric shapes:

• circles -- area = π*radius^2 (format the answer to have two decimal places)
• rectangles -- area = width * length
• trapezoid -- area = (base1 + base2) * height/2

Because the three methods are to be overloaded, they should each have the same name , but different parameters (for example, the method to be used with circles should only take one parameter , the radius of the circle).

Demonstrate the methods in a program that prints out the following areas, each on a separate line:

• the area of a circle with radius 3
• the area of a rectangle with length 2 and width 4
• the area of a trapezoid with base lengths 3 and 5 and height 5

SAMPLE RUN #1
--- Prompts For Keyboard/Console/Standard Input ---
Inputs
Outputs
--- Monitor/Console/Standard Output ---
28.27
8.0
17.5

What The Console Looks Like In An Interactive Session:
(Note: this combines standard input with standard output )

>java Area
28.27
8.0
17.5

THIS IS MY CODE

import java.util.*;
public class Area {
public static double area(double radius)
{
return (double)(Math.PI*Math.pow(radius,2));
}
public static int area(int length, int breadth)

Swing/AWT/SWT :: Append Always Visible JTable Footer At The Bottom Of Table

Nov 27, 2014

I am building a little application for personal use where I can track my finance. Now, what I would like to get is an always visible JTable "footer" OR horizontal space field attached to the bottom of the window. The idea is that scrolling down/up wouldn't affect it's visibility(like JTable header). Might a picture tell a thousand words: see attachment.

I am wondering, maybe JTable OR TableModel class has a property to solve this problem(I haven't found any)? Or shall I make another ScrollPane/JPanel? Which path of search shall I pursue?

Swing/AWT/SWT :: Moving Image Left Or Right

Mar 11, 2014

I can't find any resource on the net about a simple Java code just to move a gif image left or right. I've already accomplished the up, down, and center and they're working fine, thus, I'm still struggling with moving the image left or right. Here's the code.

public class MoveIt extends Applet implements ActionListener
{
private Image cup;
private Panel keypad;
public int top = 10;
public int left = 10;

[Code] ....

I remember in Visual BASIC it's easily achieved by NameOfImage.left = NameOfImage.left - 10 to move left and NameOfImage.left = NameOfImage.left + 10.

Setting Left And Right Node Values

May 6, 2014

I am getting errors when I try setting left and right values (which are String types) for my tree.I tried doing something like:

Node node = new Node("Is it human?", null, null);
node.getLeft().setNode("Is it Zelda?");//the first left Q
node.getRight().setNode("Is it Kirby?");//the first right Q

but that gives me a runtime error of "java.lang.NullPointerException" which points to the line 2. I also tried this:

Node node = new Node("Is it human?", null, null);
node.setLeft(setNode("Is it Zelda?"));//the first left Q
node.setRight(setNode("Is it Kirby?"));//the first right Q

but that gives me another error, pointing to the setNode for both lines 2 and 3,plus it wouldnt make sense since both setLeft and setRight takes in Node types, not String types.

Here is my Node class:

public class Node {
private Node leftPt, rightPt;//left and right pointers for Node
private String node, left, right;
public Node(String node, Node leftPt, Node rightPt){
this.node = node;
this.leftPt = leftPt;
this.rightPt = rightPt;

We're learning printf with JGrasp as the environment at the moment. Heres the problem.

I have a string as this:

String header1 = new String ("Caswell Catering and Convention Service");

as for the printf line, its this:

System.out.printf ("%-5s/n", header 1);

The output is right justified no matter the use of the "-" or without and I can't seem to find the correct thing to do to make it left justified.

Create Compound Shapes / Paths In JavaFX?

Apr 28, 2015

Is there some way to create compound shapes/paths in JavaFX?

For the record I'm not implying the use of the methods intersect, subtract, or union. These produce other shapes. A compound shape/path is one that has a knockout of some sort. For instance, a circle within a circle, such as in a 2d donut shape. Alternatives do not include a circle with a thick stroke nor an overlayed circle with the background color. Specifically, JavaFX supports the FillRule, in the case of the Path object. However, there doesn't appear to be an "add" method as there was in the Area shape in Swing.

JPanel Class That Creates Left And Right Panel

Feb 12, 2015

I have a JPanel class that creates a left panel and a right panel. the left panel and right panel both have one button each. What I’m trying to accomplish is when I click on the button in the left panel that it updates the button in the right panel. I have to do this without changing anything in the right panel.Basically I have to have LeftPanel have a way to keep track of an instance of RightPanel and I would have to do this through the JPanel class. But I have no clue where to begin on even accomplishing this.
