Java 2D Drawing Application - Shape Should Be Drawn As Mouse Is Dragged
Nov 4, 2014
Java 2D Drawing Application. The application will contain the following elements:
a) an Undo button to undo the last shape drawn.
b) a Clear button to clear all shapes from the drawing.
c) a combo box for selecting the shape to draw, a line, oval, or rectangle.
d) a checkbox which specifies if the shape should be filled or unfilled.
e) a checkbox to specify whether to paint using a gradient.
f) two JButtons that each show a JColorChooser dialog to allow the user to choose the first and second color in the gradient.
g) a text field for entering the Stroke width.
h) a text field for entering the Stroke dash length.
I) a checkbox for specifying whether to draw a dashed or solid line.
j) a JPanel on which the shapes are drawn.
k) a status bar JLabel at the bottom of the frame that displays the current location of the mouse on the draw panel.
If the user selects to draw with a gradient, set the Paint on the shape to be a gradient of the two colors chosen by the user. If the user does not chosen to draw with a gradient, the Paint with a solid color of the 1st Color.
Note: When dragging the mouse to create a new shape, the shape should be drawn as the mouse is dragged.
I am trying to draw at my mouse a certain shape that I have set. I defined some shapes where they extend shape and draw circles and stuff. But when I click on panel it seems the paint doesnt put anything there. Debugger tells me shapes are saved though.
I have my paint application, i use the following mouse event to draw my shapes (mousePressed, mouseReleased, mouseDragged). Now after the user paint a circle for example, he must be able to drag the shape; to be able to do this. i think i must again implement the different mouse Events. I have done it and the drag is not working. How can i achieve this. can we implement multiple (mousePressed, mouseReleased, mouseDragged) in the same java class??
I'm following this tutorial![URL] I've copied over a lot of the code and also copied/pasted other parts! I understand how it works, but I can't figure out why the "X" or "O" won't paint onto the screen when the window is clicked on! Only a button is drawn when I click on the screen.
/* package tictactoe; import javax.swing.*; import java.awt.Image; import java.awt.event.MouseListener; import java.awt.event.MouseEvent; import java.awt.Toolkit;//look into this library
i would like to create a menu like below where if i clicked on "DRAW", a frame to draw will appear and when i clicked on animate, I can animate an object drawn. I tried on using JButton, but I donno how to customize the design n so I would like to know is there other ways so tat my menu will appear as below?
I'm using a BorderLayout, with 26 buttons to make up the alphabet from a keyboard. All the spacing looks great, but when you drag the screen out, everything gets jumbled. I would prefer to have everything stretch out, and keep the same positioning, or everything move towards the center still keeping the keyboard style positioning of the buttons but increasing the size of the window. Will a BorderLayout work for what I want, or should I try something else?
Currently to keep the buttons spaced apart I am keeping there preferred size to 25, and using horizontal and vertical struts to get the buttons positioned like I want.
This is how it is if I keep it the width and height 400, 400.

This is what happens when its stretched or shrunk.

This is an example of one of the ways I would prefer it
I am supposed to Write a program that prints a shape similar to the following shape. Maximize use of loops and minimize use of print statements.
.....* ....** ...*** ..**** ...*** ....** .....*
(without the "...")(i couldn't get it to stay in shape)
This is what i got so far:
Java Code: package assignment7;
public class Exercise3 { public static void main (String[] args) { for (int count =0; count < 4; count++) { for (int j=0; j < count+1; j++) [Code] ....
I've got a question about drawing animations in Java (SWT). I try to draw an animation of some process.
When i use canvas.redraw() it seems like program firstly erases everything that has been drawn and then draws again.
My program draws about 1000 of rectangles per time step so animation doesn't looks smooth - it blinks all the time and I can't avoid drawing that many rectangles.
Is there a way to make it look smoother (for example to paint new objects over old ones, without erasing them)?
I have a problem which can't solve it for 2 days search. I need to draw 3d shapes , i downloaded all packages and set an example code and run it ...

I use a program called eclipse. I want to know how to build a house with the program. We use a pen in java. It is a drawing tool. I dont know how to do it.
I decided to change the mouse cursor based on the theme of the game. This is the code that I wrote for the declaration of the cursor:
ImageIcon imageIcon = new ImageIcon ("cursor / cursor.gif"); Image img = imageIcon.getImage (); Toolkit t = Toolkit.getDefaultToolkit (); Cursor cursor = t.createCustomCursor (img, new Point (0,0), "cur"); this.setCursor (cursor);
Having to click on different JButton in the menu of the game, a few screens later, I have to manage something in particular, such as determining the point of clicks that allows the action to take place?
In particular I would like to change the point of hotspots. The size of 136x163 is cursor.gif

As you can see in the image I want to create the point of hotspots in the red dot of the image. How should I do to pass the correct coordinates in Point?

try to make a game in this code i am trying to make the basics i have made a mouse it should move the game code is

I'm creating a game called Mouse Trap and I'm having an issue with a graphic drawn using AWT. Basically, when the mouse collides with the cheese, I want the cheese to disappear, or call (cheese[i].hide()). However, the cheese does not appear. hide() works for all other objects that inherit from PFigure, but the cheese will not. It's created a major issue in my game, and basically the only task left to accomplish.I believe my problem lies within Cheese.java, method draw(). For example, if I replace it with an example drawing, this problem goes away!:
public void draw() { Graphics g = panel.getGraphics(); g.setColor(Color.blue); g.drawOval(x + width / 4 , y + 1, width / 2, height / 2);
[Code] ....
I have three classes below that most likely involve the problem, feel free to ask if you need the others.PFigure.java (This class cannot be changed as a requirement to my project)
import java.awt.*; public abstract class PFigure implements Comparable { protected int x, y; // Current position of the figure protected int width, height; // Drawn (displayed) this size protected int priority; // Can use to determine "winner" protected Panel panel; // Panel the figure lives on
I'm creating a card game and I'm having trouble getting a card gif to display. A card is drawn from an 52 card deck arraylist, and I then need to match that drawn card with the similarly named gif in an arraylist of card gifs, to display the gif on a card GUI. I have put my game, card, deck and graphical class below:
Card - public class Card { public String number; public String suit; public Card(String n, String s) { number = n; suit = s;
[Code] ....
The arrayList of card gifs (which contains all 52 gifs for the cards) is in the graphical class and my arrayList that contains the deck of cards in textual form (that I've imported from a textfile) is in deck. The names of the gifs in the gif arraylist are the same as the card names in my textual card arraylist (for example, 3h.gif is 3h in my card arraylist), so I believe I can use a .equals statement to match the card that has been drawn to the gif.
Here is what the gifs look like in their folder, which is an arraylist in my graphical class :
Here is what the drawn card looks like after the textual card arraylist has been shuffled:
The brown card in that image isn't the displayed card that has been drawn, it's just a graphical deck that I put in, I can't get the card that has been drawn on the GUI to display on the actual card frame, as you can see.
I am thinking of a project for my university the teachers liked it but I am not sure if its even possible.I am trying to make an andriod app. What I want to do is take a picture of a hand drawn logic circuit (having the AND, OR, NOT ... gates) recognize the gates, and make a circuit in the moblie and run it on all possible inputs.
For this I will have to make a simulator on mobile, that I dont think is the hard part. The problem is how could recognize the gates from a picture. Example of logical circuit is attached ( assume its hand drawn )..I found out that theres a edge detection plugin in java but still I dont think its enought to recognize the gates. Please share any algorithm or any technique or tools that I can use to make this thing.
So, I have this simple program that paints a string on JPanel using g2.drawString("Hello world", 40, 120). Basically, I want to be able to keep track of many strings on the JPanel at once. I'm not sure how to do this. For example, I would want to have an ArrayList of objects that keep track of these strings.
I want to be able to click-and-drag these strings so I will need to know there locations, etc.
Right now, using g2.drawString, it only draws the string. I want something like gw.draw(myStringObject).
I have tried running the java application without adding the site to site list in java security tab. But I get a sand box message as APPLICATION BLOCKED BY SECURITY SETTINGS. How to run the java application without adding the site to site list in java security tab.
I've written a java application with several classes all in the same .java file. It works just fine. Now, I've broken it up so that each class has its own .java file. Still works fine. My next step is to put those classes into a package, but I'm not about to get the program to run.The .java source files are all in /home/user/src
I've set the CLASSPATH to /home/user/src..All of the source files have "package com.myfirm.program" on the first line.I compiled the application with:
the compiler created the directory: /home/user/src/com/myfirm/program and put all of the .class files in there.So how do I get the program to run? if I run from /home/usr/src
java File1
I get: Exception in thread "main" java.lang.NoClassDefFoundError: File1 (wrong name: com/myfirm/program/Program)
why am I not getting a proper shape of "Leftarrow"? The result should look like the following (the system draws the arrow abnormally, so the beginning should a real ARROW:

here is the class:
Java Code: public class LeftArrow extends ShapeBase { private int lengthOfTail; private int widthOfArrowHead;
