Passing Graphics object

Trying to do an exercise which states that methodX should draw a square of a specific size according to a value input by the user.
Unsure about the following
"methodX should be called from the applets paint method and should be passed the Graphics object from paint".
How do I pass the Graphics object?
Thanks.
Alan

The paint method has one parameter, Graphics. So you over-ride the patient() method like so, and call your method passing the Graphics object:
public void paint(Graphics g)
methodX(g);
and in methodX
public void methodX(Graphics g)
g.drawRect(100, 100, 100, 100);
This doesn't take the size from the user, but shows how to do the pass from paint(). Hope this helps

How to change font/ font color etc in a graphic object using JCombobox?

Hello
My program im writing recently is a small tiny application which can change fonts, font sizes, font colors and background color of the graphics object containing some strings. Im planning to use Jcomboboxes for all those 4 ideas in implementing those functions. Somehow it doesnt work! Any help would be grateful.
So currently what ive done so far is that: Im using two classes to implement the whole program. One class is the main class which contains the GUI with its components (Jcomboboxes etc..) and the other class is a class extending JPanel which does all the drawing. Therefore it contains a graphics object in that class which draws the string. However what i want it to do is using jcombobox which should contain alit of all fonts available/ font sizes/ colors etc. When i scroll through the lists and click the one item i want - the graphics object properties (font sizes/ color etc) should change as a result.
What ive gt so far is implemented the jcomboboxes in place. Problem is i cant get the font to change once selecting an item form it.
Another problem is that to set the color of font - i need to use it with a graphics object in the paintcomponent method. In this case i dnt want to create several diff paint.. method with different property settings (font/ size/ color)
Below is my code; perhaps you'll understand more looking at code.
public class main...
Color[] Colors = {Color.BLUE, Color.RED, Color.GREEN};
        ColorList = new JComboBox(Colors);
ColorList.addActionListener(new ActionListener() {
            public void actionPerformed(ActionEvent ev) {
                 JComboBox cb = (JComboBox)ev.getSource();
                Color colorType = (Color)cb.getSelectedItem();
                drawingBoard.setBackground(colorType);
          });;1) providing the GUI is correctly implemented with components
2) Combobox stores the colors in an array
3) ActionListener should do following job: (but cant get it right - that is where my problem is)
- once selected the item (color/ font size etc... as i would have similar methods for each) i want, it should pass the item into the drawingboard class (JPanel) and then this class should do the job.
public class DrawingBoard extends JPanel {
       private String message;
       public DrawingBoard() {
              setBackground(Color.white);
              Font font = new Font("Serif", Font.PLAIN, fontSize);
              setFont(font);
              message = "";
       public void setMessage(String m) {
            message = m;
            repaint();
       public void paintComponent(Graphics g) {
              super.paintComponent(g);
              //setBackground(Color.RED);
              Graphics2D g2 = (Graphics2D) g;
              g2.setRenderingHint
              g2.drawString(message, 50, 50);
       public void settingFont(String font) {
            //not sure how to implement this?                          //Jcombobox should pass an item to this
                               //it should match against all known fonts in system then set that font to the graphics
      private void settingFontSize(Graphics g, int f) {
                     //same probelm with above..
      public void setBackgroundColor(Color c) {
           setBackground(c);
           repaint(); // still not sure if this done corretly.
      public void setFontColor(Color c) {
                //not sure how to do this part aswell.
               //i know a method " g.setColor(c)" exist but i need to use a graphics object - and to do that i need to pass it in (then it will cause some confusion in the main class (previous code)
       My problems have been highlighted in the comments of code above.
Any help will be much appreciated thanks!!!

It is the completely correct code

Image in a Graphics object

Hi, I'm dealing with the Batik API for working with svg images, but I need to do some wmf imager representation too.
This API offers a class which is able to read WMF files, giving a "WMFRecordStore", that you can use to initialize a "WMFPainter".
Anyway, this WMFPainter class has a "paint" method which I hoped that I could use to print the wmf info in the screen but... I don't know if it can be done.
You must pass a Graphics object to the "paint" method.
If I want to add an image to a JLabel, as I'd do with an ImageIcon, do I have to get the current JLabel Graphics object? Will the image keep displayed when repainting? Is this a correct way of doing this?
thanks a lot

if you have to paint special things on a component, you have to subclass the component and override the paint (or paintComponent) method. You don't want to be getting the graphics object from a component and draw on it, it's not going to work properly.

Printing graphics object in Landscape or portrait mode

Hello,
I have a graphics 2d object (a Tree Diagram) which is inside a JScrollPane,and the JSCrollPane is on a JPanel. it's length and width is more than one page. I am using a printable object to print the object. The task I need to do is,
(1). compress the width and length of the diagram, so that if can fit into one page, else split the diagram into pages, so that each part of it can be printed on different pages(page size A4) and then later those pages can be merged accordingly.
I am not able to find, how to split the graphic object(the tree diagram into pages), shoul d I try doing it using x and y co ordinate of the graphic object.

Saving Graphics Object

Is it possible to transfer a Graphics Object to another Canvas so that I can use the painted graphics there?
I have a canvas, where some texts and boxes are painted. Now I want to start another Canvas, where the user can move a Pointer in the Graphic of the other Canvas.
So I thought I hand over the Graphics-Object to my new Canvas and overwrite my actual Graphics-Object. Now I want to paint a crosspointer and move it on the screen.
I hope anyone has understood this stupid question.
Great_T

You have to use "manual" double buffering:
private Image image = Image.creaneImage(this.getWeight(), this.getHeight());
private Graphics graphics = image.getGraphics();
Paint to graphics.
public void paint(Graphics g) {
g.drawImage(image, 0, 0, Graphics.TOP | Graphics.LEFT);
Then pass your image in the new Canvas and continue to paint to it's
Graphics object
I hope this is helpful.

Paint( ) - is passing of object correct?

Thanks (in advance) for looking at this, as always,
your input is valued & appreciated.
I did get my program to work. But i dont know if i understood the question correctly... specifically the part about "squareOfStars...this method should be called from the applet's paint method & shold be passed the Graphics object from paint". Have i performed this correctly? It seems kinda redundant to me to be passing around a "Graphics g" parameter.
//Ex6_18 Write a method squareOfStars that displays a solid square
//of stars whose side is specified in integer parameter side.
//Eg: if side = 4, display 4 rows containing 4 stars each.
//Incorporate this method into an applet that reads an integer value
//for side from the user. Note that squareOfStars should be called
//from the applet�s paint method and should be passed the Graphics
//object from paint
import java.awt.Graphics;   // import class Graphics
import javax.swing.*;       // import package javax.swing
public class Ex6_18b extends JApplet {
   double number1;       // number of stars to print, row & col
   public void init()
      String firstNumber;   // first string entered by user
      // read in first number from user
      firstNumber = JOptionPane.showInputDialog(
                   "Enter size of rectangle" );
      // convert numbers from type String to type double
      number1 = Double.parseDouble( firstNumber );
   }//end of init
   public void paint( Graphics g ){
      squareOfStars( g );
   }//end of paint
   public void squareOfStars( Graphics g ){
      int x = 25, y = 25;
      for (int row = 1; row <= number1; row++){    //for each row
                                                   //print out one line
         for( int col = 1; col <= number1; col++){
            g.drawString( "* ", x = x + 7, y );
         y = y + 7;               // move down to next line for display
         x = 25;                  //reset x, so that next line starts at col 25+7
      }//end of outter for
   }//end of squareOfStars
}//end of applet

That's because it ISN'T double buffering.Yes you're right, it isn't double buffering. But it could be, I didn't show what was inside paint.
I didn't
know about the update method - is that as effective at
killing flicker as my method? I'll try it.Well that's the standard(?) way of doing it. When you call repaint(), it actually calls update. So instead of overriding repaint, I suggest overriding update(Graphics g).
While we're on the subject, I usually use
BufferedImage for double buffering in apps, but I
couldn't make that work in applets, probably because
of VM versions. What is a good way to achieve
double buffering in applets?Use a normal Image.
Image dblBuf = createImage(width, height);
Graphics dblGfx = dblBuf.getGraphics();Then just do all the drawing to dblGfx (anywhere in the code) and in paint just draw dblBuf on screen. Eliminates flicker nicely.

Graphics object of two JFrames in a single application

Hi,
I am trying to pop up two JFrames in a Java application, which are supposed to display different things(both have Jpanels to do so). However, I think that the same Graphics object is getting passed around, because the contents from the first JFrames's Jpanel is getting superimposed on the other's! I have tried explicity to insert a 'this.getGraphics()' in all the paints and then use those Graphics objects for drawing purposes, but that has not solved the problem yet!
Any suggestions on what needs to be done?? Unfortunately, the code is too much to paste here:)
Thanks!!!

However, I think that the same Graphics object is getting passed aroundI doubt this. If you are override paint(..) or paintComponent(...) methods then you have a bug in your code. There is no need to explicitly insert a this.getGraphics(..) in your code.
Maybe you are trying to use the same panel in two frames. This is not allowed.

Trying to pass and object variable to a method

I have yet another question. I'm trying to display my output in succession using a next button. The button works and I get what I want using test results, however what I really want to do is pass it a variable instead of using a set number.
I want to be able to pass the object variables myProduct, myOfficeSupplies, and maxNumber to method actionPerformed so they can be in-turn passed to the displayResults method which is called in the actionPerformed method. Since there is no direct call to actionPerformed because it is called within one of the built in methods, I can't tell it to receive and pass those variables. Is there a way to do it without having to pass them through the built-in methods?

Trying to move a graphics object using buttons.

Hello, im fairly new to GUI's. Anyway I have 1 class which makes my main JFrame, then I have another 2 classes, one to draw a lil square graphics component (which iwanna move around) which is placed in the center of my main frame and then another class to draw a Buttonpanel with my buttons on which is placed at the bottom of my main frame.
I have then made an event handling class which implements ActionListner, I am confused at how I can get the graphics object moving, and where I need to place the updateGUI() method which the actionPerformed method calls from inside the event handling class.
I am aware you can repaint() graphics and assume this would be used, does anyone have a good example of something simular being done or could post any help or code to aid me, thanks!

Yeah.. here's an example of custom painting on a JPanel with a box. I used a mouse as it was easier for me to setup than a nice button panel on the side.
Anyways... it should make it pretty clear how to get everything setup, just add a button panel on the side. and use it to move the box instead of the mouse.

I am trying to set this map data using java code ,
     HashMap procADMap1 = new HashMap(5);
               PropertyTypeWS pType = new PropertyTypeWS();
               pType.setTypeIndex(2);
          AppdataDefImplWS appData1 = new AppdataDefImplWS();
          appData1.setName("Project");
          appData1.setType(pType);
          appData1.setMaxSize(400);
          appData1.setLOB(false);
     appData1.setDefaultValue("Project Default value");
          procADMap1.put(appData1.getName(), appData1);
          setVariableData("request","createNs","/createNs/namespaceData/appdataDef",procADMap1);
Then I am passing request object to the method which I want to invoke from bpel process.
I am able to deploy the application but when I do post message I am getting following exception,
NamespaceWithMap (createNamespace) (faulted)
[2004/09/09 18:35:54] "{http://schemas.oracle.com/bpel/extension}bindingFault" has been thrown. Less

Is there any other way to handle Map type in bpel process?
Thanks in advance,

Thanks for the quick reply.Actually the web service is already deployed on the server.What I want to do is use existing wsdl file of the deployed web service and invoke the method of the same using oracle PM.
If I remove element which uses apachesoap:Map type it just works fine also I am getting the complex object returned by the web service method.But when I try to set appDataDef which is of type apachesoap:Map(Axis conversion for java.util.Map and it uses namespace xmlns:apachesoap="http://xml.apache.org/xml-soap") I am getting the error.
Can you give me some direction to use this exising wsdl file to set map object or it is not possible.

Creating new graphics object from a existing one and sending it for print

Hello,
i have a graphics object which is big in size, I am creating a new graphics object from the existing one as given below
//map is a graphic object
Graphic g1 = (Graphic)map.create(x,y,width,height);
Graphic g2 = (Graphic)map.create(x,y,width1,height1);
Graphic g3 = (Graphic)map.create(x,y,width2,height2);
arrayList.add(g1);
arrayList.add(g2);
arrayList.add(g3);
Now I want to send the graphic object g1,g2,g3 for print in the method
public int print (Graphics g, PageFormat pf, int idx) throws PrinterException {
// Printable's method implementation
if (curPageFormat != pf) {
curPageFormat = pf;
pages = repaginate (pf);
if (idx >= 3)) {
return Printable.NO_SUCH_PAGE;
g = (Graphics) arrayList.get(idx);
return Printable.PAGE_EXISTS;
This is not working... what is wrong. can anybody suggest..
I tried standardprint.java to print a object inside a scrollpane, it is not printing the entire diagram. so I am thinking of something like this.... Please let me know what to do....
Thanks
Serj

The easy way to do this is create a copy using Windows Explorer.
Open the project and go to File > Rename.
Then you have your 2013 ready made project.

Problem with decimal data visualization in a circular graphic object type

When we are design a report using Crystal Reports 2008 we found the following problem. When we insert an object of type circle graphic selecting the option in the graphics wizard for view in the legend data both in value and percentage (u2018bothu2019 design) we cant show them in a two decimals format at the same time.
Using the option u2018number formatu2019 and indicating two decimals only affects the value but not the percentage.
Show both the value and the percentage with two decimals at same time itu2019s a necessary requirement for our report design.
Is there any way to show both the value and the percentage in a circle graphic object with two decimals at the same time?
Thanks.

hello Jose,
i am not sure what you mean by "circular graphic object type".
there's nothing in the standard cr 2008 build that has this that i've ever found that creates a circle other than inserting a box and changing the rounding on the corners. if you're using a 3rd party product or add-on you'll need to contact whoever built it.
cheers,
jamie

Best way to draw thousands of graphic objects on the screen

Hello everybody, I'm wanting to develop a game where at times thousands of graphic objects are displayed on-screen. What better way to do this in terms of performance and speed?
I have some options below. Do not know if the best way is included in these options.
1 - Each graphical object is displayed on a MovieClip or Sprite.
2 - There is a Bitmap that represents the game screen. All graphical objects that are displayed on screen have your images stored in BitmapData. Then the Bitmap that represents the game screen copies for themselves the BitmapData of graphical objects to be screened, using for this bitmapData.copyPixels (...) or BitmapData.draw (...). The Bitmap that represents the screen is added to the stage via addChild (...).
3 - The graphical objects that are displayed on screen will have their images drawn directly on stage or in a MovieClip/Sprite added to this stage by addChild (...). These objects are drawn using the methods of the Graphics class, as beginBitmapFill and beginFill.
Recalling that the best way probably is not one of these 3 above.
I really need this information to proceed with the creation of my game.
Please do not be bothered with my English because I'm using Google translator.
Thank you in advance any help.

Thanks for the information kglad. =)
Yes, my game will have many objects similar in appearance.
Some other objects will use the same image stored, just in time to render these objects is that some effects (such as changing the colors) will be applied in different ways. But the picture for them all is the same.
Using the second option, ie, BitmapDatas, which of these two methods would be more efficient? copyPixels or draw?
Thank you in advance any help. =D

How to use a Graphics Object in a JSP?

Hello, I do not know if this is a good or a silly question. Can anyone tell me if we can use a Graphics object in a JSP. For example to draw a line or other graphics, i am planning to use the JSP. Any help is much appreciated.
Regards,
Navin Pathuru.

Hi Rob or Jennifer, could you pour some light here.
I have not done a lot of research for this, but what i want to do is below the polygon i would like to display another image object like a chart... is it possible? If so how to do it? Any help is much appreciated.
here is the code:
<%
// Create image
int width=200, height=200;
BufferedImage image = new BufferedImage(width,
height, BufferedImage.TYPE_INT_RGB);
// Get drawing context
Graphics g = image.getGraphics();
// Fill background
g.setColor(Color.white);
g.fillRect(0, 0, width, height);
// Create random polygon
Polygon poly = new Polygon();
Random random = new Random();
for (int i=0; i < 5; i++) {
poly.addPoint(random.nextInt(width),
random.nextInt(height));
// Fill polygon
g.setColor(Color.cyan);
g.fillPolygon(poly);
// Dispose context
g.dispose();
// Send back image
ServletOutputStream sos = response.getOutputStream();
JPEGImageEncoder encoder =
JPEGCodec.createJPEGEncoder(sos);
encoder.encode(image);
%>
