How can i call the public void paint(Graphics g) method on click of button?

Hello,
I have done this before i know its got to do something with the repaint() method but can someone show me with and example and call the paint method using AWT in a frame not in an applet....
Thank you very much.

Thank You very Much.... You have cleared all my doubts.
But my main objective is to display an image in an AWT Frame !!
here is the code that i have been trying..
import java.awt.*;
import java.awt.event.*;
public class check6 extends Panel
     Frame f;
     Image i;
     public check6()
          f = new Frame("Heading");
          f.addWindowListener(new WindowAdapter(){
               public void windowClosing(WindowEvent e){
                    System.exit(0);
          final Button b1 = new Button("Submit");
          b1.addActionListener(new ActionListener() {
               public void actionPerformed(ActionEvent e){
                    repaint();
          i = getImage(getCodeBase(), "titanic.jpg");
          add(b1);
          setLayout(new FlowLayout(FlowLayout.LEFT));
          f.add(this);
          f.setSize(500,500);
          f.setVisible(true);
     public void paint(Graphics g)
          g.drawImage(i,10,10,this);
     public static void main(String args[])
          new check6();
}

  • How can we call the method of used controller?

    Please help me to resolve this....
    Regards,
    Ravi

    You can not directly call view's event handler from other component.
    create a method in component controller of the second component and in the button click call the component controller method. ( also make the method as interface so that you can call it from other components )
    Now, you can call the interfacecontroller's method
    DATA: l_ref_INTERFACECONTROLLER TYPE REF TO ZIWCI__VSTX_REBATE_REQ_WD .
      l_ref_INTERFACECONTROLLER =   wd_This->wd_CpIfc_<comp usage name>( ).
      l_ref_INTERFACECONTROLLER->Save_Rr(
        STATUS = '01'                       " Zvstxrrstatus
    save_rr is the method of second component controller

  • How can I call the jFreeChart to plot graph and get the result in Servlet?

    I want to use jFreeChart to plot time series graph, and then output the result in Servlet. How can I call the jFreeChart to plot graph and get back the result? Any source code for example? Thanks a lot!!

    Dave,
    ServletDemo1 and others were not in the distribution that I got (jfreechart-0.9.4). I found them under the premium demos somewhere in com/refinery/chart/demo/premium, but could not compile. They're complaining, among other things, about missing classes/packages com.refinery.date.SerialDate and com.refinery.ui. Am I using a wrong version of jfreechart?
    Thanks,
    -Alla
    There is a very simple servlet demo in the JFreeChart
    distribution:
    src/com/jrefinery/chart/demo/ServletDemo1.java
    This simply sends back an image to the browser.
    A second demo, which embeds the chart in an HTML page
    is:
    src/com/jrefinery/chart/demo/ServletDemo2.java
    src/com/jrefinery/chart/demo/ServletDemo2ChartGenerator
    java
    ...includes a time series chart as one of three
    options.

  • How can I call the create method in BO from Application Service

    Hello!
    When I create a Business Object, CAF generates some methods automatically.
    How can I call the create method in the BO from Application Service logic?
    When i call the method then the entityManager and the sessionContext is NULL.
    How can I initialize this?
    Can anybody help me?
    Thanks, Thomas

    If you are using CE 7.11...
    1) In the Application Services, add the BO as dependant object in dependencies tab.
    2) In the implemention, add the following codes to call create method of the BO:
    this.get<BO>.createMethod();

  • How can I Call the MainVI from its SubVI, and this happen recursively?

    Hi All,
    How can I Call the MainVI from its SubVI, and this happen recursively?
    Actually, LAbView 7.1 doesn't support recurssion?
    Plz help me out!

    Dear GerdW,
    Thanks a lot 2 all of u guys,for all the brilliant responses.
    Actually, my basic aim is to call the Main VI, containing a SubVI.....
    Now, I want to call my main VI from this SubVI...recursively!!!!!..but whenever I tried to put the MainVI in this SubVI..an error message pops out saying recursive calling is not possible.
    I also tried using "Call by reference" but tht also didn't worked...an d error is somewat like...VI is invalid..or type matching..or state matching error.
    Here, Im attaching the snapshot of the MainVI... Im calling the SUBvi from it... It is running GOOD n FINE...
    But prob arrives when I call the Main from the SUBvi, which looks like same as MainVI(with little differences).
    I hope, Im clear in my words n not being ambigous.
    Plz, correct me where ever  im wrong.
    Thank You.

  • How can I call a public function in one component from another component?

    I have two components: Form and Confirmation.  Form is a Canvas and Confirmation is a TitleWindow.
    Form contains several controls and a submit button.  Confirmation contains an OK button.  When the user clicks the submit button, the Confirmation appears over the Form (Form is blurred).  When the user clicks the OK button on the Confirmation, I want to run a function on Form to set some default values in the controls.
    How can I address the function in the Form component from the Confirmation component so I can fire the function?

  • How can integrate/call the Oracle Forms in ADF pages or task flow.

    Hi ,
    I Have requirement to integrate the ADF and EBS.
    I have done the ADF pages calling in ESB.
    Right now i am struck up to call the OAF froms in ADF page/taskflow.
    it's high appriciate if any one provide me the any info or how to do this requriment.
    Thanks,
    Madhava.

    Hi,
    Forms integration can happen using af:inlineFrame or by a redirect to a Forms web URL. In the latter case navigation should be from an unbounded task flow ensuring the return address required to resume the ADF application is provided. See: https://blogs.oracle.com/jdevotnharvest/entry/how_to_efficiently_redirect_an for how to construct the return URL
