jframe

hi guys..... am a newbie in java i found difficulties when am trying to put picture or an ascii art in jframe maybe u guys can give me some hints....(based on my code),here i submit a part of my code in jframe section:.. import java awt.*; import javax swing.*;import java awt. Color;import javax swing. JOptionPane;import java util. Date;class MyFrame extends JFrame { public void paint ( Graphics g ) {this setBackground(Color. BLACK);g setColor(Color. RED);g setFont(new Font("Serif". Font. BOLD. 18));g drawString("WELCOME". 200. 50);g setFont(new Font("Serif". Font. BOLD. 14));g drawString("\n". 10. 70 );g drawString("Date = " + new Date(). 10. 140); }} You should never (well almost never) override the paint() method of a JFrame. You should override the paintComponent(Graphics g) method of another component (say a JPanel) and set the component as the 'content pane' of the JFrame thanks for the reply sabre150.. did you mean i must create a new object inside that frame (like JPanel) instead of painting the frame itself? but how if you want to put picture or even painting the object itself? but how if you want to put picture or even painting the object itself? I don't really understand. Do as you have in your current code but do it in the paintComponet method of a JPanel and set the JPanel as the 'content pane' of your JFrame. I don't know how else to say it! In the future. Swing related questions should be posted in the Swing forum. Read the Swing tutorial on "Custom Painting" for a step by step example:http://java sun com/docs/books/tutorial/uiswing/painting/index html

So I can paint directly on a JFrame and I can create on a class that extends adorn and put the Panel on a JFrame. But if I try to Repaint the Panel it won't show on the JFrame. Do I have to do anything to the JFrame to show the changes to the objects inside as well? I'm not sure if you've done this but don't change the paint method when using Swing components use paintComponent instead. By default the JFrame will paint its children. Just remember whenever overriding any of the paintComponent methods to call super paintComponent(g) first. yert527 wrote:Never mind please excuse the idoit who forgot to add the action listener. That was going to be my next suggestion honest. :)

We've had some interesting contributions to the this past week. One of them comes from Joseph Cotton: . This Tips & Tricks entry shows you how to make communication possible between two JFrame panels. For example pushing the button on panel B and undergo a message placed in the text box in panel A. (and endorse versa). Be sure to analyse this out. I'm certain that you'll like what you see. When do we get to see YOUR contribution? Posted by branajam ( Oct 26 2007. 07:04:30 PM CEST ) I think a better way to do this would be to have a listener on A that can listen to events dispatched by B. That way if you undergo "two" B frames change state you are not stepping on your frame's references. Sending a message on the EDT in this case is probably not a big deal although using an EventBus -- see eventbus dev java net would be more effective.

Getting above errror when running the code below how do I install the Jframe so the schedule can see it. Looks like JRE and JDK does not undergo it. import javax swing.*; import java awt.*; import java awt event.*;public class SimpleGui1{ public static void main(String []args){ JFrame close in = new JFrame(); JButton button = new JButton("click me"); frame setDefaultCloseOperation(JFrame. move_ON_CLOSE); frame getContentPane90 add(button); frame setSize(300,300); frame setVisible(true); } This is the error I'm getting:C:\Documents and Settings\mommy\My Documents\Java Projects\jframe\SimpleGui1 java:17: cannot sight symbolsymbol : variable getContentPane90location: categorise javax swing. JFrame frame getContentPane90 add(button); ^1 errorTool completed with exit label 1 You're welcome. In future though look where it's giving you an error and try actually looking at the lie that the error is occurring on. I think that should of been really easy to sight since it be'd you intended to write () in the first place but just didn't have your shift key pressed.
