The program below compiles and functions correctly for the most part. It is supposed to be a simple GUI Text Editor with Edit and Format functions. The content pane is supposed to be a scroll pane, however no matter how much I type into the editor, the scroll bar does not appear. Also, the none of the functions under the "Edit" menu work.
I have tried to add a scroll bar line 28 - 31 and can't figure out why its not working. Its not even showing the scroll bar!
public class TheFrame extends JFrame { private static ThePanel canvas; private String deckImagesToUse; /** * The constructor creates a Frame ready to display the cards */ public TheFrame(String cardImgFile) {
I am developing an application to share my client screen with server, it is working well on swing. But i want to develop as web application, i am trying to using applet. But i am facing the fallowing problem..,
1) The Applet screen also open and project also running well on server mechine. But unable to see the client screen on the server.
2) The problem may be to display the JDesktopPane or JInternalFrame.
My working Server Code extends withe JFrame..Java Code:
1. The human user of my application asks it to fire up a scanner which scans a paper document. The document is a filled in form. 2. The application then displays the scanned image to the human user.The image is displayed in a JScrollPane since it may be larger than the scroll pane. 3. The human user needs to locate a certain item in the form, for example a social security number, and enter it into a field in a data entry screen.Note that the image and the field appear on the same screen.
Of-course the social security number always appears in the same location in the image. Also the image needs to be the appropriate magnification and resolution to allow the human user to easily read and understand the item he is searching for in the image.
What is the best way to present the scanned image to the user such that he immediately sees the item he requires and can enter it into the data entry field.
I'm having serious issues right now with a JTable inside a JScrollPane.i have some methods that returns different indexes (rows) that i select programatically in a JTable and the problem is that sometimes it goes beyond of what i can see, like, the row gets selected but the scrollbar won't follow up.
i've searched up in google and saw several different methods but those were extremely complex and for stuff i don't need.the simplest solution i found is this:
but it just doesn't do anything.My table (tInfo) has only two columns so no horizontal bars, just vertical. What can i do to align the scrollbar with the currently selected row in my table? :C
Found a solution using scrollPane.getVerticalScrollBar().setValue();in another thread, i didn't even notice there were like 3 more threads about the same, just different kind of code used in each.
I have my below Swing GUI code in which I want to read and display some contents present in text file say (test.txt) which is located in my local disk (C: est.txt). My pane tab 2 is divided into two halves horizontally. How can I read and write the test.txt file contents under the tab tab2 in the first half of the pane(where currently it is 2 written)?
Sample test.txt present in my local hard disk location username:test1 Password:test1 DataBasename: testDB
CODE FOR TABBED PANE
import javax.swing.*; import java.awt.*; public class SplitPaneExp { public static void main(String[] args){ Runnable r = new Runnable() { public void run() { JFrame frame = new JFrame("WELCOME");
I'm dealing with, change the content pane color of jFilechooser. Color has been changed but the problem is when I open the subdirectory leads errors; Note : It also trigger error when I set default directory; like chooser.setCurrentDirectory(file);
The following error is the result:
Exception in thread "AWT-EventQueue-1" java.lang.NullPointerException at javax.swing.plaf.metal.MetalFileChooserUI$IndentIcon.getIconWidth(MetalFileChooserUI.java:912) at javax.swing.SwingUtilities.layoutCompoundLabelImpl(SwingUtilities.java:961) at javax.swing.SwingUtilities.layoutCompoundLabel(SwingUtilities.java:888) at javax.swing.plaf.basic.BasicLabelUI.layoutCL(BasicLabelUI.java:94) at javax.swing.plaf.basic.BasicLabelUI.getPreferredSize(BasicLabelUI.java:239)
Is there a way to simply slap a rectangle into a JPanel (make it appear) with out creating an inner Class or helper Method, all within "Main"? And if not, why?
Making a JFrame is easy.
Adding a JPanel is a snap.
import java.awt.Color; import javax.swing.JFrame; import javax.swing.JPanel; public class TheJFrame { public static void main(String[] args) { // TODO Auto-generated method stub
I have a Jframe and i want to add inside 4 different jpanel.This is easy.
what is difficult is how can i change them dynamically with 4 other new jpanels and 4 other new jpanels?
I have try with BorderLayout but not working.
It's a wizard like but not the same.
I have a jpanel with jbuttons jpanel with a jtable jpanel with textarea and jpanel with jlabels. All this have to change with other 4 jpanels, where to look?
All I need to do is show in just one JFrame the two combined JFrames. One JFrame namely leftPanel will appear to the left or west and the other namely rightPanel to the right or east using BorderLayout. I already did creating them first as JPanels or as internal classes and subsetted them in one JFrame but that didn't work because it looked messy. And now I've created them as two separate JFrames, compiled separately, and tried to subset them as one in the JFrame. I didn't add any functionality to this program because all I intend to do is to show those two JFrames together in one JFrame. Here's the code:
import javax.swing.*; import java.awt.*; import java.awt.event.*; public class dirtyIceCream extends JFrame { leftPanel westPanel; rightPanel eastPanel; public dirtyIceCream()

What am I missing or did I code anything wrong here? Or should I use NetBeans IDE for anything as complicated as this?
I am rather new to Swing, and I am building a game right now in which I need to display a pop-up window as a reminder for what commands exist within the game. I created a class extending JFrame for this and added all the information I need. However, for some reason, no matter how many different ways I try to set the size of this window (setSize(w, h), pack(), using a different layout, adding the compnents to a JPanel first and setting the preffered size of that, then adding the JPanel to the JFrame), it doesn't work. Instead of a window of my requested size, I get a tiny, maybe 100 x 100 pixel window that needs to be resized in order for its contents to be visible.
package GUI; import javax.swing.JFrame; import javax.swing.JPanel; import java.awt.Graphics; import java.awt.Color; public class gui5 { int x=0; int y=0; public static void main(String... x) {

but just a Jframe is appearing no Jpanel no green color circle?What is wrong with code
Following is the code on the click of a button, id like to know how do i close the current jframe on which the jButton4 is currently placed. I know how to send it to the next Jframe i.e JobCard. But need to close the current one. I tried using this.setVisible(true); But it does not work.
private void jButton4ActionPerformed(java.awt.event.ActionEvent evt) { // TODO add your handling code here: this.setVisible(false); JobCard jobCard = new JobCard(); jobCard.setVisible(true); }
I need to put a Web Page in my JFrame application , I got a lot codes on the internet and could implement without problems , but the problem is that this code has an ugly page as hell, with colored all wrong and with a very poor quality , one of code I used was this :
* import javax.swing . ;
{ public class SwingWebPage public static void main ( String args [ ] ) throws Exception { JEditorPane website = new JEditorPane ( " http://www.google.com/ " ) ; website.setEditable ( false) ;
[code]...
If you test , you'll see that the page is displayed in the JFrame is horrible.
I am try to do an application based in multiples JFrames, each one with its particular responsibilities, and use one JPanel as a menu with buttons that connect one JFrame to another, But this menu is instantiated at run in view (layout made by netbeans) the Main Jframe appears with its internal JPanel, but the instantiated JPanel does not appear or does not show it's buttons. (notice only run method in the second class):
JPanel Menu that will be used in all alone JFrames of application:
public class MenuSuperior extends javax.swing.JPanel { public MenuSuperior() { initComponents(); } private void initComponents() {
I want my jrame should not be resized when clicking on maximize button of window.and for this i have put setResizable(false)in the constructor of class which extends Jframe.
I didn't know about right method for correct close operation for JFrame component or kill the object. I found out few, which of them you are using usually???
This is right from a book I'm reading but it doesn't work. The problem is to write an application that lets you determine the integer value returned by the InputEvent method getModifiers() when you click your left, right, or middle mouse button on a JFrame.
This is the code copied directly from the book. What is missing:
import java.awt.event.InputEvent; import java.awt.event.MouseAdapter; import java.awt.event.MouseEvent; import java.awt.event.MouseListener; import javax.swing.JFrame; public class JLeftOrRight {
I trying to replace original (and empty) JPanel in JFrame with my own made one, components does no appear right, when I pass the mouse first button appears:
