JSlider update another JSlider problems

Hi , I am taking Java classes at a college level. I am playing around with JSliders and an addChangeListener. The gist of my code is I have two sliders, one is MPH the other is KPH. When one slider is slid, the two fields update and the other slider follows. if you move the other slider, the same happes. My problems seems that when the addChangeListener updates the other slider, it calls the same addChangeListener and then they both stick at 0. I am using an if statement to run seperate commands depending on which slider calls the addChangeListener. in this code if I uncomment the statements to update the other slider in the addChangeListener then it doesnt work, with them commented, the other slider does not update. Im stuck.

Program.launch of Mac OSX TextEdit can cause problems

My SWT application has been used in both Windows XP/Vista/7 and Mac OSX for several years. Recently, in certain org.eclipse.jface.action.Action classes I've added the option to open *.txt files (these are newly created operational reports). The files are opened by calling org.eclipse.swt.program.Program.launch(fileName), where fileName is the full path name for a particular *.txt file. In Windows, there are no issues with this scenario. In Mac OSX, if the user first launches the text-related program (e.g., TextEdit) before launching my SWT application, there are no issues with this scenario. In Mac OSX, if the user first exits the text-related program (e.g., TextEdit) launched by my SWT application before attempting to exit my SWT application (via menu's "Quit", etc.), there are no issues with this scenario. In Mac OSX, if the users does not exit the text-related program (e.g., TextEdit) launched by my SWT application before attempting to exit my SWT application, my SWT application's window closes... but the icon is left behind in the Dock (a.k.a., system taskbar) and my SWT application has not actually exited. I have to manually terminate my SWT application via Force Quit. Any suggestions about this problem would be welcome.

changing headers on JTable caused other problems

Hi Guys, I'm working with a JTable which sets up certain columns with cell renderers and editors. My application allows the user to change the interface to a different language, so JMenuItems, buttons, etc. change their text and I've set it up so that the header on the JTable changes as well. Two lines of code make that happen: private void changeTableHeaders() { ((JLTableModel)table.getModel()).setHeaders(this.getHeaders()); ((JLTableModel)table.getModel()).fireTableStructureChanged(); }

Simple text printing with pagebreaks

I have a report displayed in a GUI application as a simple text within JTextComponent. My goal is to print it but with page breaks at certain points. I have inserted \f at those places, however when I print page breaks are ignored and I get a weird character printed in those places where \f was and the rest of the text is just printed out without page breaks. One thing I v noticed is that if I output the report to a file and open it with MS Word page breaks are recognised and report is displayed correctly. However, if I try to open it with notepad page breaks are not recognised. I have tried converting the text to RTF but the \f character was still ignored. I would really appreciate if anyone shares their experience with something similar and how did you solve it cheers

I tried an example from another site and that one works perfectly (http://java.sun.com/docs/books/tutorial/uiswing/misc/printtable.html). Does anyone know what's going wrong Is my table too large for the paper and do I need to resize it, and if so how

JTable printing problem

I have sample of JTable with data that i would like to be right aligned, also orange background color cell renderer is applied, and font is set to be Tahoma BoldItalic with font size of 13. Problems that arise are, grid lines are over cell text, and also applied background color looks strange when PDF printer is used and document is zoomed.

Problem in printing JTable values

Dear Friends, I have to print the JTable values (on paper using print dialogue box). I'm using jtableObj.print to print the table values. But jtableObj.print takes more time to print the table values because it prints the values as a image(approximately 5 mins to print 10 pages). My code is , boolean complete = tableObj.print(mode, header, footer, showPrintDialog, null, interactive, null);

JTabbedPane problems - not loading correctly

I think i don't have something set correctly, but when I try to use JTabbedPanes it never loads correctly. If I have 3 tabs, tab 3 loads up first and I have to select all the tabs at least once before it works correctly. Here is an example of what i mean. I used this program written by Dave Marshall to see where i was messing up, but i get the same problem when i run it.m Any help would be great! -------------------------- import java.awt.*; import javax.swing.*; class TabbedPaneExample extends JFrame { privateJTabbedPane tabbedPane; privateJPanelpanel1; privateJPanelpanel2; privateJPanelpanel3; public TabbedPaneExample() { setTitle( "Tabbed Pane Application" ); setSize( 300, 200 ); setBackground( Color.gray ); JPanel topPanel = new JPanel(); topPanel.setLayout( new BorderLayout() ); getContentPane().add( topPanel ); // Create the tab pages createPage1(); createPage2(); createPage3(); // Create a tabbed pane tabbedPane = new JTabbedPane(); tabbedPane.addTab( "Page 1", panel1 ); tabbedPane.addTab( "Page 2", panel2 ); tabbedPane.addTab( "Page 3", panel3 ); topPanel.add( tabbedPane, BorderLayout.CENTER ); } public void createPage1() { panel1 = new JPanel(); panel1.setLayout( null ); JLabel label1 = new JLabel( "Username:" ); label1.setBounds( 10, 15, 150, 20 ); panel1.add( label1 ); JTextField field = new JTextField(); field.setBounds( 10, 35, 150, 20 ); panel1.add( field ); JLabel label2 = new JLabel( "Password:" ); label2.setBounds( 10, 60, 150, 20 ); panel1.add( label2 ); JPasswordField fieldPass = new JPasswordField(); fieldPass.setBounds( 10, 80, 150, 20 ); panel1.add( fieldPass ); } public void createPage2() { panel2 = new JPanel(); panel2.setLayout( new BorderLayout() ); panel2.add( new JButton( "North" ), BorderLayout.NORTH ); panel2.add( new JButton( "South" ), BorderLayout.SOUTH ); panel2.add( new JButton( "East" ), BorderLayout.EAST ); panel2.add( new JButton( "West" ), BorderLayout.WEST ); panel2.add( new JButton( "Center" ), BorderLayout.CENTER ); } public void createPage3() { panel3 = new JPanel(); panel3.setLayout( new GridLayout( 3, 2 ) ); panel3.add( new JLabel( "Field 1:" ) ); panel3.add( new TextArea() ); panel3.add( new JLabel( "Field 2:" ) ); panel3.add( new TextArea() ); panel3.add( new JLabel( "Field 3:" ) ); panel3.add( new TextArea() ); } // Main method to get things started public static void main( String args[] ) { // Create an instance of the test application TabbedPaneExample mainFrame= new TabbedPaneExample(); mainFrame.setVisible( true ); } }

JScrollPane and paint method problems

Currently, I'm trying to make a program to handle double elimination brackets for a team tournament. One of my classes involves overwritting the paint method in order to display the brackets. The code is as follows: public void paint(Graphics g) { super.paint(g); drawPortion(bracket.getBracket(), getWidth()/2, 10, bracket.getDegree(), g); } private void drawPortion(BinaryTreeNode b, int x, int y, int degree, Graphics g) { drawPortionRecursive(bracket.getBracket(), getWidth()/2, 10, degree, g, 1); }

JTable printing . . .

I have customized the column widths of a JTable to display properly on screen. But this size of the JTable doesn't looks good on the print when i set the JTable.PrintMode.FIT_WIDTH option, which produces small table on paper. But when the column widths are reduced on screen it looks very good on paper, and losses its look on screen.So, i want to make the table to fit width both on the screen and paper also. How to achieve this Thank you.
