printing JTables - concatenating? what about the panels?


I am printing a JTable in this manner:

StringBuffer sb = new StringBuffer(); PrintRequestAttributeSet attribs = new HashPrintRequestAttributeSet(); attribs.add(new Copies(1)); attribs.add(OrientationRequested.PORTRAIT); int xx = 1; //left and right margin int yy = 1; //top and bottom margin. Note that bottom margin cannot be less than 15 mm int ww = 845; //Width int hh = 599; //Height int units = MediaPrintableArea.MM; attribs.add(new MediaPrintableArea(xx, yy, ww, hh, units)); String title = "My Table"; sb.append(title); MessageFormat footer = new MessageFormat("Page {0}"); getPayrollHeadcountList().getTable().setPreferredSize(new Dimension(500, 500)); getPayrollHeadcountTotalList().getTable().setPreferredSize(new Dimension(500, 100)); try { getPayrollHeadcountList().getTable().print(PrintMode.FIT_WIDTH, header, footer, true, attribs, false); //getPayrollHeadcountTotalList().getTable().print(PrintMode.FIT_WIDTH, header, footer, true, attribs, false); } catch (PrinterException pe) { Debug.trace(pe); }

Question about drop down lists from JComboBox within an applet

When I click on the down arrow of a standard JComboBox in an applet and the list of strings are displayed, if I then drag the browser window, the drop down list stays in the same place instead of either being closed or moving with the browser window. I started noticing this when I started using Java 7, but I think this also occurs with Java 6 and 5. When run within the applet viewer in Eclipse, moving the applet window there closes the drop-down during the process of moving the window. Anybody else noticing this If so are any suggestions for a possible solution. Ideally I'd want the list to move with the browser window without the drop-down closing. My example code that demonstrates the problem is as follows: import javax.swing.JApplet; import javax.swing.JComboBox; public class ComboApplet extends JApplet { public void init () { String [] testStrings = new String [] {"This", "is", "a", "test"}; JComboBox comboBox = new JComboBox(testStrings); add(comboBox); } }

Question about programming style

When creating a gui application or an applet, is there a standard about the best way to set up the code For example, is it better to layout the code like this public void init() { setLayout(null); output = new JTextField("This is a textfield", 100); output.setBounds(0, 0, 100, 50); add(output); one = new JButton("1"); one.setBounds(5, 40, 50, 50); add(one); two = new JButton("2"); two.setBounds(65, 40, 50, 50); add(two); }

Question about Color and BufferedImage

Hi , I'm trying to learn more about java computer graphics, and in my study I encountered following problem. Probably there is a simple solution to this, but I'm baffled. Here's the question, why the integers that represent color are not the same Also I noticed that when I change value 255 => 254 the integer of the color object gets recalculated but the one in the bufferedImage doesn't, why is that public static void main(String[] args) { Color c = new Color(255, 110, 75, 100); BufferedImage image = new BufferedImage(100, 100, BufferedImage.TYPE_INT_ARGB); Graphics g = image.getGraphics(); g.setColor(c); g.fillRect(0, 0, 100, 100); System.out.println(c.getRGB()); System.out.println(image.getRGB(40, 40)); } Console: 1694461515 1694461514

overlapping problem of jpanels

As i got reply from Wendy Gibbons in JDBC section's topic which i created worry about other considerations when you have the simplest version working. Here i try simplest version as per my thought. I make simple swing program (Just swing no jdbc or hibernate & db), Name simpleExample.java Contains 1 JFrame, Array of jpanels.(only 3 jpanels i create by array). Major code is here., but i modified it as i try in 2-3 days after last post in that question. If you want to see how it developed, 1. 3 questions regarding JPanel. Creation of problem:- When program runs 3 panels we can see, 0,1,2. If we drag & drop panel 0 on panel 2, it will locate beside it because code goes to check_overlap_panel(); & run for loop & check if condition & set as below. simpledm.comp_panel.setLocation(simpledm.comp_panel.getX()+25, simpledm.comp_panel.getY()+25); but when we drag & drop panel 1 on panel 2,it will do same for checking ovelaping against panel 2, & setlocation as per above quote,but it forget already that location occupy by panel 0. Problem panel 1 not try to cross check overlap against panel 0. If i increase myindex = any number, then it should be try to setlocation of panel as avoid overlap against another panel. I try my best & then post question...I also try sscce for code What i do:- Here i try to create 13 boolean flags to check many if-else conditions & for easiness i create 5 functions Conditions like 1. In check_resolutionboundries() function i check panel should not move beyond systems resolution, so if program run on any monitor which has any resolution, then it will run without trouble. This function i called in mousedragged event. 2. When program runs all integers are 0 so 1st condition is check integer against 0 in function check_int_zero(). 3. When function check_int_zero() calls in chek_flags(), to check probability of flags true & false. 4. check_overlap_panel() function contain code for checking panels overlap or not. private void check_overlap_panel() { for (Counter= 0; Counter < panels.length; Counter++) { if (simpledm.comp_panel.getBounds().intersects(simpleExample.panels[Counter].getBounds())) { if (Integer.parseInt(simpledm.comp_panel.getName()) != Integer.parseInt(panels[Counter].getName())) { Flag_over= false; }else { Flag_over = true; }}}}

gridlayout not working with custom jpanel and jscrollpane; my jpanels get cut off

I'm trying to add my own implementation of jpanel to another jpanel, in a scrollpane, so that as it adds more it will make a list of them down the screen. Unfortunately I can't seem to put space between my jpanels; when I set the second two gridlayout parameters, parts of them get cut off (so that they appear shorter vertically). Any idea why this is happening or how to get around it (called from a method in a jframe class) miniPanel = new JPanel(); miniPanel.setLayout(new java.awt.GridLayout(100, 4,0,60)); for(int i=0;i

Doubt about layouts.. (its simple I think)

My doubt is simple, I dont want to use AbsoluteLayout. So, I putted a Panel inside a frame on the West position using BordeLayout (default). Then I set the frame layout to BoxLayout (YAXIS). So I putted a JLabel and a JTextBox. I wanted it: Nome: [___________________________________] But the JTextBox extended until the border of the panel. How do I fix it

Question about GUI (with NetBeans IDE)

. I want to ask about my vision for the GUI. I'm using NetBeans IDE to make it. My idea is something like this, we have a few JPanels with JLabels, and JButtons. First JPanel it's a menu and it is only visible JPanel at the application starts. When we click on the one of the buttons (let's say "Information") we change Menu JPanel Visibility to false, and the JPanel which include the "Information" is now Visible. The JPanel "Information" also has got JLabels and JButtons, and one of JButtons is a "Main Menu" which (when clicked) sets the Menu JPanel visibility as true, and set Information JPanel visibility as false. My second idea (which is just stupid ;>) is to remove all components on JButton click, and create new components. So in Menu JPanel we got JButton information. When we click it, we remove all components that are in Menu JPanel, and we create new components, that are needed in Information JPanel. I think that both ideas are terrible, but I have no other idea how to make it. I was thinking about web app, but I don't have such knowledge to create it.

Question about "Java Icons"

I am creating an application, in this application, I need to use Icons like "copy", "paste", "cut" etc. Rather than using images of my own as Icons, I know there are some "Built In Icons' in Java. Anyway, According to my requirement, there should be at least two type of the same icon, for an example, "Copy Icon NORMAL" and "Copy icon MouseHover". Is there is any kind of FREE package which provide these Icons Apart from that, this is the first time I am gonna use these BUILT IN ICONS, so please tell me how to use these too.

Java code printing junk characters in PDF

I have a JAVA code that reads a PDF file from remote server. It then merges it with an existing PDF file and print the resultant. However, sometimes I observe that the PDF printed contains gibbersih data. It doesn't happen always. Is it some issue with the fonts used in PDF Or some inherent issue of Java, while printing PDF files. I use a print job object to print PDF file. Logic for printing the PDF file is as following private boolean printDocument(String fileName){ System.out.println("printComplianceDocument : Begin"); boolean result = false; PDDocument document = null; PDPage page = new PDPage(); try { document = PDDocument.load(fileName); PrinterJob pjob = PrinterJob.getPrinterJob(); PrintRequestAttributeSet attr_set = new HashPrintRequestAttributeSet(); attr_set.add(Sides.DUPLEX); PrintService[] services = PrintServiceLookup.lookupPrintServices(null, attr_set); for(PrintService service : services){ if (service.getName().equalsIgnoreCase(SystemProp.getInstance().getWorkStation().getDfltRptPrinter().getAddress().trim())){ System.out.println("Printing Document to printer: " + service.getName()); pjob.setPrintService(service); pjob.setPageable(document); pjob.print(attr_set); result = true; break; } } //Try printing to Default Printer if appropriate Print Service is not found if(!result){ PrintService defaultPrintService = PrintServiceLookup.lookupDefaultPrintService(); System.out.println("Printing Document to Default Printer: " + defaultPrintService.getName()); pjob.setPrintService(defaultPrintService); pjob.setPageable(document); pjob.print(attr_set); result = true; } } catch (IOException e) { // Exception } catch (PrinterException e) { // Exception } System.out.println("printDocument : End"); return result; } Please share your ideas and suggest solutions if you could.
