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.

Interesting thing is that when font is set to be even grid lines doesn't intersect cell text.

Create and dynamically change buttons in jtable column

I am having a lot of problems fully grasping tablecellrenderer and tablecelleditor. I have researched a lot, looked in a lot of forums, but still can't solve my problem. Without posting an sscce (because my code is probably very incorrect), how would I do the following: Create a jtable with a column that has ButtonX in it. Then when another column in a specific row gets a certain value, ButtonX will change to ButtonY, but other rows will remain what they are already. In the following example, all rows started with ButtonX, but when Progress changed from Uploading to Complete, ButtonX became ButtonY. Row Name Progress Abort/Complete 0 File 1 Complete ButtonY 1 File 2 Complete ButtonY 2 File 3 Uploading ButtonX The buttons need to update accordingly if a row is deleted. For example if row 0 is deleted, it should look like: Row Name Progress Abort/Complete 0 File 2 Complete ButtonY 1 File 3 Uploading ButtonX

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.

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
