tablerowsorter

问题 So I have successfully implemented a search feature into my tiny program but when I click the button to sort, it works fine but the images don't display. This is the code that I added for the sorter which works fine but the images for each row don't show up. When I take out this code, the images show up but the sorting doesn't work. Is there away that I can make the images show when sorting? // Sorter Code. Images show up when this code gets taken out. table = new JTable(model); final

问题 I have the following method: private void passStingR(StringBuilder retVal) throws BadLocationException { int scrollPositionR = scrollR.getVerticalScrollBar().getValue();//get value of scroll position stores in javas memory windowR.remove(scrollR); tableR.getModel(); modelR.setRowCount(0); Document docR = null; try { docR = loadXMLFromString(retVal.toString());//pull in the XML data into a new doc } catch (Exception ex) { Logger.getLogger(remit.class.getName()).log(Level.SEVERE, null, ex); }

问题 I am querying a MySQL database via Java, pulling data out of the result set and placing it in a DefaultTableModel, which gets put in a JTable, then into a JScrollPane to get displayed. In the JTable, I enable sorting in the table via table.setAutoCreateRowSorter(true); However, if the cells in the row I want to sort are not of class String, then I get a java.lang.ClassCastException. The data in my table has the following classes: java.sql.Date java.sql.Time java.lang.Double java.lang.Boolean

问题 I am developing a custom search component. When clicked on the button(search image icon) inside the text field, a table is displayed. The code is in very nascent stage so lots of things is not there. As of now, I am stuck because I am not able to navigate the table with the arrow keys. Neither am I able to move to the next text field with "tab" key, once I select a row in the table. The objective of the component is to select a row from the table and then with the help of the supporting

问题 After adding a TableRowSorter to a table and its corresponding model any corresponding adds specifically at firetabletablerowsinserted cause exceptions. It is clear from testing that the GetRowCount() is returning a value past the models range. However it does not make sense to me how to continue to add values to the table after a sorter or filter has been added? As an example, I set the row filter before adding anything to the table then add a value to the table with the following calls in

问题 In another thread I found this comparator (bottom of post) for sorting JTable columns that could be composed of integers, strings, or both. I cannot figure out how to apply it to my JTable. My table was using the auto created row sorter before. I set that to false and I am now using: TableRowSorter<MyTableModel> rowSorter = new TableRowSorter<MyTableModel>(); jtable.setRowSorter(rowSorter); rowSorter.setComparator(0, c1); I get an index out of bounds exception saying I am providing an invalid

问题 I have a JTable, and i want to sort rows sometimes by integer (size column), sometimes by String (file path). So i searched it on google and i've arrived here. i've known that i've to override a method of DefaultTableModel , called getColumnClass . So i link here my code. class Personal_model extends DefaultTableModel{ Personal_model(String[][] s,String[] i){ super(s,i); } @Override public Class<?> getColumnClass(int columnIndex){ if (columnIndex!=2) return String.class; else return Integer

问题 I want to search data from JTable when data found then I want to highlight table row. This code is work properly search record but I don't know what I do for highlight the row. String target = jTextField1.getText(); for(int row = 0; row < jTable1.getRowCount(); row++) for(int col = 0; col < jTable1.getColumnCount(); col++) { String next = (String)jTable1.getValueAt(row, col); if(next.equals(target)) { System.out.println("found");// here what change for highlight row. } } 回答1: The answer

问题 I am trying to get my JTable to sort null values at the end of the table. This is similar to a thread found at SO (How can i sort java JTable with an empty Row and force the Empty row always be last?) and OTN (https://forums.oracle.com/thread/1351003) but the answers in those threads aren't very clear to me. I did make a lot of progress using those answers, though, and I got as far as the SSCCE posted below. But I'm still trying to figure out how to get the null values (or, in the SSCCE I
