问题 In my implementation of JTable . I have to keep some columns editable and some columns UN-editable so I have override isCellEditable - @Override public boolean isCellEditable(int row, int col) { if (col == uneditableColumn) { return false; } return bEdit; } Now my requirement is to allow edit the cell only on Double click i.e. if user double clicks on cell then only it comes into editable mode. For this - I will have to make your own CellEditor and override. public boolean isCellEditable(

问题 I am reading in data using DOM Parser to update a JTable . I have a Column (ValidValues) that may not necessarily be located in the XML. However, if this tag is located when reading in from the XML, I take the value and use this to from an SQL query to return a vector of the records available. I then wish to populate the JTable with a specific combo box of the values returned on the correct row that the tag was read. E.G I may not read a tag until the 17th row has been read in from the XML

问题 I have here a code I found in the stackoverflow which allows the table to have a custom cell editor as JTextField .

问题 I am using a JXComboBox as cell editor in a modified JXTable / RXTable with custom models. I am noticing a delay when starting to type inside the cell. Edit : also, if you type more keys faster in the box, the first one you typed will not appear first in the editor. The table: import java.awt.*; import java.awt.event.*; import java.util.*; import javax.swing.*; import javax.swing.table.*; import javax.swing.text.*; import org.jdesktop.swingx.JXTable; /** * This is a modified version of

问题 I am creating a app in Java. I need to provide additional behavior when editing of a cell in a JTable. So ideally this will happen when the cell loses focus after editing. Depending upon some post processing I might reset the value of the cell. I tried using a a Cell Editor but it is not giving me the desired behavior. In the default JTable only when I Double click a cell it becomes editable. But in my implementation of CellEditor the cell becomes editable as soon as it comes into focus. Here

问题 Why is the last item blank? I only have 3 items (it's a tri-state boolean editor). Can a CCombo achieve this solid Combo look and feel? As a combo cell editor, I would prefer the regular Combo , BUT: Can this Combo be used as CellEditor , while fitting the table row height? (maybe making the Font smaller?) 回答1: The default visible item count for CCombo is 5, try calling setVisibleItemCount(3) . CCombo does not support much customization. It always sets the same colors for the list and the

问题 I have a JXTable compound of 6 columns and two of them are JCheckBox . I would like to have the following behavior: If the first checkbox is checked, the second checkbox is enabled and can be checked or not. If the first checkbox is unchecked, the second must be disabled and unchecked. I edited an image with Photoshop to show the desired result: For the CheckOne and CheckTwo columns i use a custom TableCellEditor and TableCellRenderer : public class CheckBoxCellEditor extends
