问题 I have a cell editor that contains a little button and then a textfield that can be used to edit the value inline I use setSurrendersFocusOnKeystroke(true) and a focus listener in order to allow a user to start editing immediately from the keyboard, but the trouble is the fisrt key pressed seems to get consumed rather being added to the text field, how can I prevent this ? Full self contained example below import javax.swing.*; import java.awt.*; import java.awt.event.FocusEvent; import java

问题 I want to ask some questions regarding editing cell in a table. Currently my practices of doing cell editing in a table is by double-clicking the cell to make the cell editable for text input. For the single-clicking, it will select the row instead. It just like Excel behaviour of cell editing. What I see in some of JIDE demo , some of the table can be editable using single-click such as "EditableTableHeaderDemo" and some of it can be editable using double-clicking such as JideTableDemo. What

问题 For putting a JSlider into a JTable I wrote am AbstractCellEditor which implements a TableCellRenderer and a TableCellEditor . It gets initialized with values from 0 to 100. I have the strange behaviour that when I first click onta a slider it jumps to the maximum. The second weird behaviour: I've added a ChangeListener . This Listener gets only called if I first click into the slider. A second click (which also changes the value) doesn't cause this event. Why? public class SliderTableColumn

问题 If user starts pressing keys using keyboards then JTable is supposed to be searched the matching text for him and if user double clicks on cell then Table should allow him to edit the text. And the issue is - Table is only searching text when the table is in non-editable mode and if Table is editable and user starts typing the text-using keyboard, cell is allowing him to edit the cell rather then search. Mr mKorbel has just solved my issue to allow edit only if double click on Table cell.

问题 I'm trying to make a table that works like Excel. Meaning, when a user starts to insert data into the cells the content into them is selected and changed by the new data inserted. 回答1: You can create a custom TableCellEditor for your table. This class will have an instance variable of a TextField , lets call it textField . Then the getTableCellEditorComponent method could look like this: public Component getTableCellEditorComponent(JTable table, Object value, boolean isSelected, int row, int

问题 i'm using a JSpinner like a table cell editor, i have one annoying problem: The cell remains in NON-editable mode until i click into it, for NON-editable i mean that i can't write into it(it has not focus so it doesn't accept inputs keyboard) but i can change the value with up-down arrows(of keyboard). So, what i have to do to focus my table cell as soon as i press a key when it is selected? Except for that problem my SpinnerEditor class works quite well. Thanks all. 回答1: Here's a complete

问题 I have defined cell editors for the two columns in my table in the following manner: Java Code: JComboBox combo = new JComboBox(); //code to add items to the combo box goes here. JTextField textField = new JTextField(); textField.setHorizontalAlignment(JTextField.RIGHT); TableColumn column = myJTable.getColumnModel().getColumn(0); column.setCellEditor(new DefaultCellEditor(combo)); column = myJTable.getColumnModel().getColumn(1); column.setCellEditor(new DefaultCellEditor(textField)); The

问题 I a swing application in which i have a table inside it i'm putting a panel that can contain a button.The code is follow public class MyCellDataRenderer implements TableCellRenderer, TableCellEditor { @Override public Component getTableCellRendererComponent(JTable table, Object value, boolean isSelected, boolean hasFocus, int row, int column) { MyCellData myCellData = (MyCellData) table.getValueAt(row, column); JPanel panel = GridBagHelper.createPanel(); if (myCellData.isATableHeader()) {

问题 First of all, apologies for posting something perhaps a bit excessively specific, but I'm not very experienced with Swing, and can't seem to find good examples that fit my needs. So I'm trying to figure out the best way to implement the a dynamic GUI for choosing filtering criteria in Swing: The underlying model is a class containing a list of criteria that can be negated (i.e. applied with a NOT-prefix), and a property indicating whether these should be combined with AND or OR. The GUI would

问题 I have a cell editor that contains a little button that can be double clicked on to bring up an edit dialog, and then a textfield that can be used to edit the value inline (the popup is required to allow editing of additional values, only the first is shown in the JTable). When user clicks on field everything is okay, but if they tab into the field they textfield doesn't receive focus and they cannot edit the field unless they click on it with the mouse. I tried fiddling with the various
