[英]How do i set focus to the first cell of jtable and which the first column I have also set the CellEditor to a comboBox
在jtable的第一列中,我设置了setCellEditor(新的DefaultCellEditor(comboBox)。
我想要的就是打开表时,找到第一个具有可编辑组合框的单元格,其中光标闪烁,可供输入。
这是我已完成的工作的代码。
try {
//Already registered so open mainWindow
UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
final mainWindow mainn = new mainWindow();
//get the institution name and display it as the title
String companyName = dbutils.checker.getCompanyName();
//disable all items on system
disable();
mainn.setTitle("[" + companyName + "]");
mainn.setExtendedState(Frame.MAXIMIZED_BOTH);
TableColumn items = mainWindow.salesTable.getColumnModel().getColumn(0);
final JComboBox comboBox = new JComboBox();
comboBox.addItem("250AZ0002C20140725");
comboBox.addItem("250AZ0001C20140725");
comboBox.addItem("250AZ0003C20140725");
comboBox.addItem("250AZ0004C20140725");
comboBox.setEditable(true);
items.setCellEditor(new DefaultCellEditor(comboBox));
ComboBoxEditor editor = comboBox.getEditor();
JTextField textField = (JTextField)editor.getEditorComponent();
textField.setCaretPosition(0);
SwingUtilities.invokeLater(new Runnable() {
@Override
public void run() {
mainWindow.salesTable.requestFocus();
comboBox.requestFocus();
mainWindow.salesTable.changeSelection(0, 0, false, false);
mainWindow.salesTable.editCellAt(0, 0);
}
});
readBarcode();
mainn.setVisible(true);
} catch (Exception ex) {....}
JTable非常简单,默认情况下始终具有焦点。 要使焦点移到单元格上,可以使用Jtable.setSurrendersFocusOnKeystroke(true)方法。
