short cuts to jump between table columns
I have setup actions that would allow the user to use shortcut keys to jump between columns of a JTable. My code is as follows:
publicclass HotkeyActionListenerextends AbstractAction{
protected String m_cmd ="";
protected AppIFace m_appIFace =null;
public HotkeyActionListener(String actionCommand, AppIFace appIFace){
super(actionCommand);
m_cmd = actionCommand;
m_appIFace = appIFace;
}
publicvoid actionPerformed(ActionEvent event){
if (m_cmd.equals(HotkeyConstants.FOCUS_FIRST_COLUMN)){
m_appIFace.requestFocusOnFirstColumn();
}elseif (m_cmd.equals(HotkeyConstants.FOCUS_SECOND_COLUMN)){
m_appIFace.requestFocusOnSecondColumn();
}elseif{
....
}
}
publicclass MyTableFrameextends JFrame{
....
publicvoid setupTableShortCutKeys(){
setShortCutKey(HotkeyConstants.FOCUS_FIRST_COLUMN, m_appIFace);
setShortCutKey(HotkeyConstants.FOCUS_SECOND_COLUMN, m_appIFace);
...
}
publicvoid setShortCutKey(String type, AppIFace iFace){
HotkeyActionListener keyAction =new HotkeyActionListener(type, iFace);
KeyStroke keyStroke = Configuration.getKeystroke(type);
String tooltipTxt = Configuration.getToolTip(type);
InputMap imap = component.getInputMap(JComponent.WHEN_IN_FOCUSED_WINDOW);
ActionMap amap = component.getActionMap();
imap.put(keyStroke, tooltipTxt);
amap.put(tooltipTxt, keyAction);
}
}
publicclass MyFrameextends AppIFace{
publicvoid requestFocusOnFirstColumn(){
SwingUtilities.invokeLater(new Runnable(){
publicvoid run(){
setFocusOnColNo(0);
}
});
}
publicvoid setFocusOnColNo(int colNo){
CellEditor ce = table.getCellEditor();
if (ce !=null){
ce.stopCellEditing();
}
int selectRow = getCurrentSelectedRow();
table.setRowSelectionInterval(selectRow, selectRow);
table.setColumnSelectionInterval(colNo, colNo);
table.scrollRectToVisible(new Rectangle(0, table.getRowHeight() * selectRow, 20, table.getRowHeight()));
table.requestFocus();
}
}
At runtime, what I found is this:
When I've selected a non-editable cell on the table and I press a short-cut key to jump to some other column, all is ok and focus goes to the correct cell in another column.
But when I've selected an editable cell and I press the short-cut key, two things happen
1. The selected cell goes into edit mode
2. The focus shifts to the other cell. But the cell in #1 now exits edit mode and focus shifts back to the first cell.
How can I fix this so that the my short-cut keys always work, regardless of whether the selected cell is editable or non-editable.
thanks,
