、あなたはあなたがのMouseListenerとのKeyListenerで、この2つの方式を組み合わせて試すことができます
JTable.getSelectedRow()
と
JTable.getSelectedColumn()
を持っています。
//global variables
JTable theTable = new JTable();//your table
boolean pressingCTRL=false;//flag, if pressing CTRL it is true, otherwise it is false.
Vector selectedCells = new Vector<int[]>();//int[]because every entry will store {cellX,cellY}
public void something(){
KeyListener tableKeyListener = new KeyAdapter() {
@Override
public void keyPressed(KeyEvent e) {
if(e.getKeyCode()==KeyEvent.VK_CTRL){//check if user is pressing CTRL key
pressingCTRL=true;
}
}
@Override
public void keyReleased(KeyEvent e) {
if(e.getKeyCode()==KeyEvent.VK_CTRL){//check if user released CTRL key
pressingCTRL=false;
}
}
};
MouseListener tableMouseListener = new MouseAdapter() {
@Override
public void mouseClicked(MouseEvent e) {
if(pressingCTRL){//check if user is pressing CTRL key
int row = theTable.rowAtPoint(e.getPoint());//get mouse-selected row
int col = theTable.columnAtPoint(e.getPoint());//get mouse-selected col
int[] newEntry = new int[]{row,col};//{row,col}=selected cell
if(selectedCells.contains(newEntry)){
//cell was already selected, deselect it
selectedCells.remove(newEntry);
}else{
//cell was not selected
selectedCells.add(newEntry);
}
}
}
};
theTable.addKeyListener(tableKeyListener);
theTable.addMouseListener(tableMouseListener);
}
