trouble with tooltips for jcomponent located inside jtable cell
So heres my problem:
I have a jtable which has a jpanel inside its cells for 1 column. Now Inside this jpanel is a textbox and a button. Basically, what i want to do is have a tooltip show up when the mouse hovers over the textbox only, not when the mouse is over the entire cell which contains the jpanel.
I tried adding a mouseMotionListener to the textbox, but that only works if the textbox has focus, which means it needs to be clicked on first, which isn't what i want.
So then I tried something like this:
public String getToolTipText(MouseEvent me){
int row = rowAtPoint(me.getPoint() );
int column = columnAtPoint(me.getPoint() );
}
with the getValueAt() method, but the problem is, I still cant figure out if the mouse is over the textbox or not, and thus the tooltip shows for the whole cell. Here is a working example (note: I got this example from this forum, and tweaked it to my liking):
import org.jdesktop.swingx.table.ColumnHeaderRenderer;
import javax.swing.*;
import javax.swing.table.TableCellEditor;
import javax.swing.table.TableCellRenderer;
import java.util.EventObject;

table =new JTable(moa,new String[]{"Header1","Header2"}){
public String getToolTipText(MouseEvent me){
int row = rowAtPoint(me.getPoint() );
int column = columnAtPoint(me.getPoint() );
MultiObject o = (MultiObject) getValueAt(row, column);
return o.fText;
}
};

table.getColumnModel().getColumn(0).setCellRenderer(tcr);

any ideas? thanks!
