Setting the Location of a Tool Tip
By default, when a tool tip of a component appears, its northwest
corner appears at the same x-coordinate as the cursor and 20 pixels
lower than the y-coordinate of the cursor. To change this default
location for a component, the
getToolTipLocation() method of the component must be overridden.
// Set the location of the tool tip such that its nw corner
// coincides with the nw corner of the button
JButton button = new JButton("My Button") {
public Point getToolTipLocation(MouseEvent event) {
return new Point(0, 0);
}
};
// Set the location of the tool tip such that its nw corner
// coincides with the bottom center of the button
button = new JButton("My Button") {
public Point getToolTipLocation(MouseEvent event) {
return new Point(getWidth()/2, getHeight());
}
};
// Use the default tool tip location
button = new JButton("My Button") {
public Point getToolTipLocation(MouseEvent event) {
return null;
}
};
// Set the tool tip text
button.setToolTipText("aString");
