This Java tips illustrates a method of making a tool tips appear immediately. By default, when the cursor enters a component, there is a 750-millisecond delay before the tool tip is displayed. This example demonstrates how to show the tool tip immediately.

  // Get current delay
    int initialDelay = ToolTipManager.sharedInstance().getInitialDelay();
    
    // Show tool tips immediately
    ToolTipManager.sharedInstance().setInitialDelay(0);
    
    // Show tool tips after a second
    initialDelay = 1000;
    ToolTipManager.sharedInstance().setInitialDelay(initialDelay);
