• shape (integer) – the BalloonTip shape. It can be one of the following:
  
  

  integer parameter settings

  Shape Flag	Hex Value	Description
  BT_ROUNDED	0x1	BalloonTip will have a rounded rectangular shape.
  BT_RECTANGLE	0x2	BalloonTip will have a rectangular shape.

• tipstyle (integer) – the BalloonTip destruction behavior. It can be one of:
  
  

  integer parameter settings

  Tip Flag	Hex Value	Description
  BT_LEAVE	0x3	BalloonTip will be destroyed when the user moves the mouse outside the target window.
  BT_CLICK	0x4	BalloonTip will be destroyed when the user click on BalloonTip.
  BT_BUTTON	0x5	BalloonTip will be destroyed when the user click on the close button.

Raise :

Exception in the following cases:

• The message parameter is an empty string;
