Tip pointer positioning

The Tooltip pointer can be attached or detached from the Tooltip by using the showTipPointer property. Pointer positions can be adjusted using the tipPointerPosition property that can be assigned to one of the following values:

Auto
Start
Middle
End

The following code example illustrates how to set the pointer to the start position of the Tooltip.

By default, tip pointers are auto adjusted so that the arrow does not point outside the target element.

Dynamic positioning

The Tooltip and its tip pointer can be positioned dynamically based on the target’s location. This can be achieved by using the refresh method, which auto adjusts the Tooltip over the target.

Mouse trailing

Tooltips can be positioned relative to the mouse pointer. This behavior can be enabled or disabled by using the mouseTrail property. By default, it is set to false.

When mouse trailing option is enabled, the tip pointer position gets auto adjusted based on the target, and other position values like start, end, and middle are not applied (to prevent the pointer from moving out of target).

Setting offset values

Offset values are set to specify the distance between the target and tooltip element. offsetX and offsetY properties are used to specify the offset left and top values.

offsetX specifies the distance between the target and Tooltip element in X axis.
offsetY specifies the distance between the target and Tooltip element in Y axis.

The following code example illustrates how to set offset values.
