Custom tooltip component

The tooltip In Flex is a rectangle box with a text box. You can modify the style to set its size and background, font color, but cannot change its shape. If you want a tooltip such as a pentagram, You have to customize it. The following is a brief introduction to the custom tooltip method. The procedure is the same as that of other custom components. Because tooltip itself is a component, you only need to implement the itooltip interface

Create a component named mytooltip:

implements = "MX. core. itooltip "
width =" 500 "Height =" 100% "backgroundcolor =" # ffd7ff "borderstyle =" solid "cornerradius =" 5 ">

[Bindable]
private VaR _ text: string;
Public Function get text (): string
{< br> return this. _ text;
}< br>
public function set text (value: string): void
{< br> This. _ text = value;
}< br>]>

ThenProgramThe tooltip is used to listen to the tooltipcreate event in the component to display the tooltip. This event is called before the tooltip is created. Therefore, you can create a custom tooltip here, if you want to locate the position of the tooltip, you can listen to its tooltipshow event, which is called when you want to display the tooltip
