Hot spots are special widgets that are always invisible in the web browser. Use one when you need to add interactivity to an area of your design where there are no other suitable widgets, such as when adding a hot zone to a particular area of an image or adding an anchor location to a long page.
热点是特殊的元件，它们始终在Web浏览器中不可见。 当你需要在没有合适设计区域的元件上增加交互事件时请使用，例如在将热点区域添加到图像的特定区域或将锚点位置添加到长页面时。
Tip提示
You don't need a hot spot to add interactivity to a group of widgets. Instead, place the widgets into a widget group and configure your interactions on the parent group's events.你不需要热点即可向一组部件添加交互性。 将窗口部件放入窗口部件组中，并在父组的事件上配置你的交互。
Creating Hot Spots创建热点
The hot spot widget is available in the Common section of the Default widget library. Drag one from the Libraries pane and drop it onto the canvas to add it to your design.热点窗口部件位于“默认”窗口部件库的“通用”部分中。 从“库”窗格中将其拖放到画布上，以将其添加到你的设计中。
The Hot Spot Mask热点遮罩
Because hot spots are invisible, they're covered with a green mask by default so that you can see them on the canvas. You can toggle the mask at View → Masks in the application menu.由于热点是不可见的，因此默认情况下会用绿色遮罩覆盖热点，以便你可以在画布上看到它们。 你可以在应用程序菜单的“视图”→“遮罩”中切换遮罩。
