如何为图像控制火花设置边距

Question

<s:Image id="loader1" top="50" source="@Embed(source='logo.png')"/>

top属性不起作用，如何对图像进行边距处理？

Answer 1

Since your image is inside a VBox and you want only to pad the Image and not the other components, here are some options:

• Put the Image inside a Group : the VBox wil layout the Group vertically and the Image will be positioned 50px from the top of the Group
• Put a Spacer between the Image and the component before it and give it a height of 50px.
• If the Image is the first element, you can set paddingTop="50" on the VBox.

Side note: you'd better use s:VGroup instead of mx:VBox since you seem to already use Spark components: it has better performance.
