Question

ContainerController Transparent Background

I have a need to make the size of the transparent background added to the ContainerController smaller so I can layer other components under the controller but also be able to accept mouse events.

I noticed above attachTransparentBackgroundForHit there is this comment:

/** No mouse clicks or moves will be generated for the container unless it has a background covering its area.  Text Layout Framework

* wants those events so that clicking on a container will select the text in it.  This code

* adds or updates (on size change) that background for Sprite containers only. This may cause clients problems

* - definitely no hits is a problem - add this code to explore the issues - expect feedback. 

* We may have to make this configurable. @private */

One thing that would be nice to have would be is a transparentBackgroundTopOffset and transparentBackgroundBottomOffset.  Then change values of the local variables bgheight and bgy to accommodate for the offsets.

You can accomplish your goals by subclassing ContainerController and overriding the function.

Hope that helps,

Thanks Richard,

I noticed a bunch of properties in the function were private but now that I look most of them are only referenced inside of attachTransparentBackgroundForHit.  The only exception to that is _minListenersAttached but I guess I could override attachContainer and detachContainer and store my own private variable.

Thanks,

Joel Marks
