More than one widget , how to refresh once together?

[Breeze1]

In Screen, I have 3 or more widgets , they are the same type of widget, but can not make them in one container. In normal , I have to invalid one by one. Now , I need them to refresh together, how do I do?

the refresh rate is so high that invalidating them one by one should be fine?

another option could be to update the widgets when you enter the screen. use the activate method in the presenter to do that.

For low power reason, we slow down the refresh rate. Now the refresh rate is no more than 10. If invalidating one by one , it will stuck.
