Something like this:
RibbonX:
<button id="InvisibleButton" getVisible="getRibbonVisible" />
C#:
public bool getRibbonVisible(IRibbonControl control) {
ribbonVisible=true;
return false;
}
private bool ribbonVisible=false;
private IRibbonUI ribbon; //assuming you set this with onLoad
void checkRibbonVisibility() {
ribbonVisible=false;
ribbon.InvalidateControl("InvisibleButton");
}
You only have to decide when to call checkRibbonVisibility(). Depending on the performance cost of executing the callback (you might have to do some checking to see what it is), you could do this whenever your event gets triggered, but before you execute your parsing. Or you could do it with a timer every 5-10 seconds or longer.
The callback will be executed once your tab is brought into the foreground. There is no guaranteed order of execution for callbacks, so you should have ribbonVisible=true on the top of all your callbacks for the controls on that tab. While your tab is visible, getRibbonVisible will always be executed right away after you called checkRibbonVisibility. When your tab becomes invisible, it won't execute the callback until it becomes visible again.
You can do this approach with any of your controls and callbacks, there is no need to create a special one for it. However, I'd suggest you create a dedicated one that has only one callback (your other controls prob. have more than one each) and hence has the minimum performance impact possible.
As I said before, you can use the Accessibility API alternatively to query what the foreground tab is. I have only played around with this a little bit, so I can't give you more than a few hints as to how to get started with it.
That's really it though. There are no events in the object model that would allow you query this kind of information directly. It's either one of those two hacks.

How would the hidden button approach work?
