	OK, so assuming you have a single callback for the tab widget which is fired
	when someone clicks the group4 tab, it can access the data from the other 3 groups
	and apply it to group 4's browser.

	Set names for the different widgets so they are each assigned variables, and access
	the variables to read from/write to the widgets to update their data.

	To assign variable names to e.g. the browser widget, open the properties for that
	widget, and under C++ -> Name: type in a variable name to use for it. That will be
	assigned by fluid's code that sets up the widget, and those names can be accessed
	from your tab callback. Be sure the pulldown to the right of the above descibed
	Name: prompt is set to "global", so the variable is defined as a global.

	For this the only callback you'd need is the one you have already for the tab,
	and just have that callback directly access the widgets to read/write them.

	You could get more complicated and make the tab group widgets modular subclasses
	that don't use globals. In that case, make an API in each class that lets you
	access the data within each group and return it as an array of strings in the
	format you want, and then your tab callback would invoke your subclass methods
	to accumulate the array of strings, and then pass that array to the group 4
	widget that would apply those strings in whatever way to the browser.
	Presumably each subclass would have a way to save out its widget's settings
	into text, and if need be, each could also have a way to apply those strings
	to the widgets, updating them based on the array's contents. This is basically
	"messaging", just without the formal structure of a centralized messaging system.
