You can find the first child of a FXComposite by calling 

	child=composite->getFirst()

and subsequent siblings with:

	child=child->getNext()

until child==NULL.

Of course, no guarantee that they''re FXTextFields.  I recommend:


	textfield=dynamic_cast<FXTextField*>(child);
	if(textfield){

		...

	}

or:

	if(child->isMemberOf(&FXTextField::metaClass)){
		textfield=(FXTextField*)child;

		...

	}


If you KNOW they''re FXTextFields, you can of course omit the check and
simply use static_cast<FXTextField*>(child) instead, which is definitely
faster.

IIRC, you can use the #children method:

frame.children.each do |child|
   child.text = ""
end
