How can I get the number (count) of, let's say, text widgets from a sidebar?

for eg. if I drop 4 text widgets in the sidebar, I want to get this number somehow from another widget

Call wp_get_sidebars_widgets(), and loop through each sidebar. Off the top of my head, text widgets have an ID like widget_text-$i.

All widgets have a numeric value on the end don't they, to indicate what instance of the widget it is(assuming a given widget supports multiple instances). Looks like the sidebar array stores widget names minus the widget_ prefix though, so text widgets have a name like text-1, text-2 and so on.. – t31os Dec 12 '10 at 11:42
