How do popup blockers capture popup events

[BillaBundook]

Hi there

I have seen many popup blockers that capture windows from browser and prevent them from comming up.
Can anybody please tell me how these programs capture the windows and prevent them from displaying.
Thanks.

Browser control has an event for a new window being created.

When you do it, do it right.
