Pop-up windows – PB Docs 2019

Pop-up windows are typically opened from another window, which
in most cases becomes the pop-up window’s parent.

A pop-up window can display outside its parent window. It cannot
be overlaid by its parent. A pop-up window is hidden when its parent
is minimized and when its parent is closed. When you minimize a pop-up
window, the icon for the window displays at the bottom of the
desktop.

Using pop-up windows

Pop-up windows are often used as supporting windows. For
example, say you have a window containing master information, such as
film listings. You can use a pop-up window to allow a user to see
details of a particular entry.

Explicitly naming a
parent

In most cases, the window that opens a pop-up window becomes
that window’s parent. For example, if a script in w_go has this
statement, w_go is the parent of w_popup:

You can also explicitly name a pop-up window’s parent when you
use Open in this way:

For example, the following statement opens w_popup and makes
w_parent its parent:

However, there are also other considerations regarding which
window becomes the parent of an opened window.
