Volume 7A: XView Programming Manual

defines attributes that give hints to the window manager to provide such features as title bar

information, resize corners, and so on. If a non-OPEN LOOK window manager is used, there

is no guarantee that these attributes will have any effect.

Pop-up frames are typically used to perform one or more transient functions. They are not

intended to stay up after the set of functions has been completed, although they might remain

up if the user or the application so chooses. This functionality can be handled by a pushpin at

the upper-left corner of the frame. There are different kinds of pop-up frames:

Command Frames give operands and set parameters needed for a command. This is

implemented as a subframe that contains a default panel.

Help Frames display help text for the object under the pointer. This is implemented

as a text subwindow within a subframe.

Notices are special pop-up windows that are used to confirm requests, to dis-

play messages and conditions that must be brought to the user’s atten-

tion and handled immediately. These require immediate attention and

can suspend the application by disallowing the focus from leaving the

Notice.
