Requesters are a special kind of windows. They either confront the user with some information or request some information. Requesters always interrupt the user's normal work flow, so they should only be used either to inform him of some important event or to request information without which the application can't continue. This kind of requester is called a modal requester.

Examples of informational requesters are requesters that report errors (like failing to open a file) or about requesters which show information about the program, when requested by the user.

Like the name indicates, requesters can also request information from the user, like a filename (using file-requesters), his name or a simple yes/no decision ("Really quit application?").

Requesters should only be used if an application can't go on without the intended interaction with the user, be it acknowledgement that the user has learned a certain fact, be it that the user provides a necessary piece of information, or be it that displaying the requester is the current task the user selected for the program. Therefore, most requesters will block the application. That is to say: An application usually will not accept any input, except that in the requester. An exception are requesters that are explicitly requested by the user, like most file-requesters or about-requesters. Normally, these do not block the application.

Easy Requesters

The so-called easy requesters are simple requesters. They can be used to either provide information or to ask for a choice. The number of choices is limited to 256, but it is generally a bad idea to have more than about five different choices. You also have to take into account that the width of the screen is limited.
