Requesters

A window that appears on-screen prompting a user response is called a requester. These windows usually contain text explaining what the request is for and what the user must do to continue an operation.

Action Requesters

A specific type of requester that asks the user about proceeding with an action in process. These windows have buttons labeled usually with two or more of the following: Ok, Continue, Retry, Cancel, or Fail, but may contain more specific buttons, depending on action to be taken. Underlined letters on the requester buttons indicate keyboard shortcuts that can be used instead of using the mouse. The example on the right shows a system shutdown requester, which is an action one.

Message Requesters

These requesters alert the user about something that has occurred in a program or within the system itself, and require only an acknowledgment by clicking on a button.

Text Requesters

The user is required to provide information through the keyboard into a box within the window.

File Requesters

Used specifically to identify a file, usually for opening or saving a document, this requester usually contains a list of files and drawers.

This requester has several gadgets and a list of files and directories. The user may also type in a path and filename in the provided text field. Usually, however, most users will simply scan through a list, dragging the scroll bar as necessary (scroll arrows are provided as well) to locate a given file. There are several extra gadgets used with this requester.

• "/" (Parent): This gadget indicates the current directory's parent directory. If the list currently displays the root of a given device, using this gadget will act the same as the Volumes gadget.
• "<" (Back): During the process of browsing through directories, the back gadget can be used to re-list the last directory viewed in the file requester.
• ">" (Forward): Similar to the back gadget, the forward gadget browses through directories in the file requester history.
• ":" (Volumes): When used, the volume gadget will display a list of devices available to MorphOS. This includes USB devices, assigns, and hard drive partitions. When clicking on a device or a drawer, it's contents are then displayed. Information about the files and directories are also displayed within the lister.
• Ok: Will load or save the selected file. This result can also be achieved by pressing the Enter key. Double-clicking on the file-name will open a file, but is inactive for saving. The Ok button may be labeled Ok, Save, Load, or something else based upon a given application.
• Cancel: Terminates the action and removes the requester from the screen.
• File Pattern or Pattern: An optional text input gadget, usually labeled Pattern, allows the use of MorphOS Shell pattern matching to filter the list of files. The text in this gadget is often called a pattern statement.
