Non-modal or modeless dialog boxes are used when the requested information is not essential to continue, and so the window can be left open while work continues elsewhere. A type of modeless dialog box is a toolbar which is either separate from the main application, or may be detached from the main application, and items in the toolbar can be used to select certain features or functions of the ...
Modal windows are sometimes called heavy windows or modal dialogs because they often display a dialog box. User interfaces typically use modal windows to command user awareness and to display emergency states, though interaction designers argue they are ineffective for that use. [1] Modal windows are prone to mode errors. [1] [2] [3]
Modal alert dialogs are prone to produce mode errors due to their unrequested nature. A study to appear at the Proceedings of the Human Factors and Ergonomics Society showed that when a user dialog appears, the primary goal of users is typically to get rid of them as soon as possible [2] even without any analysis of the causes for the dialog ...
A message window, or dialog box, is a type of child window. These are usually small and basic windows that are opened by a program to display information to the user and/or get information from the user. They almost always have one or more buttons, which allow the user to dismiss the dialog with an affirmative, negative, or neutral response.
In his book The Humane Interface, Jef Raskin defines modality as follows: "An human-machine interface is modal with respect to a given gesture when (1) the current state of the interface is not the user's locus of attention and (2) the interface will execute one among several different responses to the gesture, depending on the system's current state."
The vicious cycle is broken through EDT entering a new message loop, which dispatches the messages as per normal until "modal dialog is over" arrives and normal message processing resumes from the blocked position in the component action.
The user attention is not in the dialog window but in the process of saving a file (focus on the action, not the interface), thus the window itself is always modal. (The dialog would not be modal in the Raskin's sense while the user is dragging the window, for example; but that is a marginal case).
Confirmation dialog (sometimes called a warning alert box or chicken box) [1] [2] is a dialog box that asks user to approve requested operation. Usually this dialog appears before a potentially dangerous operation is performed (program termination, file deletion, etc.) Typically confirmation dialog boxes have two buttons (e.g.
