A custom dialog is a window for displaying information or providing a pop-up for a specific task within an interface. It is created by dropping a custom dialog icon on the workspace. A custom dialog might be "connected" to a button or a menu in a main window, causing the pop-up dialog to be displayed when the button is clicked or a menu item is chosen. A custom dialog cannot be closed to an icon.
The status region includes the name of the module the dialog is part of and indicates when the dialog object is selected. It does not appear in the compiled application.
Examples of custom dialogs used in building App Builder include the File Selection Dialog, the Project Name and Module Name dialog boxes, all of the editors, and the message dialog boxes.
