For example, you can use a Dialog widget whenan application requires a small piece of information, such as a filename, from theuser.

The first line contains a descriptionof the function of the Dialog widget, for example, the string Filename:. The secondline contains an area into which the user types input. The third line can containbuttons that let the user confirm or cancel the Dialog input. Any of these areas maybe omitted by the application.When creating a Dialog widget instance, the following resources are retrieved fromthe argument list or the resource database:Name Class Type Notes Default Valueaccelerators Accelerators AcceleratorTableancestorSensitiveAncestorSensitiveNULLBoolean D Truebackground Background Pixel XtDefault-Background103
