Class Dialog

Known Direct Subclasses:

public class Dialog
extends Window

Dialog boxes are a convenient way to prompt the user for a small amount of input, to display a message, ask a question, or anything else that does not require extensive effort on the user's part.

GTK+ treats a dialog as a window split vertically. The top section is a VBox, and is where widgets such as a Label or a Entry should be packed. The bottom area is known as the actionArea. This is generally used for packing buttons into the dialog which may perform functions such as cancel, ok, or apply. The two areas are separated by a HSeparator.

A 'modal' dialog (that is, one which freezes the rest of the application from user input), can be created by calling Window.setModal(boolean) on the dialog.

If you want to block waiting for a dialog to return before returning control flow to your code, you can call run(). This function enters a recursive main loop and waits for the user to respond to the dialog, returning the response ID corresponding to the button the user clicked.
