Class WMessageBox

public class WMessageBox extends WDialog
A standard dialog for confirmation or to get simple user input.

The messagebox shows a message in a dialog window, with a number of buttons. These buttons may be standard buttons, or customized.

A messagebox is (usually) modal, and can be instantiated synchronously or asynchronously.

When using a messagebox asynchronously, there is no API call that waits for the messagebox to be processed. Instead, the usage is similar to instantiating a WDialog (or any other widget). You need to connect to the buttonClicked() signal to interpret the result and delete the message box.

The synchronous use of a messagebox involves the use of the static method, which blocks the current thread until the user has processed the messabebox. Since this uses the WDialog#exec(), it suffers from the same scalability issues as well as limitations. See documentation of WDialog for more details.

This will show a message box that looks like this:
