Remarks

A message box is a small window that displays a caption, a message, an icon (chosen from a predefined set of icons), and push buttons (selected from a variety of predefined combinations). It provides an easy alternative to the dialog window when all you require from the user is a simple response. Message boxes require no sizing, positioning, or event handling. In addition, message boxes can be application modal (no processing can continue in the application until the user has acknowledged the message box), or it can be modal in relation to its owner window (no processing can continue in its owner window until the user has acknowledged the message box).

Examples

The following example handles a QueryClose event:

Copy

1METHOD QueryClose(oEvent) CLASS TopAppWindow
2oTB := TextBox{SELF, "Quit", "Do you really want to quit?"}
3oTB:TYPE := BOXICONQUESTIONMARK + BUTTONYESNO
4IF (oTB:Show() = BOXREPLYYES)
5RETURN TRUE // Quit application.
6ELSE
7RETURN FALSE
8// Don't quit the application.
9ENDIF
