MessageDialog

MessageDialog[expr]
puts up a standard message dialog that displays expr together with an OK button.

MessageDialog[expr, {lbl₁:>act₁, lbl₂:>act₂, ...}]
includes buttons with labels lbl_i, which evaluate the corresponding act_i if clicked.

MessageDialog returns immediately, but the dialog it generates remains up until one of its buttons is pressed, or the dialog window is closed.

MessageDialog[expr] generates a dialog that includes an OK button. Pressing Enter or Esc is taken to be equivalent to pressing the OK button.

MessageDialog places buttons automatically, outside the area used to display expr.

MessageDialog by default puts up a notebook with a typical message dialog appearance. The option settings include WindowFloating->False, WindowSize->All and WindowTitle->None.

MessageDialog by default puts up a dialog in the middle of the main display screen. Explicit settings for WindowMargins override this.

MessageDialog returns a NotebookObject corresponding to the notebook it creates.

If Mathematica is run without a notebook front end, MessageDialog[expr, ...] prints expr in textual form, without any buttons or other controls.
