Displays a deletion message box, with up to three buttons.
Displays a error message box, with up to three buttons.
Displays a information message box, with one button.
Displays a question message box, with up to three buttons.
Displays a warning message box, with up to three buttons.

All Message functions can have up to three buttons:

  • The first button is always the default button.

  • The last button is always the cancel button.

When invoked with only one argument, then there is only one "OK" button.

Message boxes are modal, i.e. the program is paused until one button is clicked.

When the message box is closed, the index of the clicked button is returned.

The message text is interpreted as (a subset of) HTML. Among the things you need to keep in mind are:

  • You can add emphasis/markup to your text by the usual tags:

    Message("(p And Not p) is <b>false</b>")

  • Line breaks are HTML-like:

    Message("Line\\nbreak") ' *won't* work
    Message("Line<br>break") ' will

  • Characters with special meaning in HTML need to be quoted. The following line:

    Message("(2 < 3) is true")

    may result in the "< 3..." part being swallowed away as invalid HTML (seen with gb.gtk and gb.gtk3), but

    Message("(2 &lt; 3) is true")

    will work everywhere.
