Message (gb.qt4)

This class is used for displaying message boxes.

This class is static.

This class can be used as a static function.

Static properties
ColoredButtons   Return or set if colored buttons are used.
DefaultButton   Return or set if the first button of the message box is the default one.
Style   There is currently only one option: "flat".
Title   Returns or sets the title of the next message box.

Static methods
Delete   Displays a deletion message box, with up to three buttons.
Error   Displays a error message box, with up to three buttons.
Info   Displays a information message box, with one button.
Question   Displays a question message box, with up to three buttons.
Warning   Displays a warning message box, with up to three buttons.

Message boxes come in the following flavors: All message functions show a different image to highlight the message type. The image above shows Message.Warning() and its warning image. Using Message() is the same as using Message.Info().

All message functions apart from Message() and Message.Info() can have up to three buttons.

The last button is always assumed to be the cancel and the default button.

This is the same button that is triggered when you close the message box with the ESCAPE key.

In other words, the default action should always do nothing.

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 : 1 for the first button, 2 for the second button, 3 for the third one.

The message text is interpreted as Rich text.

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 can be standard linefeed "\n" or HTML-like:

    Message("Line<br>break")
    Message("Line\nbreak")
    Message("Line" & gb.Lf & "break")
    

  • 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.

  • If you want to show plain text and not use HTML markups you can use the Html$ function to convert your message to HTML viewable format.

    For example:

    Message(Html$("(2 < 3) <this line shows as you see it> \nand <b>this line is not bold but displays the markup</b>"))
    

Examples

PRINT Message("Program v0.3<br>Version of 2006-03-28")
PRINT Message.Info("Program v0.3<br>Version of 2006-03-28", "Fine")
PRINT Message.Warning("Your changes will be lost", "Save", "Ignore", "Cancel")
