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 < 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")
