fgl_winmessage()

Displays an interactive message box containing text and OK button.

Syntax

fgl_winmessage(
   title STRING,
   text STRING,
   icon STRING )
  1. title defines message box title.
  2. text is the text displayed in the message box. Use '\n' to separate lines.
  3. icon is the name of the icon to be displayed.

Usage

The fgl_winmessage() function displays a message box to the end user.

Important: With front-ends implementing this function with the system dialog box API creating a modal window, the end user will have to close the modal window first, before continuing within the window of another program. Consider using a menu with "dialog" style instead, to not block other programs.

Supported names for the icon parameter are: information, exclamation, question, stop. Note that on some front-ends such as iOS devices, the native message popup window does not display an image.

On front-ends using a system dialog box API, the OK buttons will be automatically localized base on the operating system language settings. On other front-ends, the option buttons will be decorated depending on action default settings.

Example

IMPORT FGL fgldialog
MAIN
  CALL fgl_winmessage( "Title", "This is a critical message.", "stop")
END MAIN
