; NAME: DIALOG_MESSAGE
;
; PURPOSE:
;
; This function try to reproduce the IDL's DIALOG_MESSAGE behavior
; using "zenity" or "wxwidgets"
;
; zenity, under GNU GPL, is available on most Linux distributions and
; and also on OSX (tested) and MSwin (not tested ?). It is better to
; have zenity version >= 2.23.1.
;
; wxwidgets version >= 2.8
;
; CATEGORY:
;
; CALLING SEQUENCE:
;
; resu_list=DIALOG_MESSAGE( Message_Text [, TITLE=string]
; [, /ERROR | , /INFORMATION | , /QUESTION] <<-- the main options
; [, /CANCEL] [, /CENTER] [, /DEFAULT_CANCEL | , /DEFAULT_NO]
; [,DIALOG_PARENT=widget_id] [, DISPLAY_NAME=string] [, RESOURCE_NAME=string])
;
; INPUTS:
; Message_Text: A scalar string or string array that contains the text of
; the message to be displayed. If this argument is set to an array of strings,
; each array element is displayed as a separate line of text.
;
; OPTIONAL INPUTS: none
;
; KEYWORD PARAMETERS:
; CANCEL: Set this keyword to add a "Cancel" button to the dialog.
; CENTER: Set this keyword to center the dialog on the screen.
; DEFAULT_CANCEL: Set this keyword to make the "Cancel" button the default
; selection for the dialog. The default selection is the button that is selected
; when the user presses the default keystroke (usually Space or Return depending
; on the platform). Setting DEFAULT_CANCEL implies that the CANCEL keyword is also
; set.
; DEFAULT_NO: Set this keyword to make the "No" button the default selection
; for "Question" dialogs. Normally, the default is "Yes".
; DIALOG_PARENT: Set this keyword to the widget ID of a widget over which
; the message dialog should be positioned. When displayed, the DIALOG_MESSAGE dialog
; will be positioned over the specified widget. Dialogs are often related to a
; non-dialog widget tree. The ID of the widget in that tree to which the dialog is most
; closely related should be specified.
; DISPLAY_NAME: Set this keyword equal to a string indicating the name of the
; X Windows display on which the dialog is to appear. This keyword is ignored if the
; DIALOG_PARENT keyword is specified. This keyword is also ignored on Microsoft Windows
; platforms.
; ERROR: Set this keyword to create an "Error" dialog. The default dialog type
; is "Warning".
; INFORMATION: Set this keyword to create an "Information" dialog. The default
; dialog type is "Warning".
; QUESTION: Set this keyword to create a "Question" dialog. The default dialog
; type is "Warning".
; RESOURCE_NAME: A string containing an X Window System resource name to be applied
; to the dialog. See RESOURCE_NAME for a complete discussion of this keyword.
; TITLE: Set this keyword to a scalar string that contains the text of a title to
; be displayed in the dialog frame. If this keyword is not specified, the dialog has the
; dialog type as its title as shown in the table under DIALOG_MESSAGE.
;
; NON IDL KEYWORDS
;
; ZENITY_NAME: Set this keyword to a scalar string used to overwrite Zenity
; executable name.
; ZENITY_PATH: If set, Zenith will be searched in this path. If it doesn't
; exist, then it will be searched in common unix paths. This can also be done
; by exporting the shell variable $ZENITY_PATH.
; HELP: Display a help message and return
; DEBUG: Display bebug messages
; VERBOSE: Switch on verbose mode
;
; OUTPUTS:
;
; OPTIONAL OUTPUTS:
;
; COMMON BLOCKS: none
;
; SIDE EFFECTS:
; - due to Zenity's capacities, the function ingnores
; the keyword parameters: DEFAULT_CANCEL, DEFAULT_NO,
; DIALOG_PARENT, CENTER
;
; RESTRICTIONS:
; - need Zenity v2.23.1 or higher to use filters
; (--ok-label=TEXTE and --cancel-label=TEXTE )
; - interface is not exactly the same ...
;
; PROCEDURE: straithforward
;
; EXAMPLE: resu_list=DIALOG_MESSAGE('hola')
; resu_list=DIALOG_MESSAGE('would you like to continue ?', /question)
;
; TESTABILITY: please test using interactive TEST_DIALOG_MESSAGE in testsuite/
; and add new test cases in this file
;
; MODIFICATION HISTORY:
;
; 23-Feb-2011: Implemented by Pedro Corona from DIALOG_PICKFILE written by Maxime Lenoir.
; 2-Mar-2011: Alain Coulais: Included the capability of manage more than one line of text
; older zenity Version management (no custom filters before v2.23.1)
; 15-Nov-2012: AC: complete revision, some codes exported into common ZENITY_CHECK()
; for better maintainability, better stick to orignal,
; using --list when need (old Zenity or/and /cancel)
; 05-Apr-2015: JP: Code for Windows platform is added.
;-
;
; This function try to reproduce the IDL's DIALOG_MESSAGE behavior using "zenity".
;
; zenity, under GNU GPL, is available in package on most Linux
; distributions (available and tested on CentOS 5.4, Mandriva 2010 and Ubuntu 9.04)
; Also on OSX: http://www.macports.org/ports.php?by=name&substr=zenity
;
; Since the implementation use Zenity as dialog messenger,
; some functionalities are different from the original one
; but this function works well for general purpose.
;
; Make sure that you have Zenity in your PATH
; You need to have Zenity v2.23.1 or higher to use filters and /Cancel renaming.
;
; Note: this code was tested, in conjonction with TEST_DIALOG_MESSAGE
; with Zenity 2.16, 2.24 and 2.30. Please report output of
; "zenity --version" and error code from TEST_DIALOG_MESSAGE if problem.
