Interfaces

Detailed Description

GtkMessageDialog presents a dialog with an image representing the type of message (Error, Question, etc.) alongside some message text. It's simply a convenience widget; you could construct the equivalent of GtkMessageDialog from GtkDialog without too much effort, but GtkMessageDialog saves typing. The easiest way to do a modal message dialog is to use gtkDialogRun, though you can also pass in the GTK_DIALOG_MODAL flag, gtkDialogRun automatically makes the dialog modal and waits for the user to respond to it. gtkDialogRun returns when any dialog button is clicked. A modal dialog. 
# A Modal dialog
dialog <- gtkMessageDialog(main_application_window, "destroy-with-parent",
                           "error", "close", "Error loading file '", filename,
                           "': ", message)
dialog$run()
dialog$destroy()
You might do a non-modal GtkMessageDialog as follows: A non-modal dialog. 
dialog <- gtkMessageDialog(main_application_window, "destroy-with-parent",
                           "error", "close", "Error loading file '", filename,
                           "': ", message)
# Destroy the dialog when the user responds to it (e.g. clicks a button)
gSignalConnect(dialog, "response", gtkWidgetDestroy)

Structures

Convenient Construction

gtkMessageDialog is the result of collapsing the constructors of GtkMessageDialog (gtkMessageDialogNew, gtkMessageDialogNewWithMarkup) and accepts a subset of its arguments matching the required arguments of one of its delegate constructors.

GtkMessageType
The type of message being displayed in the dialog.
info
Informational message
warning
Nonfatal warning message
question

GtkButtonsType
Prebuilt sets of buttons for the dialog. If none of these choices are appropriate, simply use GTK_BUTTONS_NONE then call gtkDialogAddButtons.
none
no buttons at all
ok
an OK button

a Close button
cancel
