gtkDialog(title = NULL, parent = NULL, flags = 0, ..., show = TRUE)GtkBuildable.GtkVBox, and is where widgets such as a GtkLabel or a GtkEntry should
be packed. The bottom area is known as the
action_area. This is generally used for
packing buttons into the dialog which may perform functions such as
cancel, ok, or apply. The two areas are separated by a GtkHSeparator.
GtkDialog boxes are created with a call to gtkDialogNew or
gtkDialogNewWithButtons. gtkDialogNewWithButtons is recommended; it
allows you to set the dialog title, some convenient flags, and add simple
buttons.
If 'dialog' is a newly created dialog, the two primary areas of the window
can be accessed through gtkDialogGetContentArea and
gtkDialogGetActionArea, as can be seen from the example, below.
A 'modal' dialog (that is, one which freezes the rest of the application from
user input), can be created by calling gtkWindowSetModal on the dialog. Use
the gtkWindow() function to cast the widget returned from gtkDialogNew into a
GtkWindow. When using gtkDialogNewWithButtons you can also pass the
GtkDialog using gtkDialogNewWithButtons,
gtkDialogAddButton, gtkDialogAddButtons, or
gtkDialogAddActionWidget, clicking the button will emit a signal called
"response" with a response ID that you specified. GTK+ will never assign a
meaning to positive response IDs; these are entirely user-defined. But for
convenience, you can use the response IDs in the GtkResponseType enumeration
(these all have values less than zero). If a dialog receives a delete event,
the "response" signal will be emitted with a response ID of gtkDialogRun. This function enters a
recursive main loop and waits for the user to respond to the dialog, returning the
response ID corresponding to the button the user clicked.
For the simple dialog in the following example, in reality you'd probably use
GtkMessageDialog to save yourself some effort. But you'd need to create the
dialog contents manually if you had more than a simple message in the dialog. Simple GtkDialog usage.
# Function to open a dialog box displaying the message provided.
quick_message <- function(message) {
## Create the widgets
dialog <- gtkDialog("Message", NULL, "destroy-with-parent",
"gtk-ok", GtkResponseType["none"],
show = FALSE)
label <- gtkLabel(message)
## Ensure that the dialog box is destroyed when the user responds.
gSignalConnect(dialog, "response", gtkWidgetDestroy)
## Add the label, and show everything we've added to the dialog.
dialog[["vbox"]]$add(label) dialog$showAll() }
vbox and action.area as internal children with the names "vbox" and
"action_area".
GtkDialog supports a custom action.area).
A GtkDialog UI definition fragment.gtkDialog is the result of collapsing the constructors of GtkDialog (gtkDialogNew, gtkDialogNewWithButtons) and accepts a subset of its arguments matching the required arguments of one of its delegate constructors.
