gtkWindowSetDefault {RGtk2} | R Documentation

## gtkWindowSetDefault

### Description

The default widget is the widget that's activated when the user presses Enter in a dialog (for example). This function sets or unsets the default widget for a `GtkWindow` about. When setting (rather than unsetting) the default widget it's generally easier to call `gtkWidgetGrabFocus` on the widget. Before making a widget the default widget, you must set the `GTK_CAN_DEFAULT` flag on the widget you'd like to make the default using `gtkWidgetSetFlags()`.

### Usage

    gtkWindowSetDefault(object, default.widget = NULL)

### Arguments

``object`` | a `GtkWindow`
``default.widget`` | widget to be the default, or `NULL` to unset the default widget for the toplevel. [ allow-none ]
