gtkWindowSetFocus {RGtk2} | R Documentation

## gtkWindowSetFocus

### Description

If `focus` is not the current focus widget, and is focusable, sets it as the focus widget for the window. If `focus` is `NULL`, unsets the focus widget for this window. To set the focus to a particular widget in the toplevel, it is usually more convenient to use `gtkWidgetGrabFocus` instead of this function.

### Usage

    gtkWindowSetFocus(object, focus = NULL)

### Arguments

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