gtkPreviewSetExpand {RGtk2} | R Documentation

## gtkPreviewSetExpand

### Description

Determines the way that the the preview widget behaves when the size it is allocated is larger than the requested size. If `expand` is `FALSE`, then the preview's window and buffer will be no larger than the size set with `gtkPreviewSize`, and the data set will be centered in the allocation if it is larger. If `expand` is `TRUE` then the window and buffer will expand with the allocation; the application is responsible for catching the "size_allocate" signal and providing the data appropriate for this size. WARNING: `gtk_preview_set_expand` is deprecated and should not be used in newly-written code.

### Usage

    gtkPreviewSetExpand(object, expand)

### Arguments

``object`` | a `GtkPreview`.
``expand`` | whether the preview's window should expand or not.
