## Prerequisites

GtkOrientable requires GObject.

## Known Implementations

GtkOrientable is implemented by GtkAppChooserWidget, GtkBox, GtkButtonBox, GtkCellAreaBox, GtkCellRendererProgress, GtkCellView, GtkColorChooserWidget, GtkColorSelection, GtkFileChooserButton, GtkFileChooserWidget, GtkFontChooserWidget, GtkFontSelection, GtkGrid, GtkHBox, GtkHButtonBox, GtkHPaned, GtkHScale, GtkHScrollbar, GtkHSeparator, GtkInfoBar, GtkLevelBar, GtkPaned, GtkProgressBar, GtkRange, GtkRecentChooserWidget, GtkScale, GtkScaleButton, GtkScrollbar, GtkSeparator, GtkSpinButton, GtkStackSwitcher, GtkStatusbar, GtkToolPalette, GtkToolbar, GtkVBox, GtkVButtonBox, GtkVPaned, GtkVScale, GtkVScrollbar, GtkVSeparator and GtkVolumeButton.

## Properties

      "orientation"              GtkOrientation        : Read / Write

## Description

The GtkOrientable interface is implemented by all widgets that can be oriented horizontally or vertically. Historically, such widgets have been realized as subclasses of a common base class (e.g GtkBox/GtkHBox/GtkVBox or GtkScale/GtkHScale/GtkVScale). GtkOrientable is more flexible in that it allows the orientation to be changed at runtime, allowing the widgets to 'flip'.

GtkOrientable was introduced in GTK+ 2.16.

## Details

### GtkOrientable

    typedef struct _GtkOrientable GtkOrientable;

### gtk_orientable_get_orientation ()

    GtkOrientation      gtk_orientable_get_orientation      (GtkOrientable *orientable);

Retrieves the orientation of the `orientable`.

`orientable` : | a GtkOrientable
Returns : | the orientation of the `orientable`.

Since 2.16

### gtk_orientable_set_orientation ()

    void                gtk_orientable_set_orientation      (GtkOrientable *orientable,
                                                             GtkOrientation orientation);

Sets the orientation of the `orientable`.

`orientable` : | a GtkOrientable
`orientation` : | the orientable's new orientation.

Since 2.16

## Property Details

### The `"orientation"` property

      "orientation"              GtkOrientation        : Read / Write

The orientation of the orientable.

Default value: GTK_ORIENTATION_HORIZONTAL

Since 2.16
