## Prerequisites

XfwWorkspace requires GObject.

## Includes

    #include <libxfce4windowing/libxfce4windowing.h>

## Description

XfwWorkspace represents a single workspace within a workspace group. A workspace is usually a collection of windows that are shown together on the desktop when that workspace is the active workspace.

An instance of XfwWorkspace can be used to obtain information about the workspace, such as its name, position in the group, and capabilities. The workspace can also be activated or removed.

Note that XfwWorkspace is actually an interface; when obtaining an instance, an instance of a windowing-environment-specific object that implements this interface will be returned.

## Functions

### xfw_workspace_get_id ()

    const gchar *
    xfw_workspace_get_id (XfwWorkspace *workspace);

Fetches this workspace's opaque ID.

#### Parameters

workspace | an XfwWorkspace. |

#### Returns

A UTF-8 formatted string, owned by `workspace` .

[not nullable][transfer none]

### xfw_workspace_get_name ()

    const gchar *
    xfw_workspace_get_name (XfwWorkspace *workspace);

Fetches this workspace's human-readable name.

#### Parameters

workspace | an XfwWorkspace. |

#### Returns

A UTF-8 formatted string, owned by `workspace` .

[not nullable][transfer none]

### xfw_workspace_get_capabilities ()

    XfwWorkspaceCapabilities
    xfw_workspace_get_capabilities (XfwWorkspace *workspace);

Fetches this workspace's capabilities bitfield.

The bitfield describes what operations are available on this workspace.

#### Parameters

workspace | an XfwWorkspace. |

#### Returns

a XfwWorkspaceCapabilities bitfield.

### xfw_workspace_get_state ()

    XfwWorkspaceState
    xfw_workspace_get_state (XfwWorkspace *workspace);

Fetches this workspace's state bitfield.

#### Parameters

workspace | an XfwWorkspace. |

#### Returns

a XfwWorkspaceState bitfield.

### xfw_workspace_get_number ()

    guint
    xfw_workspace_get_number (XfwWorkspace *workspace);

Fetches the ordinal number of this workspace.

The number can be used to order workspaces in a UI representation.

On X11, this number should be stable across runs of your application.

On Wayland, this number depends on the order in which the compositor advertises the workspaces. This order may be stable, but may not be.

#### Parameters

workspace | an XfwWorkspace. |

#### Returns

a non-negative, 0-indexed integer.

### xfw_workspace_get_workspace_group ()

    XfwWorkspaceGroup *
    xfw_workspace_get_workspace_group (XfwWorkspace *workspace);

Fetches the group this workspace belongs to, if any.

#### Parameters

workspace | an XfwWorkspace. |

#### Returns

a XfwWorkspaceGroup instance, owned by `workspace` , or `NULL` if the workspace is not a member of any groups.

[nullable][transfer none]

### xfw_workspace_get_layout_row ()

    gint
    xfw_workspace_get_layout_row (XfwWorkspace *workspace);

Fetches the row this workspace belongs to in the workspace's group.

This information can be used to lay out workspaces in a grid in a pager UI, for example.

#### Parameters

workspace | an XfwWorkspace. |

#### Returns

a non-negative, 0-indexed integer.

### xfw_workspace_get_layout_column ()

    gint
    xfw_workspace_get_layout_column (XfwWorkspace *workspace);

Fetches the column this workspace belongs to in the workspace's group.

This information can be used to lay out workspaces in a grid in a pager UI, for example.

#### Parameters

workspace | an XfwWorkspace. |

#### Returns

a non-negative, 0-indexed integer.

### xfw_workspace_get_neighbor ()

    XfwWorkspace *
    xfw_workspace_get_neighbor (XfwWorkspace *workspace,
                                XfwDirection direction);

Fetches the workspace that resides in `direction` from the `workspace` , if any. If workspace is on the edge of the layout, and `direction` points off the edge of the layout, will return `NULL`.

#### Parameters

workspace | an XfwWorkspace. |
direction | an XfwDirection. |

#### Returns

a XfwWorkspace, owned by the parent `group` , or `NULL` if no workspace exists in `direction` .

[nullable][transfer none]

### xfw_workspace_get_geometry ()

    GdkRectangle *
    xfw_workspace_get_geometry (XfwWorkspace *workspace);

Fetches the position and size of the workspace in screen coordinates.

The values in the returned GdkRectangle are owned by `workspace` and should not be modified.

#### Parameters

workspace | an XfwWorkspace. |

#### Returns

a GdkRectangle, owned by `workspace` .

[not nullable][transfer none]

                            GError **error);

On failure, `error` (if provided) will be set to a description of the error that occurred.

#### Parameters

workspace | an XfwWorkspace. |
error | a location to store a possible error. | [out callee-allocates]

#### Returns

`TRUE` if workspace activation succeeded, `FALSE` otherwise. If `FALSE`, and `error` is non-`NULL`, an error will be returned that must be freed using ``g_error_free()``.

### xfw_workspace_remove ()

    gboolean
    xfw_workspace_remove (XfwWorkspace *workspace,
                          GError **error);

Attempts to remove `workspace` from its group.

On failure, `error` (if provided) will be set to a description of the error that occurred.

#### Parameters

workspace | an XfwWorkspace. |
error | a location to store a possible error. | [out callee-allocates]

#### Returns

`TRUE` if workspace removal succeeded, `FALSE` otherwise. If `FALSE`, and `error` is non-`NULL`, an error will be returned that must be freed using ``g_error_free()``.

### xfw_workspace_assign_to_workspace_group ()

    gboolean
    xfw_workspace_assign_to_workspace_group
                                   (XfwWorkspace *workspace,
                                    XfwWorkspaceGroup *group,
                                    GError **error);

error | a location to store a possible error. | [out callee-allocates]

#### Returns

`TRUE` if workspace assignment succeeded, `FALSE` otherwise. If `FALSE`, and `error` is non-`NULL`, an error will be returned that must be freed using `g_error_free()`.
