Prerequisites

XfwWorkspaceGroup requires GObject.

Description

Workspaces may be arranged in groups, and groups may be present on different monitors. The XfwWorkspaceGroup can create and enumerate workspaces, as well as provide notifications when workspaces are created and destroyed.

Each workspace group may have an active workspace.

Workspace groups are displayed on a list of zero or more monitors, and have viewport coordinates.

Note that XfwWorkspaceGroup 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_group_get_capabilities ()

XfwWorkspaceGroupCapabilities
xfw_workspace_group_get_capabilities (XfwWorkspaceGroup *group);

group

an XfwWorkspaceGroup.

Returns

an XfwWorkspaceGroupCapabilities bitfield.

xfw_workspace_group_create_workspace ()

gboolean
xfw_workspace_group_create_workspace (XfwWorkspaceGroup *group,

                                      GError **error);

Attempts to create a new workspace on group . Typically, the new workspace will be appended to the existing list of workspaces.

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

Parameters

group	an XfwWorkspaceGroup.
name	a name for the new workspace.
error	a location to store a possible error.	[out callee-allocates]

Returns

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

Moves the workspace group to a new location, and possibly a new monitor.

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

Parameters

group	an XfwWorkspaceGroup.
x	a coordinate in the horizontal direction.
y	a coordinate in the vertical direction.
error	a location to store a possible error.	[out callee-allocates]

Returns

TRUE if moving the workspace group 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_group_set_layout ()

gboolean

                                gint rows,
                                gint columns,
                                GError **error);

Sets the layout of group to rows by columns .

Note that this will not change the number of workspaces if the new layout implies a larger number of workspaces than currently exists.

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

Parameters

group	an XfwWorkspaceGroup.
rows	the new numbers of rows.
columns	the new number of columns.
error	a location to store a possible error.	[out callee-allocates]

Returns

TRUE if changing the layout of group succeede, FALSE otherwise. If FALSE, and error is non-NULL, an error will be returned that must be freed using g_error_free().
