The data browser is both an entity that monitors of various data in Gwyddion and the corresponding user interface showing the data lists and letting the user deleting or copying them. The public functions are generally related to the first part.
An GwyContainer that represents an SPM file is managed by functions such as gwy_app_data_browser_add() or
gwy_app_data_browser_remove(). Note that the high-level libgwyapp functions (with app in their name) such as
gwy_app_file_load() already call the data browser functions as appropriate.
If a file-like GwyContainer has not been added to the data browser it is unmanaged and cannot be used with most of
the data browser functions. The exceptions are GQuark constructors such as gwy_app_get_mask_key_for_id(), copying
functions such as gwy_app_data_browser_copy_channel(), title management functions such as
gwy_app_set_surface_title(), thumbnail creation helpers such as gwy_app_get_graph_thumbnail(), and functions for
listing the ids of various data types such as gwy_app_data_browser_get_data_ids().
Individual data pieces can be added to managed GwyContainers with functions such as
gwy_app_data_browser_add_data_field() that can take care of creating the window showing the new data. Removal is
generally done by directly removing the corresponding data object(s) from the GwyContainer.
An important part of the data browser is keeping track which data item is currently selected (to know what a data
processing method should process, etc.). You can obtain the information about various currently selected objects
using gwy_app_data_browser_get_current(). Making a data item currently selected is accomplished either using
function such as gwy_app_data_browser_select_data_view(), which corresponds to the user switching to the data
window, or gwy_app_data_browser_select_data_field() which just selects the data item as current in the browser.
The latter is less safe and can result in strange behaviour because for some purposes only data actually displayed
can be ‘current’.

Since: 2.21
void
gwy_app_data_browser_add (GwyContainer *data);
Adds a data container to the application data browser.
The data browser takes a reference on the container so you can release yours.
data |

void
gwy_app_data_browser_remove (GwyContainer *data);
Removed a data container from the application data browser.
data |
A data container. |
void

A data container, not managed by the data browser. |
Since: 2.7
GwyContainer *
gwy_app_data_browser_get (gint number);
Gets the data corresponding to a numerical identifier.
The identifier can be obtained with gwy_app_data_browser_get_number(). See its documentation for discussion.
number |
Numerical identifier of open data managed by the data browser, or zero. |
The corresponding data container. NULL is returned if number
does not identify any existing data.
Since: 2.41
gint
gwy_app_data_browser_get_number (GwyContainer *data);
Gets the numerical identifier of data.
Each time a data container is added with gwy_app_data_browser_add() it is assigned a new unique numerical
identifier. This number can be used in multi-data modules to remember and restore secondary data.
Note, however, that the number is only guaranteed to be unique within one process. It does not persist across different program invocations and it does not make sense to store it to the settings or other kinds of permanent storage.
data |
A data container managed by the data browser. For convenience, |
A positive numerical identifier of data
. Zero is returned if data
is NULL.
Since: 2.41
gboolean gwy_app_data_browser_reset_visibility (GwyContainer *data,GwyVisibilityResetType reset_type);
Resets visibility of all data objects in a container.
data |

|
reset_type |
Type of visibility reset. |
TRUE if anything is visible after the reset.
void
gwy_app_data_browser_set_keep_invisible
(GwyContainer *data,
gboolean keep_invisible);
Sets data browser behaviour for inaccessible data.
Normally, when all visual objects belonging to a file are closed the container is removed from the data browser and
dereferenced, leading to its finalization. By setting keep_invisible
to TRUE the container can be made to sit in
the browser indefinitely.
data |

See gwy_app_data_browser_set_keep_invisible().
void
gwy_app_data_browser_block_switching (void);
Temporarily blocks data switching according to the active window.
This may be necessary during operations which would be derailed by data switching. For instance DnD from tree views showing the contents of active data does not work correctly if the window manager switches active windows during the DnD, so at the drop time the tree view content no longer matches the dragged row.
Use gwy_app_data_browser_unblock_switching() to restore data switching. It will also switch data to the window that
should be currently active, if the active window has changed (but without any intermediate steps if the active
window has changed multiple times).
Switching cannot be blocked permanently because it would get the data browser out of sync.
Since: 2.67
void
gwy_app_data_browser_unblock_switching
(void);
Stops temporarily blocking data switching according to the active window.
The blocking is started by gwy_app_data_browser_block_switching(). See its description for details.

void gwy_app_data_browser_get_current (GwyAppWhat what,...);
Gets information about current objects.
All output arguments are always set to some value, even if the requested object does not exist. Object arguments
are set to pointer to the object if it exists (no reference is added), or cleared to NULL if no such object
exists.
Quark arguments are set to the corresponding key even if no such object is actually present (use object arguments to check for object presence) but the location where it would be stored is known. This is common with presentations and masks. They are be set to 0 if no corresponding location exists -- for example, when the current mask key is requested but the current data contains no channel (or there is no current data at all).
The rules for id arguments are similar to quarks, except they are set to -1 to indicate undefined result.
The current objects can change due to user interaction even during the execution of modal dialogs (typically used by modules). Therefore to achieve consistency one has to ask for the complete set of current objects at once.

gboolean

Reports whether creation of windows by the data-browser is enabled.
TRUE if the data-browser is permitted to create windows, FALSE if it is not.
Since: 2.21
void
gwy_app_data_browser_set_gui_enabled (gboolean setting);
Globally enables or disables creation of widgets by the data-browser.
By default, the data-browser creates windows for data objects automatically, for instance when reconstructing view
of a loaded file, after a module function creates a new channel or graph or when it is explicitly asked so by
gwy_app_data_browser_show_3d(). Non-GUI applications that run module functions usually wish to disable GUI.
If GUI is disabled the data browser never creates windows showing data objects and also gwy_app_data_browser_show()
becomes no-op.
Disabling GUI after widgets have been already created is a bad idea. Hence you should do so before loading files or calling module functions.
