Implemented Interfaces
RBDisplayPageModel implements GtkTreeModel, GtkTreeDragSource, RbTreeDragSource and RbTreeDragDest.
Description
The RBDisplayPageTree widget is backed by a GtkTreeStore containing the sources and a set of attributes used to structure and display them, and a GtkTreeModelFilter that hides sources with the visibility property set to FALSE. This class implements the filter model and also creates the actual model.
The display page model supports drag and drop in a variety of formats. The simplest of these are text/uri-list and application/x-rhythmbox-entry, which convey URIs and IDs of existing database entries. When dragged to an existing source, these just add the URIs or entries to the target source. When dragged to an empty space in the tree widget, this results in the creation of a static playlist.
text/x-rhythmbox-artist, text/x-rhythmbox-album, and text/x-rhythmbox-genre are used when dragging items from the library browser. When dragged to the display page tree, these result in the creation of a new auto playlist with the dragged items as criteria.
Functions
rb_display_page_model_new ()
RBDisplayPageModel *
rb_display_page_model_new (void
);
This constructs both the GtkTreeStore holding the display page data and the filter model that hides invisible pages.
rb_display_page_model_set_playing_source ()
void rb_display_page_model_set_playing_source (RBDisplayPageModel *page_model
,RBDisplayPage *source
);
Updates the model with the new playing source.
rb_display_page_model_add_page ()
void rb_display_page_model_add_page (RBDisplayPageModel *page_model
,RBDisplayPage *page
,RBDisplayPage *parent
);
Adds a page to the model, either below a specified page (if it's a source or something else) or at the top level (if it's a group)
rb_display_page_model_remove_page ()
void rb_display_page_model_remove_page (RBDisplayPageModel *page_model
,RBDisplayPage *page
);
Removes a page from the model.
rb_display_page_model_find_page ()
gboolean rb_display_page_model_find_page (RBDisplayPageModel *page_model
,RBDisplayPage *page
,GtkTreeIter *iter
);
Finds a GtkTreeIter for a specified page in the model. This will only find pages that are currently visible. The returned GtkTreeIter can be used with the RBDisplayPageModel.
rb_display_page_model_set_dnd_targets ()
void rb_display_page_model_set_dnd_targets (RBDisplayPageModel *page_model
,GtkTreeView *treeview
);
Sets up the drag and drop targets for the display page tree.
Types and Values
enum RBDisplayPageModelColumn
Columns present in the display page model.
struct RBDisplayPageModelClass
struct RBDisplayPageModelClass { GtkTreeModelFilterClass parent_class; void (*drop_received) (RBDisplayPageModel *model, RBDisplayPage *target, GtkTreeViewDropPosition pos, GtkSelectionData *data); void (*page_inserted) (RBDisplayPageModel *model, RBDisplayPage *page, GtkTreeIter *iter); };
Signal Details
The “drop-received”
signal
void user_function (RBDisplayPageModel *model, RBDisplayPage *target, gint pos, gpointer data, gpointer user_data)
Emitted when a drag and drop operation to the display page tree completes.
Parameters
model |
||
target |
the RBSource receiving the drop |
|
pos |
the drop position |
|
data |
the drop data |
|
user_data |
user data set when the signal handler was connected. |
Flags: Run Last
The “page-inserted”
signal
void user_function (RBDisplayPageModel *model, RBDisplayPage *page, GtkTreeIter *iter, gpointer user_data)
Emitted when a new page is inserted into the model. Use this instead of GtkTreeModel::row-inserted as this doesn't get complicated by visibility filtering.
Parameters
model |
||
page |
the RBDisplayPage that was inserted |
|
iter |
a GtkTreeIter indicating the page position |
|
user_data |
user data set when the signal handler was connected. |
Flags: Run Last
