Description

These functions manipulate the tree view widget in the main window.

Details

gva_tree_view_init ()

void                gva_tree_view_init                  (void);

Initializes the main tree view.

This function should be called once when the application starts.


gva_tree_view_lookup ()

GtkTreePath*        gva_tree_view_lookup                (const gchar *game);

Looks up game in the tree view's store and returns a GtkTreePath to the corresponding row, or NULL if game was not found.

game :

the name of a game

Returns :

a GtkTreePath to the row corresponding to game, or NULL

gva_tree_view_update ()

gboolean            gva_tree_view_update                (GError **error);

Refreshes the contents of the tree view by querying the game database using criteria appropriate for the currently selected game list view. If an error occurs, it returns FALSE and sets error.

error :

return location for a GError, or NULL

Returns :

TRUE on success, FALSE if an error occurred

gva_tree_view_run_query ()

gboolean            gva_tree_view_run_query             (const gchar *expression,
                                                         GError **error);

Similar to gva_tree_view_update() but applies custom criteria to the game database query. If an error occurs, it returns FALSE and sets error.

expression :

an SQL "where" expression

error :

return location for a GError, or NULL

Returns :

TRUE on success, FALSE if an error occurred

gva_tree_view_get_model ()

GtkTreeModel*       gva_tree_view_get_model             (void);

Thin wrapper for gtk_tree_view_get_model() that uses the main tree view.

Returns the model the main tree view is based on. Returns NULL if the model is unset.

Returns :

a GtkTreeModel, or NULL if the model is unset

gva_tree_view_update_status_bar ()

void                gva_tree_view_update_status_bar     (void);

Puts a message in the main status bar containing the MAME version and the number of games displayed in the current view. This message gets shown when the status bar has nothing more important to show.


gva_tree_view_get_selected_game ()

const gchar*        gva_tree_view_get_selected_game     (void);

Returns the name of the game corresponding to the currently selected row, or NULL if no row is selected.

Returns :

the name of the selected game, or NULL if no game is selected

gva_tree_view_set_selected_game ()

void                gva_tree_view_set_selected_game     (const gchar *game);

Selects the row corresponding to game. If the row is invisible in the current view, select the first row instead. The function also calls gva_tree_view_set_last_selected_game() so that the selected game will be persistent across sessions.

game :

the name of a game

gva_tree_view_get_selected_view ()

gint                gva_tree_view_get_selected_view     (void);

Returns the index of the currently selected view.

  • 0 = Available Games
  • 1 = Favorite Games
  • 2 = Search Results

Returns :

the index of the currently selected view

gva_tree_view_set_selected_view ()

void                gva_tree_view_set_selected_view     (gint view);

Sets the game list view corresponding to index view. See gva_tree_view_get_selected_view() for a list of valid indices.

Setting the game list view triggers a tree view update. See gva_tree_view_update() for details.

view :

index of the view to select

gva_tree_view_get_last_selected_game ()

const gchar*        gva_tree_view_get_last_selected_game
                                                        (void);

Returns the name of the most recently selected game in either the current or the previous session of GNOME Video Arcade. Note that it is still possible for this function to return NULL.

Returns :

the name of the most recently selected game

gva_tree_view_set_last_selected_game ()

void                gva_tree_view_set_last_selected_game
                                                        (const gchar *game);

Writes game to GConf key /apps/gnome-video-arcade/selected-game.

This is used to remember which game was selected in the previous session of GNOME Video Arcade so that the same game can be selected again automatically at startup.

game :

the name of a game

gva_tree_view_get_last_sort_column_id ()

void                gva_tree_view_get_last_sort_column_id
                                                        (GvaGameStoreColumn *column_id,
                                                         GtkSortType *order);

Retrieves the most recently selected sort column ID and sort order in either the current or the previous session of GNOME Video Arcade.

column_id :

return location for the column ID

order :

return location for the sort order

gva_tree_view_set_last_sort_column_id ()

void                gva_tree_view_set_last_sort_column_id
                                                        (GvaGameStoreColumn column_id,

Writes column_id and order to GConf key /apps/gnome-video-arcade/sort-column.

This is used to remember which how the game list view was sorted in the previous session of GNOME Video Arcade so that the same sorting can be applied again automatically at startup.

column_id :

sort column ID

order :

sort order
