These functions manipulate the main window, excluding the tree view. The tree view functions are documented separately in the
gva-tree-viewsection.
void
gva_main_init (void
);
Initializes the main window.
This function should be called once when the application starts.
gboolean
gva_main_build_database (GError **error
);
Executes the lengthy process of constructing the games database. The function updates the main window's progress bar to help track the database construction. The function is synchronous; it blocks until database construction is complete or aborted.
gboolean
gva_main_analyze_roms (GError **error
);
Executes the lengthy process of analyzing all available ROM and sample sets for correctness and then updating the games database with the new status information. The function updates the main window's progress bar to help track the analysis. The function is synchronous; it blocks until the analysis is complete or aborted.
gboolean
gva_main_init_search_completion (GError **error
);
Initializes autocompletion in the search entry. This must be done
after the game database is built and ROMs are
analyzed. If an error occurs, the function returns FALSE
and sets
error
.
void gva_main_connect_proxy_cb (GtkUIManager *manager
,GtkAction *action
,GtkWidget *proxy
);
Callback for manager
's "connect
-proxy" signal. The function configures
main menu items to display the appropriate tooltip in the status bar when
the mouse hovers over them. action
supplies the tooltip.
void
gva_main_cursor_busy (void
);
Sets the mouse cursor to busy. Generally useful before starting a long-running foreground task.
void
gva_main_cursor_normal (void
);
Sets the mouse cursor back to normal. Generally useful after completing a long-running foreground task.
void
gva_main_progress_bar_show (void
);
Shows the progress bar in the main window's status bar and sets the mouse cursor to busy. Generally useful before starting a long-running foreground task.
void
gva_main_progress_bar_hide (void
);
Hides the progress bar in the main window's status bar and sets the mouse cursor back to normal. Generally useful after completing a long-running foreground task.
void
gva_main_progress_bar_set_fraction (gdouble fraction
);
Thin wrapper for gtk_progress_bar_set_fraction()
that uses the main
window's progress bar.
Causes the progress bar to "fill in" the given fraction of the bar. The fraction should be between 0.0 and 1.0, inclusive.
guint
gva_main_statusbar_get_context_id (const gchar *context_description
);
Thin wrapper for gtk_statusbar_get_context_id()
that uses the main
window's status bar.
Returns a new context identifier, given a description of the actual context. Note that the description is not shown in the UI.
guint gva_main_statusbar_push (guint context_id
,const gchar *format
,...
);
Thin wrapper for gtk_statusbar_push()
that uses the main window's
status bar.
Pushes a new message onto the status bar's stack. As a convenience,
the function takes a
-style format string
and variable length argument list.printf()
void
gva_main_statusbar_pop (guint context_id
);
Thin wrapper for gtk_statusbar_pop()
that uses the main window's
status bar.
Removes the first message in the status bar's stack with the given context id.
Note that this may not change the displayed message, if the message at the top of the stack has a different context id.
void gva_main_statusbar_remove (guint context_id
,guint message_id
);
Thin wrapper for gtk_statusbar_remove()
that uses the main window's
status bar.
Forces the removal of a message from a status bar's stack. The exact
context_id
and message_id
must be specified.
void
gva_main_clear_search (void
);
Clears the search entry and, if the Search Results view is active, any results from the previous search.
void
gva_main_execute_search (void
);
Executes a game database search and configures the main window to display the results. More precisely, the function saves the search entry contents to GSettings, switches to the Search Results view, forces an update, ensures a row in the resulting game list is selected, and gives focus to the main tree view.
The SQL expression used in the database search is retrieved from
gva_main_get_search_expression()
. It is applied while updating the
Search Results view.
gchar *
gva_main_get_last_search_text (void
);
Returns the most recent search entry text from either the current or previous session of GNOME Video Arcade.
void
gva_main_set_last_search_text (const gchar *text
);
Writes text
to GSettings key search
.
This is used to remember the search entry text from the previous session of GNOME Video Arcade so that the same text can be preset in the search entry at startup.
gboolean gva_main_get_last_selected_match (gchar **column_name
,gchar **search_text
);
Returns the most recently selected match in a search completion list
from either the current or previous session of GNOME Video
Arcade. If the completion feature was not used in the
most recent search, column_name
and search_text
are set to NULL
and the function returns FALSE
.
void gva_main_set_last_selected_match (const gchar *column_name
,const gchar *search_text
);
Writes column_name
and search_text
to GSettings key
sql-expression
as a string tuple.
This is used to remember whether the search results from the previous session of GNOME Video Arcade were the result of selecting a match from the search completion list. If so, the values are also used to restore the contents of the Search Results view.
void
gva_main_search_entry_activate_cb (GtkEntry *entry
);
Handler for “activate” signals to the search entry.
Saves the contents of the search entry and switches the main window to the "Search Results" view.
void
gva_main_search_entry_changed_cb (GtkEntry *entry
);
Handler for “changed” signals to the search entry.
Updates the sensitivity of the clear search icon.
void gva_main_search_entry_icon_release_cb (GtkEntry *entry
,GtkEntryIconPosition position
,GdkEvent *event
);
Handler for “icon-release” signals to the search entry.
If position
is GTK_ENTRY_ICON_SECONDARY
, clears the search entry.
void gva_main_search_entry_notify_cb (GtkEntry *entry
,GParamSpec *pspec
);
Handler for “notify” signals to the search entry.
Hides the search interface when the search entry loses input focus.
gboolean gva_main_search_query_tooltip_cb (GtkWidget *widget
,gint x
,gint y
,gboolean keyboard_mode
,GtkTooltip *tooltip
);
Handler for “query-tooltip” signals to the search interface.
Displays some tips for searching.

gboolean gva_main_window_configure_event_cb (GtkWindow *window
,GdkEventConfigure *event
);

Saves the main window state to dconf.
gboolean gva_main_window_window_state_event_cb (GtkWindow *window
,GdkEventWindowState *event
);
