From 3368d37a980f5f31182fca5c22e175f444ccae9f Mon Sep 17 00:00:00 2001 From: John Stebbins Date: Mon, 11 Jun 2018 15:15:01 -0700 Subject: LinGui: add search function to language popups The language list is long and displays native names while sorted by English names, so it is difficult to find a language. This adds the ability to "search" for a language based on it's initial character. Typing a character will jump to the next entry that starts with that character in its native name. --- gtk/src/callbacks.c | 45 +++++++++++++++++++++++++++++++++++++++++++++ gtk/src/hb-backend.c | 3 +++ 2 files changed, 48 insertions(+) (limited to 'gtk') diff --git a/gtk/src/callbacks.c b/gtk/src/callbacks.c index 94e3f8b2c..a1091c0cd 100644 --- a/gtk/src/callbacks.c +++ b/gtk/src/callbacks.c @@ -5885,3 +5885,48 @@ void ghb_container_empty(GtkContainer *c) { gtk_container_foreach(c, container_empty_cb, NULL); } + +G_MODULE_EXPORT gboolean +combo_search_key_press_cb( + GtkWidget *widget, + GdkEvent *event, + signal_user_data_t *ud) +{ + GtkComboBox * combo = GTK_COMBO_BOX(widget); + GtkTreeModel * model = GTK_TREE_MODEL(gtk_combo_box_get_model(combo)); + GtkTreeIter iter, prev_iter; + gchar * lang; + guint keyval; + gunichar key_char; + gunichar first_char; + int pos = 0, count = 2048; + + ghb_event_get_keyval(event, &keyval); + key_char = g_unichar_toupper(gdk_keyval_to_unicode(keyval)); + if (gtk_combo_box_get_active_iter(combo, &iter)) + { + while (pos <= count) + { + pos++; + prev_iter = iter; + if (!gtk_tree_model_iter_next(model, &iter)) + { + GtkTreePath * path = gtk_tree_model_get_path(model, &prev_iter); + gint * ind = gtk_tree_path_get_indices(path);; + + count = ind[0]; + gtk_tree_path_free(path); + gtk_tree_model_get_iter_first(model, &iter); + } + gtk_tree_model_get(model, &iter, 0, &lang, -1); + first_char = g_unichar_toupper(g_utf8_get_char(lang)); + g_free(lang); + if (first_char == key_char) + { + gtk_combo_box_set_active_iter(combo, &iter); + break; + } + } + } + return FALSE; +} diff --git a/gtk/src/hb-backend.c b/gtk/src/hb-backend.c index 3d947c8c1..433e21bfc 100644 --- a/gtk/src/hb-backend.c +++ b/gtk/src/hb-backend.c @@ -2016,6 +2016,8 @@ srt_codeset_opts_set(signal_user_data_t *ud, const gchar *name, } } +extern G_MODULE_EXPORT void combo_search_key_press_cb(void); + static void language_opts_set(signal_user_data_t *ud, const gchar *name, void *opts, const void* data) @@ -2048,6 +2050,7 @@ language_opts_set(signal_user_data_t *ud, const gchar *name, 3, (gdouble)ii, -1); } + g_signal_connect(combo, "key-press-event", combo_search_key_press_cb, ud); } gchar* -- cgit v1.2.3
