From fb1089e285a4f3d856e1307729b5981529137d63 Mon Sep 17 00:00:00 2001 From: jdgordon Date: Mon, 17 Sep 2007 10:08:50 +0000 Subject: [PATCH] minor update to gui_synclist_do_button() which will hopefully simplify things later. Now returns true if the action was handled in that function instead of returning the handled action. git-svn-id: svn://svn.rockbox.org/rockbox/trunk@14733 a1c6a512-1295-4272-9138-f99709370657 --- apps/bookmark.c | 2 +- apps/cuesheet.c | 2 +- apps/debug_menu.c | 2 +- apps/filetypes.c | 2 +- apps/gui/list.c | 44 ++++++++++++++++++----------- apps/gui/list.h | 13 +++------ apps/gui/option_select.c | 2 +- apps/menu.c | 2 +- apps/menus/settings_menu.c | 2 +- apps/playlist_catalog.c | 2 +- apps/playlist_viewer.c | 7 ++--- apps/plugin.h | 8 +++--- apps/plugins/chessbox/chessbox_pgn.c | 2 +- apps/plugins/lib/oldmenuapi.c | 2 +- apps/plugins/properties.c | 2 +- apps/plugins/random_folder_advance_config.c | 2 +- apps/plugins/shortcuts/shortcuts_view.c | 2 +- apps/plugins/text_editor.c | 2 +- apps/recorder/radio.c | 2 +- apps/screens.c | 4 +-- apps/tree.c | 14 ++++----- 21 files changed, 61 insertions(+), 59 deletions(-) diff --git a/apps/bookmark.c b/apps/bookmark.c index b2c271371..4522859f5 100644 --- a/apps/bookmark.c +++ b/apps/bookmark.c @@ -659,7 +659,7 @@ static char* select_bookmark(const char* bookmark_file_name, bool show_dont_resu } action = get_action(CONTEXT_BOOKMARKSCREEN, HZ / 2); - gui_synclist_do_button(&list, action, LIST_WRAP_UNLESS_HELD); + gui_synclist_do_button(&list, &action, LIST_WRAP_UNLESS_HELD); item = gui_synclist_get_sel_pos(&list) / 2; if (bookmarks->show_dont_resume) diff --git a/apps/cuesheet.c b/apps/cuesheet.c index 79a07a73c..d5fbc54f7 100644 --- a/apps/cuesheet.c +++ b/apps/cuesheet.c @@ -296,7 +296,7 @@ void browse_cuesheet(struct cuesheet *cue) { gui_synclist_draw(&lists); action = get_action(CONTEXT_LIST,TIMEOUT_BLOCK); - if (gui_synclist_do_button(&lists,action,LIST_WRAP_UNLESS_HELD)) + if (gui_synclist_do_button(&lists, &action, LIST_WRAP_UNLESS_HELD)) continue; switch (action) { diff --git a/apps/debug_menu.c b/apps/debug_menu.c index d5c0b8171..40c0fcc9b 100644 --- a/apps/debug_menu.c +++ b/apps/debug_menu.c @@ -162,7 +162,7 @@ static bool dbg_list(struct action_callback_info *info) { gui_syncstatusbar_draw(&statusbars, true); action = get_action(CONTEXT_STD, HZ/5); - if (gui_synclist_do_button(&lists, action, LIST_WRAP_UNLESS_HELD)) + if (gui_synclist_do_button(&lists, &action, LIST_WRAP_UNLESS_HELD)) continue; if (info->action_callback) action = info->action_callback(action, info); diff --git a/apps/filetypes.c b/apps/filetypes.c index 21ce17ce4..5e72fca5a 100644 --- a/apps/filetypes.c +++ b/apps/filetypes.c @@ -476,7 +476,7 @@ int filetype_list_viewers(const char* current_file) gui_syncstatusbar_draw(&statusbars, true); action = get_action(CONTEXT_MAINMENU,HZ); if ((action == ACTION_NONE) || - gui_synclist_do_button(&lists, action, LIST_WRAP_UNLESS_HELD)) + gui_synclist_do_button(&lists, &action, LIST_WRAP_UNLESS_HELD)) continue; else if (action == ACTION_STD_OK) { diff --git a/apps/gui/list.c b/apps/gui/list.c index f12d8a3d9..a8bbce8cd 100644 --- a/apps/gui/list.c +++ b/apps/gui/list.c @@ -889,9 +889,10 @@ static void gui_synclist_scroll_left(struct gui_synclist * lists) extern intptr_t get_action_data(void); -unsigned gui_synclist_do_button(struct gui_synclist * lists, - unsigned button,enum list_wrap wrap) +bool gui_synclist_do_button(struct gui_synclist * lists, + unsigned *actionptr, enum list_wrap wrap) { + int action = *actionptr; #ifdef HAVE_LCD_BITMAP static bool scrolling_left = false; #endif @@ -937,16 +938,16 @@ unsigned gui_synclist_do_button(struct gui_synclist * lists, gui_synclist_limit_scroll(lists, true); break; case LIST_WRAP_UNLESS_HELD: - if (button == ACTION_STD_PREVREPEAT || - button == ACTION_STD_NEXTREPEAT || - button == ACTION_LISTTREE_PGUP || - button == ACTION_LISTTREE_PGDOWN) + if (action == ACTION_STD_PREVREPEAT || + action == ACTION_STD_NEXTREPEAT || + action == ACTION_LISTTREE_PGUP || + action == ACTION_LISTTREE_PGDOWN) gui_synclist_limit_scroll(lists, true); else gui_synclist_limit_scroll(lists, false); break; }; - switch(button) + switch (action) { #ifdef HAVE_VOLUME_IN_LIST case ACTION_LIST_VOLUP: @@ -955,7 +956,7 @@ unsigned gui_synclist_do_button(struct gui_synclist * lists, case ACTION_LIST_VOLDOWN: global_settings.volume--; setvol(); - return button; + return true; #endif case ACTION_STD_PREV: case ACTION_STD_PREVREPEAT: @@ -968,7 +969,8 @@ unsigned gui_synclist_do_button(struct gui_synclist * lists, gui_synclist_draw(lists); } yield(); - return ACTION_STD_PREV; + *actionptr = ACTION_STD_PREV; + return true; case ACTION_STD_NEXT: case ACTION_STD_NEXTREPEAT: @@ -981,13 +983,14 @@ unsigned gui_synclist_do_button(struct gui_synclist * lists, gui_synclist_draw(lists); } yield(); - return ACTION_STD_NEXT; + *actionptr = ACTION_STD_NEXT; + return true; #ifdef HAVE_LCD_BITMAP case ACTION_TREE_PGRIGHT: gui_synclist_scroll_right(lists); gui_synclist_draw(lists); - return ACTION_TREE_PGRIGHT; + return true; case ACTION_TREE_ROOT_INIT: /* After this button press ACTION_TREE_PGLEFT is allowed to skip to root.
