Pebble: How to override the back button when you are using a menu layer
/* Add those lines somewhere in your file */
// Define what you want to do when the back button is pressed
void back_button_handler(ClickRecognizerRef recognizer, void *context) {
APP_LOG(APP_LOG_LEVEL_DEBUG, "back clicked");
}
// We need to save a reference to the ClickConfigProvider originally set by the menu layer
ClickConfigProvider previous_ccp;
// This is the new ClickConfigProvider we will set, it just calls the old one and then subscribe
// for back button events.
void new_ccp(void *context) {
APP_LOG(APP_LOG_LEVEL_DEBUG, "calling the new ccp");
previous_ccp(context);
window_single_click_subscribe(BUTTON_ID_BACK, back_button_handler);
APP_LOG(APP_LOG_LEVEL_DEBUG, "done in the new ccp");
}
// Call this from your init function to do the hack
void force_back_button(Window *window, MenuLayer *menu_layer) {
previous_ccp = window_get_click_config_provider(window);
window_set_click_config_provider_with_context(window, new_ccp, menu_layer);
}
/* ... */
void init() {
/* ... */
menu_layer_set_click_config_onto_window(menu_layer, window);
force_back_button(window, menu_layer);
/* ... */
