This is a "patch" for the Video Disk Recorder (VDR). * Authors: Tobias Grimm <vdr at e-tobi dot net> Martin Prochnow <nordlicht at martins-kabuff dot de> Frank Schmirler <vdrdev at schmirler dot de> Christian Wieninger <cwieninger at gmx dot de> * Description: This patch allows plugins to replace the VDR mainmenus "Schedule", "Channels", "Timers" and "Recordings" by a different implementation. The patch is based on a suggestion of Christian Wieninger back in 2006. (http://www.linuxtv.org/pipermail/vdr/2006-March/008234.html). It is meant to be an interim solution for VDR 1.4 until (maybe) VDR 1.5 introduces an official API for this purpose. * Installation Change into the VDR source directory, then issue patch -p1 < path/to/MainMenuHooks-v1_0.patch and recompile. * Notes for plugin authors The following code sample shows the required plugin code for replacing the original Schedule menu: bool cMyPlugin::Service(const char *Id, void *Data) { cOsdMenu **menu = (cOsdMenu**) Data; if (MySetup.replaceSchedule && strcmp(Id, "MainMenuHooksPatch-v1.0::osSchedule") == 0) { if (menu) *menu = (cOsdMenu*) MainMenuAction(); return true; } return false; } A plugin can replace more than one menu at a time. Simply replace the call to MainMenuAction() in the sample above by appropriate code). Note that a plugin *should* offer a setup option which allows the user to enable or disable the replacement. "Disabled" would be a reasonable default setting. By testing for define MAINMENUHOOKSVERSNUM, a plugin can leave the setup option out at compiletime. In case there is an internal problem when trying to open the replacement menu, it is safe to return true even though Data is NULL. However an OSD message should indicate the problem to the user. Feel free to ship this patch along with your plugin. However if you think you need to modify the patch, we'd encourage you to contact the authors first or at least use a service id which differs in more than just the version number. diff -p -up vdr-1.6.0/config.h.orig vdr-1.6.0/config.h --- vdr-1.6.0/config.h.orig 2009-07-25 21:22:30.742094984 +0300 +++ vdr-1.6.0/config.h 2009-07-25 21:22:31.430095065 +0300 @@ -42,6 +42,8 @@ #define LIEMIKUUTIO 127 +#define MAINMENUHOOKSVERSNUM 1.0 + #define MAXPRIORITY 99 #define MAXLIFETIME 99 diff -p -up vdr-1.6.0/menu.c.orig vdr-1.6.0/menu.c --- vdr-1.6.0/menu.c.orig 2009-07-25 21:22:31.282094446 +0300 +++ vdr-1.6.0/menu.c 2009-07-25 21:22:31.434092890 +0300 @@ -3234,15 +3234,30 @@ cMenuMain::cMenuMain(eOSState State) // Initial submenus: + cOsdMenu *menu = NULL; switch (State) { - case osSchedule: AddSubMenu(new cMenuSchedule); break; - case osChannels: AddSubMenu(new cMenuChannels); break; - case osTimers: AddSubMenu(new cMenuTimers); break; - case osRecordings: AddSubMenu(new cMenuRecordings(NULL, 0, true)); break; - case osSetup: AddSubMenu(new cMenuSetup); break; - case osCommands: AddSubMenu(new cMenuCommands(tr("Commands"), &Commands)); break; + case osSchedule: + if (!cPluginManager::CallFirstService("MainMenuHooksPatch-v1.0::osSchedule", &menu)) + menu = new cMenuSchedule; + break; + case osChannels: + if (!cPluginManager::CallFirstService("MainMenuHooksPatch-v1.0::osChannels", &menu)) + menu = new cMenuChannels; + break; + case osTimers: + if (!cPluginManager::CallFirstService("MainMenuHooksPatch-v1.0::osTimers", &menu)) + menu = new cMenuTimers; + break; + case osRecordings: + if (!cPluginManager::CallFirstService("MainMenuHooksPatch-v1.0::osRecordings", &menu)) + menu = new cMenuRecordings(NULL, 0, true); + break; + case osSetup: menu = new cMenuSetup; break; + case osCommands: menu = new cMenuCommands(tr("Commands"), &Commands); break; default: break; } + if (menu) + AddSubMenu(menu); } cOsdObject *cMenuMain::PluginOsdObject(void) @@ -3385,13 +3400,34 @@ eOSState cMenuMain::ProcessKey(eKeys Key eOSState state = cOsdMenu::ProcessKey(Key); HadSubMenu |= HasSubMenu(); + cOsdMenu *menu = NULL; switch (state) { - case osSchedule: return AddSubMenu(new cMenuSchedule); - case osChannels: return AddSubMenu(new cMenuChannels); - case osTimers: return AddSubMenu(new cMenuTimers); - case osRecordings: return AddSubMenu(new cMenuRecordings); - case osSetup: return AddSubMenu(new cMenuSetup); - case osCommands: return AddSubMenu(new cMenuCommands(tr("Commands"), &Commands)); + case osSchedule: + if (!cPluginManager::CallFirstService("MainMenuHooksPatch-v1.0::osSchedule", &menu)) + menu = new cMenuSchedule; + else + state = osContinue; + break; + case osChannels: + if (!cPluginManager::CallFirstService("MainMenuHooksPatch-v1.0::osChannels", &menu)) + menu = new cMenuChannels; + else + state = osContinue; + break; + case osTimers: + if (!cPluginManager::CallFirstService("MainMenuHooksPatch-v1.0::osTimers", &menu)) + menu = new cMenuTimers; + else + state = osContinue; + break; + case osRecordings: + if (!cPluginManager::CallFirstService("MainMenuHooksPatch-v1.0::osRecordings", &menu)) + menu = new cMenuRecordings; + else + state = osContinue; + break; + case osSetup: menu = new cMenuSetup; break; + case osCommands: menu = new cMenuCommands(tr("Commands"), &Commands); break; case osStopRecord: if (Interface->Confirm(tr("Stop recording?"))) { cOsdItem *item = Get(Current()); if (item) { @@ -3478,6 +3514,8 @@ eOSState cMenuMain::ProcessKey(eKeys Key default: break; } } + if (menu) + return AddSubMenu(menu); if (!HasSubMenu() && Update(HadSubMenu)) Display(); if (Key != kNone) {
