Function called every QUEUE_TIMER_PERIOD millisecond to pop all Events from the EventQueue and invoke the corresponding functions.

Depending on the H2Core::EventType, the following members of EventListener will be called:

In addition, all MIDI notes in H2Core::EventQueue::m_addMidiNoteVector will converted into actions via SE_addNoteAction() and deleted from the former array.

sFilename Absolute path used to load the next Song.

Returns: bool true on success

◆ openSong() [2/2]

bool openSong ( H2Core::Song * pSong )

◆ quitEvent()

void quitEvent ( int nValue )

overrideprivatevirtual

Calls closeAll() to shutdown Hydrogen.

Parameters

nValue unused

Reimplemented from EventListener.

◆ updateMixerCheckbox()

void updateMixerCheckbox ( )

◆ updatePreferencesEvent()

void updatePreferencesEvent ( int nValue )

overrideprivatevirtual

Handles the loading and saving of the H2Core::Preferences from the core part of H2Core::Hydrogen.

If nValue is 0 - the H2Core::Preferences got saved - it triggers the display of a message in the status bar. If, on the other hand, nValue is 1 and the configuration file has been reloaded, it gets a fresh version of H2Core::Preferences and updates all widgets and setting to reflect the changes in the configuration.

Parameters

nValue If 0, Preferences was save. If 1, it was loaded.

Reimplemented from EventListener.

◆ updateSongEvent()

void updateSongEvent ( int nValue )

overrideprivatevirtual

Refreshes and updates the GUI after the Song was changed in the core part of Hydrogen.

When using session management or changing the Song using an OSC message, this command will get core and GUI in sync again.

Parameters

nValue If 0 or 1, loads the Song stored in H2Core::Hydrogen::m_pNextSong. If 1, also restarts the audio driver via H2Core::Hydrogen::restartDrivers(). If 2, a message in the status bar will be displayed notifying the user about the saving of the current Song to the config file.

Reimplemented from EventListener.
