◆ 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.

Definition at line 981 of file HydrogenApp.cpp.

◆ 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, update the GUI to represent the new song. If 1, a message in the status bar will be displayed notifying the user about the saving of the current Song. If 2, notifies the user that the current song is opened in read-only mode.

Reimplemented from EventListener.
