Detailed Description

Core API for accessing core playback DSP settings as well as spawning DSP configuration dialogs.
Use static_api_ptr_t<dsp_config_manager>() to instantiate.

Member Function Documentation

virtual HWND dsp_config_manager::configure_embedded ( const dsp_chain_config &  p_initdata, HWND  p_parent, unsigned  p_id, bool  p_from_modal  )

pure virtual

Spawns an embedded DSP settings dialog.

Parameters

p_initdata	Initial DSP chain configuration to put in the dialog.
p_parent	Parent window to contain the embedded dialog.
p_id	Control ID of the embedded dialog. The parent window will receive a WM_COMMAND with BN_CLICKED and this identifier when user changes settings in the embedded dialog.
p_from_modal	Must be set to true when the parent window is a modal dialog, false otherwise.

virtual void dsp_config_manager::configure_embedded_change ( HWND  wnd, const dsp_chain_config &  p_data  )

pure virtual

Changes current settings in an embedded DSP settings dialog. See also: configure_embedded().

virtual void dsp_config_manager::configure_embedded_retrieve ( HWND  wnd, dsp_chain_config &  p_data  )

pure virtual

Retrieves current settings from an embedded DSP settings dialog. See also: configure_embedded().

virtual bool dsp_config_manager::configure_popup ( dsp_chain_config &  p_data, HWND  p_parent, const char *  p_title  )

pure virtual

Runs a modal DSP settings dialog.

Parameters

p_data

DSP chain configuration to edit - contains initial configuration to put in the dialog when called, receives the new configuration on successful edit.

Returns

True when user approved DSP configuration changes (pressed the "OK" button), false when the user cancelled them ("Cancel" button).

void dsp_config_manager::core_disable_dsp

(

const GUID &

id

)

Helper - disables a DSP in core playback settings.

void dsp_config_manager::core_enable_dsp

(

const dsp_preset &

preset

)

Helper - enables a DSP in core playback settings.

    if (changed) set_core_settings(cfg);
}

bool dsp_config_manager::core_query_dsp	(	const GUID &	id,
		dsp_preset &	out
	)

Helper - if a DSP with the specified identifier is present in playback settings, retrieves its configuration and returns true, otherwise returns false.
