C++ Mixer::id方法代码示例

/**
 * Create or recreate the Mixer GUI elements

 * @param forceNewTab To enforce opening a new tab, even when the profileList in the kmixrc is empty.
 *                    It should only be set to "true" in case of a Hotplug (because then the user definitely expects a new Tab to show).
