C++ Option::getDefaultIndex方法代码示例

//! The (overloaded) initializeControl routine is responsible for the following
//! tasks:
//!  - Ensuring the control displays the appropriate options based on the
//!    contents of the OptionDatabase.
//!  - Adding the ToolTip documentation found in the database.
//!  - Adding connections (signals & slots) between the Nodes in the
//!    OptionRegister and the control.  This allows for synchronization of the
//!    logic in InitializeQChemLogic and initializeQuiLogic.
//!  - Binding an Action to enable the control to be reset to the default value.
//!  - Binding an Update to enable the control to be reset to a string value.
