Member Function Documentation

virtual bool hotkey::hotkey_void::bindings_equal_helper ( hotkey_ptr  other) const
inlineprotectedvirtual

This is invoked by hotkey_base::bindings_equal as a helper for the concrete classes.

Implementing classes should only check their parts of the hotkey.

Parameters
otherThe other hotkey the check against. Not guaranteed to be the same subclass.
Returns
true if they match, false otherwise.

Implements hotkey::hotkey_base.

Definition at line 298 of file hotkey_item.hpp.

virtual const std::string hotkey::hotkey_void::get_name_helper ( ) const
inlineprotectedvirtual

This is invoked by hotkey_base::get_name and must be implemented by subclasses.

Keyboard modifiers are handled in this class, other hotkeys in the respective classes

Implements hotkey::hotkey_base.

Definition at line 290 of file hotkey_item.hpp.

virtual bool hotkey::hotkey_void::matches_helper ( const SDL_Event &  event) const
inlineprotectedvirtual

This is invoked by hotkey_base::matches as a helper for the concrete classes.

Implementing classes should only check their parts of the hotkey.

Parameters
eventThe SDL_Event being generated.
Returns
true if they match, false otherwise.

Implements hotkey::hotkey_base.
