Detailed Description
Contexts are used for registering actions with Core::ActionManager, and when creating UI elements that provide a context for actions.
See The Action Manager and Commands for an overview of how contexts are used.
See also Core::IContext, Core::ActionManager, and The Action Manager and Commands.
Member Type Documentation
[alias] Context::const_iterator
The Context::const_iterator provides an STL-style const interator for Context.
Member Function Documentation
[constexpr noexcept] Context::Context()
Creates a context list that represents the global context.
[explicit] Context::Context(Utils::Id c1)
Creates a context list with a single ID c1.
Context::Context(Utils::Id c1, Utils::Id c2)
Creates a context list with IDs c1 and c2.
Context::Context(Utils::Id c1, Utils::Id c2, Utils::Id c3)
Creates a context list with IDs c1, c2 and c3.
void Context::add(const Core::Context &c)
Adds the context list c at the end of this context list.
void Context::add(Utils::Id c)
Adds the ID c at the end of the context list.
Utils::Id Context::at(int i) const
Returns the ID at index i in the context list.
Core::Context::const_iterator Context::begin() const
Returns an STL-style iterator pointing to the first ID in the context list.
bool Context::contains(Utils::Id c) const
Returns whether this context list contains the ID c.
Core::Context::const_iterator Context::end() const
Returns an STL-style iterator pointing to the imaginary item after the last ID in the context list.
int Context::indexOf(Utils::Id c) const
Returns the index position of the ID c in the context list. Returns -1 if no item matched.
bool Context::isEmpty() const
Returns whether this context list is empty and therefore default constructed.
void Context::prepend(Utils::Id c)
Adds the ID c as the first item to the context list.
void Context::removeAt(int i)
Removes the ID at index i from the context list.
int Context::size() const
Returns the number of IDs in the context list.
