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.

Member Function Documentation

[constexpr noexcept] Context::Context()

Creates a context list that represents the global context.

[explicit] Context::Context(int c1)

Creates a context list with a single ID c1.

Context::Context(int c1, int c2)

Creates a context list with IDs c1 and c2.

Context::Context(int c1, int c2, int 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.

int Context::at(int) const

Returns the ID at index i in the context list.

int Context::begin() const

Returns an STL-style iterator pointing to the first ID in the context list.

int Context::end() const

Returns an STL-style iterator pointing to the imaginary item after the last ID in the context list.

bool Context::isEmpty() const
