KisChangeValueCommand< mem_ptr, ValueType > Struct Template Reference

#include <KisChangeValueCommand.h>

Detailed Description

template<auto mem_ptr, typename ValueType>
struct KisChangeValueCommand< mem_ptr, ValueType >

A simple command that flips the state of a member variable in a contained structure.

For example, to change the variable m_d->fooBar to the value newValue in an undoable fashion, just create a command like that:

   \code{.cpp}

   KUndo2Command *cmd =
       makeChangeValueCommand<&Private::fooBar>(m_d.data(), newValue);

   \endcode

It is not strictly necessary that newValue had the same type as the type of the member variable. They may differ, given the types are convertible.
