↑ V730 Not all members of a class are initialized inside the constructor. Consider inspecting: m_focusOnIdle.

↑ V524 It is odd that the body of 'PrependColumn' function is fully equivalent to the body of 'AppendColumn' function.
↑ V818 It is more efficient to use an initialization list 'm_value(value)' rather than an assignment operator.
↑ V813 Decreased performance. The 'rectCell' argument should probably be rendered as a constant reference.

↑ V809 Verifying that a pointer value is not NULL is not required. The 'if (m_data)' check can be removed.
↑ V820 The 'temp' variable is not used after copying. Copying can be replaced with move/swap for optimization.
↑ V807 Decreased performance. Consider creating a reference to avoid using the 'node->GetChildren()' expression repeatedly.
↑ V820 The 'value2' variable is not used after copying. Copying can be replaced with move/swap for optimization.
↑ V820 The 'value1' variable is not used after copying. Copying can be replaced with move/swap for optimization.
↑ V821 Decreased performance. The 'changeFont' variable can be constructed in a lower level scope.
