# wxDCClipper Class Reference
[Graphics Device Interface (GDI)]

`#include </home/work/projects/wx/2.9/wx/interface/wx/dc.h>`

## Detailed Description

wxDCClipper is a small helper class for setting a clipping region on a wxDC and unsetting it automatically.

An object of wxDCClipper class is typically created on the stack so that it is automatically destroyed when the object goes out of scope. A typical usage example:

        void MyFunction(wxDC& dc)
        {
            wxDCClipper clip(dc, rect);
            // ... drawing functions here are affected by clipping rect ...
        }

        void OtherFunction()
        {
            wxDC dc;
            MyFunction(dc);
            // ... drawing functions here are not affected by clipping rect ...
        }
