\section{\class{wxDCClipper}}\label{wxdcclipper}
|

|
|
|
||
|
|
wxDCClipper is a small helper class for setting a clipping region on a
|
||
|
|
\helpref{wxDC}{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:
|
||
|
|
|
||
|
|
\begin{verbatim}
|
||
|
|
void MyFunction(wxDC& dc)
|
||
|
|
{
|
||
|
|
wxDCClipper clip(rect);
|
||
|
|
... drawing functions here are affected by clipping rect ...
|
||
|
|
}
|
||
|
|
|
||
|
|
void OtherFunction()
|
||
|
|
{
|
||
|
|
wxDC dc;
|
||
|
|
MyFunction(dc);
|
||
|
|
... drawing functions here are not affected by clipping rect ...
|
||
|
|
}
|
||
|
|
\end{verbatim}

|

|
||
|
|
\func{}{wxDCClipper}{\param{wxDC\& }{dc}, \param{const wxRegion\& }{r}}
|
||
|
|
|
||
|
|
\func{}{wxDCClipper}{\param{wxDC\& }{dc}, \param{const wxRect\& }{rect}}
|
||
|
|
|
||
|
|
\func{}{wxDCClipper}{\param{wxDC\& }{dc}, \param{int }{x}, \param{int }{y}, \param{int }{w}, \param{int }{h}}
|
||
|
|
|
||
|
|
Sets the clipping region to the specified region \arg{r} or rectangle specified
|
||
|
|
by either a single \arg{rect} parameter or its position (\arg{x} and \arg{y})
|
||
|
|
and size (\arg{w} ad \arg{h}).
|
||
|
|
|
||
|
|
The clipping region is automatically unset when this object is destroyed.
