First, a brief introduction to wxRenderer and why it is needed.
-
+
Usually wxWidgets uses the underlying low level GUI system to draw all the
- controls - this is what we mean when we say that it is a "native'' framework.
+ controls - this is what we mean when we say that it is a "native" framework.
However not all controls exist under all (or even any) platforms and in this
case wxWidgets provides a default, generic, implementation of them written in
wxWidgets itself.
-
+
These controls don't have the native appearance if only the standard
line drawing and other graphics primitives are used, because the native
appearance is different under different platforms while the lines are always
drawn in the same way.
-
+
This is why we have renderers: wxRenderer is a class which virtualizes the
drawing, i.e. it abstracts the drawing operations and allows you to draw say, a
button, without caring about exactly how this is done. Of course, as we
can draw the button differently in different renderers, this also allows us to
emulate the native look and feel.
-
+
So the renderers work by exposing a large set of high-level drawing functions
which are used by the generic controls. There is always a default global
- renderer but it may be changed or extended by the user, see
+ renderer but it may be changed or extended by the user, see
@ref overview_samplerender "Render sample".
-
+
All drawing functions take some standard parameters:
-
+
@e win is the window being drawn. It is normally not used and when
- it is it should only be used as a generic wxWindow
+ it is it should only be used as a generic wxWindow
(in order to get its low level handle, for example), but you should
not assume that it is of some given type as the same renderer
function may be reused for drawing different kinds of control.
@e rect the bounding rectangle for the element to be drawn.
@e flags the optional flags (none by default) which can be a
combination of the @c wxCONTROL_XXX constants below.
-
+
Note that each drawing function restores the wxDC attributes if
it changes them, so it is safe to assume that the same pen, brush and colours
that were active before the call to this function are still in effect after it.

The version has two components: the version itself and the age. If the main
program and the renderer have different versions they are never compatible with
each other because the version is only changed when an existing virtual
each time a new virtual method is added and so, at least for the compilers
using a common C++ object model, the calling program is compatible with any
renderer which has the age greater or equal to its age. This verification is
