NAME

6       wxClientDC - Functions for wxClientDC class

DESCRIPTION

9       wxClientDC is primarily useful for obtaining information about the win‐
10       dow from outside EVT_PAINT() handler.
11
12       Typical use of this class is to obtain the extent of some  text  string
13       in order to allocate enough size for a window, e.g.
14
15       Note:  While wxClientDC may also be used for drawing on the client area
16       of a window from outside an EVT_PAINT() handler  in  some  ports,  this
17       does not work on all platforms (neither wxOSX nor wxGTK with GTK 3 Way‐
18       land backend support this, so drawing using wxClientDC  simply  doesn't
19       have  any effect there) and the only portable way of drawing is via wx‐
20       PaintDC. To redraw  a  small  part  of  the  window,  use  wxWindow:re‐
21       freshRect/3  to  invalidate  just  this  part and check wxWindow:getUp‐
22       dateRegion/1 in the paint event handler to redraw this part only.
23
24       wxClientDC objects should normally be constructed  as  temporary  stack
25       objects, i.e. don't store a wxClientDC object.
26
27       A  wxClientDC object is initialized to use the same font and colours as
28       the window it is associated with.
