NB: there used to be some code here which set the initial size of the

|
|
that they get a WM_SIZE (EVT_SIZE) upon creation, however this broke
|
|
it. To see why, you should understand that Windows sends WM_SIZE from
|
|
inside ::CreateWindow() anyhow. However, ::CreateWindow() is called
|
|
from some base class ctor and so this WM_SIZE is not processed in the
|
|
real class' OnSize() (because it's not fully constructed yet and the
|
|
event goes to some base class OnSize() instead). So the WM_SIZE we
|
|
rely on is the one sent when the parent frame resizes its children
|
|
but here is the problem: if the child already has just the right
|
|
size, nothing will happen as both wxWindows and Windows check for
|
|
this and ignore any attempts to change the window size to the size it
|
|
already has - so no WM_SIZE would be sent.
