wxHtmlWindow::SetSize not working under wxWidgets-3.0.0

[Marco DeFreitas]

I create a wxHtmlWindow and load in a html page. I then try to set the size
of the wxHtmlWindow to the actual rendered size with
wxHtmlWindow::GetInternalRepresentation::GetWidth and
wxHtmlWindow::GetInternalRepresentation::GetHeight. The GetWidth/GetHeight
functions seem to return the correct values, but the SetSize seems to have
no effect. The size originally set in the wxHtmlWindow constructor remains.

This can be duplicated in the html/about sample program. Just change the
original height that the wxHtmlWindow is created in the constructor to 700.
You can then see that the about dialog box gets created with a height of
700 (and not adjusted to the internal rendered size as it should).

This worked under wxWidgets-2.8.12.

This problem seems to appear on both wxGTK and wxMSW.

Thanks,
Marco

This doesn't have anything to do with wxHtmlWindow actually and is just
due to the change in the way the sizers work: they now consider the initial
size of the window to be its minimal size and not its current size, i.e.
the size set in the ctor or by SetInitialSize() and not the size last set
by SetSize().

IOW you need to use SetInitialSize() here. Or explicitly use
wxSizer::SetItemMinSize(), which might be more clear.

Using SetInitialSize works great, thanks.

You might want to change the html/about sample program to use
SetInitialSize, so people using that as a guide would use the correct
function.

Thanks again!

I had already done it.
