Remove unnecessary, never used methods. Don't use pointers when objects or references can be used more safely. Don't name classes which are not part of wx with "wx" prefix to avoid confusing people. Don't define empty unnecessary event tables. Prefer wxScrolledWindow::SetVirtualSize() to SetScrollbars(). Stop using "protected" when "private" should be used. git-svn-id: https://svn.wxwidgets.org/svn/wx/wxWidgets/trunk@64300 c3d73ce0-8a6f-49c7-b76d-6d57e0e08775

/*
|
|
This sample show document/view support in wxWidgets.
|
|
|
|
It can be run in several ways:
|
|
* With "--mdi" command line option to use multiple MDI child frames
|
|
for the multiple documents (this is the default).
|
|
* With "--sdi" command line option to use multiple top level windows
|
|
for the multiple documents
|
|
* With "--single" command line option to support opening a single
|
|
document only
|
|
|
|
Notice that doing it like this somewhat complicates the code, you could
|
|
make things much simpler in your own programs by using either
|
|
wxDocParentFrame or wxDocMDIParentFrame unconditionally (and never using
|
|
the single mode) instead of supporting all of them as this sample does.
