Subject:   Inherit LoadFile and SaveFile from wxTextCtrlBase, reduce
X-Git-Url: https://git.saurik.com/wxWidgets.git/commitdiff_plain/ccb234b4d0b4f52ddb3100b55b53b32d1ea78d52

  Inherit LoadFile and SaveFile from wxTextCtrlBase, reduce
flicker caused by SetValue (the text itself still flickers a
bit, but now borders don't).


git-svn-id: https://svn.wxwidgets.org/svn/wx/wxWidgets/trunk@19885 c3d73ce0-8a6f-49c7-b76d-6d57e0e08775
