In wxPropertyGridPage class derived from wxPropertyGridPageState and wxPropertyGridInterface, function GetPropertyByLabel is inherited from both base classes. To resolve this ambiguity, function defined in wxPGInterface is introduced in wxPGPage through 'using-declaration'. (This is a temporary fix and finally GetPropertyByLabel function should be removed from wxPropertyGridPageState.) See #15251. git-svn-id: https://svn.wxwidgets.org/svn/wx/wxWidgets/trunk@76925 c3d73ce0-8a6f-49c7-b76d-6d57e0e08775
