Subject: add support for a <hide> property, which hides whole XML groups (widgets
X-Git-Url: https://git.mxchange.org/?a=commitdiff_plain;h=58179758af3a5a6e4875bdc40fd35c05481d2413;p=flightgear.git

add support for a <hide> property, which hides whole XML groups (widgets
or data blocks) from layouter and dialog creator. This is required for
dynamically generated/modified dialogs. Parts in the XML file can be
hidden and turned on by the C++ code. Other hidden parts can be used
as templates that are multiply used. Hidden datablocks can contain
strings that are used in dialog context, that are easier to translate
or modify in the XML file.
