/* There are two naming schemes involved and we want to have a mapping between
|
|
them. There are Win32 clipboard format names and there are Mac pasteboard
|
|
types.
|
|
|
|
The Win32 standard clipboard formats don't have names, but they are associated
|
|
with Mac pasteboard types through the following tables, which are used to
|
|
initialize the format_list. Where possible, the standard clipboard formats
|
|
are mapped to predefined pasteboard type UTIs. Otherwise, we create Wine-
|
|
specific types of the form "org.winehq.builtin.<format>", where <format> is
|
|
the name of the symbolic constant for the format minus "CF_" and lowercased.
|
|
E.g. CF_BITMAP -> org.winehq.builtin.bitmap.
|
|
|
|
Win32 clipboard formats which originate in a Windows program may be registered
|
|
with an arbitrary name. We construct a Mac pasteboard type from these by
|
|
prepending "org.winehq.registered." to the registered name.
|
|
|
|
Likewise, Mac pasteboard types which originate in other apps may have
|
|
arbitrary type strings. We ignore these.
|
|
|
|
Summary:
|
|
Win32 clipboard format names:
|
|
<none> standard clipboard format; maps via
|
|
format_list to either a predefined Mac UTI
|
|
or org.winehq.builtin.<format>.
|
|
<other> name registered within Win32 land; maps to
|
|
org.winehq.registered.<other>
|
|
Mac pasteboard type names:
|
|
org.winehq.builtin.<format ID> representation of Win32 standard clipboard
|
|
format for which there was no corresponding
|
|
predefined Mac UTI; maps via format_list
|
|
org.winehq.registered.<format name> representation of Win32 registered
|
|
clipboard format name; maps to <format name>
|
|
<other> Mac pasteboard type originating with system
|
|
or other apps; either maps via format_list
|
|
to a standard clipboard format or ignored
