115 /* There are two naming schemes involved and we want to have a mapping between
116 them. There are Win32 clipboard format names and there are Mac pasteboard
117 types.
118
119 The Win32 standard clipboard formats don't have names, but they are associated
120 with Mac pasteboard types through the following tables, which are used to
121 initialize the format_list. Where possible, the standard clipboard formats
122 are mapped to predefined pasteboard type UTIs. Otherwise, we create Wine-
123 specific types of the form "org.winehq.builtin.<format>", where <format> is
124 the name of the symbolic constant for the format minus "CF_" and lowercased.
125 E.g. CF_BITMAP -> org.winehq.builtin.bitmap.
126
127 Win32 clipboard formats which originate in a Windows program may be registered
128 with an arbitrary name. We construct a Mac pasteboard type from these by
129 prepending "org.winehq.registered." to the registered name.
130
131 Likewise, Mac pasteboard types which originate in other apps may have
132 arbitrary type strings. We ignore these.
133
134 Summary:
135 Win32 clipboard format names:
136 <none> standard clipboard format; maps via
137 format_list to either a predefined Mac UTI
138 or org.winehq.builtin.<format>.
139 <other> name registered within Win32 land; maps to
140 org.winehq.registered.<other>
141 Mac pasteboard type names:
142 org.winehq.builtin.<format ID> representation of Win32 standard clipboard
143 format for which there was no corresponding
144 predefined Mac UTI; maps via format_list
145 org.winehq.registered.<format name> representation of Win32 registered
146 clipboard format name; maps to <format name>
147 <other> Mac pasteboard type originating with system
148 or other apps; either maps via format_list
149 to a standard clipboard format or ignored

1765 type for each of those IDs (e.g. CF_TEXT -> "org.winehq.builtin.text") and then see
1766 if that type is present in the pasteboard. If it is, then we don't want to add the
1767 format to the list yet because it would be out of order.
1768
1769 For example, if a Mac app put "public.utf8-plain-text" and "public.tiff" on the
1770 pasteboard, then we want the Win32 clipboard formats to be CF_TEXT, CF_OEMTEXT, and
1771 CF_UNICODETEXT, and CF_TIFF, in that order. All of the text formats belong before
1772 CF_TIFF because the Mac app expressed that text was "better" than the TIFF. In
1773 this case, as soon as we encounter "public.utf8-plain-text" we should add all of
1774 the associated text format IDs.
1775
1776 But if a Wine process put "org.winehq.builtin.unicodetext",
1777 "public.utf8-plain-text", "public.utf16-plain-text", and "public.tiff", then we
1778 want the clipboard formats to be CF_UNICODETEXT, CF_TIFF, CF_TEXT, and CF_OEMTEXT,
1779 in that order. The Windows program presumably added CF_UNICODETEXT and CF_TIFF.
1780 We're synthesizing CF_TEXT and CF_OEMTEXT from CF_UNICODETEXT but we want them to
1781 come after the non-synthesized CF_TIFF. In this case, we don't want to add the
1782 text formats upon encountering "public.utf8-plain-text",
1783
1784 We tell the two cases apart by seeing that one of the natural types for the text
1785 formats (i.e. "org.winehq.builtin.unicodetext") is present on the pasteboard.
1786 "found" indicates that. */
