With such a reference, a client can, by using the + interfaces provided by this protocol, manipulate the relationship between + its own surfaces and the surface of some other client. For example, stack + some of its own surface above the other clients surface. + + In order for a client A to get a reference of a surface of client B, client + B must first export its surface using xdg_exporter.export. Upon doing this, + client B will receive a handle (a unique string) that it may share with + client A in some way (for example D-Bus). After client A has received the + handle from client B, it may use xdg_importer.import to create a reference + to the surface client B just exported. See the corresponding requests for + details. + + A possible use case for this is out-of-process dialogs. For example when a + sandboxed client without file system access needs the user to select a file + on the file system, given sandbox environment support, it can export its + surface, passing the exported surface handle to an unsandboxed process that + can show a file browser dialog and stack it above the sandboxed client's + surface. + + Warning! The protocol described in this file is experimental and backward + incompatible changes may be made. Backward compatible changes may be added + together with the corresponding interface version bump. Backward + incompatible changes are done by bumping the version number in the protocol + and interface names and resetting the interface version. Once the protocol + is to be declared stable, the 'z' prefix and the version number in the + protocol and interface names are removed and the interface version number is + reset. + </description> + + <interface name="zxdg_exporter_v1" version="1"> + <description summary="interface for exporting surfaces"> + A global interface used for exporting surfaces that can later be imported + using xdg_importer. + </description> + + <request name="destroy" type="destructor"> + <description summary="destroy the xdg_exporter object"> + Notify the compositor that the xdg_exporter object will no longer be + used. + </description> + </request> + + <request name="export"> + <description summary="export a surface"> + The export request exports the passed surface so that it can later be + imported via xdg_importer.
