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. + + + + + A global interface used for exporting surfaces that can later be imported + using xdg_importer. + + + + + Notify the compositor that the xdg_exporter object will no longer be + used. + + + + + + The export request exports the passed surface so that it can later be + imported via xdg_importer. When called, a new xdg_exported object will + be created and xdg_exported.handle will be sent immediately. See the + corresponding interface and event for details. + + A surface may be exported multiple times, and each exported handle may + be used to create a xdg_imported multiple times. Only xdg_surface + surfaces may be exported. + + + + + + + + + A global interface used for importing surfaces exported by xdg_exporter. + With this interface, a client can create a reference to a surface of + another client. + + + + + Notify the compositor that the xdg_importer object will no longer be + used. + + + + + + The import request imports a surface from any client given a handle + retrieved by exporting said surface using xdg_exporter.export. When + called, a new xdg_imported object will be created. This new object + represents the imported surface, and the importing client can + manipulate its relationship using it. See xdg_imported for details. + + + + + + + + + A xdg_exported object represents an exported reference to a surface. The + exported surface may be referenced as long as the xdg_exported object not + destroyed. Destroying the xdg_exported invalidates any relationship the + importer may have established using xdg_imported. + + + + + Revoke the previously exported surface. This invalidates any + relationship the importer may have set up using the xdg_imported created + given the handle sent via xdg_exported.handle. + + + + + + The handle event contains the unique handle of this exported surface + reference. It may be shared with any client, which then can use it to + import the surface by calling xdg_importer.import. A handle may be + used to import the surface multiple times. + + + + + + + + A xdg_imported object represents an imported reference to surface exported + by some client. A client can use this interface to manipulate + relationships between its own surfaces and the imported surface. + + + + + Notify the compositor that it will no longer use the xdg_imported + object. Any relationship that may have been set up will at this point + be invalidated. + + + + + + Set the imported surface as the parent of some surface of the client. + The passed surface must be a toplevel xdg_surface. Calling this function + sets up a surface to surface relation with the same stacking and positioning + semantics as xdg_surface.set_parent. + + + + + + + The imported surface handle has been destroyed and any relationship set + up has been invalidated. This may happen for various reasons, for + example if the exported surface or the exported surface handle has been + destroyed, if the handle used for importing was invalid. + + + + + -- cgit v1.2.1
