This primary selection is a shortcut to the + common clipboard selection, where text just needs to be selected in order + to allow copying it elsewhere. The de facto way to perform this action + is the middle mouse button, although it is not limited to this one. + + Clients wishing to honor primary selection should create a primary + selection source and set it as the selection through + wp_primary_selection_device.set_selection whenever the text selection + changes. In order to minimize calls in pointer-driven text selection, + it should happen only once after the operation finished. Similarly, + a NULL source should be set when text is unselected. + + wp_primary_selection_offer objects are first announced through the + wp_primary_selection_device.data_offer event. Immediately after this event, + the primary data offer will emit wp_primary_selection_offer.offer events + to let know of the mime types being offered. + + When the primary selection changes, the client with the keyboard focus + will receive wp_primary_selection_device.selection events. Only the client + with the keyboard focus will receive such events with a non-NULL + wp_primary_selection_offer. Across keyboard focus changes, previously + focused clients will receive wp_primary_selection_device.events with a + NULL wp_primary_selection_offer. + + In order to request the primary selection data, the client must pass + a recent serial pertaining to the press event that is triggering the + operation, if the compositor deems the serial valid and recent, the + wp_primary_selection_source.send event will happen in the other end + to let the transfer begin. The client owning the primary selection + should write the requested data, and close the file descriptor + immediately. + + If the primary selection owner client disappeared during the transfer, + the client reading the data will receive a + wp_primary_selection_device.selection event with a NULL + wp_primary_selection_offer, the client should take this as a hint + to finish the reads related to the no longer existing offer. + + The primary selection owner should be checking for errors during + writes, merely cancelling the ongoing transfer if any happened. + </description> + + <interface name="zwp_primary_selection_device_manager_v1" version="1"> + <description summary="X primary selection emulation"> + The primary selection device manager is a singleton global object that + provides access to the primary selection.
