Con* ewmh_get_workspace_by_index ( uint32_t idx )

Returns the workspace container as enumerated by the EWMH desktop model.

Returns NULL if no workspace could be found for the index.

This is the reverse of ewmh_get_workspace_index.

uint32_t ewmh_get_workspace_index ( Con * con )

Returns the EWMH desktop index for the workspace the given container is on.

Returns NET_WM_DESKTOP_NONE if the desktop index cannot be determined.

This is the reverse of ewmh_get_workspace_by_index.

Necessary to move tabs in Chromium correctly.

EWMH: These arrays contain all X Windows managed by the Window Manager. _NET_CLIENT_LIST has initial mapping order, starting with the oldest window. _NET_CLIENT_LIST_STACKING has bottom-to-top stacking order. These properties SHOULD be set and updated by the Window Manager.
