UI Functions                                                          *api-ui*

nvim_ui_attach({width}, {height}, {options})                *nvim_ui_attach()*
    Activates UI events on the channel.

    Entry point of all UI clients. Allows |--embed| to continue startup.
    Implies that the client is ready to show the UI. Adds the client to the
    list of UIs. |nvim_list_uis()|

    Note: ~
      • If multiple UI clients are attached, the global screen dimensions
        degrade to the smallest client. E.g. if client A requests 80x40 but
        client B requests 200x100, the global screen has size 80x40.

    Parameters: ~
      • {width}    Requested screen columns
      • {height}   Requested screen rows
      • {options}  |ui-option| map

nvim_ui_detach()                                            *nvim_ui_detach()*
    Deactivates UI events on the channel.

    Removes the client from the list of UIs. |nvim_list_uis()|

        Since: 0.1.0

                                                    *nvim_ui_pum_set_bounds()*
nvim_ui_pum_set_bounds({width}, {height}, {row}, {col})
    Tells Nvim the geometry of the popupmenu, to align floating windows with
    an external popup menu.

    Note that this method is not to be confused with
    |nvim_ui_pum_set_height()|, which sets the number of visible items in the
    popup menu, while this function sets the bounding box of the popup menu,
    including visual elements such as borders and sliders. Floats need not use
    the same font size, nor be anchored to exact grid corners, so
