Dynamic Lopa
============

Starting from V3.2, the FTools user web interface provides a dynamic LOPA in place of
static LOPA figure.

Besides the main view, the dynamic LOPA provides 3 zones (numbers refer to :numref:`fig_lopa_01`):

* 1: Manipulation Tools (*cf* :ref:`dynamic_lopa_tools`) 
* 2: Hover Selectors (*cf* :ref:`dynamic_lopa_hover`) 
* 3: Layups Selectors(*cf* :ref:`dynamic_lopa_layups`)

Dynamic LOPA Tools
------------------

The Zone 1 provides a set of convenient tools to manipulate the view:

* 1: Pan Tool. Click and left-drag (mouse device) to translate the view
* 2: Box Zoom: Click and select the details to zoom-in
* 3: Scroll Zoom: use the mouse scroll wheel to zoom-in/out. Convenient when combined with Pan Tool.
* 4: Reset View. Once done with zoom/pan, you can reset the view to its global aspect by clicking on it.
* 5: Save image: Click to save image on your disk

.. _dynamic_lopa_hover:

Dynamic LOPA Hover Selectors
----------------------------

Hovering consists in displaying selected data as mouse is moving over an *item*. The Dynamic LOPA provides several item families: rails, crossbeams, zones, seats, attachment points, etc... When using mouse hovering, it may be convenient to *deactivcate* some data to show. This is the point of those selectors.

Figure :numref:`fig_hover_messy` shows a messy hovering action, since all the hover selectors are activated (highlighted in red). This leads to many superposed tooltips.

    :figclass: align-center

    Hovering with all hover activated can be a bit messy

Activating only the *seats* hover selector makes tooltips plot more predictable, as shown in :numref:`fig_hover_OK`.

    Deactivating some hover selectors is easing the hovering



.. _dynamic_lopa_layups:

Dynamic LOPA Layups Selectors
-----------------------------

Several Layups are available to the users. The Layups Selectors toolbar provides a way to hide/show those layups. Hidden layups are shown white on the toolbar, active (visible) layups are shown as green. Clicking the layup icon will toggle its status.

For some of the layups (*seats*, *others*, *seats_attach*, *other_attach*), a combo box provides different way of *colouring* the relevant items.
