====== qckHuD ======

qckHuD is an addition to qckPck that will displays a variety of information about the current scene as well as items as an overlay.

The type, location and colour of the information can be configured.

qckHuD is a master plugin that is saved with the scene. It comes with four generic plugins which can be added to a menu or attached to a shortcut:

  * **Add qckHuD** Adds the plugin to the current scene, if it's not a part of it yet, and opens the user interface.
  * **Show qckHuD** Shows the qckHuD overlay
  * **Hide qckHuD** Hides the qckHuD overlay
  * **Toggle qckHuD** Toggles the visibility of the qckHuD overlay. Best assigned to a keyboard shortcut.

===== qckHuD Master Plugin =====
Opening the master plugin displays a user interface to edit the overlays for the current scene. This user interface can be resized freely.

==== Presets ====

This uses the same presets system as our other plugins: [[exrtrader2018:presets|]]
==== About ====
==== List of Overlays ====

This displays a list of all current overlays.

==== Overlay List ====

This displays all overlays. You can drag and drop items to re-arrange them. Hierarchies of items are supported.
The Viewport column shows for which viewport types the overlay is being used: **O**rhtogonal, **P**erspective, **L**ight, **C**amera or **S**chematic view.

The second column shows a rotate icon if the overlay (as well as it's children) will be used for multiple selected items.

The third column shows the overlay text itself.

You can left click on this list to select an overlay item to edit. Right clicking on an item opens a context menu:

  * **Add** \\ Adds a new overlay at the end of the list
  * **Add Child** \\ Adds a new overlay as the child of the current selection
  * **Remove** \\ Removes the current item. If it has child items, you will be prompted if you really want to delete it, including the children.
  * **Export Selected...** \\ Exports the selected item (and children) as a file.
  * **Import** \\ Imports a file saved with export. The imported overlays will be added to the list.

=== Add Overlay ===

This adds a new overlay to the end of the list.

=== Add Child Overlay ===

This adds a new overlay as the child of the currently selected item.

=== Remove Overlay ===

Removes the current item. If it has child items, you will be prompted if you really want to delete it, including the children.

=== Overlay ===

This is the text displayed as an overlay. You may include any of the available [[#Variables]] to dynamically extract data from the current scene.

=== Hide if not used ===

If the overlay contains variables, but none of them can retrieve any data in the current context (i.e. light information but you have a bone selected) then the overlay will not be displayed at all and ignored.

=== Append Variable... ===

This appends any of the selected [[#Variables]] to the current overlay.

=== Append Item... ===

This appends the selected item name as a variable limiter. See [[#Variables]] for more information.

==== Overlay Properties (right hand side) ====

These controls allow you to edit the individual attributes of every overlay.

=== Enabled ===

This enables or disables the current overlay completely, including children.

=== Loop Multiselection ===

If multiple items are selected, this overlay - as well as all children - will be displayed for every selected item.

=== Use Parent Style ===

This option is only available if the overlay is a child. It will inherit all of the following options from the parent overlay item.

=== Viewport Visibility ===

This defines when this overlay is visible in a viewport.

  * **Always Visible** The overlay is always visible
  * **Active Viewport only** The overlay is only visible in the viewport you're interacting with. This is triggered by the first mouse interaction in a viewport.
  * **Inactive Viewport Only** The overly is only visible in a viewport you're //not// interacting with. Essentially the opposite of the previous option.
  * **Never Visible** This effectively disables the overlay

=== Viewport Type ===

This defines which kind of viewport the overlay will be visible at.

=== Overlay Position ===

Overlays can be positioned along the sides of viewports or the centre.

=== Colour ===

This defines the colour of the overlay text.

=== Opacity ===

This defines the opacity of the text.
==== Background ====

The following controls allow you to enable a background for each of the 9 possible overlay positions. You can also change the colour as well as the opacity.

=== Position ===

This selects the background position to edit.

=== Enable ===

En- / disables the background for the current position.

=== Colour ===

Defines the colour for the background.

=== Opacity ===

Defines the opacity for the background.

===== Variables =====

Variables need to be enclosed in % within the overlay, i.e.
  Scene: %scene.name% - %scene.num_polygons% polygons
  
Variables related to specific items can be limited to a specific item as opposed to the current selection.
This is done by adding the item name in front of the variable, designated by a $, i.e.
  $my_Camera%camera.zoom%
  
If you actually want the characters % or $ to show up in an overlay, just type them twice. %% shows a single %, $$ a single $.
