Scroll Area

A scroll area is a container that will add scrollbars around an element or group of elements, if necessary. It can also be used to clip content.

Position

ID

Give the element a unique ID or name. An ID is given automatically and will be numerically ordered when more than one are added. If an ID is already used by another element, a warning symbol will appear next to the input field.

★ Click the warning symbol to have Pano2VR create a unique ID for you.

Position

The X and Y coordinates for the element.

Logic Block available.

An element’s position is relative to its parent and to its anchored position (the Canvas is the parent to top level elements).

For example, a scroll area that is anchored and placed in the middle of the Canvas will have its anchor set to center and X and Y set to 0. So, if the element is anchored to the horizontal center, the X coordinate is measured from the center of the parent to the horizontal center of the element. Likewise, if an element is anchored right, the x-coordinate is measured from the right side of the parent to the right side of the element as indicated by the arrows. ★ Tip: Double-click the arrows to set X and Y to 0.

This makes it easier to precisely position elements, especially on the edges of the player. For example, to keep an element positioned on the bottom center of the player and a certain distance from the edge, set the anchor to center bottom and set the Y value to 20 pixels and X to 0.

X and Y:

  • Percentage – Unit to set the position of the element based on the player’s size/window.

  • Pixels – Unit to set the actual location of the element within the skin.

  • CSS – Select CSS as a unit to allow for changing units when a logic block has been added or to use calculations.

    • Example: Set the x position unit to CSS. Enter, 100px in the edit field. Add a logic block, choose a trigger and add 20% for the size, effectively switching units.

Logic Block available.

Anchor

Use this grid to “stick” the element to a section of the player window. See above, to learn how the Anchor influences Position.

Size

Adjust the element’s size (width and height) in pixels. Width and Height:

  • Percentage – Unit to set the size of the element based on the player’s size/window.

  • Pixels – Unit to sets the actual size of the element.

  • Lock Aspect Ratio – Click the link icon to lock the element’s size aspect ratio when resizing in the Canvas or changing size values in the properties panel.

  • CSS – Select CSS as a unit to allow for changing units when a logic block has been added or to use calculations.

    • Example: Position an element 50 pixels from the top and then set the height to calc(100% - 50px). The element will then always have the same distance of 50px from the top and will extend straight down to the bottom.

Logic Block available.

Appearance

Scaling

Scales the element along the x and y axes. Doubling the value on either axis, for instance, will double the size of the element. If a scaling modifier is enabled, this scaling setting is ignored.

Center

Use this grid to determine how the element scales. The default is set to the center so the element will scale in or out from its center. If you anchor the scaling to the upper left corner, for example, the scaling will center from this point.

Logic Block available.

Angle

Use this parameter to adjust the angle of the element. It will use the Center grid (above) as its axis. For example, if the center is chosen, it will rotate around its center. If the bottom left corner is selected, the button will rotate around that corner.

Logic Block available.

Visible

Select or deselect to keep the button visible or invisible. Visibility or invisibility can be changed and toggled with actions.

Logic Block available.

Alpha

The transparency of the button. A setting of 1.000 is opaque. Lowering this number will increase the button’s transparency.

Logic Block available.

Hand Cursor

Select to have the hand cursor show when the mouse rolls over the element. This makes it more obvious to the user that the area is interactive.

Rectangle

Background

Select Enabled to show the background of the scroll area.

  • Color – Use the color picker to choose a color for the background.

Border

The border or outline of the scroll area. Click the Toggle Single/Separate Values button next to each parameter to toggle between adjusting the entire border or adjusting each edge of the border separately.

  • Width – Defines how wide the border will be.

  • Color – Choose a color for the border.

Scroll Area

Inner Size

Define the area’s inner size which holds the child elements. If this inner size is smaller than the container, you’ll see the inner size defined by a dotted line in the canvas.

  • Width and Height – Enter the dimensions of the inner size and choose a unit of measure.

    • Auto – Select to have the inner size automatically sized to the extent of the child elements. All elements contained within the scroll area will need to have their sizes in pixels.
    • Pixels – Use to set a fixed width.
    • Percent – Useful for when a scroll area is within a Container and that container’s size is set with percent as well. The scroll area can then resize within the container.
    • CSS – Useful for when the inner size requires a mix in units to define limits. For example, if the inner size should have a height that is always 50 pixels from the top border and expand down to the bottom border, enter calc(100%-50px).
  • Alignment – If the inner size is smaller than the container, use this setting to specify the placement of the content (elements). When this is set, its effect will only be seen in the Live Preview window or on output. It will not be seen in the Canvas.

Scrollbars

Customize the look of the scroll bars.

  • Horizontal Scrollbar – Choose to have a horizontal scrollbar. Auto will add one if the content width is greater than the width of the Scroll Area.

  • Vertical Scrollbar – Choose to have a vertical scrollbar. Auto will add one if the content height is greater than the height of the Scroll Area.

  • Foreground – Foreground color of the scrollbar.

  • Background – Choose the background color of the scrollbar.

  • Corner – Choose the color of the corner square that is formed with the horizontal and vertical scroll bars come together.

  • Width – Change the width of the scrollbar in pixels.

Accessibility

Tab Index

To make skin elements controllable via keyboard, they have to be added to the tab order of the web page. A tab index of -1 (the default) excludes the element from the tab order. A tab index of 0 includes the element in the tab order. Browsers will highlight the active element by putting a rectangle around them. Once a skin element is the active element, indicated by the highlight, hit the Enter/Return key to trigger its click action.

ARIA Label, Description, Details

These are attributes or propterties that are used to define the element and support the Role.

Label – Defines or names the element. Description – Provide a brief description of the element. Details – Provide an extended, detailed description of the element.

ARIA Roles

ARIA Roles are used to define UI elements (button, loading bar, etc.). Choose from the list which best defines the element.

Hidden

Select to hide all ARIA attributes.

Advanced

Z-Index

Set the CSS z-index property. Use numbers to set the stacking order or leave the setting at Default. Default will use the stacking order set in the Tree.

This is used to ensure that elements are displayed in the correct stacking order especially when close or overlapping.

Permeable

Select to make sure the element does not accept mouse clicks. This is useful for when you want to include an element in the skin but don’t want it to hinder the ability to interact with the panorama. For example, you could add a vignette or logo or border that when clicked on, will allow interaction with the panoramas.

Hotspot Proxy ID

Enter the corresponding Skin ID. The ID should come from the hotspot’s Skin-ID field in the hotspot properties. Hotspot proxies give you the ability to link skin elements to specific hotspots. This means that the element will receive the same mouse and touch events as the hotspot. You can also add {} to use node ID as hotspot proxies. Learn more.

CSS Classes

Enter the CSS class names for the selected element. You can enter more than one class separated by spaces. If you need more space, click the Edit button to the right of the field for a larger text field. No dot . needed.

CSS Styles

Enter the CSS style attributes for the selected element. You can enter more than one style separated by semi-colons. If you need more space, click the Edit button to the right of the field for a larger text field.

CSS Styles Inner Element

Enter CSS style attributes for the selected element’s inner element. (Some skin elements, like Image, Video and External Image, have an inner element nested inside the element’s main <div>.)

For example, an image element can have a border: border-radius: 20px; border: 5px solid red;. This can also be entered with a line break: border-radius: 20px; border: 5px solid red;

Keyboard Shortcut

Enter the preferred key to control the action defined to the element. For example, select the text field, hit the up key on the keyboard. Then add a Mouse Click action. The element, when clicked or when the up key is pressed, will perform the assigned action.

Exclude from Translation

Select this option to not include this element in the skin’s translation file.

Actions

Actions or a set of directions can be applied to any element added to the skin to create interactivity.

Double-click in the Actions area or click the plus sign to the right to open the Action Settings.

See Skin Actions, for details on all actions.

Modifiers

Adding modifiers allows you to make elements move, scale or rotate when the panorama is being panned, tilted, zoomed or loaded. A good example of a use of a modifier is for a loading bar that scales in relation to how much of the panorama has been loaded. You can see how this is done by opening one of our default skins.

Double-click in the Modifiers area or hit the plus sign to the right to open the Modifier Settings.

See Skin Modifiers, for more details on all modifiers.

Notes

Use this section to add information about the element. This is especially useful if you have a component and want to explain the elements inside that component.

Notes will show up as tooltips in the Tree.
