Code Element

The code element is used to apply Javascript to the skin.

The code element is used to add custom Javascript and CSS. When the script is added with custom properties, they are added to the interface as parameters. The code element itself can then be saved as a component.

User-definable parameters added to the Javascript will show here as interactive settings.

Code

Use the text field to add Javascript. If you need more space, use the Open Editor button to open a larger editor.

The code can be saved and made to be used as an external file. Once the code is saved, From file will be selected and the path of the file will be added. To locate the file or change the path, right-click on the path to open the context menu.

Once code is added as an external file, the editor becomes read-only.

The code can contain a special comment block that must be at the beginning of the code. It must start with /*! and end with */. Inside that comment, you can include css styles enclosed in a <style> tag.

Further, you can specify custom properties for the code element. The custom properties are defined in a JSON object called ggproperties. The example below demonstrates how to define custom properties, what types of properties we support, and how to use the values from those properties in your Javascript code.

And finally, a code element might be using skin variables. When a code element is copied (to paste it into another skin), or made into a component, it’s likely you’ll want these skin variables to come along with the code element. To do this, specify the variables in a JSON object, called ggvariables, in the same comment block. In the example below, we define that skin variables var1 and var2 have to also be copied if the code element is copied or put into a component.

Here is an example of such a comment block (plus some Javascript code at the end) containing everything mentioned above. In practice, not everything has to be present. Or if none of this is needed, you can omit the comment block all together:

/*! <style>  .myclass {  font-family: "Times", serif;  line-height: 1.3;  font-size: 20px;  padding: 10px;  }   .glow {  -webkit-filter: drop-shadow(0px 0px 3px rgba(255, 255, 255, 0.5));  filter: drop-shadow(0px 0px 3px rgba(255, 255, 255, 0.5));  }   .shadow {  -webkit-filter: drop-shadow(0px 0px 3px rgba(0, 0, 0, 0.5));  filter: drop-shadow(0px 0px 3px rgba(0, 0, 0, 0.5));  }  </style> {  "ggproperties": [  {  "id": "transparency",  "type": "checkbox",  "label": "Transparent",  "default": true  },  {  "id": "text",  "type": "text",  "label": "Text field",  "default": "Add your text here."  },  {  "id": "int_var",  "type": "spinbox",  "label": "Integer Number",  "default": 42  },  {  "id": "float_var",  "type": "doublespinbox",  "label": "Float Number",  "default": 3.141  },  {  "id": "color",  "type": "color",  "label": "Text Color",  "default": "blue"  },  {  "id": "color2",  "type": "combobox",  "label": "Background Color",  "default": "red",  "values": [  { "label": "Black","value": "black" },  { "label": "Red", "value": "red" },  { "label": "Blue", "value": "blue" }  ]  }  ],  "ggvariables" : [ "var1", "var2" ] } */ // Now you can use those classes and properties in your code console.log("Text: " + el.ggproperties.text); el.className += " myclass shadow"; el.style.color = el.ggproperties.color; el.style.background = el.ggproperties.color2; el.innerHTML = el.ggproperties.text; 

External Files

External files are used for sharing Javascript Code elements as Components. Any files that the element is dependent on will be made part of the component and then included when the component is added to a skin.

To add a file, click the plus button at the right of the row or double-click in the table. Choose if the file should be a CSS or JavaScript file, then enter the URL.

Local Files

In the local files table, you can add files from your hard drive that will be included in the skin file and will be copied to the output folder on output. An example would be adding font files that you want to use in the CSS styles defined in the code element.

To add a file, click the plus button at the right of the row or double-click within the table. Navigate to the file. The file will appear in the table. You can now edit the file name in the table by clicking the file. This will then be the file name used when it is copied to the output folder. You can prepend a subfolder so the file will be copied to a subfolder in the output.

For example, you could add a font file from your hard drive, myFont.ttf. Then, edit the file name in the table to fonts/myFont.ttf. When the output is created, this file will be copied to the output folder, in a subfolder called fonts.

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.

Point Hotspot Templates will have a menu that shows all the default template IDs as well as any template IDs used in the project.

Position

The X and Y coordinates for the element.

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 video 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.

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.

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

The Hotspot Template and Node Marker do not have a size parameter.

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. This button is reset to off when another element is selected.

• 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.

• Reset Size – Available for Image, Button, and SVG elements. Click to return to the image’s original size.

• Reset Size/2 – Available for Image, Button, and SVG elements. Use this when you want to add a PNG or JPG to your project but still want it looking sharp in Hi-DPI displays. For example, if the skin requires a 32px image, use a 64px image and then click, Reset Size/2. This will then make it 32px in the skin but will still have all the pixels for a high resolution display.

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.

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.

Visible

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

Alpha

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

Cursor

Choose which cursor shows when the mouse rolls over the element.

Inherit – The element will inherit the cursor from its parent element. This is the default for all elements except Button and Seekbar.

Hand – The hand cursor will show. This is the deafult for Button and Seekbar elements. When selected, the cursor is not inherited from its parent element.

Default – Choose this option to force the browser’s default cursor (usually an arrow). When selected, the cursor is not inherited from its parent element.

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 ID. The ID comes from the hotspot’s 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 (mouse click, mouse double-click, mouse enter, and mouse leave). 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.

Safe Area

Available for the Container Element.

Select Use Safe Area for Position and Size to keep child elements of the container inside the safe area of the device. This option makes sure that the elements are always 100% visible and the skin will automatically react to the device’s safe area.

Make sure Ignore Safe Area is not select in the HTML template settings in the Web Output.

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.

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.
