Web page interface

When the project is loaded, you can interact with the app natively with mouse and keyboard (partial implementation) or you can send specific JSON RPC messages using the area on the right.

The text area under the rendering viewport will display the JSON RPC response, log messages from engine, and notifications sent by the app.

The same application can be launched in full screen mode without log and command interface by removing the “dev=true” query parameter from browser address.

Device

Allows selection of the size to apply to the size fields and to the app, from a list of predefined values corresponding to common deployment targets.

Select an entry in the list to apply the corresponding size to the width and height fields.

The special value “Auto” automatically sets the size to match the available space in the browser app view.

The special value “Custom” is intended to be selected when entering custom values in the size fields (the Device selection is automatically switched to “Custom” when a custom value is entered in a size field).

Size

Clicking on a number in this menu entry enables editing of the number. It is possible to enter custom values to apply to the width and height of the app.

Width and height are subject to the following constraints:

• The maximum value for both fields is 9999.

• The minimum value for width is 200; the minimum value for height is 100.

• Width cannot be greater than height × 16.

• Height cannot be greater than width × 8.

When entering a custom value in a size field the Device selection is automatically switched to “Custom”.

Scale

Allows setting the scale used to display the app. Selectable values range from 100% to 10%.

The special value “Fit” scales the app view so that it fits within the available space in the browser app view.

“Fit” has no effect when the selected Device is “Auto” (since the app is already fitted to the container in this case), and it only takes effect when using fixed sizes, either custom values or ones selected from the Device list.

Orientation

Allows specifying the orientation of the view as either “Landscape” or “Portrait”.
