Understanding Actions and Variables
As you’ve learned in the preceding sections, each element added to your app (text, pictures, buttons, etc.) is considered an object. In addition to their visual qualities, most types of objects can also be used to perform tasks. Each object performs its tasks based on special instructions which tell VisualNEO Web what to do – these are called Actions. Actions assigned to objects are executed in response to specific events, including tapping or clicking, moving the mouse, pressing a key on the keyboard, etc. Not all objects are sensitive to all types of events. For example, Push Buttons can execute Actions when tapped or clicked or when the mouse passes over the object, while Timer objects are oblivious to mouse activity.
Pages too can contain Actions that execute whenever the user enters or leaves. Actions can be assigned to execute in response to specific app events like startup, orientation change, etc. (see App Properties).
