This page is for application designers. It explains how to set up actions in response to an event, such as a user mouse-click.

Overview

Often in an application, you want to trigger an action based on the user:

  • either mouse-clicking on the screem
  • or pressing the enter key.

These user interactions are called events. In PhixFlow you can configure event handlers that respond to events by running a table-action or actionflow.

  • OnClick: the user mouse clicks in an area.
  • OnEnter: the user presses the Enter key in a data field.
  • OnBlur: the user mouse-clicks out of a data field.
    The event is triggered whether or not the field has changed.
  • OnChange: the user mouse-clicks out of a data field in which they have changed data.
    Notice that this event is not triggered by the user typing into a field.

You can set event handlers on the following components:

EventSupported componentsOnClick
OnChange
AreaOnBlur
OnEnter
OnChange

Data fields:

  • Boolean
  • Date
  • Datetime
  • Number
  • String
Tip

You do not have to configure OnClick events for button components, because button actions are always triggered when the user mouse-clicks on them.

Adding an Event Handler

  • From the screen, click on a component to open its properties.
    • In the Event Handler section, click  Insert excerpt_Add_Addnopaneltrue to create a new event handler.
  • PhixFlow opens a new properties tab for the event handler.
  • Select the Event Type, Action Method and specific table-action or actionflow you require; see the properties below.
