Widget state table

A description of the states that can come as values in the state and prevState arguments of the onStateChange handler described above.

| state | description | widget visual state | |-------------------------------|--------------------------------------------------------------------------------------------------------------------------------------------------|---------------------| | INITIALIZING | Just after starting the chat. The previous state can be null. | The Widget is not render yet. | | READY | The chat received both a token and a channel, but the conversation has not yet begun. | The Widget is minimized. | | OPENED | The conversation has already begun and the Widget is visible open. | The Widget is expanded. | | MINIMIZED | The conversation has already begun, the Widget is visible in a minimized state. | The Widget is minimized. | | MINIMIZED_WITH_NOTIFICATION | The conversation has already begun, the Widget is visible in a minimized state. Can happen only if widget is minimized and new message received. | The Widget is minimized. | | FINISHED | The user has closed the chat that has already loaded new credentials. | The Widget is minimized. |

Widget public API

The widget offers a public API, which is described in the following table.

| function | args | description | |-------------|------|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | initResume |-| The function only exists in the <GeorgeChat /> component. It is called in a scenario specific to GeorgeWeb. The GeorgeChat component is mounted on the page each time it is rendered. At such a moment, GeorgeChat just checks to see if a conversation session has already started. If it is, it starts normally. If not, its further initialization is suspended due to resource savings. You need to call this function to continue initialization. | | postBack |action| Used to send a non-visual chat event. The 'start' value in action argument is used to start the conversation. E.g. postBack('start'); | | disconnect |endSession = true| Used to notify the widget that it will be unmounted so it can end performing conversation. Unmount is safe only after setting the FINISHED state. The true value in endSession argument is used when user click on Logout button. true is default value. The false value in endSession argument is used when user session expires. E.g. disconnect(false); | |reset|-| Function used to reset the conversation and start from the very beginning. Used mostly for OAI Bot, in conclusion to a full reload, after the reset is triggered. | | expand |-| Used to change widget state to OPENED | | minimize |-| Used to change widget state to MINIMIZED |
