Dialogs

The dialog functions offer you the opportunity to interact with the user using modal windows that appear in front of the tapp.

They can be used to inform users about a task and can contain critical information, require decisions, or involve multiple tasks.

The dialogs are an independent part of chayns®. It's the same project loaded on all platforms.

### Dialog-chayns-js documentation

You get the full chayns environment in chayns.env, but most of the calls are not supported.
The [utility functions](https://github.com/TobitSoftware/chayns-js/wiki/Utility-Functions) are fully available. 
Also, there are a few special functions for dialog iFrames.

#### Communication with the tapp

The communication functions are also available in the tapp to communicate with the dialog.

- chayns.dialog.sendData(data, isApiEvent)
    - Allows to send data to the tapp. If isApiEvent is set, the data will only be recognised if getApiEvents is set on the following function.
- chayns.dialog.addDialogDataListener(callback, getApiEvents)
    - Allows to get the data sent from the tapp. If getApiEvents is set, only apiEvents are recognised.
- chayns.dialog.removeDialogDataListener(callback, getApiEvents)
    - Removes the listener.

**Note:** There's a queue to prevent that you miss some data.

#### Set button result

- chayns.dialog.setResult(result, register)
    - Sets an result which will be given back to the tapp when user closes the dialog using a positive button. 
    It can be set at every time. Set register, if you want to be notified before the dialog get closed (by the user).
- chayns.dialog.addDialogResultListener(callback)
    - Registers a listener that will be notified before the dialog gets closed. 
    After this listener get called, you have to set a result to close the dialog.
- chayns.dialog.removeDialogResultListener(callback)
    - Removes the listener.
