Method Details

createPopup

UiPopup createPopup(UiNotification notification,
 UiAction... actions)

This method creates a popup window with the given message. It is the most generic and flexible but also the most inconvenient showPopup method variant.

Parameters:

notification - the UiNotification to show.

actions - are the UiActions for the buttons to close (answer, confirm, or cancel) the popup. Has to be at least one UiAction.

Returns:

the UiPopup.

createPopupOk

default UiPopup createPopupOk(UiNotification notification)

This method creates a popup window with the given message. It is the most generic and flexible but also the most inconvenient showPopup method variant.

Parameters:

notification - the UiNotification to show.

Returns:

the UiPopup.

createPopupOk

default UiPopup createPopupOk(UiNotification notification,
 UiActionOk action)

This method creates a popup window with the given message. It is the most generic and flexible but also the most inconvenient showPopup method variant.

Parameters:

notification - the UiNotification to show.

action - the optional UiActionOk to invoke when OK is pressed and the popup is closed.

Returns:

the UiPopup.

createPopupYesNo

default UiPopup createPopupYesNo(UiNotification notification,
 Consumer<Boolean> callback)

This method creates a popup window with the given UiNotification and two buttons for the options yes and no.
ATTENTION:
This is a very convenient but also very often misused feature of UI toolkits or frameworks. A suitable example is e.g. to use this with the message "Do you really want to delete this object?". However, it would still be more explicit to have the buttons labeled with "Delete" and "Cancel" using createPopup(UiNotification, UiAction...). A famous example for a misuse of this method would be the question "Do you want to delete this occurrence or the series of the appointment? Press 'Yes' to delete the series and 'No' for this occurrence.". From this bad example that confuses the user, you should learn that it is always better to use more explicit button labels.

Parameters:

notification - the UiNotification to show. Should have UiSeverity.QUESTION.

callback - is the Consumer invoked after the popup has been confirmed. Consumer.accept(Object) will receive Boolean.TRUE if the user clicked "Yes" and Boolean.FALSE for "No".

Returns:

the UiPopup.
