those that are pressed when the Enter or Escape are pressed). In addition to simply specifying the button text, there needs to be consideration over whether to allow for customising the button graphic, or modifying the default action of the button (the alternative is that the button always hides the dialog without question), and finally being able to specify which button is the ‘default’ or ‘cancel’ buttons (i.e.
#JAVAFX BUTTONBAR VS TOOLBAR HOW TO#
From my experience, the most complex aspect to customising dialogs (from an API perspective) is how to specify and configure the buttons to show to the user. There are a number of ways a dialog can be customised – but typically it falls down to a desire to change one or more of the the title, masthead, content or buttons areas. I typically refer to these two approaches as ‘high-level dialogs’ and ‘low-level dialogs’. The other common use case is only ever considered by developers when the simpler use case fails them: they find the simplest API that allows for them to customise the dialog to suit their needs. warning, confirmation, information, etc) with a pre-specified set of buttons, and to just specify the message (and related attributes), before returning the selected button to the developer so that they may react accordingly. In other words, the most common use case is to simply show a common dialog type (i.e. There are typically two common use cases for a dialogs API, and they only differ in how much time the developer needs to spend to bring the dialog up. However, some common areas include the title area, the masthead area (which is an area beneath the title and above the content for showing bold text and / or graphics), the content area (where the message or other nodes can be placed), and the button area. Some benefits of lightweight dialogs is that they do not need a windowing system and are therefore more friendly on some touch devices.ĭialogs consist of a number of areas, and what the JavaFX dialogs consist of is still up for discussion. My personal preference has been to always use heavyweight dialogs, but in my experience in developing dialogs for ControlsFX (more details below), I have been surprised by how popular and how commonly used the lightweight dialog has been. I’ve always referred to these concepts (incorrectly) as heavyweight and lightweight dialogs, and I will continue to use this as my way of classifying the two types of dialog in this document. not in a separate window but embedded within the scene of their owner). a JavaFX Stage), or they may be ‘internal’ (i.e. The alternative approach is to require callbacks to be called once the dialog is closed, but rarely is this the kind of interaction that a developer wants.ĭialogs can either be in their own top-level window (i.e. This is beneficial as it means you can show a dialog, wait for the users response, and react accordingly.

Normally they block input to its owner, and normally they are modal, stopping the execution of the calling code until they return. What is a Dialog?Ī dialog is a popup that appears when the user needs to provide some input.

If this is the case, please email me at and I’ll be sure to update this document. In this document I hope to outline what dialogs can mean in an attempt to get everyone on the same page, and from there decide on how best to advance JavaFX into the dialogs era! I should note that I am basing this document on my own perspective and understanding, and I am maybe forgetting or misunderstanding concepts.
Dialogs can mean different things to different people, and with this comes different expectations over how an API should be formed. If you have comments as a result of this blog post, you are also encouraged to send them in to RT-12643. You can follow along at home with the RT-12643 Jira issue. JavaFX has never had a dialogs API, which has always seemed to be a glaring omission – but no more! It has (finally!!!) been decided that JavaFX 8u40 will be the first release that will include a dialogs API.
