  • Overview Getting the Necessary Code and Files
    Softpress KnowledgeBase Using jQuery Code with Freeway Here we will run through the steps used to implement a jQuery horizontal scrollbar similar to the one which can be found at http://jquerytools.org/documentation/rangeinput/ so it can be used to make content within an item on a page scroll horizontally - but please note that we cannot give specific support or instructions for other JavaScript functionality you may find on the web. This is because the way the code is used and edited (sometimes by doing your own hand-coding) varies greatly from one to the next - and many of the sites which offer the code give very limited details of how it needs to be used, sometimes to the point that only those with excellent coding skills will be able to use it. As you will see, this is a long and complex procedure - and this will be the same with any other web design application unless a Freeway Action (or a similar method in other applications) is available to use to simplify the process. It is very important to note that mixing and matching JavaScript libraries on the same page will often cause conflicts. This means that using jQuery functionality on a page will break the Scriptaculous functionality used by many Freeway Actions. This will be discussed later in this article with a specific example. Sometimes this can be fixed by specifying some "NoConflict" code - however, this cannot be fixed with this particular jQuery function without a major rewrite of the supplied jQuery code. Overview We are often asked by customers how a particular website has used some special functionality, and they ask if this can be done in Freeway.

  • A Study on Interaction of Gaze Pointer-Based User Interface in Mobile Virtual Reality Environment
    S S symmetry Article A Study on Interaction of Gaze Pointer-Based User Interface in Mobile Virtual Reality Environment Mingyu Kim, Jiwon Lee ID , Changyu Jeon and Jinmo Kim * ID Department of Software, Catholic University of Pusan, Busan 46252, Korea; [email protected] (M.K.); [email protected] (J.L.); [email protected] (C.J.) * Correspondence: [email protected]; Tel.: +82-51-510-0645 Received: 7 August 2017; Accepted: 6 September 2017; Published: 11 September 2017 Abstract: This research proposes a gaze pointer-based user interface to provide user-oriented interaction suitable for the virtual reality environment on mobile platforms. For this purpose, a mobile platform-based three-dimensional interactive content is produced to test whether the proposed gaze pointer-based interface increases user satisfaction through the interactions in a virtual reality environment based on mobile platforms. The gaze pointer-based interface—the most common input method for mobile virtual reality content—is designed by considering four types: the visual field range, the feedback system, multi-dimensional information transfer, and background colors. The performance of the proposed gaze pointer-based interface is analyzed by conducting experiments on whether or not it offers motives for user interest, effects of enhanced immersion, provision of new experience, and convenience in operating content. In addition, it is verified whether any negative psychological factors, such as VR sickness, fatigue, difficulty of control, and discomfort in using contents are caused. Finally, through the survey experiment, this study confirmed that it is possible to design different ideal gaze pointer-based interface in mobile VR environment according to presence and convenience.

  • Chapter 11: Scrolling
    In this chapter: • Scrollbar • Scrolling An Image 11 • The Adjustable Interface • ScrollPane Scrolling This chapter describes how Java deals with scrolling. AWT provides two means for scrolling. The first is the fairly primitive Scrollbar object. It really provides only the means to read a value from a slider setting. Anything else is your responsibility: if you want to display the value of the setting (for example, if you’re using the scrollbar as a volume control) or want to change the display (if you’re using scroll- bars to control an area that’s too large to display), you have to do it yourself. The Scrollbar reports scrolling actions through the standard event mechanisms; it is up to the programmer to handle those events and perform the scrolling. Unlike other components, which generate an ACTION_EVENT when something exciting happens, the Scrollbar generates five events: SCROLL_LINE_UP, SCROLL_LINE_DOWN, SCROLL_PAGE_UP, SCROLL_PAGE_DOWN, and SCROLL_ABSOLUTE.In Java 1.0, none of these events trigger a default event handler like the action() method. To work with them, you must override the handleEvent() method. With Java 1.1, you handle scrolling events by registering an AdjustmentListener with the Scrollbar.addAdjustmentListener() method; when adjustment events occur, the listener’s adjustmentValueChanged() method is called. Release 1.1 of AWT also includes a ScrollPane container object; it is a response to one of the limitations of AWT 1.0. A ScrollPane is like a Panel, but it has scroll- bars and scrolling built in. In this sense, it’s like TextArea, which contains its own scrollbars. You could use a ScrollPane to implement a drawing pad that could cover an arbitrarily large area.
