![]() The WCAG WG encourages submission of such techniques so they can be considered for inclusion in this document, in order to make the set of techniques maintained by the WCAG WG as comprehensive as possible. Use of the techniques provided in this document makes it easier for Web content to demonstrate conformance to WCAG 2.0 success criteria than if these techniques are not used.īesides the techniques provided in this document, there may be other techniques that can be used to implement conformance to WCAG 2.0. The World Wide Web Consortium only documents techniques for non-proprietary technologies the WCAG Working Group hopes vendors of other technologies will provide similar techniques to describe how to conform to WCAG 2.0 using those technologies. Currently, technology-specific techniques are available for HTML, CSS, ECMAScript, SMIL, ARIA, and Web servers. This document provides "General Techniques" that describe basic practices that are applicable to any technology, and technology-specific techniques that provide information applicable to specific technologies. Techniques are specific authoring practices that may be used in support of the WCAG 2.0 success criteria. because the user could be focused on some other window that has none of the controls of interest)."Techniques and Failures for WCAG 2.0" provides information to Web content developers who wish to satisfy the success criteria of Web Content Accessibility Guidelines 2.0 (WCAG 2.0). lots of NVAR, SVAR, and WAVE declarations throughout the code), and the latter requires careful consideration of where the user may be at run-time versus where the queries are to be directed at that same instant (e.g. Having coded with both approaches, I can say the former has overhead that can quickly become akin to clutter (e.g. The other queries the state of the panel controls only when needed. One method has the controls set globals (in root:Packages as Andy suggests) immediately as the controls are altered by the user. Or, if I might suggest otherwise, you can still check the GUI panel, but the code to do this is separate from the code that does the analysis. In the analysis function you then don't need to query all the checkboxes to see if they are checked or not, you just check the wave. Also, create different folders to store different datasets that you are analysing, makes things clear.Īnother perspective on the answers already offered here is to collect GUI state as you go along. In that way the root datafolder stays uncluttered. THe selection wave for the listbox holds it's state, so you only have to check that wave to query all the checkbox states.Īlso, really recommended is creating a datafolder root:packages:, to hold all the guff associated with the program. Listboxes have the advantage that they can scroll, etc. ![]() Another suggestion could be to collect the different types of analysis method (on the first tab) into a listbox. The same thing goes for other types of GUI widgets.ĭesigning GUI's are hard. You could even pass that wave to the analysis function (see separation of GUI and analysis above). Have a GUI function for all the checkboxes, when a checkbox is ticked, then it could set an entry in a wave stored somewhere. If you've designed the analysis functions well, the two should be relatively orthogonal.Īnother perspective on the answers already offered here is to collect GUI state as you go along. Once the analysis works well, then build the GUI on top. Add the test cases to a simple function you can call. ![]() Have specific test cases for the analysis, so you can reassure yourself that the analysis works. Get the analysis working well first, then test it. I wish I had known this when I started programming, it would've saved me countless hours of wasted time. In other words, write code that does the analysis, that you can call from the command line, but has no GUI interaction or dependencies on any GUI whatsoever (possibly to the extent where it doesn't rely on preexisting global variables/waves). The first tip, more of an essential rule, when doing any programming is separate the GUI code from the code that does the processing analysis. ).Ĭhemistry / Chemical & Materials Engineering, UAHuntsville Sprintf fname, "MyFunctionfor%s()", dowhat Ī more elegant solution may exist without the Execute statement, and a more complex method may be needed depending on what you are intending to pass to any given function (the same thing, a wave, a set of parameters, nothing. ![]() ![]() Variable nc = 4 // the number of controls here String tname = "tab0" // the name of your tab here String pname = "Panel0" // the name of your panel here Wide-Angle Neutron Spin Echo Spectroscopy. ![]()
