This restriction aids in the portability of the user-interface across multiple computers and operating systems. Brief Bioinform , 3: — We use sequences from SCOP version 1. Motifs are evolved using a subset of regular expressions to describe sequences in a superfamily or fold, and discriminate between these and sequences in other superfamilies folds. Solidify your understanding of JavaScript and prepare for technical interviews. Namespaces Book Discussion. Programming With Xt and Motif The quickest way to understand the basic Motif programming model is to examine a simple application. Want to Read Currently Reading Read. Developing Initial Class Cards To determine whether two methods have statistically different ROC or ROC scores on a particular benchmark, we use signed rank tests. Alexios added it Oct 25, Furthermore, by combining the Hamming distance and the logical disjunction operators, we can boost the importance of amino acid residues at specific positions in the pattern. First, ensure the devotools package is installed: install. The first and most important step in the development of an application is its design. Since Xt allows applications and users to override, augment, or replace translation tables, many people familiar with Xt try to specify a new translation for the DELETE key to make it act like a backspace. All All Chris Mosh Hamedani. This was in vogue, however, as Microsoft Windows 3. The file is a tab-delimited table. If a user wants to specify the color of the button label for the application, she can use the following specification in a resource file: hello. Complete instructions for compiling the examples using imake are provided in the README file included with the source code. Programming with Motif Writer The most important aspect of this is that if a widget is left unmanaged, it will remain invisible even when the parent is displayed. There are some things to be careful about when you are getting resource values from a widget. You invoke imake using the xmkmf program. We've looked at a simple Motif program to introduce the basic concepts in building the graphical user interface. Xt handles the dispatching of events to the appropriate widgets, which in turn pass them to the application via callbacks. An example of how fallback resources can be used by an application is shown in the following code fragment:. Reading room Community portal Bulletin Board Help out! However, in order to be useful to the application programmer, a widget must be easily attached to application functions. Motif widgets provide callback resources to support their expected behavior. For each widget class, there are many resources that neither the application nor the user should ever need to change. Other books in the series. The widget data structure is an exception to this rule. Jump to site search. One of these toolkits is Motif. For example, since we've set the width and height of the PushButton in the call to XtVaCreateManagedWidget , a user resource specification of the following form is ignored:. Since X is a distributed windowing system, once the application runs on a particular computer, it can be displayed on any computer running X--even across a local or wide-area network. Note, however, that there is no requirement that an app-defaults file with this name actually be installed. Actions are mapped to events in a translation table. This service is more advanced with JavaScript available. This routine contains the code that displays the button as if it were "pushed in," as opposed to "pushed out. If there is no match, the event is thrown away. A convenience function has direct access to the internal fields in a widget's data structures, so it might have slightly better performance than XtVaSetValues. The numerous examples cover the basics and explore ways to use UIL to facilitate rapid prototyping. React is the way forward to building fast, interactive web apps. It may be worth while looking at the code for the library class UILApp , its header file and, of course, the UIL interface sepcification. The language procedure is called by XtDisplayInitialize. For the most part, when we talk about widgets, we include gadgets. The file is parsed in the current locale. Back to tab navigation Download options Please wait Programming with Motif Reviews For example, the actual resource name associated with XmNlabelString is labelString. It is used to reference and set resources common to the application or even to a collection of applications. Sequence comparisons are based on the assumption that similar sequences share a common ancestor — that is, they are remote homologues — suggesting structural and functional similarities. App Builder is a good learning tool. Other books in the series. The current release that most Linux distributions ship is Open Motif 2. Proteins have the same common fold if they have the same major secondary structures in the same arrangement and with the same topological connections. Contributors 3. As illustrated above, the application itself may interact with all layers of the windowing system, the operating system, and other libraries math libraries, rpc, database as needed. Young , Trade Paperback. To ensure that our performance estimates are unbiased, we therefore create a separate set of motifs for each of the superfamily and fold test sets. In this case, you need to make sure that the variable is global, rather than local, since a local variable loses its scope outside of the routine that calls XtAddCallback. However, in order to be useful to the application programmer, a widget must be easily attached to application functions. Especially, the BLAST-based methods have difficulties producing effective alignments between related sequences at the fold level. The fold benchmark has sequences from superfamilies and classifiers are made for 86 of these. The figure shows how the SCOP database is divided into training and test sets. If you do pass any parameters, it should be done just as we describe for XtVaCreateWidget later in this chapter. Depending on the design of the widget, the action routine may then pass control to an application callback function. To modify a resource value, you should use XtVaSetValues with a defined resource name, as this routine ensures that the widget redraws and manages itself appropriately. While we use the variadic functions almost exclusively in this book, you should know how to use the old-style argument lists needed by the Motif widget creation functions. Motif has the further job of ensuring consistent user-interface behavior across applications. Putting It All Together The second parameter is used to pass client data to the function. You must use a compiled language to access the full power of the environment. LessTif aims for full source and binary compatibility with Motif. Other resources could have been set in the same call, as shown in the following code:. By convention, the class name is the same as the name of the application itself, except that the first letter is capitalized. Our method uses this inherent structure to create a kernel based on a rich set of motifs that tries to capture information about all related sequences in a particular dataset. Note that the command line may be used to set certain resources in X. Figure 2. These behaviors are the kinds of things that are captured in the widget's translation table:. Although this result may not be surprising — the two methods rely on distinct features — it suggests that the two methods can be combined to create an improved method for remote homology and fold detection [ 40 ]. These graphs show that the two methods are not redundant, but complementary. The reason field always contains a symbolic value that indicates why the callback was called. As of version 2. Each widget in Motif is provided by default actions. After the release of Open Motif there is now a second alternative to replace Motif for open source applications. The negative test set consists of one random family from each of the other superfamilies and the negative training set has the rest of the families in these superfamilies. You should check your local system documentation for the exact compilation directives. GUI Construction The easiest way to produce your first Common Desktop Environment application, and perhaps the fastest, is to do almost no Motif toolkit programming at all. As you make changes to your application's user interface, App Builder merges your custom code with the code it generates. Virtual keysyms can be invoked by physical events, but the Motif toolkit goes one step further and defines them in the form of virtual bindings. Google Scholar. Master all the. Chapters on each of the Motif widget classes, explaining them in depth, with useful examples that will help you to improve your own code. Mach Learn , 20 3 — Edited by: Yao X. Later chapters make it clear when to use gadgets and when to use widgets. Programming with Motif Read Online Driving the Animation A ROC curve is a plot of a classifier's sensitivity as a function of its specificity for different classification thresholds. The Gist package version 2. Nelson Yang marked it as to-read Jun 01, Proteins in SCOP superfamilies show low degrees of sequence identities, but structural and functional features in the proteins give them a probable common evolutionary origin, meaning that proteins clustered in superfamilies are likely to be homologues. Since the language procedure is responsible for setting the locale, an Xt application does not call setlocale directly.
