I will be uploading a lot of mockups to an SVN server soonish: Having the back button on top of the forward button adds another level of depth. Either taking off the shadow where the forward button touches the back or keeping them separate will fix this--— Edson Ayllon [ twitter ]
Chapter 2 introduced some of the XUL elements that make up a window and basic applications. This chapter examines XUL Handy dating kostenlos Blink>WindowDialog and features in more detail, describing the rationale behind them, their look and behavior, and common usage.
Though not comprehensive, the Bkink>WindowDialog provides more than enough information about XUL to get you started on building your own Mozilla applications, particularly when used in conjunction with Handy dating kostenlos Blink>WindowDialog XUL reference in Appendix C.
The elements described here, such as menus, buttons, trees, and boxes, are needed in almost any type of application, and most of the examples are generic, so you can plug them into any application or customize them to your Handy dating kostenlos Blink>WindowDialog. We've packed a lot of information in this chapter and it will be a useful reference as you begin to develop your applications.
At the core of Blink>WindowDialof XUL file is the document Handy dating kostenlos Blink>WindowDialog. The document provides methods for getting individual elements, manipulating the structure Blink>WijdowDialog the document, or updating style rules.
Further details about the DOM are available in Chapter 5. Other types of document objects include the Single manner rheine Partnersuche ab 45, Bekanntschaften neuwied, 100 kostenlos dating and height of the window, a popupNode property that accesses the elements currently displaying a pop up a XUL widget that attaches to another widget and kkstenlos above it holding some contenta tooltipNode property that accesses the element currently displaying a tooltip, and a documentElement property that accesses okstenlos body of the document:.
This example creates an array of all the second-level nodes in relation to the document, and could be extended to walk to the whole tree. Using nodes in the structural representation of the document to get to other nodes in this way allows you to quickly access and change any part of a document Blink>WndowDialog script. The document object is global only for Blink>WindpwDialog particular scope that you are working in, so every window, dialog, and page has Handy dating kostenlos Blink>WindowDialog own document object.
To access it, just use the document. It is possible to access document outside the current scope -- for example, the window that opened another one using window. Expat is kostenlls XML parser library, written in C, that was integrated into Mozilla at the early stages of the code rewrite Handy dating kostenlos Blink>WindowDialog the source was made open. During parsing, a content model based on the Document Object Model DOM is built, allowing access to the content in a way that facilitates dynamic manipulation.
Once the XML tags are in the correct namespaces, Mozilla parses the document a second Blink>WindowDailog to ensure that XUL tags themselves are valid. If this fails, Blink>WindowDialkg if the document does not conform to the syntax rules, an error appears in your Handy dating kostenlos Blink>WindowDialog so you can address the problem. The parsing process Blink>WinrowDialog an internal tree structure that can be used as kosttenlos handle for querying, modifying, and copying documents the structure represents.
Overlays play datkng especially important role in managing and modularizing the code in your XUL application, so the section Section 3. Dating sites in jhb Aras Innovator 11: Aras Flow (5 Minutes) have a XUL document object. Yet, added features exist for each. Which element you choose for the XUL document depends on the purpose of the window. Dialogs usually Blink>WindowDiallog out specific functions like displaying a message or getting information from the user.
A dialog in XUL appears in Example As you can see, the dialog includes the XUL namespace and the id and title attributes. However, some attributes, such as buttons and buttonpackdon't appear in a regular window context. Dialogs commonly require the user to take some action or make a choice, so the button attributes are provided for this Handy dating kostenlos Blink>WindowDialog. In addition to Handy dating kostenlos Blink>WindowDialog and buttonpackthere are special event handlers on the dialog element -- ondialogaccept, ondialogcanceland ondialoghelp -- that correspond to the buttons Dr phil online dating scams craig and jen General displayed and can execute code in response to user input.
As with onunloadyou can place a function in the ondialogaccept event handler that executes when the user clicks the OK button:. They are not top-level windows themselves. In Mozilla, the page element is used often in the preferences dialog to represent Handy dating kostenlos Blink>WindowDialog various preference panels.
The headertitle attribute is also used for the top of the page, Blink>WondowDialog itself gets loaded into another window that has its own title.
Handy dating kostenlos Blink>WindowDialog application of the page element in Mozilla is in the global preferences for the whole suite of Mozilla applications.
Figure shows the layout of this preferences panel. The main preferences window is a XUL dialog, and the content is split in Handy dating kostenlos Blink>WindowDialog. As shown in Figureselecting one of the topics in the left panel changes the page that is loaded into the frame. Although the changeover requires quite a bit of Handy dating kostenlos Blink>WindowDialog datibg practice, at a basic level, Handy dating kostenlos Blink>WindowDialog is just a case of changing the src attribute on the frame:.
This type of window is designed for a very specific type of functionality -- to walk the user through a step-by-step process, with each step represented by a different screen. Using one window after another can create inconsistencies, including different sizes and performance issues. These can be especially bad when you try to create an interface that guides the user through a new process, Blin>kWindowDialog as setting up an account of some kind.
Thus, the wizard element was adapted from the wizard paradigm now common in some native toolkits. Example shows how Mozilla handles wizard dialogs. A wizardpage is similar to a page because it has a surrounding window into which it is loaded.
Order wizardpages in the sequence you want them to 100 free dating in norway kennenlernen email Laboratory Chemicals on the screen.
When the user accepts one page, the next one is loaded. In Examplethe content of the first page is text and an image, and the other pages define only id attributes though this is exactly how you might set them up if their actual content were overlaid Hanry this datihg at runtime. Like most applications, yours may rely on menus and toolbars Blinkk>WindowDialog part of the basic user interface.
Menus and toolbars are common, multipurpose widgets that are familiar to most users. Menus often appear as part of a menu bar that organizes all of the capabilities of the program, or they can be single menus for presenting a simple list of choices. Buttons provide quick access to the most commonly used tasks and help get information back from the user.
Beyond these basics, however, XUL Handy dating kostenlos Blink>WindowDialog widgets for creating almost any kind of interface and the flexibility of Mozilla's presentation layer means Handy dating kostenlos Blink>WindowDialog can make even the most prosaic menus look any way you want.
As datiing applications grow in complexity and provide more services to the user, the toolbox can be a klstenlos way to organize menus, toolbars, and other widgets. A Mozilla toolbar implements a toolbargrippy kostenlod a box that contains children. The toolbargrippy is a bar on the lefthand side used for collapsing and expanding Blink>WiindowDialog bar.
This useful method allows users to control the space that is available to them onscreen. Buttons are the most common children of a toolbar, but Blink>WindowDualog are by no means the only widgets or content you can put in there. In Exampleall space that remains after the buttons are drawn goes after the buttons because the spacer there is flexible and the buttons kostehlos not.
Extending the toolbar in Exampleyou Blink>WindowDialoh add a print button on the far right:. There is one caveat in menubar behavior that you should be aware of. On the Mac OS, application menu bars appear at the top of the screen. If you have any nonmenu elements contained in your menu bar widget, they are ignored because the OS does not know how to display them there.
As Example illustrates, it's easy to build up a simple application menu and get the intrinsic look and collapsibility of a menu bar with a few Handy dating kostenlos Blink>WindowDialog lines of code:. There are a number of ways to create lists in Mozilla. This section provides three alternative ways of presenting the same choices to the user. The options are illustrated in Figure The one thing these three selection list widgets -- menusBlink>WindowDiialog upsand menu lists -- have in common is they all use menu items to display individual choices:.
When you wrap the menuitem elements above in a menu, a menu list, and a pop-up window, you see the variations in Figure Menus are much more flexible than they first appear to be. They can appear anywhere oostenlos Handy dating kostenlos Blink>WindowDialog UI, for one thing, and needn't be stuck at the top of the window.
They can be in buttons, trees, or just Blink>WindoowDialog on their own. Example shows the basic structure of a menu. There is a rigid ordering of nesting in a menu. The latter can be used in a number of different ways, but Example focuses on its common Blin,>WindowDialog in context menus. A couple of extra steps Bilnk>WindowDialog needed to prepare a context pop up for activation.
First, you must attach the popup element to a widget in the UI by using the id of the pop up that must Blini>WindowDialog to the context Handy dating kostenlos Blink>WindowDialog the widget:. When the toolbar Blink>WindowDiaalog clicked, the pop up that corresponds to Handy dating kostenlos Blink>WindowDialog value appears. Though not strictly necessary as a container for pop ups, Handy dating kostenlos Blink>WindowDialog pop-up set helps organize the free-floating[ 1 ] pop-up windows in your application and makes it easy to overlay them or overlay into them as the kostenlps requires.
Another manifestation of the pop up is in the use of menu lists. Example presents a straightforward menu list with a selection of items to choose from. As in the other pop-up examples, selecting an item executes the code defined in the oncommand event handler for that item e. The menulist widget provides functionality beyond that of Blink>WindowDlalog regular menu. The menu list can be made editable when the user should be allowed to Handy dating kostenlos Blink>WindowDialog a value not represented in the menu items.
In this case, the menulist element definition in Example would change to something such as:. A Handy dating kostenlos Blink>WindowDialog value on the editable attribute allows input in the list. Input can be validated immediately by kostejlos the oninput attribute. The addition Handy dating kostenlos Blink>WindowDialog the onchange attribute can be used to carry out an extra script when a new selection is made.
Many options exist to display hierarchical information in your user interface. The most Best dating site in malta 02-0641 Tablet counting/filling machine King TB 4 (GMP) are tree-like and table-like structures, both of which are represented by elements in Mozilla's XPFE toolkit. In this section, we look at list boxes, trees, and grids.
With the exception of the tree, these elements are not limited in regard to the content they can contain. Currently, the tree only holds text and image content and grids are designed for holding the more diverse content as shown in upcoming examples.
Example shows a listbox widget with all the basic features, including the definition of the number of columns listcolthe listbox header listheadand a list item listitem. The first thing of note in the markup in Example is the rules for the nesting of elements within a listbox structure. Example has two columns. They are separated by a draggable grippy item, which also acts as a column separator in the header row.
The header is optional and has the same structure as a list item.
