XUL_教程/工具栏

工具栏通常沿着窗口顶部放置，并包含许多完成普通功能的按钮。XUL有一个创建工具栏的方法。

A toolbar is usually placed along the top of a window and contains a number of buttons that perform common functions. XUL has a method to create toolbars.

工具栏

Like a number of elements, XUL toolbars are a type of box.像许多的界面要素， XUL工具栏也是一种界面框。 Usually, a row of buttons would appear in the toolbar, but any element can be placed in a toolbar.通常，工具栏里会出现一排按钮，但任何界面要素都可以放到工具栏里。 For example, the Mozilla browser window contains a textbox that displays the page URL.举例来说， mozilla浏览器窗口包含一个文本框 ，显示了该网页的url 。

Toolbars may be placed on any side of the window, either horizontally or vertically.工具栏可被水平或垂直地放置在窗口的任一边。 Of course you wouldn't normally put a textbox in a vertical toolbar.当然，通常你不会把文本框放在一个垂直工具栏里。 Actually, because toolbars are just boxes they can actually go anywhere you want, even in the middle of a window.事实上，因为工具栏只是个界面框，它们能去你想要它们去的任何地方，即使是窗口的中间。 Typically however, a set of toolbars would appear along the top of a window.通常，一组工具栏会出现在窗口的顶部。 When more than one toolbar is placed next to each other, they are typically grouped together in something called a 'toolbox'.当多个工具栏一个接一个放置时，他们通常被一个叫做'工具箱'的东西集合在一起。 [ edit ] A simple toolbar inside a toolbox [编辑] 一个简单的工具栏里面一个工具箱

Adding a Toolbar

Like a number of elements, XUL toolbars are a type of box. Usually, a row of buttons would appear in the toolbar, but any element can be placed in a toolbar. For example, the Mozilla browser window contains a textbox that displays the page URL.

Toolbars may be placed on any side of the window, either horizontally or vertically. Of course you wouldn't normally put a textbox in a vertical toolbar. Actually, because toolbars are just boxes they can actually go anywhere you want, even in the middle of a window. Typically however, a set of toolbars would appear along the top of a window. When more than one toolbar is placed next to each other, they are typically grouped together in something called a 'toolbox'.

A simple toolbar inside a toolbox

<toolbox>
  <toolbar id="nav-toolbar">
    <toolbarbutton label="Back"/>
    <toolbarbutton label="Forward"/>
  </toolbar>
</toolbox>

This has created a toolbar containing two buttons, a Back button and a Forward button. The one toolbar has been placed inside the toolbox. This has involved four new tags, which are described here.

Our find files example

Let's add a toolbar to the find files dialog. We don't really need one but we'll add one anyway to demonstrate its use. Two buttons will be added, an Open button and a Save button. Presumably, they would allow the user to save search results and re-open them later.

<vbox flex="1">
  <toolbox>
    <toolbar id="findfiles-toolbar">
      <toolbarbutton id="opensearch" label="Open"/>
      <toolbarbutton id="savesearch" label="Save"/>
    </toolbar>
  </toolbox>
  <tabbox>

 

A toolbar with two buttons has been added here. In the image, you can see them appear horizontally along the top. Notice that the toolbar has been placed inside the vertical box just above the tabbox. This is because we need the vertical orientation so that the toolbar will appear above everything else.
