Employment/Purpose

The box model of XUL is used to divide a portion of the display into a series of boxes. Components inside of a box will orient themselves horizontally or vertically. By combining a series of boxes and separators, you can control the layout of the visual presentation.

A box can lay out its children in one of two orientations, either horizontally or vertically. A horizontal box lines up its components horizontally and a vertical box orients its components vertically. You can think of a box as one row or one column from an HTML table.

Example

 <zk>
     <box orient="vertical">
         <button label="Button 1"/>
         <button label="Button 2"/>
     </box>
     <box  orient="horizontal">
         <button label="Button 3"/>
         <button label="Button 4"/>
     </box>

Cell Component

In ZK5, we have introduced a new component named Cell which can be embedded into a Grid or Box (Hbox and Vbox) to fully control the layout and the style. You can now use the rowspan or the colspan property to layout your Grid, for example a content cell can now cross over multiple rows. The code below demonstrates how to do this:

<box>
    <cell sclass="years">
        ...
    </cell>
</box>
