<hscrollbar>

A scrollbar manipulates the x or y position of a target view that is clipped by its parent, creating a scrolling effect when the user clicks up/down arrows, clicks on the scroll track or drags the thumb.

This tag creates a horizontal scrollbar. If you do not specify a scrolltarget the scrollbar will automatically be aligned to the bottom and size its width to its parent's width. It is expected that the parent view be smaller than the scrolltarget and set clip=true. The scrolling effect is produced by moving the scrolltarget while its visible region is clipped by the parent view.

If you would like the target view to start scrolled, simply set its x position to a negative number. For example, x=-10 will cause the view to be scrolled 10 pixels.

Note: If you have no vertical scrollbars in your application, using the <hscrollbar> tag will make the applications slightly smaller than if you were to use <scrollbar axis="x">.

Example 1. Simple scrollbar

<canvas height="100">
  <view name="main" width="100" height="90" clip="true">
    <view name="contents">
      <text width="200"  height="70" multiline="true" >
       Remember not only to say the right thing in the right place,
       but far more difficult still, to leave unsaid the wrong thing
       at the tempting moment.
        -- Benjamin Franklin
      </text>
    </view>
    <hscrollbar/>
  </view>
</canvas>

In the example above, the scrolltarget is the 'contents' view. A scrollbar moves its scrolltarget along its axis. The attribute that is controlled by the scrollbar may be specified as the scrollattr, overriding the default value of x or y.
