ordinal position, drag and drop</title><prolog><metadata><keywords/></metadata></prolog><conbody>
<section><title>Description</title> <p> <filepath>Ordinal</filepath> uses
five numbered, draggable windows, similar to the draggable window used in
the previous example to demonstrate the ordinal positioning of windows. </p> </section>

<section><title>Running on the emulator</title> <p>Clicking in a window with
the left mouse button brings that window to the front by giving it an ordinal
position of 0. Dragging with the left mouse button moves the windows around
on the screen. </p> <p>Clicking in a window with the right mouse button cascades
the children of that window in the top left corner (using <codeph>RWindowTreeNode::Child()</codeph>, <codeph>NextSibling()</codeph> and <codeph>PrevSibling()</codeph>). The windows are cascaded according to their ordinal position in the top
window's list of siblings. </p> </section>
<section><title>Running on the target phone</title> <p>The behaviour invoked
by the right mouse button click is unavailable on the target phone. Windows
can be dragged using the pointer, and tapping on a window brings it to the
front. </p> </section>
