|
|
// A BorderContainer is a box with a specified size (like style="width: 500px; height: 500px;"),
|
|
// that contains a child widget marked region="center" and optionally children widgets marked
|
|
// region equal to "top", "bottom", "leading", "trailing", "left" or "right".
|
|
// Children along the edges will be laid out according to width or height dimensions. The remaining
|
|
// space is designated for the center region.
|
|
// The outer size must be specified on the BorderContainer node. Width must be specified for the sides
|
|
// and height for the top and bottom, respectively. No dimensions should be specified on the center;
|
|
// it will fill the remaining space. Regions named "leading" and "trailing" may be used just like
|
|
// "left" and "right" except that they will be reversed in right-to-left environments.
|
|
// Optional splitters may be specified on the edge widgets only to make them resizable by the user.
|
|
//
|
|
// example:
|
|
// | <style>
|
|
// | html, body { height: 100%; width: 100%; }
|
|
// | </style>
|
|
// | <div dojoType="BorderContainer" design="sidebar" style="width: 100%; height: 100%">
