// description:
|
|
// Provides Delphi-style panel layout semantics.
|
|
//
|
|
// A LayoutContainer is a box with a specified size (like style="width: 500px; height: 500px;"),
|
|
// that contains children widgets marked with "layoutAlign" of "left", "right", "bottom", "top", and "client".
|
|
// It takes it's children marked as left/top/bottom/right, and lays them out along the edges of the box,
|
|
// and then it takes the child marked "client" and puts it into the remaining space in the middle.
|
|
//
|
|
// Left/right positioning is similar to CSS's "float: left" and "float: right",
|
|
// and top/bottom positioning would be similar to "float: top" and "float: bottom", if there were such
|
|
// CSS.
|
|
//
|
|
// Note that there can only be one client element, but there can be multiple left, right, top,
|
|
// or bottom elements.
|
|
//
|
|
// See `LayoutContainer.ChildWidgetProperties` for details on the properties that can be set on
|
|
// children of a `LayoutContainer`.
|
|
//
|
|
// example:
|
|
// | <style>
|
|
// | html, body{ height: 100%; width: 100%; }
|
|
// | </style>
|
|
// | <div data-dojo-type="dijit/layout/LayoutContainer" style="width: 100%; height: 100%">
|
|
// | <div data-dojo-type="dijit/layout/ContentPane" data-dojo-props="layoutAlign: 'top'">header text</div>
|
|
// | <div data-dojo-type="dijit/layout/ContentPane" data-dojo-props="layoutAlign: 'left'" style="width: 200px;">table of contents</div>
|
|
// | <div data-dojo-type="dijit/layout/ContentPane" data-dojo-props="layoutAlign: 'client'">client area</div>
|
|
// | </div>
|
|
//
|
|
// Lays out each child in the natural order the children occur in.
|
|
// Basically each child is laid out into the "remaining space", where "remaining space" is initially
|
|
// the content area of this widget, but is reduced to a smaller rectangle each time a child is added.
