Morph Layout
The Morph layout uses the <morph> element to create a dialog box that dynamically adjusts the layout of its contents. This makes the Morph layout very useful for displaying a dialog box with an varying set of controls based on context or containing a large number of controls.
Consider a dialog box with a Morph layout that initially displays its contents in the same manner as a Grid layout:
A dialog box with a Morph layout with a single column of label and related textbox controls.
As the dialog box is resized, the layout may change to include additional columns. For example:
A dialog box with a Morph layout with two columns of label and related textbox controls.
When the dialog box is resized so small that all of the elements can no longer be displayed, the layout changes to a tabbed box. For example:
A dialog box with a Morph layout with tabs, each with a single column of label and related textbox controls.
This Morph dialog box is described in XML as follows:
<?xml version="1.0" encoding="utf-8"?>
