Use the show/hide buttons below to show and hide two simple panels. The first panel is created based on markup on the page and its
draggable configuration is set to
true; it can be dragged around the screen.
The Panel Control is an extension of Overlay that is meant to behave similarly to an OS window. Unlike true browser popup windows, Panel Control instances are floating DHTML elements embedded directly within the page context. The Panel Control extends the functionality of Overlay, adding support for modality, drag and drop, and close/dismiss buttons. Panel includes a pre-defined stylesheet to support the default look and feel characteristics that you see on this page.
In this tutorial, we will build two Panels. One of them will be based on existing markup; the other will be created dynamically using script. We'll pass configuration properties via the constructor to specify any non-default settings we want to use in our Panel instances.
These Panels introduce a few configuration properties. The
constraintoviewport property, when set to true, will keep the Panel from being positioned outside of the viewport; this defends against the panel being dragged out of the viewport by the user and against the panel being moved outside the viewport by scripted changes to its x/y properties. The
draggable property determines whether the Panel can be dragged (be sure to include the Drag and Drop Utility if you want your panel to be draggable), and the
close property determines whether the close icon should be displayed in the header of the Panel.
The markup for
panel1 is in standard module format, as is required by the Module and Overlay classes on which Panel is built. We also provide buttons to allow for easy showing and hiding of both Panels:
Note: Logging and debugging is currently turned off for this example.
