Description

The class of basic user panes. This is the class that gets subclassed by define pane.

You specify where on the screen the pane is to be displayed using the region: init-keyword. The region specified should be relative to the top left corner of the pane's parent, since the pane must be displayed within the confines of its parent.

If you wish the location of the pane to be transformed in some way, use the transform: init-keyword.

If you wish to use a port other than the default port, use the port: init-keyword.

You can specify the appearance for text in the pane using the style-descriptor: init-keyword.

The help-source: and help-context: keywords let you specify pointers to valid information available in any online help you supply with your application. The help-context: keyword should specify a context-ID present in the online help. This context-ID identifies the help topic that is applicable to the current pane. The help-source: init-keyword identifies the source file in which the help topic identified by help-context: can be found. A list of context-IDs should be provided by the author of the online help system.
