Example 5.7. Example for the use of a renderer class

Renderer classes can be used to display the content of document fields in columns of the Explorer window, Query window and Resource chooser window. The predefined renderers are listed in the next table. For own renderer classes, you need to extent the class hox.corem.editor.toolkit.table.columnrenderer.LayoutColumnRenderer.

Class	Description
GenericPropertyLayoutColumnRenderer	Combines the ImageLayoutColumnRenderer, LinkListPropertyLayoutColumnRenderer, SgmlTextPropertyLayoutColumnRenderer and StringPropertyLayoutColumnRenderer.
StringPropertyLayoutColumnRenderer	Usable for string, integer, Boolean and date fields. Displays plain text.
SgmlTextPropertyLayoutColumnRenderer	Usable for `SgmlText` fields. With the attribute `displayLength`, you can define the maximum length of the text to display. Default is "80".
BlobPropertyLayoutColumnRenderer	Usable for BlobProperty fields. The size of the blob in KB is shown.
ImageLayoutColumnRenderer	Usable for images of type `.jpeg` and `.gif` up to 10kB size. The width and height (in pixel) of the image can be defined with the attributes `width` and `height`.
LinkListPropertyLayoutColumnRenderer	Usable for LinkList fields. Two modes can be applied, using the attribute `displaySummary`. "True" (the default) will only show the number of links contained in the LinkList field. "False" will display one or more links included in the field. You can define the maximum number of shown links using the attribute `noRenderedLinks` (default is "1"). If you choose "0", all links will be shown.
DisplacementColumnRenderer	Shows the displacement status of a document.
ImpliedPropertyLayoutColumnRenderer	Usable for implied properties of the document (see the table in this chapter above). Display the property as plain text and optionally a state or document type icon using the attributes `displayStateIcon` and `displayTypeIcon` respectively. If you choose both icons to show, only the state icon will be displayed.
