Outline View

Changed:

<
< Whenever the user selects a session variable in the [[http://herschel.esac.esa.int/hcss-doc-12.0/index.jsp#hcss_drm:herschel.ia.inspector.views.VariablesView][VariablesView]], a [[http://herschel.esac.esa.int/hcss-doc-12.0/index.jsp#hcss_drm:herschel.ia.gui.kernel.event.SelectionEvent][SelectionEvent]] is sent around.
The [[http://herschel.esac.esa.int/hcss-doc-12.0/index.jsp#hcss_drm:herschel.ia.inspector.views.OutlineView][OutlineView]] is listening to such event and it tries to find the appropriate component that can show the outline information of that variable.

The contract for outline components is:

Implement the [[http://herschel.esac.esa.int/hcss-doc-12.0/index.jsp#hcss_drm:herschel.ia.gui.apps.views.outline.OutlineComponent][OutlineComponent]] interface by extending a javax.swing.JComponent.

<
< The recommended way of implementing [[http://herschel.esac.esa.int/hcss-doc-12.0/index.jsp#hcss_drm:herschel.ia.gui.apps.views.outline.OutlineComponent][OutlineComponent]] is by extending ObjectOutline, which provides a table with basic information about the variable.

Methods getExtraTableInfo() and getExtraComponent() may be overriden as needed for providing extra information about your type.

For example, suppose you want to create an outline for FineTime variables to show their contents in the outline view whenever a session variable of that type is selected by the user.

Source Code of Basic implementations

Package herschel.ia.dataset.gui contains some basic implementations for OutlineComponents:

ArrayDataOutline: a simple outline for any array data
DatasetOutline: a simple outline for any dataset
ProductOutline: a simple outline for any product

Package herschel.ia.dataset.gui contains some basic implementations for OutlineComponent objects:

ArrayDataOutline: a simple outline for any array data
CompositeDatasetOutline: a simple outline for any dataset
ProductOutline: a simple outline for any product

__init__.py: how the above get registered

Changed:

<
< If you have a sub-class of e.g. a product, you can also create a dedicated OutlineComponent for that sub-class, which will be picked up instead of the default ProductOutline.

A special kind of outline is devoted to show previews of FITS files (for images, cubes, spectra...).

Changed:

<
< This is managed by FitsFileOutline, which reads the product contained in the FITS file in the background, and shows an image preview for it when done.

For this to work properly, any type that is meaningful to produce a preview should:

Changed:

<
< 1. Extend herschel.ia.gui.kernel.PreviewMaker. For example, for images (herschel.ia.gui.image.Image):

You may have created an implementation of the former Explorer interface which is used by the dataset inspector (and is registered within that inspector).

Changed:

<
< If you do not expect that your explorer needs to talk to other parts within the HIPE application, you can simply extend ia.dataset.gui.views.AbstractExplorerComponent:
