Main window

Catalog(s)

The large right-central part of the Main window may show one or more Catalogs.

A Catalog provides an overview of:

the ILWIS objects in a directory,
the raster maps that are available in a map list,
the objects that are available in an object-collection.

Objects and icons:

The ILWIS object types and their icons that can be shown in a Catalog are:

	raster maps
	polygon maps
	segment maps
	point maps
	tables
	map lists
	object collections
	map views
	layouts
	annotation text objects
	domains
	representations
	georeferences
	coordinates systems

	histograms of raster maps
	histograms of polygon maps
	histograms of segment maps
	histograms of point maps
	sample sets
	two-dimensional tables
	matrices
	(user-defined) filters
	user-defined functions
	scripts

Also drives and directories can be shown. To see foreign file types in a Catalog, i.e. files with non-ILWIS extensions, use the Customize Catalog, Object Selection tab.

To get Help on a certain object type, click the object in a Catalog with the right mouse button, and choose Help from the context-sensitive menu.

List View and Details View:

In ILWIS 3, you can choose to see the objects in a Catalog listed in:

List View: simple list of object names and icons,
Details View: detailed information for each object.

You can use the List and the Details commands on the View menu of the Main window, but you can also use the List button or the Details button in the standard toolbar of the Main window.

Visible object types, sorting objects, querying for objects:

Furthermore, in each Catalog, you can specify:

the visible object types,

see Catalog - Show, Main window : object selection toolbar or Customize Catalog, Object Selection tab,

the sorting method of objects,

see Catalog - Sort By or Details View,

a query to search for specific objects,

see Catalog - Queries or Customize Catalog, Query tab.

For more information, see also the List View and Details View topics.

Multiple Catalogs:

To open another new Catalog, you can choose the New Catalog command from the Window menu in the Main window, or click the New Catalog button in the standard toolbar of the Main window. Multiple Catalogs may give you a better overview of your data in several directories or in several object collections, etc. You can also easily copy objects from one Catalog (directory, object collection) to another by dragging.

Using a Catalog:

A Catalog is mainly used for the following actions:

move the mouse pointer over an object in a Catalog:
the status bar displays the description of that object, and whether an object is dependent (D), calculated (C) and/or up-to-date (U);
double-click an object in a Catalog:
the object is opened and displayed in a new window; if you open a dependent object which has not been calculated yet, the object will first be calculated;
click the right mouse button on an object in a Catalog:
a context-sensitive menu appears from which you can choose a command or an operation,
drag one or more raster, polygon, segment or point maps from a Catalog to a map window or to a pixel information window:
the object(s) are added to that map window or that pixel info window,
drag a compatible georeference or coordinate system from a Catalog to a map window which does not have a raster map yet:
the map window will temporarily use that georeference or coordinate system;
drag a compatible coordinate system from a Catalog to a pixel info window:
the coordinate system will be added to the pixel info window; you can thus read coordinates in the new coordinate system as well;
drag one or more objects from one Catalog to another:
the selected objects are copied to the other Catalog;
drag a map or table from a Catalog to an operation in the Operation-tree or the Operation-list:
the dialog box of that operation is opened and the input map or table name already filled out;
drag a map or table from a Catalog to a drop-down list box in a dialog box of an operation:
the object is filled out in the field of the dialog box.

Other functionality:

To refresh the contents of a Catalog, choose the Refresh command from the Window menu, or press the F5 key on the keyboard.
To arrange Catalogs, choose the Arrange Catalogs command from the Window menu.
To close all Catalogs, choose the Close All Catalogs command from the Window menu.

The settings of each Catalog are stored in the registry when a Catalog is closed.
