Attribute Table

-The Attribute Table dialog displays the rows and columns from the selected -layer. From this dialog you can view, edit, and search attributes. +

Attribute table

+The attribute table displays features of a selected layer. Each row in the table represents one map +feature with its attributes shown in several columns. The features in the table can be searched, +selected, moved or even edited. +By default the attribute table is a separate window. If you opened it and cannot see anymore, it is most likeny under the main QGIS window. You can make it also a docked window, by stetting in .

+ +The number of table features is printed on its header.

Selecting

+ +Rows can be selected by clicking on the row number on the left side of the row. Selecting a row +doesn't change the current cursor position. Multiple rows can be marked by holding the + key.
+A continuous selection can be made by holding the key and clicking on several row headers +on the left side of the rows. All rows between the current cursor position and the clicked row are +selected. + + +

Sorting

+ +Each column can be sorted by clicking on its column header. A small arrow indicates the sort order +(downward pointing means descending values from the top row down, upward pointing means +ascending values from the top rown down).
+Use button to sort selected rows and display them in first table rows. +To show selected records only, use the checkbox . + + +

Searching

+ +For a simple search by attributes on only one column the field can be used. Select +the field (column) from which the search should be performed from the dropdown menu and hit the + button.
+For more complex searches use the . This button opens the Query Builder and allows you to define a subset of a table using a SQL-like WHERE clause, display the result in the main window and save it as a Shapefile. + + +

Field Calculator

+ +The button in the attribute table allows to perform calculations on basis of +existing attribute values or defined functions, e.g. to calculate length or area of geometry features.
+The results can be written to a new attribute column or it can be used to update values in an already +existing column.
+You have to bring the vector layer in editing mode, before you can click on the icon to +open the dialog. + diff --git a/resources/context_help/QgsIdentifyResults-en_US b/resources/context_help/QgsIdentifyResults-en_US index 9f1b8478109..a113ba1605a 100644 --- a/resources/context_help/QgsIdentifyResults-en_US +++ b/resources/context_help/QgsIdentifyResults-en_US @@ -1,8 +1,10 @@

Identify Features

The results dialog shows all the features identified within the search tolerance. -To see the results, expand the feature information by clicking on the plus sign to the left of each feature. +To see the results details, expand the feature information on the left of each feature.

Open Vector Layer Dialog

The open vector layer dialog is used to add vector data to the QGIS map view. Vector data are spatial data described using geometries of points, lines and polygons (enclosed areas).

+QGIS supports vector data in a number of formats, including those supported by the OGR library data provider plugin, such as ESRI shapefiles, MapInfo MIF (interchange format) and MapInfo TAB (native format).

+QGIS supports PostGIS layers in a PostgreSQL database and SpatialLite layers. Support for additional data types (eg. delimited text) is provided by additional data provider plugins. A list of OGR supported vector formats incan be found in Appendix A.1 of the User Guide.

+Detailed description how to proceed with vector data is described in chapter 5 'Working with Vector Data'.
