| + | |
| − | Within the Attributes tab the attributes of the selected dataset can be
| + | |
| − | manipulated. The buttons New Column and Delete Column can be
| + | |
| − | used, when the dataset is in editing mode. At the moment only columns from
| + | |
| − | PostGIS layers can be edited, because this feature is not yet supported by
| + | |
| − | the OGR library.
| + | |
| − | | + | |
| − | <P>
| + | |
| − | The Toggle editing mode button toggles this mode.

| − | <P>
| + | |
| − | Within the Attributes tab you also find an <TT>edit widget</TT> and a
| + | |
| − | <TT>value</TT> column. These two columns can be used to define values or a range
| + | |
| − | of values that are allowed to be added to the specific attribute table columns.
| + | |
| − | They are used to produce different edit widgets in the attribute dialog. These
| + | |
| − | widgets are:
| + | |
| − | | + | |
| − | <P>
| + | |
| − | | + | |
| − | <UL>
| + | |
| − | <LI>line edit: an edit field which allows to enter simple text (or restrict to
| + | |
| − | numbers for numeric attributes).
| + | |
| − | </LI>
| + | |
| − | <LI>unique value: a list of unique attribute values of all pre-existing features
| + | |
| − | is produced and presented in a combo box for selection.
| + | |
| − | </LI>
| + | |
| − | <LI>unique value (editable): a combination of `line edit' and `unique value'.
| + | |
| − | The edit field completes entered values to the unique value, but also allows
| + | |
| − | to enter new values.
| + | |
| − | </LI>
| + | |
| − | <LI>value map: a combobox to select from a set of values specified in the
| + | |
| − | <TT>value</TT> column the Attributes tab. The possible values are
| + | |
| − | delimited by a semicolon (e.g. <code>high;medium;low</code>). It is also possible
| + | |
| − | to prepend a label to each value, which is delimited with an equal sign (e.g.
| + | |
| − | <code>high=1;medium=2;low=3</code>). The label is shown in the combobox instead of
| + | |
| − | the value.
| + | |
| − | </LI>
| + | |
| − | <LI>classification: if a unique value renderer is selected for the layer, the
| + | |
| − | values used for the classes are presented for selection in a combobox.
| + | |
| − | </LI>
| + | |
| − | <LI>range (editable): A edit field that allows to restrict numeric values to a
| + | |
| − | given range. That range is specified by entering minium and maximum value
| + | |
| − | delimited by a semicolon (e.g. <code>0;360</code>) in the <TT>value</TT> column of
| + | |
| − | the Attributes tab.
| + | |
| − | </LI>
| + | |
| − | <LI>range (slider): A slider widget is presented that allows selection of a value
| + | |
| − | in a given range and precision. The range is specifed by minimum, maximum
| + | |
| − | value and a step width (e.g. <code>0;360;10</code>) in the <TT>value</TT> column of
| + | |
| − | the Attributes tab.
| + | |
| − | </LI>
| + | |
| − | <LI>file name: the line edit widget is accompanied by a push button. When pressed
| + | |
| − | it allows to select a filename using the standard file dialog.
| + | |
| − | </LI>
| + | |
| − | </UL>
