gvSIG-Desktop 1.10. Nuevas funcionalidades
NavTable scrolls through the records and features in a friendly way. You will find the navigation bar at the bottom of NavTable's window.
With these buttons you can:
- Go to the first record
- Go to the previous record
- Go to the next record
- Go to the last record
- Go to any record using the box located between the buttons described above. It shows the number of the records you're currently viewing. If you enter a new value here you will see the corresponding record. Next to the position of the box there is a number indicating the total amount of records in the table.
If you are working in the central area of NavTable (click on any row) you can use the buttons “right”or “left”, “home” or “end” to change the record that you want to see.
Selecting elements
If you click on the checkbox "selected" the navigation buttons will work only for features that are previous selected. If a feature is selected, the bottom area of the NavTable Window will be highlighted in yellow. In between parentheses the number of selected records can be seen next to the whole number of records.
In this image you see an example explaining how this function works: record 8 for a layer with 20 records is displayed where 7 records are selected.
If the checkbox "selected" is activated without any selected feature, all records will be shown empty and the box will not display any number. and
.
The option "select" is another interesting tool you can find next to "selected" in the Nav Table menu. If you activate the checkbox next to "select", the attributes you are visualizing will be selected and highlighted in the view. In the case that other features were selected, this option will turn them unselected and will select only the register you are visualizing.
On top of the NavTable Window there is the button "Filter" . If you press it, a dialogue window will appear in which you can define exactly what you want to select (attributes and calculations). If you click on "clear selection"
all selections will be turned off and no features will be selected.
Zoom to feature
If you click on the zoom button 
the feature will be displayed in the center of the view, referring to the record you are working with at that time. The scale of the view will be changed to have a good visualization of the data. In case you are working with a point layer, a scale size will be chosen that allows to see also the surroundings of the point.
With help of the button "always zoom" next to the checkbox "select", Navtable will zoom to each feature referring to the record you are visualizing. If you click on "fixed scale" as well, Navtable will zoom to the feature and display it in the center of the view, but the scale will always remain the same. It is possible to change the scale value introducing a new one in the "scale bar" of gvSIG. This is shown on the buttom right of the gvSIG view, next to where the coordinates are displayed.
Tip: The options "always zoom" or "fixed scale" together with "select" is a very interesting way of navigate through the features of a layer.
