78. Portable view¶

78.1. Introduction

The Portable View extension lets you work with a new document that is a view with basic query options in which the rest of tools has been removed. With this you can convert a view in portable view and vice versa.

Besides, you can also package this portable view as a gvSIG complement. The generated gvSIG package contains both the generated data (files) and the portable view configuration. Using the complement manager, another user can install that portable view in his gvSIG.

Therefore, this extension has two main uses:

Have available a query view.
Allow portability/distribution of a gvSIG View containing all associated information (legends, labeling, map scales…)

The “Portable View: editor” y “Portable View: viewer” extensions are installed using the complement manager “Administrador de complementos”.
