Navigatorul QGIS

QGIS Browser is available as a standalone application and as a panel in QGIS Desktop. It lets you easily navigate in your filesystem and manage geodata. You can have access to common vector files (e.g., ESRI shapefiles or MapInfo files), databases (e.g., PostGIS, Oracle, SpatiaLite or MS SQL Spatial) and OWS/WCS|WMS|WFS connections. You can also view your GRASS data (to get the data into QGIS, see Integrarea GRASS GIS).

Controlul grafic al Navigatorului QGIS

To activate QGIS Browser, right-click on QGIS toolbar and check checkbox Browser Panel or select it from View ‣ Panels or Settings ‣ Panels (kde). In the Browser panel, you can now browse in your filesystem, databases and web services and get your data into the map view with a simple drag-and-drop or double-click.

You can also open a QGIS project directly from the Browser panel by double-clicking its name or by drag-and-drop into the map view.

În partea de sus a panoului, veți găsi câteva pictograme care vă pot ajuta:

  • addLayer Add Selected Layers. You can also add data into the map view by selecting Add Layer or Add selected layers in the context menu.

  • draw Actualizează arborele navigatorului

  • filterMap search for specific data. Enter a search word or wildcard and the browser will filter the tree to only show paths to matching DB tables, filenames or folders – other data or folders won’t be displayed. See the Browser Panel(2) example on the figure_browser_panels. The comparison can be case-sensitive or not. It can also be set to:
    • normal: return any item containing the search text
    • using wildcard(s): fine tune the search using ? and/or * characters to specify the position of the search text

    • utilizând o expresie regulată

  • collapseTree Restrânge întregul arbore

  • propertiesWidget Enable and disable properties widget. When toggled on, a new widget is added at the bottom of the panel showing, if applicable, metadatas of the selected item

Right-click an item in the browser tree helps you to:

  • in case of file or table, display its metadata or open it in your project. Tables can even be renamed, deleted or truncated
  • in case of folder, bookmark it into your favourites, hide it from the browser tree. Hidden folders can be managed from the Settings ‣ Options ‣ Data Sources tab

  • actualizare, redenumire și ștergere schemă.

De asemenea, puteți importa fișierele în baze de date, sau să copiați tabelele dintr-o schemă/bază de date într-alta, printr-o simplă glisare. Pentru a evita defilarea îndelungată pe durata glisării, este disponibil un al doilea panou în navigator. Este suficient să selectați fișierul și să-l glisați de la un panou la altul.

It’s also possible to run the QGIS Browser as a standalone application. Like the Browser panel, the standalone Browser helps you navigate through your filesystem and manage your geodata. It also helps you preview or create them and open them in a QGIS project by drag-and-drop.

Startați navigatorul QGIS

  • nix Introduceți “qbrowser” în linia de comandă.

  • win Startați Navigatorul QGIS folosind meniul Start sau scurtăturile de pe desktop.

In figure_browser_standalone_metadata, you can see the enhanced functionality of the standalone QGIS Browser. The Param tab provides the details of your connection-based datasets, like PostGIS or MSSQL Spatial. The Metadata tab contains general information about the file (see vectormetadatamenu). With the Preview tab, you can have a look at your files without importing them into your QGIS project. It’s also possible to preview the attributes of your files in the Attributes tab.
