QGIS a fost conceput cu o arhitectură de plugin. Acest lucru permite adăugarea ușoară a multor caracteristici și funcții noi. Multe dintre caracteristicile din QGIS sunt de fapt implementate ca plugin-uri.
Plugin-urile QGIS sunt implementate fie ca Plugin-uri de Bază, fie ca Plugin-uri Externe.
Core Plugins are maintained by the QGIS Development Team and are automatically part of every QGIS distribution. They are written in one of two languages: C++ or Python.
Most of External Plugins are currently written in Python. They are stored either in the «Official» QGIS Repository at https://plugins.qgis.org/plugins/ or in external repositories and are maintained by the individual authors. Detailed documentation about the usage, minimum QGIS version, home page, authors,and other important information are provided for the plugins in the Official repository. For other external repositories, documentation might be available with the external plugins themselves. External plugins documentation is not included in this manual.
To install or activate a plugin, go to .
Installed external python plugins are placed under the
folder of the active user profile path.
Paths to Custom C++ plugins libraries can also be added under.
According to the plugin manager settings, QGIS main interface can display an icon on the right of the status bar to inform you that there are updates for your installed plugins or new plugins available.
The tabs in the Plugins dialog allow the user to install, uninstall and upgrade plugins in different ways. Each plugin has some metadata displayed in the right panel:
informații despre caracterul experimental al plugin-ului
vot(urile) de evaluare (se poate vota pentru plugin-ul preferat!)
unele link-uri utile, ca pagina de start, cea a actualizărilor și a depozitului de cod
Verificare actualizare la start. Ori de câte ori un nou plugin sau o actualizare de plugin este disponibilă, QGIS vă va informa «de fiecare dată când se lansează QGIS», «o dată pe zi», «o dată la 3 zile», «în fiecare săptămână», «la fiecare 2 săptămâni» sau «în fiecare lună».
Show also deprecated plugins. Because they use functions that are no longer available in QGIS, these plugins are set deprecated and generally unsuitable for production use. They appear among invalid plugins list.
By default, QGIS provides you with its official plugin repository with the URL
https://plugins.qgis.org/plugins/plugins.xml?qgis=3.0 (in case of QGIS 3.0)
in the Plugin repositories section. To add external author repositories,
click Add… and fill in the Repository Details form with a
name and the URL. The URL can be of
file:// protocol type.
The default QGIS repository is an open repository and you don’t need any authentication to access it. You can however deploy your own plugin repository and require an authentication (basic authentication, PKI). You can get more information on QGIS authentication support in Autentificarea chapter.
If you do not want one or more of the added repositories, they can be disabled from the Settings tab via the Edit… button, or completely removed with the Delete button.
In the All tab, all the available plugins are listed, including both core and external plugins. Use Upgrade All to look for new versions of the plugins. Furthermore, you can use Install Plugin if a plugin is listed but not installed, Uninstall Plugin as well as Reinstall Plugin if a plugin is installed. An installed plugin can be temporarily de/activated using the checkbox.
In the Installed tab, you’ll find listed the Core plugins, that you can not uninstall. You can extend this list with external plugins that can be uninstalled and reinstalled any time, using the Uninstall Plugin and Reinstall Plugin buttons. You can Upgrade All the plugins here as well.
The Upgradeable and New tabs are enabled when new plugins are added to the repository or a new version of an installed plugin is released. If you activated Show also experimental plugins in the Settings menu, those also appear in the list giving you opportunity to early test upcoming tools.
Installation can be done with the Install Plugin, Upgrade Plugin or Upgrade All buttons.
The Invalid tab lists all installed plugins that are currently broken for any reason (missing dependency, errors while loading, incompatible functions with QGIS version…). You can try the Reinstall Plugin button to fix an invalidated plugin but most of the times the fix will be elsewhere (install some libraries, look for another compatible plugin or help to upgrade the broken one).
