QGIS Configuration

QGIS is highly configurable through the Settings menu. Choose between Panels, Toolbars, Project Properties, Options and Customization.


QGIS follows desktop guidelines for the location of options and project properties item. Consequently related to the OS you are using, location of some of items described above could be located in the View menu (Panels and Toolbars) or in Project for Options.

Panels and Toolbars

In the Panels‣ menu, you can switch on and off QGIS widgets. The Toolbars‣ menu provides the possibility to switch on and off icon groups in the QGIS toolbar (see figure_panels_toolbars).

Activating the QGIS Overview

In QGIS, you can use an overview panel that provides a full extent view of layers added to it. It can be selected under the menu nix Settings ‣ Panels or win View ‣ Panels. Within the view is a rectangle showing the current map extent. This allows you to quickly determine which area of the map you are currently viewing. Note that labels are not rendered to the map overview even if the layers in the map overview have been set up for labeling. If you click and drag the red rectangle in the overview that shows your current extent, the main map view will update accordingly.


Show Log Messages

It’s possible to track the QGIS messages. You can activate checkbox Log Messages in the menu nix Settings ‣ Panels or win View ‣ Panels and follow the messages that appear in the different tabs during loading and operation.

Свойства проекта

In the properties window for the project under nix Settings ‣ Project Properties (kde) or nix win Project ‣ Project Properties (Gnome), you can set project-specific options. These include:

  • In the General menu, the project title, selection and background color, layer units, precision, and the option to save relative paths to layers can be defined. If the CRS transformation is on, you can choose an ellipsoid for distance calculations. You can define the canvas units (only used when CRS transformation is disabled) and the precision of decimal places to use. You can also define a project scale list, which overrides the global predefined scales.
  • Вкладка Система координат позволяет выбрать систему координат для данного проекта и включить преобразование координат векторных и растровых слоёв «на лету», если используются слои с разными системами координат.

  • With the third Identify layers menu, you set (or disable) which layers will respond to the identify tool (see the “Map tools” paragraph from the Параметры section to enable identifying of multiple layers).
  • The Default Styles menu lets you control how new layers will be drawn when they do not have an existing .qml style defined. You can also set the default transparency level for new layers and whether symbols should have random colours assigned to them. There is also an additional section where you can define specific colors for the running project. You can find the added colors in the drop down menu of the color dialog window present in each renderer.
  • The tab OWS Server allows you to define information about the QGIS Server WMS and WFS capabilities, extent and CRS restrictions.
  • The Macros menu is used to edit Python macros for projects. Currently, only three macros are available: openProject(), saveProject() and closeProject().

Macro settings in QGIS

  • The Relations menu is used to define 1:n relations. The relations are defined in the project properties dialog. Once relations exist for a layer, a new user interface element in the form view (e.g. when identifying a feature and opening its form) will list the related entities. This provides a powerful way to express e.g. the inspection history on a length of pipeline or road segment. You can find out more about 1:n relations support in Section Creating one to many relations.


mActionOptions Some basic options for QGIS can be selected using the Options dialog. Select the menu option Settings ‣ mActionOptions Options. The tabs where you can customize your options are described below.

Владка «Общие»

Вкладка «Система»

Переменные среды

System environment variables can now be viewed, and many configured, in the Environment group (see figure_environment_variables). This is useful for platforms, such as Mac, where a GUI application does not necessarily inherit the user’s shell environment. It’s also useful for setting and viewing environment variables for the external tool sets controlled by the Processing toolbox (e.g., SAGA, GRASS), and for turning on debugging output for specific sections of the source code.

  • checkbox Use custom variables (restart required - include separators). You can [Add] and [Remove] variables. Already-defined environment variables are displayed in Current environment variables, and it’s possible to filter them by activating checkbox Show only QGIS-specific variables.

Вкладка «Источники данных»

Таблица атрибутов

  • checkbox Открывать таблицу аттрибутов во встраиваемом окне (требуется перезапуск)

  • checkbox Copy geometry in WKT representation from attribute table. When using mActionCopySelected Copy selected rows to clipboard from the Attribute table dialog, this has the result that the coordinates of points or vertices are also copied to the clipboard.
  • Attribute table behaviour selectstring. There are three possibilities: ‘Show all features’, ‘Show selected features’ and ‘Show features visible on map’.
  • Attribute table row cache selectnumber. This row cache makes it possible to save the last loaded N attribute rows so that working with the attribute table will be quicker. The cache will be deleted when closing the attribute table.
  • Representation for NULL values. Here, you can define a value for data fields containing a NULL value.

Источники данных

  • Scan for valid items in the browser dock selectstring. You can choose between ‘Check extension’ and ‘Check file contents’.
  • Scan for contents of compressed files (.zip) in browser dock selectstring. ‘No’, ‘Basic scan’ and ‘Full scan’ are possible.
  • Prompt for raster sublayers when opening. Some rasters support sublayers — they are called subdatasets in GDAL. An example is netCDF files — if there are many netCDF variables, GDAL sees every variable as a subdataset. The option allows you to control how to deal with sublayers when a file with sublayers is opened. You have the following choices:
    • ‘Always’: Always ask (if there are existing sublayers)
    • ‘If needed’: Ask if layer has no bands, but has sublayers
    • ‘Never’: Never prompt, will not load anything
    • ‘Load all’: Never prompt, but load all sublayers

Вкладка «Инструменты»

This menu offers some options regarding the behaviour of the Identify tool.

  • Search radius for identifying and displaying map tips is a tolerance factor expressed as a percentage of the map width. This means the identify tool will depict results as long as you click within this tolerance.
  • Highlight color allows you to choose with which color should features being identified are to be highlighted.
  • Buffer expressed as a percentage of the map width, determines a buffer distance to be rendered from the outline of the identify highlight.
  • Minimum width expressed as a percentage of the map width, determines how thick should the outline of a highlighted object be.

Excluding some URLs can be added to the text box below the proxy settings (see Figure_Network_Tab).

If you need more detailed information about the different proxy settings, please refer to the manual of the underlying QT library documentation at http://doc.trolltech.com/4.5/qnetworkproxy.html#ProxyType-enum.


Использование прокси-серверов

Using proxies can sometimes be tricky. It is useful to proceed by ‘trial and error’ with the above proxy types, to check to see if they succeed in your case.

You can modify the options according to your needs. Some of the changes may require a restart of QGIS before they will be effective.

  • nix Settings are saved in a text file: $HOME/.config/QGIS/QGIS2.conf
  • osx You can find your settings in: $HOME/Library/Preferences/org.qgis.qgis.plist
  • win Settings are stored in the registry under: HKEY\CURRENT_USER\Software\QGIS\qgis

Настройка интерфейса

The customization tool lets you (de)activate almost every element in the QGIS user interface. This can be very useful if you have a lot of plugins installed that you never use and that are filling your screen.

Figure Customization 1:


The Customization dialog nix

QGIS Customization is divided into five groups. In checkbox Menus, you can hide entries in the Menu bar. In checkbox Panels, you find the panel windows. Panel windows are applications that can be started and used as a floating, top-level window or embedded to the QGIS main window as a docked widget (see also Panels and Toolbars). In the checkbox Status Bar, features like the coordinate information can be deactivated. In checkbox Toolbars, you can (de)activate the toolbar icons of QGIS, and in checkbox Widgets, you can (de)activate dialogs as well as their buttons.

With mActionSelect Switch to catching widgets in main application, you can click on elements in QGIS that you want to be hidden and find the corresponding entry in Customization (see figure_customization). You can also save your various setups for different use cases as well. Before your changes are applied, you need to restart QGIS.
