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


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).

Figure Panels and Toolbars:


パネルとツールバーメニュー nix



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 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.



It’s possible to track the QGIS messages. You can activate checkboxLog Messages in the menu Settings ‣ Panels and follow the messages in the General and Plugin tab during loading and operation.


In the properties window for the project under nix Project ‣ Project Properties or win Project ‣ Project Properties you 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 also can define a project scale list, that overrides the global predefined scales.
  • The CRS menu enables you to choose the Coordinate Reference System for this project, and to enable on-the-fly re-projection of raster and vector layers when displaying layers from a different CRS.
  • 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 オプション section to enable identifying of multiple layers.)
  • The menu Default Styles 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.
  • The tab OWS Server allows to define information about the QGIS Server WMS and WFS Capabilities, the Extent and the CRS Restrictions.
  • The menu Macros is to create a Python module, saved into a project.qgs file to be loaded and have specific functions run on the following project events: openProject(), saveProject() and closeProject().

  • Enable macros selectstring. This option was created to handle macros which are written to perform an action

on project events. You can chosse between ‘Never’, ‘Ask’, ‘For this session only’ and ‘Always (not recommended)’.



System environment variables can now be viewed and many configured in the Environment menu (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/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. Current environment variables ‣ are displayed below and it’s possible to checkbox Show only QGIS-specific variables.

Figure System Environment:




  • Add or Remove Path(s) to search for additional C++ plugin libraries



  • checkbox :guilabel:`ドックウィンドウで属性テーブルを開く(QGISの再起動が必要)’

  • 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 is to control how to deal with sublayers when a file with sublayers is opened. You have the following choices:
    • ‘常に’:毎回確認 (サブレイヤが存在する場合)

    • ‘必要な場合’:バンドがなくサブレイヤをもつかを尋ねます

    • ‘利用しない’:確認せず何もロードしません

    • ‘‘すべてをロード’:確認せず、すべてのサブレイヤをロードします

Here you find a list of predefined scales. With the ‘+’ and ‘-‘ buttons you can add or remove your individual scales.



  • checkbox Suppress attributes pop-up windows after each created feature
  • checkbox Reuse last entered attribute values
  • Validate geometries. Editing complex lines/polygons with many nodes can end up with very slow rendering. This is because the default validation procedures in QGIS can use a lot of time. To speed up rendering it is possible to select GEOS geometry validation (starting from GEOS 3.3) or to switch it off. GEOS geometry validation is much faster, but the disadvantage is that only the first geometry problem will be reported.


  • Define Rubberband Line width and Line color


  • checkbox Open snapping options in a dock window (QGIS restart required)
  • Define Default snap mode selectstring (‘To vertex’, ‘To segment’, ‘To vertex and segment’, ‘Off’)

  • Join style for curve offset
  • Quadrant segments for curve offset
  • Miter limit for curve offset


GDAL is a data exchange library for raster files. In this tab you can Edit create options and Edit Pyramids Options of the raster formats. Define which GDAL driver to be used for a raster format as in some cases more than one GDAL driver is available.



  • checkbox Automatically enable ‘on the fly’ reprojection if layers have different CRS

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.




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/qgis.conf
  • osx $HOME/Library/Preferences/org.qgis.qgis.plist で設定を見つけることができます。

  • win の設定では以下のレジストリに保存されます:HKEY\CURRENT_USER\Software\QGIS\qgis


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

Figure Customization 1:


カスタマイゼーションダイアログ nix

QGIS Customization is divided into five groups. In checkbox Menus you can hide entries in the Menu bar. In checkbox Panel 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 パネルとツールバー). 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 you want to be hidden and find the corresponding entry in Customization (see figure_customization). You can also save your various different setups for different use cases as well. Before your changes are applied, you need to restart QGIS.
