You can now see the full path for the QGIS project file in the project properties dialog.
Now when you are measuring areas and distances, you can remove unwanted vertices from your measurement line using the delete or backspace keys.
We have made a number of improvements to the editor widgets:
new edit widget for date/time capable of setting null dates
filter line edit
Proper handling of NULL values for edit widgets
Photo widget preserves NULL value
Web widget preserves NULL value
Attribute table can distinguish between 0 and NULL
Add suffix support for range widget
You can now use just a subset of related fields when creating a vector join.
Sometimes you want to have an attribute that is calculated and that is always „fresh“ - reflecting the current state of the feature properties. Now you can add virtual fields to your table which are based on an expression.
When creating a custom action for a vector layer, you can now define an icon to be used for the action too.
+ for string concatenation.
attribute( feature, attribute_name ) - gets the
specified attribute from a feature.
$currentfeature - returns the current feature.
$atlasfeature - returns the atlas feature.
getFeature - gets a matching feature from a layer.
You can now choose to disable certain classes in graduated and categorised renderers without actually removing them.
The second phase of the legend / table of contents overhaul has been completed. This includes:
API cleanup (for developers)
Visibility groups of map layers in layer tree. This new toolbar button allows quick changes between the groups of layers that should be visible.
Ability to manage layer groups from the legend toolbar
The new legend filter option on the legend toolbar will remove legend items for any classes which are not currently in the view extent. This is an awesome improvement as it ensures that your map legend does not contain entries for items not currently in the map view. It is available in the main map legend and in map composer and for WMS layers.
Rule-based renderer legends can now be displayed in a pseudo-tree
tree view and attribute selection for layer assigment in dialog
support fill polygons/HATCH
represent texts as MTEXT instead of TEXT (including font, slant and weight)
support for RGB colors when there’s no exact color match
use AutoCAD 2000 DXF (R15) instead of R12
remove R18 test methods
We have added a checkbox and data defined button for controlling whether an item is excluded from composer exports/printouts. If the item is unchecked it will be visible at composition design time only.
For table or HTML frames, a checkbox now controls whether the containing page should be exported when the frame is empty.
The item tree panel in the map composer allows for selection of items, hiding/showing items, toggling lock status of items and double-clicking to edit item id. You can also use drag and drop to reorder items.
Lines can be styled using line symbol style dialog
Arrow head fill and outline colors can be user defined
Arrow head outline width can be user defined
Many properties of composer items can now be controlled using data binding. These include:
Transparency and blend mode.
Map scale, extents and rotation.
Atlas feature margin.
Item size and position.
Page size, orientation and number of pages.
Picture items in the map composer now support remote urls as a picture source. This source can also be data defined.
Теперь Вы можете установить заголовок таблицы и цвет шрифта содержимого.
Tables can now be split across multiple frames, allowing their content to be distributed over columns or over different pages.
Added option show headers on first frame, all frames, or no frames.
Allow manual control of column widths.
New options for table source, including current atlas feature and child features from a relation.
Choice of behaviour for empty tables, include hiding the entire table, showing empty cells, or displaying a set message in the table body.
Added a checkbox to filter table features to those which intersect the current atlas feature.
Added checkbox to remove duplicate rows from table.
Note that tables in existing projects are not automatically updated to the new table format which supports these features, and tables must be readded to a composition for the new settings to appear.
The map composer (used to prepare printable map compositions) has received a number of improvements in QGIS 2.6.
You can now change the secondary fill color for scalebars
Holding shift while drawing line/arrow items constrains drawing to horizontal, vertical or 45 degree angles
Holding shift while drawing other new items constrains them to squares, holding alt causes item to be drawn from the center
Right click no longer locks/unlocks items, this is now handled by the new items panel. Locked items can no longer be selected from the composer canvas, allowing for interaction with items below them.
Holding alt while pressing cursor keys results in a 1px movement for items
Removed the destructive „Load from template“ menu item, replace with a new non-destructive „Add items from template“ action
Snapping thresholds are now set in pixels, allowing for finer movement and resizing of items when zoomed in to a composition. Items within a group are no longer used for auto snap lines.
Sometimes it is useful to be able to show more than one overview frame for a map frame. For example if you want to show where your map is in local, regional and global context, using multiple overview maps can help you to achieve this. As of QGIS 2.6 you can now achieve this by assigning as many maps as you like to the „overview“ role in your composition.
There are a number of useful new options for the HTML composer item:
Option for manual entry of HTML source
QGIS expressions within HTML source can be evaluated prior to rendering HTML content
Data defined URL for HTML source
Allow for creating a user stylesheet to override HTML styles
You can now have multiple grids with different properties.
You can mix reprojected grids and Lat/Long grids.
You can use standard QGIS symbology grid lines etc.
There is a new frame/annotations only grid style. Selecting this style causes only the frame and annotations to be drawn, with no grid lines or other markings over the map.
There are now options for controlling which side of a map item the frame is drawn on.
There are new tick styles for frames, with inner ticks, outer ticks and both inner and outer tick options.
We have made improvements to grid annotations, including many new formats for annotations.
Grid annotations now use the typographically correct prime and double prime symbols for grid annotations.
Models and scripts can be downloaded from the online collection and installed directly from the Processing interface. The collection will be expanded with new scripts and models provided by Processing users.
The modeler has been rewritten, and now provides extra functionality such as allowing nested models with no depth limit. Models are now stored as JSON files. Backwards compatibility is kept, so all models can still be used. You can also now drag and drop items from the inputs and algorithms onto the modeler graph.
In order to normalise the naming of QGIS widgets, some minor API changes have been made. Almost all edit widgets were renamed by adding «Wrapper» at the end of their names. In particular this concerns:
QgsCheckboxWidget -> QgsCheckboxWidgetWrapper
QgsClassificationWidget -> QgsClassificationWidgetWrapper
QgsColorWidget -> QgsColorWidgetWrapper
QgsEnumerationWidget -> QgsEnumerationWidgetWrapper
QgsFilenameWidget -> QgsFilenameWidgetWrapper
QgsHiddenWidget -> QgsHiddenWidgetWrapper
QgsPhotoWidget -> QgsPhotoWidgetWrapper
QgsRangeWidget -> QgsRangeWidgetWrapper
QgsTexteditWidget -> QgsTexteditWrapper
QgsUniquevalueWidget -> QgsUniquevalueWidgetWrapper
QgsUuidWidget -> QgsUuidWidgetWrapper
QgsValuemapWidget -> QgsValuemapWidgetWrapper
QgsValuerelationWidget -> QgsValuerelationWidgetWrapper
QgsWebviewWidget -> QgsWebviewWidgetWrapper
We have improved the random colour algorithm for classified renderer so that the colours generated are more visually distinct from each other.
Where possible, properties of symbol layer are maintained when changing symbol layer type.
Added an edit button for shapeburst and gradient color ramps.
Automatic update of label and neighboring ranges boundaries.
Classes are automatically converted from categorised and graduated classes when switching to rule based renderer.
Added units and number of decimal places to graduated renderer labels.
Improved responsiveness to changes in color ramp, inverted colour ramp, and other options in GUI.
Retain symbol when switching between simple, graduated, categorized, and other renderers.
Improved labelling of StdDev calculation mode.
For python script editors, expression builder, filter window, composer HTML and CSS editors
You can now define your own custom color palettes for use in QGIS.
Custom user global color palette (in options dialog).
Per project color palette (in project properties dialog).
Colors are shown in color button menus and new color picker dialog.
You can import/export colors to a GPL palette file.
Sliders for hue, saturation, value, red, green, blue color components.
Option to copy/paste html color codes (in a variety of formats).
Before/after color preview, with alpha preview.
Interactive 2D color ramp widget.
Hue wheel/triangle widget.
Editable color palettes, including the ability to create new palettes and import/export colors to a GPL palette file.
Live color sampler with option to sample over a set radius (OS support dependant).
Supports interaction with other apps via drag and drop of colors (OS support dependant).
Option to disable the dialog and use the native picker dialog instead.
We have merged the single selection tool into the rectangle tool. If you want to select a single feature, simply enable the rectangle tool and then single click (rather than dragging a rectangle) a feature.
In many of QGIS“ dialogs that generate a new layer, the „Add layer to map canvas“ checkbox is now checked by default so that the new layer automatically gets added to the map.
For those using QGIS on touch devices (or if you just like big, chunky icons), you can now set the icons up to 64 x 64 pixels in size.
