This adds a new gui widget QgsFieldValuesLineEdit which includes
an autocompleter populated with current field values.
The autocompleter is nicely updated in the background so that
the gui remains nice and responsive, even if there's millions
of records in the associated table.
It's now used as a search widget for text fields, so can be seen
in the browser window if you set the filter to a text field, or
if you launch the form based select/filter by selecting a layer
and pressing F3.
This is replaced with a QVariantMap. It was never really more than this in the
past and with the switch to QgsConfigurationProperties, there is really no
longer any reason to assume that this will change.
This commit implements the improvements described at:
https://lists.osgeo.org/pipermail/qgis-developer/2016-September/044393.html
The QgsRasterMinMaxWidget now offers a seetting to specify that the statistics
should be computed each time the canvas extent changes.
Other changes:
- the content of the QgsRasterMinMaxWidget is now persistant.
- there is no longer any Load button. The global Apply / OK button of the raster
properties dialog has this effect.
- the default "limits" for single band raster is now MinMax and not CumulativeCut
- the default "limits" can be configured for single band, multi band single byte and
multi band multi byte
- "Strech using current extent" honours the "limits" instead of forcing min/max.
above a layout.
Supports setting another widget as a anchor point for the widget, eg
the floating widget could be set so that it's always placed to the
top-right of the anchor widget.
Adds new classes:
- QgsTask. An interface for long-running background tasks
- QgsTaskManager. Handles groups of tasks - also available as a global
instance for tracking application wide tasks
- QgsTaskManagerWidget. A list view for showing active tasks and their
progress, and for cancelling them
A new dock widget has been added with a task manager widget showing
global tasks
- create a dedicated set of buttons for addition of tags and smartgroups
to make those actions more visible as well as getting rid of th need to
select a tag/smartgroup to create those (turns out to be quite confusing
for newcomers)
- move UI elements around, regroup {add,remove,edit} symbol buttons to
harmonize with other parts of QGIS; the elements' placement feels much
more natural now
These may represent additional layers such as layers which
are not included in the map layer registry, or paths to
layers which have not yet been loaded into QGIS.
Within the attribute table, there is a new button to trigger actions
which are not based on individual features but instead on the whole layer.
Normally they will perform actions based on all features or the selection.
In addition to this, a lot of cleanup has been done.
- A new favorite grouping system was added, which the symbols list
widget defaults to
- The selected tag / smartgroup in the symbols list widget now
persists when switching layers (and across sessions)
- The symbols list widget will update the tag / smartgroup combo
box when users add / rename / remove categories
- Users can now directly tag, as well as add to favorites, symbols
while saving those to the style database
- To streamline style management, groups have been removed and
fully replaced by tags
- Tags have been integrated into the import/export user interface
fixes#14703
Include C++ and Python tests
Travis won: ported all test cases to Python
and disabled C++ companion test (still useful locally and
for debugging)
For the curious: QTemporaryFile is not working as expected
Moved to Qt5 new style signals
Disabled C++ test and connected cancel to progress
Make string comparison on SSL errors more robust
Warnings are shown, but features can be committed. Fields which
fail an unenforced constraint are now shaded in yellow to differentiate
from the red failure for enforced constraints.
