Fixes an unreported bug where it was possible to select a layer tree group
and remove even when it contained required layers.
When removing layers/groups, the following checks will now also recursively
test layers and not just directly selected layers:
- test for layers with unsaved changes
- test for layers with active tasks running in background
data defined buttons for model child algorithms
The context was not previously exposed, so users would not have
been aware that they can utilise all the variables and functions
available to parameters within child algorithms.
for pre-calculated expressions
Correctly exposes ALL the variables and functions available for use
in pre-calculated expressions so that users actually know they can
use these in their models!
The context contains settings which reflect the context ini
which a Processing parameter widget is shown, e.g., the
parent model algorithm, a linked map canvas, and other relevant
information which allows the widget to fine-tune its behavior.
Until now the identification from 3D map view used tolerance based
on the current view of the main 2D map canvas - that was giving often
unexpected results if the 2D map canvas had significantly different
zoom level from the 3D map view.
With implementation in app. This allows GUI library classes to
re-use standard dialogs which are created in app. The initial
use-case is to allow the GUI library symbol list widget to
focus/open an existing Style Manager dialog (created in app),
instead of opening a new modal style manager dialog.
Side benefit - moves some code out of the monolithic qgisapp.cpp
file.
removed the .sip
corrected (f)
removed direct comparison of doubles to try to pass the tests
one step back to know if it cause the check failure
the step forward, improved, should pass the test
comments of m-kuhn taken into account
The last 7 commits to rebase easily on master
Until now the tool only considered terrain. This commit adds support
for 3D renderers created from vector layers, so it is possible to
correctly identify polygons and linestrings in 3D.
