Makes sure that any two vertices of the vector layer are at least at distance given by the threshold value.
The algorithm moves nearby vertices to one location and adds vertices to segments that are passing around other
vertices within the threshold. It does not remove any vertices. Also, it does not modify geometries unless
needed (it does not snap coordinates to a grid).
This algorithm comes handy when doing vector overlay operations such as intersection, union or difference
to prevent possible topological errors caused by numerical errors if coordinates are very close to each other.
After running the algorithm some previously valid geometries may become invalid and therefore it may be useful
to run Fix geometries algorithm afterwards.
This block was swallowing all exceptions within the voronoi method.
Removing the block causes exceptions throw in the method to propagate up
the stack and eventually become visible in log files.
* [metasearch] Use QgsFilterLineEdit for keyword search box
* [metasearch] Remove version number from dialog title
This is no longer required now that the plugin is bundled with
QGIS - the version number now follows QGIS version numbering
* Capitalization, ellipsis
* [metasearch] Use a question messagebox
Adds GIS File link type to known link types, and for records with
a FILE:GEO link enables a new "Add GIS File" action. Clicking this
adds the linked GIS file to the current project.
Also exposes this capability to modeler - so that model algorithms
can use data defined parameters within their child algorithms.
TODO:
- tests
- setting the associated vector layer
A new widget which handles parameter values for child algorithms
within a model. Instead of the previous approach of requiring
individual widget wrappers to handle creation of a suitable
model widget, we do all this automatically for them.
This widget uses a stacked widget with a toolbutton to select
the parameter's source, instead of the previous combo box approach
(which didn't scale well for large models). I.e. users select
first whether the value is taken from a static value, a
model input, or an output from a different child algorithm. The
widget then changes appearance and behavior based on this
choice.
Additionally, a new option is present for all parameters
of using a "precalculated expression". This expression is
evaluated once before the child algorithm is executed
and used during the execution of that algorithm.
- Add abstract base class for Processing widget wrappers to c++
- Add wrapper factory interface to c++
- Make QgsProcessingGuiRegistry also register widget wrapper
factories, and be responsible for creation of new c++
processing widget wrapper instances
- Start on private c++ implementation of boolean widget wrapper,
including unit tests
