implements Processing providers
Plugins which implement providers should include the
hasProcessingProvider=yes
line within their metadata.txt file. This allows for rapid
identification of all plugins which implement Processing
functionality.
This command adds a plugin to active plugins and calls initProcessing(),
initializing only Processing related components of that plugin.
The new initProcessing() hook should be implemented by plugins
which provide Processing providers or algorithm, and should only
implement code which is required to load the provider and algorithms.
Strictly no GUI related code should be used here, that MUST
be moved out of initializers and deferred to the plugin's
initGui implementation.
For non-point geometry subclasses (points are always valid!) we
now cache the results of a geometry validity check. Subsequent
checks utilise the cached result wherever possible.
Because QgsGeometry/QgsFeature objects are implicitly shared, this
means that we avoid a *lot* of duplicate validity checks as
features and geometries are thrown around during processing model
execution.
The new behavior is to store a value in user's QSettings
(that overrides the global settings) only if the the value
has changed from the default reported by QgsSettings.
If a value was changed and it is changed back to the default
the override must be removed from the user settings.
The rationale is that global settings should be the ultimate
source of default values, unless the user override the
default with a different value.
Fixes#21049
For the c++ api dox this expands to "\c nullptr" (the
\c directive indicates a code literal value), and for sipify/Python
it expands to ``None`` (`` is sphinx annotation for literal values)
Makes for nicer dox for both c++ and Python!
* [QgsQuick] - extended externalResource widget
Added removeFile function and modified fileName function - former has been missing and photoPanel is using it. The latter needed modification due to a new option to choose image from a gallery.
Added externalResource handler for externalResource widget which enables following features:
* option to choose an image from a gallery - selected image is copied to projects folder, if it doesnt exists there. Added "ic_gallery" icon.
* ability to remove value for externalResource field. Optionally removes referenced image as well ("Ok" option in dialog)
* ability to interact with image preview onClick - the main idea is to have ability to enlarge preview image. Currently its possible only in edit state of the form since the whole field is disabled otherwise.
Fixed resizing of icon/previewImage and component itself as well.
* [QgsQuick] - extended externalResource widget
Commit contains following fixes/changes/additions after review:
* Added QgsQuickUtils::getRelativePath which replaced QgsQuickUtils::getFileName + related changes in photoPanel
* Added test for new QgsQuickUtils functionality
* fixed weird or redundant size definitions in externalResource widget
* Some changes in docs.
* [QgsQuick] Changed "default" case result for QgsQuickUtils::getRelativePath
* [QgsQuick] Fixed test after changed functionality in QgsQuickUtils
This adds a second variant for the existing "attribute" function.
The current function requires both a target feature and attribute
name to be specified, while the NEW variant just uses the current
feature.
E.g.
NEW:
attribute( 'name' ) -> returns the value stored in 'name' attribute
for the current feature
EXISTING:
attribute( @atlas_feature, 'name' ) -> returns value stored in 'name'
attribute for the current atlas feature
It's just a faster shorthand version!
* fixes#20516 : Allow Constraint widget in attribute type form to be empty so expression could be removed
per widget modification
* correct tests
* Add the clear button on field expression widget when widget is allowed to be empty
* Change API since version to 3.6
