This is supported by the toolbox now, so relax the requirement
that all models have a compulsory group name. If no group is set,
the model is shown directly under the Models node in the toolbox.
Also switch a warning from message box to message bar
Because there's some deep underlying issue which causes the dock
layouts to get corrupted in certain circumstances, avoid the
issue entirely by moving construction of the docks out of
the .ui file and instead do it all manually via Python code.
Fixes#16428, #19068
This is used in the algorithm's tooltip in the toolbox, and is intended
for single sentence description of the algorithm, e.g.
"Converts 2D features to 3D by sampling a DEM raster."
Convert grass algorithms to use short description for the
descriptive parts of their names, to cleanup the toolbox
and make it more uniform.
This is a subclass of QgsProcessingParameterNumber, but specifically
for numeric parameters which represent distances. It is linked
to a parent parameter, from which the distance unit will
be determined, and is shown using a dedicated distance widget
within the processing parameters panel. This widget shows
the distance unit.
This avoids the confusion when running algorithms which
use distances where the unit depends on a layer or CRS parameter -
e.g. the distance parameter in the buffer algorithm gives
the distance in layer units... so now we can show those units
directly within the dialog. Hopefully this leads to less
user confusion and accidental "1000 degree buffers"!
Additionally - if the unit is in degrees, a small warning
icon is shown next to the parameter. The tooltip for this
icon advises users to reproject data into a suitable
projected local coordinate system.
Initially implemented for the native buffer and single
sided buffer algorithm only - but more will be added.
Fixes#16290
ModelerParametersDialog and ParametersPanel have to keep list of
wrappers only. widget and label( if needed) are created through
WidgetWrapper.createLabel()
