Using this renderer no symbol will be drawn for features, but labeling,
diagrams and other non-symbol parts will still be shown.
Selections can still be made on the layer in the canvas and selected
features will be rendered with a default symbol. Features being edited
will also be shown.
This is intended as a handy shortcut for layers which you only want
to show labels or diagrams for, and avoids the need to render
symbols with totally transparent fill/border to achieve this.
(fix#12131)
First part of https://github.com/qgis/QGIS-Enhancement-Proposals/issues/53
(QEP 35: WFS provider enhancements)
Improvements:
- Version autodetection
- On-disk caching of downloaded features
- Background download and progressive rendering
- WFS 1.1 and 2.0 support
- WFS 2.0 GetFeature paging
- Add provider tests
Fixes:
- #10106: Panning a non-cached WFS layer causes selection to change
- #9444: WFS client not requesting new features when not-cached
#14156: WFS non cached: infinite flashing
- #9450 : New WFS connection option - Max number of features returned
- #14122: Implement WFS 2.0 client provider (partial. no joins or stored queries)
Not in scope: WFS-T 1.1 and 2.0. But WFS-T 1.0 kept (and tested)
label font and margins when rendering as HTML.
This allows interactive choice of font, margins and colors and
avoids the need to manually set these with CSS within the
label HTML code.
