Hi,
The plugin seem to not works with QGIS 3.8.
The text area display :

ERROR: Layer selected is not vector

When pushing the WKT-button 2 problems occur.
Problem 1: everything is a multipolygon, even single polygons
Problem 2: although not visible in the windows, when copying the data, the attribute table data is included in the copy. This can become a problem when you paste it in an other application.

Mac OS 10.14.6
QGIS 3.10
GetWKT 1.3

This error came up when trying to install your plugin.

Couldn't load plugin 'QGIS3-getWKT' due to an error when calling its classFactory() method 

TypeError: 'QVariant' object is not subscriptable 
Traceback (most recent call last):
  File "/Applications/QGIS.app/Contents/MacOS/../Resources/python/qgis/utils.py", line 423, in _startPlugin

This plugin is really good but it occupies too much space for small functionality that is not used often. I would suggest reducing the space buttons occupy by having a setup like what QGIS has for Deselect Features. See Picture.

It is important to me because I have many plugins installed. Thanks

Simply copying a feature copies also its WKT representation.
What does the plugin add to it?
Thanks.

Getting the following Python Error when I run the plugin to get a polygon's WKT. Running QGIS 3.16.2 and Python 3.7

Great plugin, just what I was looking for 😄

Would be great if the WKT text area would resize with the dialog to be able to get a better overview of the data:

When getting the WKT for polgyon with z values, the format does not following the standard (see section 7.2.3): there should be a space between "polygon" and "z".

E.g. when getting the WKT for the following GML layer:

<ogr:FeatureCollection
     gml:id="aFeatureCollection"
     xmlns:ogr="http://ogr.maptools.org/"
     xmlns:gml="http://www.opengis.net/gml/3.2">
	<ogr:featureMember>
		<ogr:export gml:id="id.1.geom">
			<gml:boundedBy>
				<gml:Envelope srsDimension="3" srsName="http://www.opengis.net/def/crs/EPSG/0/7416">
					<gml:lowerCorner>722120.48 6178866.39 24.28</gml:lowerCorner>
					<gml:upperCorner>722184.83 6178905.66 25.01</gml:upperCorner>
				</gml:Envelope>
			</gml:boundedBy>
			<ogr:geometryProperty>
				<gml:Polygon srsName="http://www.opengis.net/def/crs/EPSG/0/7416" gml:id="id.1.geom">
					<gml:exterior>
						<gml:LinearRing>
							<gml:posList srsDimension="3">722178.52 6178866.39 24.61 722184.83 6178880.97 24.61 722137.52 6178901.05 24.7 722135.5 6178901.91 25.01 722126.66 6178905.66 24.61 722120.48 6178891.19 24.61 722126.3 6178888.7 24.28 722178.52 6178866.39 24.61</gml:posList>
						</gml:LinearRing>
					</gml:exterior>
				</gml:Polygon>
			</ogr:geometryProperty>
		</ogr:export>
	</ogr:featureMember>
</ogr:FeatureCollection>

The WKT retrieved with the plugin is
PolygonZ ((722178.52000000001862645 6178866.38999999966472387 24.60999999999999943, 722184.82999999995809048 6178880.96999999973922968 24.60999999999999943, 722137.52000000001862645 6178901.04999999981373549 24.69999999999999929, 722135.5 6178901.91000000014901161 25.01000000000000156, 722126.66000000003259629 6178905.66000000014901161 24.60999999999999943, 722120.47999999998137355 6178891.19000000040978193 24.60999999999999943, 722126.30000000004656613 6178888.70000000018626451 24.28000000000000114, 722178.52000000001862645 6178866.38999999966472387 24.60999999999999943))

It should start with Polygon Z, not PolygonZ.

There is an additional issue: the plugin also returns too many decimals, these are not specified in the GML. But that may be a QGIS issue?

When using ogrinfo:

ogrinfo export.gml -wkt_format WKT2 -al -q

the result is

Layer name: export
OGRFeature(export):0
  POLYGON Z ((722178.52 6178866.39 24.61,722184.83 6178880.97 24.61,722137.52 6178901.05 24.7,722135.5 6178901.91 25.01,722126.66 6178905.66 24.61,722120.48 6178891.19 24.61,722126.3 6178888.7 24.28,722178.52 6178866.39 24.61))

And when using ogr2ogr:

ogr2ogr -f CSV export.csv export.gml -lco GEOMETRY=AS_WKT

the result in the CSV file is also

POLYGON Z ((722178.52 6178866.39 24.61,722184.83 6178880.97 24.61,722137.52 6178901.05 24.7,722135.5 6178901.91 25.01,722126.66 6178905.66 24.61,722120.48 6178891.19 24.61,722126.3 6178888.7 24.28,722178.52 6178866.39 24.61))

So ogr writes the WKT according to the standard, including a space between polygon and z.

IBM does it according to the standard too, see https://www.ibm.com/support/knowledgecenter/SSHRBY/com.ibm.swg.im.dashdb.spatial.doc/doc/rsbp4120.html?view=embed

Thanks for writing this excellent plugin. It is useful for me because I have the default WKT copy option turned off. I can use this plugin without having to turn it on.

The issue that I am having is that once I have a WKT window open and then click a different feature and then click the plugin buttons the pop-up window will be buried under other windows and will not pop up to the front.
