I have a layer in my system that displays nautical sectorlights. If sectorlights are close together the symbology overlaps, wрich I don't want.
I would like to see the star at all times, but see the dotted lines, colors and arc-indicator when the layer is active and I hold my mouse on the star.
Are mouseover actions possible in QGIS? Can a mouseover action be invoked as a parameter in an Expression Builder?
if( [mouseover]=true, 1, 0)
At the moment I am using a layer without geometry as a reference layer. I keep the attribute table open while working and if i check the box on "sectorlichten-uitgebreid" the symbology will show on screen. I had hoped to evolve to a mouse-over action, my thoughts: There is mouse-over functionality being used on maptips and, in a way, the snapping-function is doing what I am looking for: when you come within a set px of a point, a purple box (symbology) will appear, indicating you are snapping to a geometry. I had hoped this signal was available to invoke functionality in the expression-builder.
is_selectedfunction would make a crude workaround.
