Step to reproduce:
1. click editing toggle

Shouldn't "Node Tool" at least "obbey" project snapping configuration?

Is this still valid in the current version, i.e. QGIS 3.4?

#3 Updated by sand thorn almost 2 years ago

Version: 3.4.1
Platform: Windows 10 x64

The symtoms still there. Node tool still sees everything when cursor is near-by the shape in hidden layers

#4 Updated by Bernhard Ströbl almost 2 years ago

Hmm, I cannot reproduce this here (QGIS 3.4.1 on Ubuntu). Could you make a film that shows the error?

#5 Updated by sand thorn almost 2 years ago

When node-tool enabled, when cursor moves near lines of other hidden layers, it shows that shape.

weird, I don't even get the features of another layer highlighted if the layer is visible (and not editable), tested 3.4.1 on Ubuntu and master on Win7 (64 bit)
@Giovanni: the snap settings do not matter either

I can only consciously produce this behavior if I activate the options "Enable snapping by default" and "Enable snapping on invisible featrures ..." under "Settings -> Options -> Digitizing" (tested on Win 7, 3.4.1 and master).

That's weird. Even when those two settings are off both--"the red magnet" and snapping on invisible..., I still am seeing hidden layers! when using node tools.
I can even edit nodes in invisible layers that enable editing.

Another weird thing is that I can snap the node of invisible layers with the shown layers but not vice versa. In other words, while moving current layer's node around, I don't see invisible layer anymore.

With "Add Polygon" tool, I see no invisible layers, even when those two settings are on and with "Snap All Layers".

#11 Updated by sand thorn almost 2 years ago

Still to be reproduced in 3.4.2

Version: 3.4.2
Arch: x86_64
Platform: Windows 10 64-bit

It seems that
1. "Vortex Tool (Current Layer)" behaves like "Vortex Tool (All Layers)"
When cross hair is near a shape in invisible layer, you will see that shape "pop-up" to scene and you can edit invisible layer if it is in editable mode.
2. Configuration / Digitizing / Snapping / Snap invisible shapes seems not working.
