History

#1 Updated by Giovanni Manghi about 11 years ago

  • Priority changed from Normal to Severe/Regression

#2 Updated by Andreas Neumann about 11 years ago

Steps to reproduce:

  • Empty project
  • load shapefile
  • start digitizing --> snapping is active even if it is not turned on in the snap settings dialog

#3 Updated by Andreas Neumann about 11 years ago

Things are even worse:

once I start changing snapping settings - I cannot digitise anymore - I always get the error message:

Could not snap segment - did you set the snap tolerance in Settings > Project Settings > General?

So - there seems to be something quite messed up with snapping currently.

#5 Updated by vinayan Parameswaran about 11 years ago

here is one thing that i noted in commit:5feebe1
  • snapping is on even though the settings->snapping option is not checked for the layer when qgis starts up.
  • if you just click the apply without changing anything snapping is really disabled.
  • From then on, everything works as normal

#6 Updated by Andreas Neumann almost 11 years ago

yes - I can confirm that. Once the "Apply" button is pressed the snapping is turned off correctly. However, initially it is activated, even when it is displayed as turned off in the snap settings panel.

Looks like that's intentional - it follows the defaults in options / digitizing.

#9 Updated by Andreas Neumann almost 11 years ago

hm - but there is no way to disable snapping by default.

In "Options" one can only set the default snap mode, the snapping tolerance and search radius. No way to turn it on/off globally.

Also - if it were turned on by default - the snap option dialogue needs to indicate that by having the checkbox turned on - but it is turned off. So it seems the checkboxes are out of sync with the setting.

I do not think the current behaviour is satisfying.

Hi Jürgen,

Thank you for working on this problem.

I can see the Default Snap Mode "Off" option now - this is good.

However, if this option is on (e.g. vertex), and a user adds a new layer, the snapping is on (correct) but shown as "off" in the snapping options dialogue (incorrect). So this part of the bug is not yet fixed. The disconnectedness of the Snapping options dialogue. This dialogue should always reflect the current state - but it doesn't. Do you understand my problem?

I re-opened the bug therefore again. Or should I open a new bug?

Andreas
