Hi, Yes, I was meaning "check if there is an unfinished drawing".
I made some trials and tried to remember all the tools I have been using for digitizing. Digitizing may be fun sometimes but I have been doing it quite a lot and I hate doing it in an ineffective way. Here comes my conclusions from power digitizers point of view. Digitizing is fast and fun when user does not need to move one's eyes away from the region of interest. After panning or zooming the user should have the cursor pretty close to the next vertex to be inserted and sight focused around there. For that panning by Click and drag is good. Even better if can be done with one hand like in OpenLayers, Leaflet and Potlatch, which is the OpenStreetMap online editor. However, OpenJUMP with Shift-Alt shortcut is equally good for panning if operator is using a normal mouse and keyboard and keeps mouse in the right hand. Operator can also simply zoom in/out because one finger is already on the Alt key. For my mind the second best way to pan during drawing is to use the "Center to click" tool from the context menu attached to some EZ Button. For one hand operation this tool should be the upmost item in the right click menu and absolutely not in the submenu where it is too hard to hit. Most part of the speed and fun is lost if operator must change tools while drawing large features. For selecting the new tool user must move eyes away from the map and it breaks the concentration. Therefore after re-thinking I do not care anymore about changing automatically back to drawing mode after first pan. It is an unpleasant way to digitize any way and it is indeed more logical for a new user it tool stays active until another tool is selected. This is also how it is implemented in QGis. By the way, also the keyboard shortcuts in QGis are implemented so that the selected tool stays active until another one is selected with another shortcut or from toolbar. Logical but a bit ineffective. For new users it may be more important to be able to guess how tools should be used without reading manuals. Uwe may know best how the beginners feel. Click and drag works very well in our Super zoom tool but I do not know if it could be used during drawing. -Jukka- edgar Soldin wrote: > you mean, check if there is an unfinished drawing? that'd be possible. but i > am still not convinced that switching back after panning once is a good idea. > the behaviour is intransparent to an unsuspecting user, as the tool > deactivates itself although explicitly activated. > this might be a good advanced option, but no idea for a default behaviour. > > are there any takers? i for myself am not convinced it is worth the effort. > if not, up into the feature request tracker with it. > > ..ede > > > On 15.04.2013 12:48, Rahkonen Jukka wrote: > > Check if there is at least one vertex inserted into the new feature.
