Re: [Qgis-developer] Identified features vs. Selected features : could we merge those ?
Hi, I am skeptical - mainly for the reasons you list in your rationale against it. Selection and identification are really two different tasks. You do not want to loose your selection just because you want to query the attributes of the feature. Identification works with all layers, while selection should only work on the selected layer to get predictable results. Users should be making selections intentionally rather than by accident because the selection works on all layers and they are not aware of what they are doing. The identify tool has been improved several times - we added the top-down-stop-at-first mode (which most of my users like) and then later on the new layer choice mode with an interactive choice in a drop-down menu. So we have 4 modes now, with the two described above as the more powerful ones. I still think there is a use-case for all of the four modes, but maybe the most recent addition (the layer choice mode) should be the default. Selection is essential in GIS - useful for exporting features, run analysis only on selected features, field calculator updates, plugins, processing, etc. The identify mode should not change the selection. The selection tool was improved over time as well, with shortcuts, free form selection, circular mode, etc., etc. I am open to improving the identification tool (e.g. by opening the form in the mode where one can toggle between table and form easily instead of just the form) - but please let's keep the selection and identification tools separated.

In short, the idea would be to have both identified features and selected features be exactly the same thing. The only difference between the select tool and the identify tool would then be that the identify tool opens a form window (either the single feature form or the attribute table in form mode). The identify tool could then also work in single,rectangle,polygon etc modes. Rationale FOR: 1. There is already a feature overlap When identifying one feature only, the identify tool can open the form (provided open feature form if a single feature is identified is checked). But when identifying several features, the way to go is a selection, which dynamically refreshes the attribute table, and where the features can be edited in the form mode. This is also a problem in the scenario of issue #9907 : to open the form of overlapping features, you have to use a selection, if you don't want to spend too many clicks expanding the identify window tree, finding the right feature, and clicking on it's open feature form button. This also has the annoying consequence of being unpredicable : the effect of the tool will sometimes be opening the form (when one feature gets identified), and sometimes to open that identifying results window (when several features got identified). *2. The attribute table in form mode is actually great* The identify results window is not very practical: the folded tree requires expanding, it does not provide a good overview of what is selected, does not take editing widgets into account etc. Meanwhile, the form view is great (both the single feature form and the multiple features form in the attribute table). It's clear, neat, even allows to choose which field to use to list the selection, etc... It's sad that it's a bit hidden in the UI, I find it one of the best additions to the UI that has been made lately. *3. Both functions are very similar in how they work and look* Both require you to click on a feature, and have a visual feedback consisting of highlighting the feature. It's very confusing for beginners as it's uncommon for softwares to implement two different types of selections. *4. Having the attribute table in form mode for editing is promising for the future* Because we could implement edition on several feature at once (currently, one needs a plugin to set an attribute on different features at once, and those plugin do not yet take the field widgets into account). Rationale AGAINST (and of course counterarguments) : *1. Identification is not the same than selection* Users sometimes want to work on a selection, while still being able to identify features. To allow this usage, either we could offer workaround features by implementing store/restore selections and/or have selections in the undo stack (grouped), or we could make an exception for the identify single feature, which would not set the selection, but only open the feature form

Re: [Qgis-developer] Identified features vs. Selected features : could we merge those ?
+1 with Andreas for the same reasons . Another one is that we should really now take care of not changing ergonomy of main tools on each version...because many users took time to learn a professionnal tool, and have difficulties with self learning. IMHO, strong ergonomy changes should be grouped and tested alltogether in depth. I start to have users not liking a lot that tools change so often their behaviour (not me) , like digitizing end click.. Please I agree identify window needs some improvements, but I think this is a mandatory feature . Some tweaks I had in mind (tickets existing for a while): - ability to change the options (first layer, current layer...) and open feature form accessible from identify window - abitlity to have fields in table order, or alphabetic order - semi-transparency (adjustable) - tooltips on fields that show fields comments and field true name if alias is set.

Re: [Qgis-developer] Identified features vs. Selected features : could we merge those ?
Hi ! Thanks for your reactions ! Below is an updated suggestion, which tries to keep the spirit of separated identified features and selected features concepts, while still providing some usage improvements. One thing I'm not at ease with is the point about not changing the ergonomics. I mean, if we find out a better/more simple way to do something, we have to do it. The fact that users are used to an old unpractical way is no good reason for not doing it. Because if it was, we'd be stuck in improving QGIS. It's a matter of minutes to get used to this type of changes, and if a user really doesn't accept change at all, he's still free to stick to his current version. I find it better to think of new users when thinking about the UI, because it helps going for the most simple and logical implementations. Plus, I guess in the case of QGIS, it's more of a challenge to attract new users than to keep the old ones. That doesn't justify change for the sake change, but we are talking about improvements (even if small), not just changes. *Identify features window* *Régis:* *I agree identify window needs some improvements, but I think this is a mandatory feature* Can you develop on this ? The only feature I see is that it displays those derived information (currently areaperimeter) which can't be found easily otherwise. But: - Is it the best way to show them ? When having show form if only one feature is identified, you can't show them on one feature anymore. - It's still several (hard) clicks to display that information. - Wouldn't map tooltips be better ? Maybe we could have those info display by default as tootips on vector layers ? - What if I'm interested in other derived information (centroid...) or if I want to customize those (number formatting...) ? The other features (discriminating one layer from multiple identify results) is done much better by that select layer mode. In case of overlapping features (in a same layer), we could have the same dropdown menu (or submenu, in case we have overlapping features in the same layer + overlapping layers) to choose which feature you want to identify. Exactly the same implementation would be perfect for the action tool. This would actually be enough to replace the identify results window. The real time visual feedback on what's going to be identified is great, and a contextual (sub-)menu is much more friendly than a tree. Having each time only one feature identified, it would always open the feature's form, and never open the identify results window. I'd be very happy with that !! *Identify multiple features* I still find the idea of being able to open the attribute table in form mode for several features great. Maybe for this, we could have subtools (under the identify tool) called Identify by selection, Identify by rectangle selection, Identify by polygon selection, ... which would work as said, i.e. exactly like the selection tool except that they open the attribute table in form mode. This would make it clear that it's actually going to define a selection, and make the attribute table in form mode much more accessible. So we get the best of the two worlds : ability to identify a feature even if there's currently a selection, and also being able to take advantage of the great current implementation of the attribute form mode and the flexibility of the selection tools. I believe this will be awesome at the point we implement modifying attributes of several features at once. *Alvaro:* *To avoid repainting the full content of the map when the selection changes (it can very heavy for big contents), I find it interesting to modify how the highlight of the elements is done by painting similar to how it does the identification tool (it uses QgsHighlight class).

[Qgis-developer] Dropping vertices at intersections
Hi All, I've looked at the topology plugin, but can't find what I need to do. I've been exporting the data into Genamap and doing this with scripts, but it would be nice to do it in QGIS. Anyone know of a plugin? Quite often now we've been asked to deliver products whereby there are vertices placed onto graphic elements where they cross over, or end on, each other (in different layers (Shape files)). eg: A road line stops at the edge of a cropfield polygon, so drop a vertice at that place, on the cropfield boundary. Likewise if a road runs through a field, but the data capture scale requires the field not to be split into two polygons, drop the vertice at the points where the road crosses over the field boundary. Ideally this could be implemented by: * Check boxes to select all the layers you want to process (mixture between multiple polygon and line layers) * selecting the snapping distance (for lines that end close enough to other boundaries or lines). * Having a separate checkbox for Crossover and for Line ends * Perhaps even an option to log (create a pointfile) when lines end within 'X' of any boundary or line (where X is a secondary snap distance) * perhaps have an option to log (point file) where lines run parallel to others, within the snap distance set (maybe with even a tertiary snap distance) Instead of looping through multiple snap distances, one could implement a checkbox to either drop the vertice, or to just mark the position where the vertice should have been dropped - this would be easier for the developer, but require the user to run the procedure multiple times, in order to see where close enough stuff lies.

Re: [Qgis-developer] Georeferencer: not rotating if using Linear transformation
Hi Paolo, Linear transformation creates only a world file and doesn't transform the raster if the user manual can be trusted. What you described sounds like a Helmert transformation which uses coordinate offset, rotation and scale as parameters. -Lauri On Thu, Apr 3, 2014 at 2:50 PM, Paolo Cavallini cavall...@faunalia.itwrote: Hi all.

[Qgis-developer] How to create a Textual Note auto filled with fields ?
Hello All, ( Sorry for my english, but I try to explain my need as better as I know ). I need to create textual notes on many polygons, with QGis, and I would like to automate more than possible the process. For the moment, I created an Action, defined as following: Note_ACTION echo [%'\n\nPolygon (mq) :\n' ||'Area: ' || toint( round ( $area)) || '\n' || 'Perimeter: ' || toint( round ($perimeter)) %] In this way, clicking on each polygon I have the text I need. :) But, for the moment, it is necessary to copy the text and paste it inside the Textual Note. It could be possible to... create the action in a way that creates directly the Textual Note with the text inside ? Could somebody give me suggestions about this ? Thank you in advance Roberto ___ Qgis-developer mailing list Qgis-developer@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-developer

Re: [Qgis-developer] Identified features vs. Selected features : could we merge those ?
Hi Oliver, I agree with Regis we can't be making this kind of changes very often based on this many users took time to learn a professionnal tool, and have difficulties with self learning, this is specially true when you look at tutorials online which haven't been updated for 2.0 or 2.2 and can make the life of novice users hell. I think improvements are always welcome, but maybe big changes like this should be worked and maybe even create a pull request for it but not merge it until a 3.0 release maybe? Just a thought On the identify vrs Selected, I think most or all current used GIS software have this functionality, right now I think a lot of users from certain vendor are looking for QGIS to switch and the first thing you do when you get a new software is to look for the tools you are used to.

Hi all,
I was thinking how to improve situation with pyspatialite and spatialite 4
incompatibility. I have found that loading dynamic libspatialite module
instead pyspatialite is easier than I thought, at least in Ubuntu 12.04.
Here is working code example (python-pysqlite2 required):
from pysqlite2 import dbapi2 as sqlite3
conn = sqlite3.connect(:memory:)
conn.enable_load_extension(True)
cur = conn.cursor()
cur.execute(SELECT load_extension('libspatialite.so.5'))
cur.execute(SELECT ST_Length(ST_GeometryFromText('LINESTRING(30 10, 10 30,

print cur.fetchone()[0]
conn.close()
Has anybody tried to replace pyspatialite with python-pysqlite2 and
dynamic libspatialite loading ?
OK, I have tried following trivial replacement of pyspatialite with
pysqlite2 and it works great. Can we implement it?

Thank you in advance Roberto Hi Roberto, I'm assuming Textual Note is an Attribute Value. Do you need the value to happen as you draw the polygon? If you do, I don't know and you'll need to wait for someone else. If you want to write the $perimeter and $area into the attribute table after making your polygons, than I'd use the field calculator. The icon looks like a really small abacus. You can see it on the main icons, but also in the attribute table. You can use this to update all (or just the selected polygons) to show the right information. This is a better explanation than I could do: http://www.qgis.org/en/docs/user_manual/working_with_vector/field_calculator.html (not just in English, e.g. : http://www.qgis.org/it/docs/user_manual/working_with_vector/field_calculator.html ) If I've got it all wrong, please do try and make me understand. -ramon. ___ Qgis-developer mailing list Qgis-developer@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-developer
