[Qgis-user] Print Composer Filter

Hi, is it possible to filter a layer from print composer? I know an attribute layer can be filtered from composer and even it is possible to do some kind of filtering using Atlas, but I don't find a way to filter any feature from print composer. Any ideas? Thanks in advance.

Re: [Qgis-user] Saving values by a Python-Script in a PostgreSQL-Database

Hi Kai, you can get messages from PostGIS by calling commitErrors(): if vlayer2.commitChanges(): print('ok commitChanges') else: print('not ok commitChanges') for l in vlayer2.commitErrors(): print(l) The messages gave me a subtle hint that the attribute definition has to be

Re: [Qgis-user] Vertex tool not working on lines when style with 'attribute' assigned

Hi, I looked at the project you sent me.  If you add a rule with no filter, the vertex tool will work as all the lines are now shown. You can then hide these features by deselecting the "no filter lines" in the layer panel or by making the line transparent. So basically, the vertex tool

Re: [Qgis-user] QGIS and GeForce

I like what Nicolas said about this. On a Windows desktop I upgraded from a Nvidia Quadro P4000 graphics card (~$700)to a Geforce GTX 1060 graphics card (~$550) almost 2 years ago. I noticed a pretty good boost in performance, so I assume the latter card is better than the former, despite the

[Qgis-user] Antw: Developing an "Action" that shows changed value of a form-field

Well, it`s not an action, but I found a solution a home-made formular: from qgis.PyQt.QtWidgets import QWidget,QLineEdit,QPushButton,QDialogButtonBox from PyQt5.QtCore import * from PyQt5.QtGui import * def my_form_open(dialog, layer, feature): geom = feature.geometry() control =

Re: [Qgis-user] QGIS and GeForce

Hi, That is a good question I would like to see developers (which I am not) answer. Generally speaking, having a dedicated graphics card in a laptop will be an upgrade over a system that uses a cpu/gpu on the same chip, specially if the card has its own onboard memory. As you know, the

[Qgis-user] Developing an "Action" that shows changed value of a form-field

Dear users, for a vector-layer I would like to produce an action, that shows the changed value in a formular. E.G. I am editing a vector-point-layer, click on a point, the fomular is opening. I change a value (lets say the formular-field "z" had a value "test" and I change it to "test2"). Then

Re: [QGIS-it-user] Polilinea 3d da cad e colonna z

Fatto. Spero di non essere stata troppo prolissa. Se non è una cosa che pensate di implementare nell'immediato e pensate possa essere utile, piu in là posso dare una mano facendo una lista dei link da aggiungere per le funzioni, cosa che tornerebbe utile anche a me per studiarmele meglio. Martina

Re: [Qgis-user] problem with older version

Hi Boaz, When the layers didn’t appear when opening in the old version of QGIS, did you get any error message? Generally if a layer in a project cannot be found you get the opportunity to find it and reinstate it in the projects (handle bad layers). Maybe in the newer version of QGIS

Re: [Qgis-user] problem with older version

Hi, >From what I understand, he fails to open a 3.4 project in 2.18. Unfortunately, this is "normal". Nothing amazing if I may. While 2.18 files can be opened in 3.4 there's no guarantee for backwards compatibility, and there's lesser since the API break (from 2.x to 3.0) I'm not sure you can do

[Qgis-user] QGIS and GeForce

Dear all, I would like to know if it is strongly recommended to have a GeForce graphic card to use QGIS for every usage or if it is only necessary if doing complicated 3D modellations. As you surely know, the GeForce on a good Laptop raises the price and I wouldn't like to by one with a lower

[Qgis-user] Saving values by Python-Script in a PostgreSQL-Table

Re: [Qgis-user] Fix Geometries

I strongly agree, more than 1 year ago asked for translation to english to allow better review... but no power users reviewed the document, and we also were changing from 2.x to 3.x => that are some reason why it was never pushed forward. Probably we need a porting to 3.x and someone translating
