Re: [Qgis-user] QGIS releases announced too early IMHO

Despite being a non-Mac user, I respectfully disagree Mainstream users should not have to wait until packages for ALL systems have been built. Some minor ports may take someone a while to complete - & others need not be waiting on this. A QGIS release announcement is NOT a promise that every

Many thanks to James, Brent, Alexander and Andreas for the suggestions. It looks like PostGIS offers the best option for the limited complexity of the solution. PostGIS is not something I had worked with before or considered. After doing a bit of research and referencing the code/process Brent of

Not tested, but what about using the v.to.db function (grass function, does not seem to be available in the toolbox, but you could have a look at the GRASS tools addon). With this function you can upload category numbers of left and right area, to an attribute table of boundaries common for the ar

I assume that it's just saved as a string when you fill it in designer? So in this case you will need to check the value itself (with tricks like casting to an integer and if unsuccessful casting to a float or similar). Matthias On 03/02/2016 04:17 PM, matteo wrote: > Hi Matthias, > thanks for t

Re: [Qgis-user] force data type in QTableWidget in QGIS plugin

Hi Matthias, thanks for the super quick reply. So you are saying that I can manually set the item data using setData(...) and get the type of that data by data().type() But in my case the first row of the QWidgetTable is already filled with some custom values (I filled it Qt Designer). When I ru

Re: [Qgis-user] forse data type in QTableWidget in QGIS plugin

Hi Matteo, If you check for QTableWidget::item(...) you see that it returns a QTableWidgetItem*, so that's what you check the type of which you specified yourself when creating the item. Either construct the items with an integer you want (this does not need to match the QVariant types' id) Or us

[Qgis-user] forse data type in QTableWidget in QGIS plugin

Hi all, I'm struggling with a problem in a QGIS plugin. Very briefly, in Qt Designer I have created a QTableWidget with some rows. The first one is filled with some default values (int and floats). I did not find a way to get a list of the data types in the python script. This in a piece of code

Re: [Qgis-user] Layer driven Atlas

Thomas, The other thing when you use virtual layers: did you introduce a unique column that can be used as primary key, enabled and entered a "Unique identifier column"? Otherwise I wouldn't be surprised that @atlas_featureid doesn't work. Andreas On 2016-03-02 14:58, Neumann, Andreas wrote

Re: [Qgis-user] Layer driven Atlas

Hi Tom, @atlas_feature returns a full feature - with geometry and attributes - similar to a full database record type. With this feature you could extract the geometry and the attributes. You probably want @atlas_featurenumber and @atlas_totalfeatures ? @atlas_featureid should return the uniq

Re: [Qgis-user] Layer driven Atlas

Hi Andreas That’s excellent, thanks so much, I never thought about joining tables. The virtual layer works really well. Again I’m not sure if I’m doing something wrong or a bug but some of the atlas variables aren’t working as expected: atlas_feature and atlas_featureid return and 0 respectiv

Hi Nathan, You state that "There is no "official" release until the banner is changed on qgis.org and announcement is made on the mailing lists/twitter, etc.". Well, that has happened now, but the KyngChaos site for Mac OSX still has 2.12. That is NOT a negative comment on th
