[Qgis-developer] road graph crashes qgis for spatialite layers

[Qgis-developer] file browser plugin
Hi all, I would like to thank Nathan Woodrow for his very useful file browser plugin! Nathan, it will support also rasters? I noticed also that under Windows the folders are ordered alphabetically while under linux it seems random. Other features that would be great to have (and that maybe you have already planned) are a finder and a filter for files and folders. thanks! -- Giovanni -- ___ Qgis-developer mailing list Qgis-developer@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-developer
Re: [Qgis-developer] file browser plugin
Thanks for the feedback Giovanni. Glad you liked it. Support for rasters should be pretty easy to add, I'll see if I can add something tonight or tomorrow. Yeah I didn't notice the sorting difference until I installed it on windows to test today. I think I will just sort the list before I add it to the combo box. Thanks for the idea for the file search, I'll see what I can come up with. - Nathan On Mon, Jan 31, 2011 at 8:15 PM, Giovanni Manghi giovanni.man...@gmail.comwrote: Hi all, I would like to thank Nathan Woodrow for his very useful file browser plugin!

I have a doubt regarding this bug that is, While creating a GPX layer, Can the user has privilege to move the feature or using Node tool ? The node tool is disabled because GPX provider doesn't implement modification of existing geometries as of now. You can fix this by implementing vector data provider's changeGeometryValues() method in GPX provider and adding ChangeGeometries capability.

[Qgis-developer] road graph export
Hi all. If I export the shortest path to a new temporary layer, it is saved to EPSG:4326 - WGS 84 instead of current project projection. I think this is suboptimal. Moreover, visually the path does not seem the shortest (but I have to do more formal testing). Finally, when saving the image, the red path is not saved. Sorry for being so boring.

[Qgis-developer] add WMS layer
Hi all. I have seen that the recent rearrangement of vector loading button has included WMS among the vectors. I think this is inappropriate. I suggest moving it to a load raster button, or put it together with WFS in a load web services button. In the first case, WFS could appropriately be moved to the load vector button.

[Qgis-developer] Known problems with QGIS
Hi all, After an intensive use of QGIS 1.6 (binary installations on linux, MAC and windows), I've found the following problems to be of particular operational concern: 1. Histogram tool for raster layers: I think it only works right for Unsigned Byte images, for sure it is wrong if negative values are present and it is always a poor graphic. The histogram is essential for a sounded stretching (which in turn is essential for good display) and important to understand the distribution of the variable, the presence of outliers etc. 2.While 1-Band Raster Color band and Colour Scale Bar go in the right direction, these type of tools must be integrated in the Properties dialog. A reasonable key color table should show up by default and raster layers of qualitative variables (i.e. land cover maps) should have appropriate tools for being displayed. 3. Vector operations are too slow as soon as layers are moderately complex. 4. Tools for the display of quantitative fields is still insufficient. Quantiles, natural breaks etc should show on a histogram and the user should be able of, at least, setting the meaningful min and max values (these algorithms fail in the presence of outliers) and best being able to apply interactive fine tuning. Some transformations (i.e. logarithmic) should be possible without having to actually calculate the new field. 5. Point sampling tool: this tool should join the attribute table (or let the user select which fields to keep, or at least keep an ID field) of the original points layer with the one(s) of the layer(s) from which the values are to be extracted. Currently the user has to create an ID for the original point layer and for the resulting point layer and then run a join operation (3 more operations). Point sampling tool is very important to merge information between vector and raster layers for further analysis. 6. QGIS crashed from time to time (sometimes calculating the histogram). As crashes were suffered by inexperienced users, I've not been able to collect detailed information. RasterCalc has performed very well and has been very useful for students to understand spectral vegetation indices. An if() operation is missing but is coming... I think all these issues have filled tickets, but wanted to list them together. As browsing the ticket system is kind of complex for potential new users, we should include a list of Known Problems including the most important ones in each release. QGIS is good, no need to hide problems. Hopefully some of the listed problems will be addressed during the next hackfest and hopefully I'll be able to attend to help out somehow. Thank you all for your work. Agus ___ Qgis-developer mailing list Qgis-developer@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-developer
[Qgis-developer] Problems using QgsVectorLayer::selectedFeatures()
Hi List, I'm developing an application using the QGIS API. At this point, I need to replicate the QGIS functionality for merging features in a given layer. I copied some parts of the code from qgisapp.cpp, but I have some problems. In short, I receive an abort from the compiler when the method exits at the point that the QList destructor is called. Do I have to take special considerations calling this method? The relevant code is: QgsFeatureList featureList = this-currentLayer-selectedFeatures(); //get QListQgsFeature Where this-currentLayer is a QgsVectorLayer.

Re: [Qgis-developer] file browser plugin
Hi All, I have now added raster support for my file browser plugin, should be upgradeable in the plugin installer as 1.2. I have given it limited testing, as I don't have a lot of raster files to test it with. If you find any bugs don't hesitate to let me know. - Nathan 2011/2/1 Giovanni Manghi giovanni.man...@gmail.com Hi Germán, Giovanni, do you mean something like this [1] (Load Them All plugin)? yes, something like the filter in your plugin. In this case to allow show only the files/folders with a certain pattern.
