Re: [Qgis-developer] QGIS custom widgets with python plugins
Hi Stefan, To properly compile the UI file using pyuic4, you need to have the uic widget plugin installed. This is the file qgis_customwidgets.py that should be located in /usr/lib/python2.7/dist-packages/PyQt4/uic/widget-plugins/ This file can be either installed by the package python-qgis-common or using -WITH_CUSTOM_WIDGETS=TRUE if you compile your own QGIS (I suppose this requires a make install). Let me know if this helps.

Re: [Qgis-developer] User-contributed scripts/models for Processing
Hi Alexander, As an author of some scripts, I think this feature is a great opportunities to easily share useful snippets. I am not sure though we made enough publicity around it. I fear only power users will have the idea to open the branches of processing toolbox and discover there is a Scripts / Tools / Get scripts from collection. I have no idea though how to improve this. I would prefer to use Github bugtracker, but I have no strong opinion about it. I agree we should warn the users and tell them the provided scripts are like extensions, delivered as is.

So we have two options here: 1. create special category in QGIS bugtracker 2. use GitHub bugtracker Another thing, as this scripts and models (well, the biggest part of them) actually contributed by users, core developers are not responsible to their bugs.

[Qgis-developer] Core Python plugins and their dependencies
Hi all, do we have any policy about dependencies of core Python plugins? Current situation is a bit messy and confusing. DB Manager depends on psycopg2 and pyspatialite, but we does not ship this packages into QGIS source tree. Same for Processing, it contains several algorithms that require matplotlib and we does not bundle matplotlib in QGIS source tree. And it is fine, as user can easily install this packages using package manager or pip. On other hand MetaSearch adds 7.4 Mb of dependecies to QGIS sources, while in most Linux distributions this packages available from repositories or from PyPI. Even under Windows this packages present in OSGeo4W installer. I think it would be good to have clear policy on this. Personally I think that we should avoid including Python dependencies in QGIS sources and if plugin requires some 3rd party libs, we can make it disabled by default ot even optional (so it will be compiled and installed only if all necessary dependencies already available).

[Qgis-developer] QgsMapRenderer and QgsMapSettings relation
I've found code dealing with aspect-ratio adjustments in two places: QgsMapSettings::updateDerived() and QgsMapRenderer::adjustExtentToSize() As I'm trying to deal with viewport rotation, any such duplication makes the work harder as things need to be changed in many different places. Similar thing happens for QgsMapRenderer::setExtent, which is also present in QgsMapSettings. As QgsMapRenderer is actually initialized with a QgsMapSetting object, should it always use services exposed by that class rather than re-doing things locally ? Or what am I missing ?

Re: [Qgis-developer] Problems with developing custom c++ qgis application with QtCreator and MSVC2008 on Windows
Thanks for the link. I have checked out the C++ code example on Github before. But it is just kinda frustrating to see that the examples are mostly from 5 years ago and so much have changed. Also, for the add_raster_layer example in particular, I setup the whole project on my computer and try to add a layer, it reports an invalid layer. So right now, I have no idea what to change in order for the code to work.

How are you initializing it? Or do you just declare it and add a raster layer directly? Because from that link, I see the addRasterLayer method is a pure virtual function and QgisInterface is abstract class. I want to add this layer into a QgsMapCanvas, how should I do that?

Re: [Qgis-developer] [plugins] refreshing canvas
I've tried to add the canvas.repaint() with my canvas.refresh(), and it seems to work ! Thanks !

I get this problem since the beginning of the development on QIGS 2.2. It is for me a random problem, because I can't say why I get these white canvas. But, when I get it I save the projet with the white view, and when reloaded, the canvas is still white. I've played with canvas.refresh(), canvas renderer flags and even with canvas.freeze(). I can't understand the behaviour I get, maybe I have a wrong usage of the properties above. I also thought about triggerRepaint()...

[Qgis-developer] Contrast Enhancement
Hi all, I have some problems to apply new stretching values to my layer I have a function which allows to adapt the stretching of my image without the raster layer properties dialog. When I open an image with my plugin, I display it on the canvas, I open my own histograms, and I can move the min max stretch of the 3 displayed bands. It works well. But, when i save the project, i reopen it, I want to change the image stretching, it does nothing. The values are set, but it seems that the layer renderer is not updated. Here is my stretching code : print canvas print layer :, theRasterLayer # type of layer : raster, vector, other typeOfLayer = theRasterLayer.type() dataProvider = theRasterLayer.dataProvider() # the layer has to be a raster layer if typeOfLayer == 1 : if (theRasterLayer.rasterType() == 0 ) and theRasterLayer.renderer(): [...] elif theRasterLayer.rasterType() == 2 and theRasterLayer.renderer(): min_red, max_red = values[0] min_green, max_green = values[1] min_blue, max_blue = values[2] redEnhancement = QgsContrastEnhancement( dataProvider.dataType( 0 ) ) greenEnhancement = QgsContrastEnhancement( dataProvider.dataType( 1 ) ) blueEnhancement = QgsContrastEnhancement( dataProvider.dataType( 2 ) ) #set stretch to min max redEnhancement.setMinimumValue( min_red ) redEnhancement.setMaximumValue( max_red ) greenEnhancement.setMinimumValue( min_green ) greenEnhancement.setMaximumValue( max_green ) blueEnhancement.setMinimumValue( min_blue ) blueEnhancement.setMaximumValue( max_blue ) redEnhancement.setContrastEnhancementAlgorithm(1) greenEnhancement.setContrastEnhancementAlgorithm(1) blueEnhancement.setContrastEnhancementAlgorithm(1) print blue enhancement, blueEnhancement print blue max, blueEnhancement.maximumValue() print blue min, blueEnhancement.minimumValue() theRasterLayer.renderer().setRedContrastEnhancement( redEnhancement) theRasterLayer.renderer().setGreenContrastEnhancement( greenEnhancement ) theRasterLayer.renderer().setBlueContrastEnhancement( blueEnhancement) theRasterLayer.triggerRepaint() print theRasterLayer.renderer().blueContrastEnhancement() print theRasterLayer.renderer().blueContrastEnhancement().minimumValue() print theRasterLayer.renderer().blueContrastEnhancement().maximumValue() canvas.refresh() canvas.repaint() In my case, the canvas, is the main canvas, I have checked I work on the good one comparing the print canvas and the python console with iface.mapCanvas(). I know : * both cases run this function. * the minimum and maximum values of contrast enhancement are the same in my two prints (before and after the setXContrastEnhancement) (so the theRasterLayer.renderer().blueContrastEnhancement() seems to be well set) * these values are the good ones * they aren't displayed in the raster layer properties dialog * my raster layer source is ok * when i do these steps on the QGIS python console with the layer iface.mapCanvas().currentLayer() which points to the same file, it works layer = iface.mapCanvas().currentLayer() blue_en = QgsContrastEnhancement( layer.dataProvider().dataType(2)) blue_en.setMinimumValue(150) blue_en.setMaximumValue(350) blue_en.setContrastEnhancementAlgorithm(1) layer.renderer().setBlueContrastEnhancement(blue_en) layer.triggerRepaint() What have I missed ?
