[Qgis-developer] Impossible to upload and share a plugin on QGIS plugin repository
Hi all I'm tring to upload and share my first plugin at [1] but encountered an error I don't really understand. It says: *There were errors reading plugin package (please check also your plugin's metadata). Cannot find __init__.py or metadata.txt in the compressed package: this does not seems a valid plugin (I searched for help/__init__.py and help/metadata.txt)* I have __init__.py and metadata.txt files but they are in the main folder (I use Plugin Builder plugin) and none of the plugin folders I looked at has such files in help folder. So, why is it looking for these files in the help folder? What did I make wrong? Is it a bug? and if not, what should contain these files? Some help? Thanks a lot.

Re: [Qgis-developer] Get signal on edited feature ?
Hello, For the first question, I think you have done something like logFeaturesAdded(Idofmylayer, features) instead of doing self.logFeaturesAdded(Idofmylayer, features).The function you created has three args : self, layerId, addfeatures. When using it you should give him three args. The second expression has three arguments not the first one. Try that. for your second question, give a look at self.iface.zoomToActiveLayer(), after having activated your layer. There may be another way but... I think one good way to learn how to use all this is to make tests with the qgis Python Console and you'll quickly find the best functions to call. 2014-07-31 11:08 GMT+02:00 dandrigo : > Hello, thank for your reply. > > 1/ For my pyqgis plugin 2.2, i try to > --- > def logFeatureAdded(self,layerId,addfeatures): > message = str(layerId) + " has features added: " > for feature in addedFeatures: > message += str( feature.id() ) + ", " > QgsMessageLog.logMessage(message) > QApplication.beep() > > > When i try to add a feature, this following error message appears: > > TypeError : logFeaturesAdded() takes exactly 3 arguments (2 given). > > 2/ Always for my plugin, i can load a vector layer succesfully.

[Qgis-developer] Export atlas composition in python console to a single PDF file
Hi All, A couple of hours I'm trying without success to do something so I ask for your help. I would like to export as PDF (in a single file) an atlas composition within Python Console. I don't find how to do. All I obtain is either multiple PDF files corresponding to each iterated feature of the coverage layer or a single feature corresponding to the last iterated feature. Where should I look at, please? And more generally, where can I find the code used by a tool such as "Export Atlas to PDF file" in the composer GUI (atlas menu)?

[Qgis-developer] What does mean "empty tables" in "attribute table" item properties in a print composer?
Hi all, I try to understand the use case of empty tables in print composer and am still confused. Create a new print composer and add an attribute table item set its height enough to show more rows than the maximal values of features you set. Add a second frame to this item. Is this second frame considered as "empty table" (as no feature attribute will be displayed inside)? According to the answer, I think I'll have many other questions about the options in "empty tables" combo box. The only "empty table" I found in my tests is when the first frame displays nothing (because "maximal rows" is set to 0 or "show only visible features within a map" is checked and nothing matches). Is it the only situation? Can somebody explain to me, please? Thanks in advance.

Thanks Nyall. This is what I suspected. Then, none of the "empty tables" options should work on the frames in the example above, right? But actually, "Draw empty cells" option does have effect on them.

Re: [Qgis-developer] What does mean "empty tables" in "attribute table" item properties in a print composer?
Indeed, this a desirable behavior: user may want to show empty rows when there are not enough matching features. This is what I was looking for when using this option. But having this one working for a table and none among the three other options is a bit confusing for the user. I spent at least an hour on testing why these options didn't work and I'm afraid I won't be the last. Don't you think that "draw empty rows" can be a separate option (may be a checkbox)? It'll have its effects on every frame with too higher rows for the features. The other three options in the combobox will work only when there is no row (on real empty tables). 2014-10-09 13:28 GMT+02:00 Nyall Dawson : > On 9 October 2014 08:53, Junior Delaz wrote: > > Thanks Nyall.

[Qgis-developer] Impossible to keep QGIS 2.4 while updating QGIS master (osgeo4W nightly build)
Hello, I use OsGeo4W to install both QGIS stable and master releases. Due to the bug of QGIS 2.6.0-1 that crashes QGIS and ruins some older project file, I decided to not yet upgrade to 2.6 (and keep 2.4) but still update nightly builds. The first time I got 2.7, I choose to keep 2.4. After the install process, I was unable to run QGis 2.4, getting the error message attached when launching either the shortcut or the qgis.bat file in install directory. Two days later, after updating nightly build , QGIS 2.4 worked fine and stopped again at the next nightly build. Since, reinstalling QGIS 2.4 in osgeo4w install process doesn't fix it, the only usable release remains the Master. Is this a bug or is it impossible to install both master and "not the latest stable" releases through osgeo4W? If a bug, should I file a ticket on qgis hub or elsewhere? Any idea how I can get back a working QGIS 2.4? I'm on Windows 7 64 bits but I got the same bug on Windows 8 32 bits. Thanks. ___ Qgis-developer mailing list Qgis-developer@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-developer
Re: [Qgis-developer] Questions about Dialog for Select by Expression
Hi All Lene, The height of the expression frame should indeed have a minimum value, to avoid closing it. But this is not a new behaviour. In QGIS 2.4, you could already close totally this frame if you drag down enough. I think it's a bug and you can fill a ticket unless it's an intended behaviour (and it would be nice if the dev can explain why such choice - thanks). About syntax coloring, I have it work as expected here but I'm on 2.6.1 (haven't tried 2.6.0). Maybe, it's already fixed or it's an OS issue (I'm on Windows 7 64bits, Osgeo4w advanced install). For the last one, I agree with you, we should have kept "load unique values" and "All" instead of "load values" and "All unique". The first one seems more comprehensive to me and everybody gets that the "unique" term applies for "All" and "10 samples". It may be confusing now, having "unique" only on "All" button.

[Qgis-developer] Retrieve value from another layer related to its localisation
Hi all, I have two shapefiles : a line one (called "section") and a point one (called "station") shapefiles. The line shapefiles has fields like ID_section, ID_first, ID_last The point file has an ID_station. All these define a kind of network where a section begins on a station and ends up at another station. What I need to do is to fill : - section ID_first field with the ID_station of the station that is the closest to the beginning of the section - and section ID_last field with the ID_station of the closest station to the end of the line. I can obtain this result while combining many analysis tools and plugins (QChainage, Spatial_Join...). I know how I can do it. There might be a way with processing tools and if somebody has an idea, I'll be glad to know it however. But what I'm really wondering is if it isn't directly possible to fill these fields in the Field calculator using all the nice functions we have. Indeed, QGIS 2.6 and RefFunctions plugin give relational fonctions to retrieve values on a specific layer according to its fields, features values or localisation. I tried many combinations with db_query, geomnearest, geomRedef, xat/yat, buffer, geometry, within , attribute (not all at the same time :) ) I'm pretty sure it's possible but I can't find. And I don't want to lose all my hair... Does anybody know how I can retrieve in a line shapefile's field the value of the point feature that is the closest to the first vertex of this line, within the field calculator?

Re: [Qgis-developer] [Bulk] Re: [Qgis-user] Retrieve value from another layer related to its localisation
Thanks Enrico for your reply and for the plugin.
I was aware of RefFunctions and has already used it for relational
questions. And I agree with Jean that such functions (and others of your
plugins) might be core functions. I've moreover reported a feature request
to improve usability of all this #11680 <https://hub.qgis.org/issues/11680>.
And I tried it again this time. but the main problem is I don't want to
retrieve field value of the nearest point to my line geometry. I want to
retrieve field value of the nearest point *to the first vertex* of my line
geometry. While using just geomnearest, i'll get only the nearest point to
the whole line. It may be the point at the beginning or the one at the end
of the line, I can't know.
What I did is to create a point file containing my vertices and then use
refFunctions to get the nearest station ID.
But, isn't it possible to do the request without the step of creating new
point file? Using in the condition "being nearest to the geomfromWKT('POINT
(xat(0) yat(0)) ') of line feature"?
How can I write in the field calculator of a line layer such function :
dbquery ('mypointlayer', 'pointID', 'the condition is to be the nearest
point to the first vertex of the line')? Or dbvalue? Is it possible to
combine reference functions with others?
And more generally, are Reference functions conditions intended to be only
internal to the target layer or can I use values/fields from the source
layer? If latter, how can I refer to the source layer in the expression?
Thanks

Re: [Qgis-developer] [Bulk] Re: [Qgis-user] Retrieve value from another layer related to its localisation
Ok, this is somehow what I did. With QChainage plugin, no need to create
new fields and csv table. It directly creates the point geometry layer
corresponding to xat(0)/yat(0) and xat(-1)/yat(-1) with $id field, when
well setting.
I also assume that what I was trying to do directly within the line layer
field calculator is not (yet) possible.

[Qgis-developer] Pyqt4 : which signal is sent when dialog comes to foreground?
Hi, I'm working on a Python plugin for QGIS and need your help to do something. I'm a beginner in Python and C++ and just used plugin-builder for the architecture. My main dialog is a non modal one and does list print composers in the project. It means that while it's opened, user can delete or create composer. What I'd like is, when user calls back the dialog to foreground, it automatically updates the list of composers. I already have the function to update but don't find which signal to use. I can add a button to do this but better if it can be done transparently... I've read about defining a custom showEvent function but can't understand where to put it and what inside. If somebody can give some tips... Thanks in advance, DelazJ ___ Qgis-developer mailing list Qgis-developer@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-developer
Re: [Qgis-developer] Re : [Qgis-user] Pyqt4 : which signal is sent when dialog comes to foreground?
Matthias, Thanks. I just give it a try it and all goes well with composerAdded. But not really well with composerWillBeRemoved signal. The first deletion in the composer manager does nothing and deleting a second composer does remove the first one in my list. and so on... My update function should be rewritten I think. I'll try to see how improving it and may (surely) ask again for help (if needed). While seeking information about composerWillBeRemoved, I found a composerRemoved [1] [2] signal (that doesn't appear in the API doc) and without being able to use it. :( [1] https://github.com/qgis/QGIS/blob/master/src/app/composer/qgscomposermanager.cpp (line 48 [2] https://github.com/qgis/QGIS/blob/master/src/app/qgisapp.cpp (line 5601) Another thing that may not be related : what the deletePrintComposers function (https://github.com/qgis/QGIS/blob/master/src/app/qgisapp.cpp line 5698) is for?

Re: [Qgis-developer] Re : [Qgis-user] Pyqt4 : which signal is sent when dialog comes to foreground?
Hi, I do understand nothing. After I read your message, Matthias, I told myself that using QT. QueuedConnection should be the easiest way. Then i wrote self.iface.composerWillBeRemoved.connect(self.refreshList, Qt.QueuedConnection) But each time i delete a composer, QGIS crashes. So I've spent the week on reading about Qt.QueuedConnection and then signal and slots, function partial, QSignalMapper, sender trying to understand how I can catch the sender and manage to update my list. All this without success in the code. And today, I tried again Qt.QueuedConnection, QGIS crashed. Without any changes, I tried again and it worked and continues to work. Adding and deleting composer in the composer manager echoes in my list. I hope it will remain like that. But now I realize that I didn't take into account the renaming of a composer. :( I think I'd wisely keep the refreshlist button unless someone tells me how I can reach the composer manager dialog programmatically. So that I will try to synchronize my list with its widgetlistitems...

Thank you Matthias for your perseverance. It's very helpful and encouraging for beginners.

But why does composerRemoved not work?

Re: [Qgis-developer] Re : [Qgis-user] Pyqt4 : which signal is sent when dialog comes to foreground?
Ahh indeed, you are right... I should have paid attention to the Class in which I found the signal. But I was too obsessed by composerWillBeRemoved that I thought I was still in QgisInterface. If it can be added to QgisInterface, why not? Any idea about my remark on Qt.QueuedConnection and architecture 64bits vs 32bits? In the meantime, I think I'll keep the refresh button and find a simple way to deal with the case user doesn't refresh before executing (it might not be that hard :) ). And in this case, I also keep compatibility with all 2.x releases. 2015-04-08 0:16 GMT+02:00 Matthias Kuhn : > It's in QgisApp but not in QgisInterface. > > It is only used internally by the app (in the composermanager for exactly > the same purpose as you are trying to use it for AFAICS). > Anyway, I don't see any reason not to make this available on the public > interface as well... > > > On 04/07/2015 11:51 PM, Junior Delaz wrote: > > But why does composerRemoved not work?

No I guess it's an issue of some different version or some low-level compiler differences. If it crashes on one platform, don't use it. It's probably trying to access a deleted object. It's not a bug but likely rather a misuse. ___ Qgis-developer mailing list Qgis-developer@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/qgis-developer
[Qgis-developer] Designing a plugin : TypeError raised on MacOS machines but not on Windows
Hi all,
I'm testing a plugin I created with Plugin Builder on different platforms
and encounter a problem I can't understand. The same piece of code works on
Windows machines but not on MacOS ones where I get this error message.
Traceback (most recent call last):
File
"/Users/harrissou/.qgis2/python/plugins/MapsPrinter/maps_printer.py", line
369, in saveFile
progress.setLabelText(self.tr( u'Exporting maps from {}…'.format(title)
))
File
"/Users/harrissou/.qgis2/python/plugins/MapsPrinter/maps_printer.py", line
87, in tr
return QCoreApplication.translate('MapsPrinter', message)
TypeError: function takes exactly 5 arguments (1 given)
QCoreApplication.translate is called in a tr function that is generated by
Plugin Builder :
def tr(self, message):
"""Get the translation for a string using Qt translation API.
We implement this ourselves since we do not inherit QObject.
:param message: String for translation.
:type message: str, QString
:returns: Translated version of message.
:rtype: QString
"""
# noinspection PyTypeChecker,PyArgumentList,PyCallByClass
return QCoreApplication.translate('MapsPrinter', message)
Each time I run on MacOS, I get the previous error. But I remark that I
don't get this error if in the saveFile function, instead of
progress.setLabelText(self.tr( u'Exporting maps from {}…'.format(title) ))
I put
progress.setLabelText(self.tr( 'Exporting maps from {}…'.format(title) ))
All goes well except that I can't manage special characters and therefore
can encounter an UnicodeEncodeError error (on both platforms). But it never
complains about QCoreApplication.translate function.
Traceback (most recent call last):
File
"/Users/harrissou/.qgis2/python/plugins/MapsPrinter/maps_printer.py", line

Any idea is welcome.
