To get the behaviour the only thing you have to do is to call map tool's setAction() or setButton() method. That will cause that when the tool is activated/deactivated, the associated action or button will get selected/delected. (This behaviour is implemented in QgsMapTool::activate() and QgsMapTool::deactivate() so that's why it's good to call them also if you reimplement these methods.) > But still some details were not clear for me: for example it's not clear > for me if you must make a new 'tool' when you want to make a plugin > which does something with a click in the mapcanvas.

I should start this page myself maybe ... Well, some of those are already on PythonBindings wiki page, however some are probably missing :) I'll see what more could I add. For sure you can start a list of such simple tasks, we could address them with the code snippets. > ps (referring to my buffer questions a while a go) if you point me to > some 'easy' buffer algorithms, I'm ready to give C++ a try :-) ) Uhm, starting from r7986 you can use QgsGeometry::buffer() function that does exactly what you need :-) Obligatory snippet: gLine = QgsGeometry.fromPolyline( [ QgsPoint(1,1), QgsPoint(2,2) ] ) # buffer with distance 0.5, use 5 segments to approximate curves gBuffer = gLine.buffer(0.5, 5) print gBuffer.asPolygon() Enjoy!

My 'problem': I've build a sort of XY-Info tool plugin, like the raster info plugin in the repository. But mine is suppossed to be a tool like the zoom tool, or the select tool: you click on the tool/plugin-button, the button gets activated/surpressed/darker, and keeps in that state until you select one of the other (zoom, select or info) tools.

Volunteers? :) > Well, but you still must know Qt to do anything more complicated than > just a hello world plugin. I'm a sort of beginner. Using the copyright plugin I hacked by the html-image-map tool (which is in the repository) using trial and error, and was able to use Qt etc etc (see http://www.duif.net/qgis). But still some details were not clear for me: for example it's not clear for me if you must make a new 'tool' when you want to make a plugin which does something with a click in the mapcanvas. Another question is the one about keeping a button 'activated'. My idea is to make some 'plugin-stubs' for different kind of simple plugins: eg starting with a very simple plugin which does not have an interaction with the map, to a tool like the xy-info tool which must handle a mouse click, and finally your copyright-plugin which was really helpful for me. But maybe a plugin stubb is not what I'm looking for: it's either to complicated because you want to make it technically useful, or it's to simple to be functionally useful. The idea was to hand beginners the first steps to to a really easy plugin. But maybe we need a code-snippets wiki page with questions like: - I want to keep de plugin button activated - I want to get hold of the active geometries of the active layer - I want to loop through all geometries of this layer - How do I test the type of a geometry - How do I make pixel coordinates from world coordinates and vice versa - How can I add a label to a (new) layer - How can I add a new geometry to a layer - How can I keep some project info by writing it to a project file etc etc. ... I should start this page myself maybe ... Thanks, and people should really look into the blog and wiki for your examples, they are really helpful!

Re: [Qgis-user] gps problem
Hi QGIS doesnt have language bindings for java so I guess you are calling qgis as a system process? The screenshot command line option is using the same (gui based) application binary as QGIS desktop - hence the possibility for the visual side effects. For a more robust solution I would suggest making a simple libqgis_core based command line app to load your maps and create an image output. There are a number of examples for python and c++ available, and the tests/src/core unit tests have additional routines that can be adopted as the basis for such a simple command line app. Regards Tim 2008/1/16, Tolga Tanriverdi <[EMAIL PROTECTED]>: > I'm using java for my project > > -Original Message- > From: Tim Sutton [mailto:[EMAIL PROTECTED] > Sent: 16 Ocak 2008 Çarşamba 11:29 > To: Tolga Tanriverdi > Cc: qgis-user@lists.qgis.org > Subject: Re: [Qgis-user] gps problem > > Hi > > 2008/1/15, Tolga Tanriverdi <[EMAIL PROTECTED]>: > > > > > > > > > > Hi > > I'm new to whole qgis thing and I'm trying to develop a gis application > > with using qgis but I want to use qgis as a command line tool > > Which language are you developing with - python or c++? > > Regards > > Tim > > > > so I have created the project with qgis gui and saved it as a qgis project, > > now what I want is to send qgis a gpx file for using it's gps addon and take > > the snapshot of the project as a png file with --snapshot parameter > > however I couldnt find any way to give gpx file name as a project parameter > > does anyone know how can i do that ? > > My second question is when I called qgis with --snapshot parameter a gui of > > qgis appears for an instance is there a way to stop this? > > Thanks > > > > > > > > Tolga Tanrıverdi > > > > Aydın Yazılım ve Elektronik Sanayii A.Ş > > > > Ağ Sistem Mühendisi > > > > (0312)2101565-134 > > > > > > ___ > > Qgis-user mailing list > > Qgis-user@lists.qgis.org > > http://lists.qgis.org/cgi-bin/mailman/listinfo/qgis-user > > > > > > > -- > Tim Sutton > QGIS Project Steering Committee Member - Release Manager > Visit http://qgis.org for a great open source GIS > openModeller Desktop Developer > Visit http://openModeller.sf.net for a great open source ecological > niche modelling tool > Home Page: http://tim.linfiniti.com > Skype: timlinux > Irc: timlinux on #qgis at freenode.net > > > Bu e-posta, mesaji alici kisminda belirtilmis olan kullanici icindir.
