Re: [QGIS-Developer] Error compiling qgsapplication.h

2018-04-11 Thread Magdaleen Ballot

Good evening Jurgen,

Thank you very much for your effort. I manually applied the changes in the
patch. I also changed the FindQGIS.cmake to this one:
https://github.com/qgis/QGIS/blob/master/cmake/FindQGIS.cmake
and even replaced content of qgsapplication.h with
https://github.com/qgis/QGIS/blob/release-2_18/src/core/qgsapplication.h

I still get the same error.

But indeed as the compiler says, in none of the functions below does the
parameter have a type. They seem to member variables  or am I ignorant
on a C++  shorthand:
static QObject* ABISYM( mFileOpenEventReceiver );

static QStringList ABISYM( mFileOpenEventList );

static QString ABISYM( mUIThemeName );

static QString ABISYM( mPrefixPath );

static QString ABISYM( mPluginPath );

static QString ABISYM( mPkgDataPath );

static QString ABISYM( mLibraryPath );
static QString ABISYM( mLibexecPath );
static QString ABISYM( mThemeName );
static QStringList ABISYM( mDefaultSvgPaths );
static QMap<QString, QString> ABISYM( mSystemEnvVars );

static QString ABISYM( mConfigPath );
???

Any further help or education will be much appreciated.

Kind Regards
Magdaleen Ballot

[QGIS-Developer] Error compiling qgsapplication.h

2018-04-10 Thread Magdaleen Ballot

Hi,

I am maintaining a c++ Radio Planning Plugin for QGis, QRap (www.QRap.org.za
).

I am trying to compile in Ubuntu 18.04, using QGis  2.18 (the libqgis-dev
version is 1:2.18.18+28bionic. The compiler I am using is GNU 7.3. The
error messages are below.

I had the same problem under Ubuntu 16.04 using Qgis 2.14 and c++ 5.

The last version I could complie successfully was QGIS 2.8.

Can somebody please help.

Kind Regards
Magdaleen Ballot

[Qgis-developer] QRap plugin: Mouse Click not capture

2016-10-17 Thread Magdaleen Ballot

Good day,

I am the sole developer left on the development of the QRap plugin 
(www.QRap.org.za / https://sourceforge.net/projects/qrap/ ). As this is not 
even my main focus, I tent not to update so often as only sync with LTR 
versions. 

Until QGis 2.8 the mouse clicked worked fine, but when I updated to 2.14 it no 
longer worked. Attached is the MouseEvent code I use. I originally had it 
inherit from QqsMapTool and then from QgsMapToolEmitPoint ... both works on 
QGis 2.8, but neither on 2.14.   I tried using QgsMapToolEmitPoint directly but 
it said 
QgsMapToolEmitPoint::canvasClicked(QgsPoint&,Qt::MouseButton) does not exist 
when I run it ... it does not both in 2.8 and 2.14. 

I can confirm that MapCanvas()->SetMapTool run sucessfully  (I caught the 
mapToolSet signal ... )

Does any of you with years of experience perhaps have a pointer that would help 
me resolve it. 

Kind Regards
Magdaleen Ballot

PS: Why is QRap not in the QGis repository ... because it is huge, and I still 
want to get rid of Poco (which is used for XML parsing and replace it with a Qt 
component)

[Qgis-developer] Fwd: Q-Rap plugin

2013-09-20 Thread Magdaleen Ballot

Hi,

I am currently th only active developer on Q-Rap, a Radio Planning plugin for 
QGis (source code at http://sourceforge.net/projects/qrap/). I recently updated 
it to work with Qgis version 2 (the upgrade on the Ubuntu repositories catch me 
a bit surprised as the Web-site still only talks about version 1.80). 

None the less, my main problem is that I am having trouble to have Q-Rap 
stick: 
It loads successfully, however when I close Q-Gis down and open it up again the 
tool bar is not there.BRQ-Rap is still selected, but it would seem like the 
constructor and initGui is not run again when I open up QGis. so now I have to 
un select the Q-Rap plugin and selects it again ... and then it loads.
I had another look at the plugin-template and some other plugin implementations 
in the source code, but I BRreally don't get it. Q-Rap creates its own new 
ToolBar on the QGis-interface.
(I had this problem in 1.8 as well ... in version 1.7 it worked fine)

Is this a bug in QGis or am I blind to what I am doing wrong?

On another topic;
On the Q-Rap mailing list I got the following message for Giovanni:

 http://www.qgis.org/api/INSTALL.html ( http://www.qgis.org/api/INSTALL.html 
)
 ( http://www.qgis.org/api/INSTALL.html ) I doubt anyway that you will be able 
 to make qrap works with the
 latest QGIS source code as it does not seem to have been updated recently.

 QGIS C++ plugins should be added upstream and maintained updated
 there, otherwise they are going the become quickly obsolete and of
 course stop to work

 cheers -- Giovanni --

I also got a similar suggestion from Paolo Cavallini of the LinkedIn QuantumGIS 
group that I should be doing the same. The fact of the matter is that I would 
really like to do just that.

How does one go about it? Is there any-one that can help me with this? As I am 
currently the only active developer and should actually be spending my time on 
research and teaching.
(I have not yet try to compile it under windows.)

Kind Regards
Magdaleen Ballot.

Thank you.
 
Q-Rap seems to work now with QGis version 2
 
And the web-site is updated ;-)

We are announcing the release of 2.0 shortly - first we have been pushing 
packages out to the repositories.

Someone would need to build it and check it in order to be able to tell you 
that.

Great that you plan to update your plugin to 2.0. I don't think the QRAP plugin 
is a good candidate for inclusion of the QGIS upstream project directly as its 
scope is limited to a very niche group of users. Also anything going into core 
should have a dedicated maintainer, so it should not be seen as a vehicle to 
offload the maintainance to other developers. It would be better to make an 
appeal here on the list (and perhaps the users list) for other developers to 
join you on the project.

In terms of hosting, we can certainly look at hosting QGIS in the github QGIS 
repository (or you could upload it to your own repo and make it public for 
others to fork).


Regards

Tim
