General Development

Hello All

I compiled hdbextractor, hdbextractor-qt, mathgl-2x, qdddplot, qgraphicsplot and Qhdbextractor successfully.
While running ./bin/qhdbextractor, following errors are coming:

HistoricalViewWidget::HistoricalViewWidgetcount() 0
TreeWidgetAxes CONSTRUCTOR
QLayout: Attempting to add QLayout “” to ExtScalePlotSceneWidget “”, which already has a layout
QLayout: Attempting to add QLayout “” to ExtScalePlotSceneWidget “”, which already has a layout

  • error: ExternalScaleWidget::setTickStepLen(): tickStepLen <=0 unsupported!
  • error: SettingsLoader::loadConfiguration: object name is empty
  • error: SettingsLoader::loadConfiguration: cannot load properties for obj. “”, class “PlotSceneWidget”
    adding “” class “WaitWidget” to index 0
    adding “” class “Plot2DWidget” to index 1
    adding “” class “QdddPlotWidget” to index 2

Any Suggestions ??

Thanks and Regards

Hi,

I guess you will have to wait for an answer from Giacomo Strangolino from Elettra, who is the hdb++ extractor gui expert.
He might be on vacation now.
At the ESRF, we are using jhdbviewer to visualize data stored in HDB++ and we don’t have much experience with Qt GUIs so I’m afraid we can’t help you on this one.

Cheers,
Reynald

Hello.
Apart from the errors, does the application work?
Are you able to fetch data from the database and display it?

Giacomo.

Hello Giacomo

I am not able to start the application itself.
While starting the applications itself by using $./qhdbextractor, the above errors come and it gets closed.

Thanks and Regards

Hello, does it say something else before closing?
Which version of QGraphicsPlot/TGraphicsPlot are you using? Did you check out the main trunk version?

Giacomo

Could you please throw away qgraphicsplot and rebuild it fetching it now from

svn checkout svn://svn.code.sf.net/p/tango-cs/code/gui/qgraphicsplot qgraphicsplot

and then do the same for TGraphicsPlot also:

svn checkout svn://svn.code.sf.net/p/tango-cs/code/gui/tgraphicsplot tgraphicsplot

and let me know.

Hello Giacomo

I have taken the code of qgraphicsplot from svn itself.
I have not build the tgraphics plot.

I have attached the image file of how the error comes.

I am building with qmake-qt4.

Ok, you need to edit a configuration file, as the dialog window says.
Inside the main distribution folder, you should find two examples, dbconfig and db++config files.
They are provided as examples to use for old hdb or new hdb++.

Have a look, edit them putting the correct information about database host name and user and password and try again.

Giacomo.

Hello Giacomo

The correct options have been provided in configuration files.
Database host, database user name , db name, db password all are correct.

Thanks and Regards

But as I can see from your screenshot, you didn’t provide the name of the configuration file on the command line.

Hello Giacomo

Yep i used the file db++config.dat with command line, THE GUI opened.
I have attached the open GUI.

I will check whether am able to fetch the data and retrieve from it and get back to you.

Also can I get some user manual for the using the GUI.

Fine! There are no manuals, in the hope that the UI is easy to use. If you got any question, write me.
There are API manuals if needed. They are installed together with the libraries installation.
