Tour de table 10m

Tour de table ------------- Rene ==== tuning TFilePrefetch/TTreeFilePrefetch want to remove old cache before the release working with Leo for the next improvements working with Anna for the coming TEntryList Bertrand: ========= Finish TGTextEditor and PROOF Gui Anna ==== During last weeks I was working on the so called "virtual cuts", and on the changes to its design, following several long discussions. Right now, implementing a class TEntryList, which will be the base of the whole procedure to save the results of already computed selections, and looking into the needed changes in TTreeFormula. Ilka ==== - tested recently introduced changes in GUI classes by Valeriy Onuchin and the new TGTextEditor class by Bertrand; - implemented TGListTree::SavePrimitive, TGTextView::SavePrimitive - working on TF1/2/3Editor(s) design - investigated problem of object editor performance (caused by freely emitted signals by GUI elements and corresponding slots execution). Found a solution for all editors - will be in cvs today. - working with David on the ability for resizing the space taken by each header column in detailed view of TGListView Jani === New version of upload code for PROOF starting work on the packetizer Pere ==== ask status of I/O Multi-threading for CMS Philippe comments; The following should be thread safe-ish: TFile * f = TFile::Open(...); TTree * t = new TTree(...); t->SetDirectory(f); TH1F *h = new TH1F(....); h->SetDirectory(f); AnyType *obj = new .... f->Write(obj); David ====== Improving TGlistView class Olivier ======= Not done yet: * Investigate the possibility to translate the GS (PostScript) fonts file into TTF file to replace those in $ROOTSYS/fonts. * Implement the case with variable size bins in TH3::FitSlicesZ In progress: * Stress graphics: Add a new test in $ROOTSYS/tutorials to test the graphics issues. It will be called stressGraphics.cxx * Improve Polar graphs (we have now a first version which needs many improvements) - (Will be proposed to the summer student.) Done: * TGraph2D needs improvements: TGraph2D is meant to work on randomly distributed data sets. When the points are distributed on a regular grid,one may see peaks if the graph is drawn with "surf" options. The fix is almost done. Need more tests. Also the TRI option need improvements as pointed here: http://root.cern.ch/phpBB2/viewtopic.php?t=3489 Not previously foreseen but done: * TH3 - ProjectionZ and Project3D now take care of the alphanumeric labels. * TH2 - ProjectionX(Y): In case the X(Y) axis has alphanumeric labels, they are now copied in the 1D histogram being the result of the projection. Timur ===== * Next week I'm planning to add TGLSurfacePainter and, possibly, TGLBoxPainter. May be, I'll add new error option for TGLLegoPainter and error surfaces for TGLSurfacePainter. * TGLLegoPainter - "e" option added for cartesian - bar width/offset added for cartesian * TGLPlotPainter - normals for trapezoids in polar/cylindrical/spherical coordinates are better now, so lego is "smoother". * TGLPadHistpainter/TGLAxisPainter/TGLLegoPainter - new hist-painter infrastructure. - First version of TGLLegoPainter, the new class to support different types of legos: gl + lego(1)/lego2 + pol/cyl/sph gl + lego3 - TGLUtil : Small auxilary classes. - This lego painter is still experimantal and works only if it's enabled in system.rootrc. By default, TGLHistPainter is used now. To enable this new system the line: Plugin.TGLHistPainter: * TGLHistPainter RGL "TGLHistPainter(TH1*)" Must be replaced with Plugin.TGLHistPainter: * TGLPadHistPainter RGL "TGLPadHistPainter(TH1*)" in $ROOTSYS/etc/system.rootrc
