Create an array to hold a bunch of numbers.

TGTable implements a table widget to display data in rows and columns. The data is supplied by a TVirtualTableInterface.

The table is a TGCanvas to make use of already available viewport functionality and drawing optimizations.

The top left cell in a table has coordinates (0,0)

A TObjArray is used internally to ensure little overhead and fast acces to cells.

If the data source has more rows than the default 50 rows of cells in memory, buttons at the bottom of the table can be used to load the next or previous chunk of data.

At the top of the table, a frame is visible that shows the coordinates of the top left cell currently in memmory in row,column. The amount of rows and columns is also shown in rows x columns. These values can be edited to move to a different area of the data source or to resize the table. Tab will switch between the enties, return will move to the currently entered range and resize the table if needed. Clicking the goto button has the same effect.

A TGTable is created by first creating an appropriate TVirtualTableInterface from the data that needs visualization and then creating the TGTable using this interface.

A simple macro to use a TGTable with a TGSimpleTableInterface:

{
   Int_t i = 0, j = 0;
   UInt_t nrows = 6, ncolumns = 5;
   Double_t** data = new Double_t*[nrows];
   for (i = 0; i < nrows; i++) {
      data[i] = new Double_t[ncolumns];
      for (j = 0; j < ncolumns; j++) {
         data[i][j] = 10 * i + j;
      }
   }
 
   // Create a main frame to contain the table
   TGMainFrame* mainframe = new TGMainFrame(0, 400, 200);
   mainframe->SetCleanup(kDeepCleanup) ;
 
   // Create an interface
   TGSimpleTableInterface *iface = new TGSimpleTableInterface(data, 6, 5);
 
   // Create the table
   TGTable *table = new TGTable(mainframe, 999, iface);
 
   // Add the table to the main frame
   mainframe->AddFrame(table, new TGLayoutHints(kLHintsExpandX | kLHintsExpandY));
 
   //Update data
   data[5][1] = 3.01;
   //update the table view
   table->Update();
 
   // Layout and map the main frame
   mainframe->SetWindowName("Tree Table Test") ;
   mainframe->MapSubwindows() ;
   mainframe->Layout();
   mainframe->Resize() ;
   mainframe->MapWindow() ;
 
   return mainframe;
}

It is also possible to visualise data from a tree. A simple macro showing the use of a TTreeTableInterface follows.

{
   // Open a root file.
   TFile *file = new TFile("$ROOTSYS/tutorials/hsimple.root");
   // Load a tree from the file
   TNtuple *ntuple = (TNtuple *)file->Get("ntuple");
 
   // Create an interface
   TTreeTableInterface *iface = new TTreeTableInterface(ntuple);
 
   // Create a main frame to contain the table
   TGMainFrame* mainframe = new TGMainFrame(0, 400, 200);
   mainframe->SetCleanup(kDeepCleanup) ;
 
   // Create the table
   TGTable *table = new TGTable(mainframe, 999, iface, 10, 6);
 
   // Add the table to the main frame
   mainframe->AddFrame(table, new TGLayoutHints(kLHintsExpandX | kLHintsExpandY));
 
   // Set a selection
   iface->SetSelection("px > 0.");
   // Add a column
   iface->AddColumn("(px+py)/(px-py)", 0);
   //update the table view
   table->Update();
 
   // Layout and map the main frame
   mainframe->SetWindowName("Tree Table Test") ;
   mainframe->MapSubwindows() ;
   mainframe->Layout();
   mainframe->Resize() ;
   mainframe->MapWindow() ;
 
   return mainframe;
}
