44 <center><h2>TGTable</h2></center>
45 <br><br>
46 TGTable implements a table widget to display data in rows and
47 columns. The data is supplied by a TVirtualTableInterface.
48 <br><br>
49 The table is a TGCanvas to make use of already available viewport
50 functionality and drawing optimizations.
51 <br><br>
52 The top left cell in a table has coordinates (0,0)
53 <br><br>
54 A TObjArray is used internally to ensure little overhead and fast
55 acces to cells.
56 <br><br>
57 If the data source has more rows than the default 50 rows of cells in
58 memory, buttons at the bottom of the table can be used to load the
59 next or previous chunk of data.
60 <br><br>
61 At the top of the table, a frame is visible that shows the coordinates
62 of the top left cell currently in memmory in row,column. The amount of
63 rows and columns is also shown in rows x columns. These values can be
64 edited to move to a different area of the data source or to resize the
65 table. Tab will switch between the enties, return will move to the
66 currently entered range and resize the table if needed. Clicking the
67 goto button has the same effect.
68 <br><br>
69 A TGTable is created by first creating an appropriate
70 TVirtualTableInterface from the data that needs visualization and
71 then creating the TGTable using this interface.
72 <br><br>
73 A simple macro to use a TGTable with a TGSimpleTableInterface:
74 End_Html
75 Begin_Macro(source, gui)
76 {
77  Int_t i = 0, j = 0;
78  UInt_t nrows = 6, ncolumns = 5;
79  Double_t** data = new Double_t*[nrows];
80  for (i = 0; i < nrows; i++) {
81  data[i] = new Double_t[ncolumns];
82  for (j = 0; j < ncolumns; j++) {
83  data[i][j] = 10 * i + j;
84  }
85  }
86 
87  // Create a main frame to contain the table
88  TGMainFrame* mainframe = new TGMainFrame(0, 400, 200);
89  mainframe->SetCleanup(kDeepCleanup) ;
90 
91  // Create an interface
92  TGSimpleTableInterface *iface = new TGSimpleTableInterface(data, 6, 5);
93 
94  // Create the table
95  TGTable *table = new TGTable(mainframe, 999, iface);
96 
97  // Add the table to the main frame
98  mainframe->AddFrame(table, new TGLayoutHints(kLHintsExpandX | kLHintsExpandY));
99 
100  //Update data
101  data[5][1] = 3.01;
102  //update the table view
103  table->Update();
104 
105  // Layout and map the main frame
106  mainframe->SetWindowName("Tree Table Test") ;
107  mainframe->MapSubwindows() ;
108  mainframe->Layout();
109  mainframe->Resize() ;
110  mainframe->MapWindow() ;
111 
112  return mainframe;
113 }
114 End_Macro
115 Begin_Html
116 
117 It is also possible to visualise data from a tree. A simple macro
118 showing the use of a TTreeTableInterface follows.
119 End_Html

126 
127  // Create an interface
128  TTreeTableInterface *iface = new TTreeTableInterface(ntuple);
129 
130  // Create a main frame to contain the table
131  TGMainFrame* mainframe = new TGMainFrame(0, 400, 200);
132  mainframe->SetCleanup(kDeepCleanup) ;
133 
134  // Create the table
135  TGTable *table = new TGTable(mainframe, 999, iface, 10, 6);
136 
137  // Add the table to the main frame
138  mainframe->AddFrame(table, new TGLayoutHints(kLHintsExpandX | kLHintsExpandY));
139 
140  // Set a selection
141  iface->SetSelection("px > 0.");
142  // Add a column
143  iface->AddColumn("(px+py)/(px-py)", 0);
144  //update the table view
145  table->Update();
146 
147  // Layout and map the main frame
