35 \ingroup guiwidgets
36
37Create an array to hold a bunch of numbers
38
39TGTable implements a table widget to display data in rows and
40columns. The data is supplied by a TVirtualTableInterface.
41
42The table is a TGCanvas to make use of already available viewport
43functionality and drawing optimizations.
44
45The top left cell in a table has coordinates (0,0)
46
47A TObjArray is used internally to ensure little overhead and fast
48acces to cells.
49
50If the data source has more rows than the default 50 rows of cells in
51memory, buttons at the bottom of the table can be used to load the
52next or previous chunk of data.
53
54At the top of the table, a frame is visible that shows the coordinates
55of the top left cell currently in memmory in row,column. The amount of
56rows and columns is also shown in rows x columns. These values can be
57edited to move to a different area of the data source or to resize the
58table. Tab will switch between the enties, return will move to the
59currently entered range and resize the table if needed. Clicking the
60goto button has the same effect.
61
62A TGTable is created by first creating an appropriate
63TVirtualTableInterface from the data that needs visualization and
64then creating the TGTable using this interface.
65
66A simple macro to use a TGTable with a TGSimpleTableInterface:
67
68~~~
69{
70 Int_t i = 0, j = 0;
71 UInt_t nrows = 6, ncolumns = 5;
72 Double_t** data = new Double_t*[nrows];
73 for (i = 0; i < nrows; i++) {
74 data[i] = new Double_t[ncolumns];
75 for (j = 0; j < ncolumns; j++) {
76 data[i][j] = 10 * i + j;
77 }
78 }
79
80 // Create a main frame to contain the table
81 TGMainFrame* mainframe = new TGMainFrame(0, 400, 200);
82 mainframe->SetCleanup(kDeepCleanup) ;
83
84 // Create an interface
85 TGSimpleTableInterface *iface = new TGSimpleTableInterface(data, 6, 5);
86
87 // Create the table
88 TGTable *table = new TGTable(mainframe, 999, iface);
89
90 // Add the table to the main frame
91 mainframe->AddFrame(table, new TGLayoutHints(kLHintsExpandX | kLHintsExpandY));
92
93 //Update data
94 data[5][1] = 3.01;
95 //update the table view
96 table->Update();
97
98 // Layout and map the main frame
99 mainframe->SetWindowName("Tree Table Test") ;
100 mainframe->MapSubwindows() ;
101 mainframe->Layout();
102 mainframe->Resize() ;
103 mainframe->MapWindow() ;
104
105 return mainframe;
106}
107~~~
108
109It is also possible to visualise data from a tree. A simple macro
110showing the use of a TTreeTableInterface follows.
111
112~~~
113{
114 // Open a root file.
115 TFile *file = new TFile("$ROOTSYS/tutorials/hsimple.root");
116 // Load a tree from the file
117 TNtuple *ntuple = (TNtuple *)file->Get("ntuple");
118
119 // Create an interface
120 TTreeTableInterface *iface = new TTreeTableInterface(ntuple);
121
122 // Create a main frame to contain the table
123 TGMainFrame* mainframe = new TGMainFrame(0, 400, 200);
124 mainframe->SetCleanup(kDeepCleanup) ;
125
126 // Create the table
127 TGTable *table = new TGTable(mainframe, 999, iface, 10, 6);
128
129 // Add the table to the main frame
130 mainframe->AddFrame(table, new TGLayoutHints(kLHintsExpandX | kLHintsExpandY));
131
132 // Set a selection
133 iface->SetSelection("px > 0.");
134 // Add a column
135 iface->AddColumn("(px+py)/(px-py)", 0);
136 //update the table view
137 table->Update();
138
139 // Layout and map the main frame
140 mainframe->SetWindowName("Tree Table Test") ;
141 mainframe->MapSubwindows() ;
142 mainframe->Layout();
143 mainframe->Resize() ;
144 mainframe->MapWindow() ;
145
146 return mainframe;
