TButton Class Reference

A TButton object is a user interface object.

A TButton has a name and an associated action. When the button is clicked with the left mouse button, the corresponding action is executed.

A TButton can be created by direct invocation of the constructors or via the graphics editor.

The action can be set via TButton::SetMethod. The action can be any command. Examples of actions:

  • "34+78" When the button is clicked, the result of addition is printed.
  • ".x macro.C" . Clicking the button executes the macro macro.C The action can be modified at any time via TButton::SetMethod.

To modify the layout/size/contents of one or several buttons in a canvas, you must set the canvas editable via TCanvas::SetEditable. By default a TCanvas is editable. By default a TDialogCanvas is not editable. TButtons are in general placed in a TDialogCanvas.

A TButton being a TPad, one can draw graphics primitives in it when the TCanvas/TDialogCanvas is editable.

Example of a macro creating a dialog canvas with buttons:

void but() {
// example of a dialog canvas with a few buttons
TDialogCanvas *dialog = new TDialogCanvas("dialog","",200,300);
// Create first button. Clicking on this button will execute 34+56
TButton *but1 = new TButton("button1","34+56",.05,.8,.45,.88);
but1->Draw();
// Create second button. Clicking on this button will create a new canvas
TButton *but2 = new TButton("canvas","c2 = new TCanvas(\"c2\")",.55,.8,.95,.88);
but2->Draw();
// Create third button. Clicking on this button will invoke the browser
but3 = new TButton("Browser","br = new TBrowser(\"br\")",0.25,0.54,0.75,0.64);
but3->SetFillColor(42);
but3->Draw();
// Create last button with no name. Instead a graph is draw inside the button
// Clicking on this button will invoke the macro $ROOTSYS/tutorials/graphs/graph.C
button = new TButton("",".x tutorials/graphs/graph.C",0.15,0.15,0.85,0.38);
button->SetFillColor(42);
button->Draw();
button->SetEditable(kTRUE);
button->cd();
Double_t x[8] = {0.08,0.21,0.34,0.48,0.61,0.7,0.81,0.92};
Double_t y[8] = {0.2,0.65,0.4,0.34,0.24,0.43,0.75,0.52};
TGraph *graph = new TGraph(8,x,y);
graph->SetMarkerColor(4);
graph->SetMarkerStyle(21);
graph->Draw("lp");
dialog->cd();
}

Executing the macro above produces the following dialog canvas:

◆ Divide()

void TButton::Divide ( Int_t  nx = 1,
Int_t  ny = 1,
Float_t  xmargin = 0.01,
Float_t  ymargin = 0.01,
Int_t  color = 0 
)
inlinevirtual

Automatic pad generation by division.

  • The current canvas is divided in nx by ny equal divisions (pads).
  • xmargin is the space along x between pads in percent of canvas.
  • ymargin is the space along y between pads in percent of canvas.
  • color is the color of the new pads. If 0, color is the canvas color.

Pads are automatically named canvasname_n where n is the division number starting from top left pad.

Example if canvasname=c1 , nx=2, ny=3:

Once a pad is divided into sub-pads, one can set the current pad to a subpad with a given division number as illustrated above with TPad::cd(subpad_number).

For example, to set the current pad to c1_4, one can do:

c1->cd(4)

Note1: c1.cd() is equivalent to c1.cd(0) and sets the current pad to c1 itself.

Note2: after a statement like c1.cd(6), the global variable gPad points to the current pad. One can use gPad to set attributes of the current pad.

Note3: in case xmargin <=0 and ymargin <= 0, there is no space between pads. The current pad margins are recomputed to optimize the layout.
