TSlider Class Reference

A specialized TPad including a TSliderBox object.

The TSliderBox can be moved in the pad.

Slider drawing options include the possibility to change the slider starting and ending positions or only one of them.

The current slider position can be retrieved via the functions TSlider::GetMinimum and TSlider::GetMaximum These two functions return numbers in the range [0,1].

If a method has been set (via TSlider::SetMethod), the expression is executed via the interpreter when the button 1 is released.

if no method has been set, and an object is referenced (TSlider::SetObject has been called), while the slider is being moved/resized, the object ExecuteEvent function is called.

Example 1 using TSlider::SetMethod

macro xyslider.C

void xyslider()
{
   // Example of macro featuring two sliders
   TFile *f = new TFile("hsimple.root");
   TH2F *hpxpy = (TH2F*)f->Get("hpxpy");
   TCanvas *c1 = new TCanvas("c1");
   TPad *pad = new TPad("pad","Color plot pad",0.1,0.1,0.98,0.98);
   pad->Draw();
   pad->cd();
   hpxpy->Draw("COLZ");
   c1->cd();
 
   // Create two sliders in main canvas. When button1 will be released
   // the macro action.C will be called.
   TSlider *xslider = new TSlider("xslider","x",0.1,0.02,0.98,0.08);
   xslider->SetMethod(".x action.C");
   TSlider *yslider = new TSlider("yslider","y",0.02,0.1,0.06,0.98);
   yslider->SetMethod(".x action.C");
}

macro action.C

void action()
{
   Int_t nx = hpxpy->GetXaxis()->GetNbins();
   Int_t ny = hpxpy->GetYaxis()->GetNbins();
   Int_t binxmin = nx*xslider->GetMinimum();
   Int_t binxmax = nx*xslider->GetMaximum();
   hpxpy->GetXaxis()->SetRange(binxmin,binxmax);
   Int_t binymin = ny*yslider->GetMinimum();
   Int_t binymax = ny*yslider->GetMaximum();
   hpxpy->GetYaxis()->SetRange(binymin,binymax);
   pad->cd();
   hpxpy->Draw("COLZ");
   c1->Update();
}

The canvas and the sliders created in the above macro are shown in the picture below.

Example 2 using TSlider::SetObject macro xyslider.C

Same example as above. Instead of TSlider::SetMethod:

Myclass *obj = new Myclass(); // Myclass derived from TObject
xslider->SetObject(obj);
yslider->SetObject(obj);

When the slider will be changed, MyClass::ExecuteEvent will be called with px=0 and py = 0

Enumerator

kOnlyPrepStep

Used to request that the class specific implementation of TObject::Write just prepare the objects to be ready to be written but do not actually write them into the TBuffer. This is just for example by TBufferMerger to request that the TTree inside the file calls TTree::FlushBaskets (outside of the merging lock) and TBufferMerger will later ask for the write (inside the merging lock). To take advantage of this feature the class needs to overload TObject::Write and use this enum value accordingly. (See TTree::Write and TObject::Write) Do not use, this feature will be migrate to the Merge function (See TClass and TTree::Merge)

AbstractMethod()

void TObject::AbstractMethod ( const char * method ) const

inherited

Call this function within a function that you don't want to define as purely virtual, in order not to force all users deriving from that class to implement that maybe (on their side) unused function; but at the same time, emit a run-time warning if they try to call it, telling that it is not implemented in the derived class: action must thus be taken on the user side to override it.

In other word, this method acts as a "runtime purely virtual" warning instead of a "compiler purely virtual" error.

Warning

This interface is a legacy function that is no longer recommended to be used by new development code.

Note

The name "AbstractMethod" does not imply that it's an abstract method in the strict C++ sense.

Add()

void TPad::Add ( TObject * obj, Option_t * opt = "", Bool_t modified = kTRUE )

overridevirtualinherited

Add an object to list of primitives with specified draw option When.

modified set to kTRUE (default) pad will be marked as modified

Let avoid usage of gPad when drawing object(s) in canvas or in subpads.

auto c1 = new TCanvas("c1","Canvas with subpoads", 600, 600);
c1->Divide(2,2);
 
for (Int_t n = 1; n <= 4; ++n) {
   auto h1 = new TH1I(TString::Format("hist_%d",n), "Random hist", 100, -5, 5);
   h1->FillRandom("gaus", 2000 + n*1000);
   c1->GetPad(n)->Add(h1);
}

Implements TVirtualPad.

Definition at line 419 of file TPad.cxx.

AddExec()

void TPad::AddExec ( const char * name, const char * command )

overridevirtualinherited

Add a new TExec object to the list of Execs.

When an event occurs in the pad (mouse click, etc) the list of C++ commands in the list of Execs are executed via TPad::AutoExec.

When a pad event occurs (mouse move, click, etc) all the commands contained in the fExecs list are executed in the order found in the list.

This facility is activated by default. It can be deactivated by using the canvas "Option" menu.

The following examples of TExec commands are provided in the tutorials: macros exec1.C and exec2.C.

Example1 of use of exec1.C

Root > TFile f("hsimple.root")
Root > hpx.Draw()
Root > c1.AddExec("ex1",".x exec1.C")

At this point you can use the mouse to click on the contour of the histogram hpx. When the mouse is clicked, the bin number and its contents are printed.

Example2 of use of exec1.C

Root > TFile f("hsimple.root")
Root > hpxpy.Draw()
Root > c1.AddExec("ex2",".x exec2.C")

When moving the mouse in the canvas, a second canvas shows the projection along X of the bin corresponding to the Y position of the mouse. The resulting histogram is fitted with a gaussian. A "dynamic" line shows the current bin position in Y. This more elaborated example can be used as a starting point to develop more powerful interactive applications exploiting the C++ interpreter as a development engine.

overridevirtualinherited

Build a legend from the graphical objects in the pad.

A simple method to build automatically a TLegend from the primitives in a TPad.

Only those deriving from TAttLine, TAttMarker and TAttFill are added, excluding TPave and TFrame derived classes.

Returns

The built TLegend

Parameters

[in]	x1,y1,x2,y2	The TLegend coordinates
[in]	title	The legend title. By default it is " "
[in]	option	The TLegend option

The caller program owns the returned TLegend.

If the pad contains some TMultiGraph or THStack the individual graphs or histograms in them are added to the TLegend.

Automatic placement of the legend

If x1 is equal to x2 and y1 is equal to y2 the legend will be automatically placed to avoid overlapping with the existing primitives already displayed. x1 is considered as the width of the legend and y1 the height. By default the legend is automatically placed with width = x1= x2 = 0.3 and height = y1= y2 = 0.21.

cd()

TVirtualPad * TPad::cd ( Int_t subpadnumber = 0 )

overridevirtualinherited

Set Current pad.

When a canvas/pad is divided via TPad::Divide, one can directly set the current path to one of the subdivisions. See TPad::Divide for the convention to number sub-pads.

Returns the new current pad, or 0 in case of failure.

For example:

c1.Divide(2,3); // create 6 pads (2 divisions along x, 3 along y).

To set the current pad to the bottom right pad, do

c1.cd(6);

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: One can get a pointer to one of the sub-pads of pad with: TPad subpad = (TPad)pad->GetPad(subpadnumber);

virtualinherited

Clip polygon using the Sutherland-Hodgman algorithm.

Parameters

[in]	n	Number of points in the polygon to be clipped
[in]	x,y	Polygon x[n], y[n] do be clipped vertices
[in]	xclipl,yclipb,xclipr,yclipt	Clipping boundary
[out]	nn	Number of points in xc and yc
[out]	xc,yc	Clipped polygon vertices. The Int_t returned by this function is the number of points in the clipped polygon. These vectors must be allocated by the calling function. A size of 2*n for each is enough.

Sutherland and Hodgman's polygon-clipping algorithm uses a divide-and-conquer strategy: It solves a series of simple and identical problems that, when combined, solve the overall problem. The simple problem is to clip a polygon against a single infinite clip edge. Four clip edges, each defining one boundary of the clip rectangle, successively clip a polygon against a clip rectangle.

Steps of Sutherland-Hodgman's polygon-clipping algorithm:

• Polygons can be clipped against each edge of the window one at a time. Windows/edge intersections, if any, are easy to find since the X or Y coordinates are already known.
• Vertices which are kept after clipping against one window edge are saved for clipping against the remaining edges.
• Note that the number of vertices usually changes and will often increases.

The clip boundary determines a visible and invisible region. The edges from vertex i to vertex i+1 can be one of four types:

• Case 1 : Wholly inside visible region - save endpoint
• Case 2 : Exit visible region - save the intersection
• Case 3 : Wholly outside visible region - save nothing
• Case 4 : Enter visible region - save intersection and endpoint

Disconnect() [3/3]

Bool_t TQObject::Disconnect ( TQObject * sender, const char * signal = nullptr, void * receiver = nullptr, const char * slot = nullptr )

staticinherited

Disconnects signal in object sender from slot_method in object receiver.

For objects derived from TQObject signal-slot connection is removed when either of the objects involved are destroyed.

Disconnect() is typically used in three ways, as the following examples shows:

• Disconnect everything connected to an object's signals:

  Disconnect(myObject);

• Disconnect everything connected to a signal:

  Disconnect(myObject, "mySignal()");

• Disconnect a specific receiver:

  Disconnect(myObject, 0, myReceiver, 0);

0 may be used as a wildcard in three of the four arguments, meaning "any signal", "any receiving object" or "any slot in the receiving object", respectively.

The sender has no default and may never be 0 (you cannot disconnect signals from more than one object).

If signal is 0, it disconnects receiver and slot_method from any signal. If not, only the specified signal is disconnected.

If receiver is 0, it disconnects anything connected to signal. If not, slots in objects other than receiver are not disconnected

If slot_method is 0, it disconnects anything that is connected to receiver. If not, only slots named slot_method will be disconnected, and all other slots are left alone. The slot_method must be 0 if receiver is left out, so you cannot disconnect a specifically-named slot on all objects.

Divide()

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

overridevirtualinherited

Automatic pad generation by division.

• The current canvas is divided in nx by ny equal divisions (pads).
• xmargin defines the horizontal spacing around each pad as a percentage of the canvas width. Therefore, the distance between two adjacent pads along the x-axis is equal to twice the xmargin value.
• ymargin defines the vertical spacing around each pad as a percentage of the canvas height. Therefore, the distance between two adjacent pads along the y-axis is equal to twice the ymargin value.
• 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 or ymargin < 0, there is no space between pads. The current pad margins are recomputed to optimize the layout in order to have similar frames' areas. See the following example:

void divpad(Int_t nx=3, Int_t ny=2) {
   gStyle->SetOptStat(0);
   auto C = new TCanvas();
   C->SetMargin(0.3, 0.3, 0.3, 0.3);
   C->Divide(nx,ny,-1);
   Int_t number = 0;
   auto h = new TH1F("","",100,-3.3,3.3);
   h->GetXaxis()->SetLabelFont(43);
   h->GetXaxis()->SetLabelSize(12);
   h->GetYaxis()->SetLabelFont(43);
   h->GetYaxis()->SetLabelSize(12);
   h->GetYaxis()->SetNdivisions(505);
   h->SetMaximum(30*nx*ny);
   h->SetFillColor(42);
   for (Int_t i=0;i<nx*ny;i++) {
      number++;
      C->cd(number);
      h->FillRandom("gaus",1000);
      h->DrawCopy();

Return true is the type of this object is known to have an inconsistent setup for Hash and RecursiveRemove (i.e.

missing call to RecursiveRemove in destructor).

Note: Since the consistency is only tested for during inserts, this routine will return true for object that have never been inserted whether or not they have a consistent setup. This has no negative side-effect as searching for the object with the right or wrong Hash will always yield a not-found answer (Since anyway no hash can be guaranteed unique, there is always a check)

Write() [2/2]

Int_t TObject::Write ( const char * name = nullptr, Int_t option = 0, Int_t bufsize = 0 ) const

virtualinherited

Write this object to the current directory.

The data structure corresponding to this object is serialized. The corresponding buffer is written to the current directory with an associated key with name "name".

Writing an object to a file involves the following steps:

• Creation of a support TKey object in the current directory. The TKey object creates a TBuffer object.
• The TBuffer object is filled via the class::Streamer function.
• If the file is compressed (default) a second buffer is created to hold the compressed buffer.
• Reservation of the corresponding space in the file by looking in the TFree list of free blocks of the file.
• The buffer is written to the file.

Bufsize can be given to force a given buffer size to write this object. By default, the buffersize will be taken from the average buffer size of all objects written to the current file so far.

If a name is specified, it will be the name of the key. If name is not given, the name of the key will be the name as returned by GetName().

The option can be a combination of: kSingleKey, kOverwrite or kWriteDelete Using the kOverwrite option a previous key with the same name is overwritten. The previous key is deleted before writing the new object. Using the kWriteDelete option a previous key with the same name is deleted only after the new object has been written. This option is safer than kOverwrite but it is slower. NOTE: Neither kOverwrite nor kWriteDelete reduces the size of a TFile– the space is simply freed up to be overwritten; in the case of a TTree, it is more complicated. If one opens a TTree, appends some entries, then writes it out, the behaviour is effectively the same. If, however, one creates a new TTree and writes it out in this way, only the metadata is replaced, effectively making the old data invisible without deleting it. TTree::Delete() can be used to mark all disk space occupied by a TTree as free before overwriting its metadata this way. The kSingleKey option is only used by TCollection::Write() to write a container with a single key instead of each object in the container with its own key.

An object is read from the file into memory via TKey::Read() or via TObject::Read().

The function returns the total number of bytes written to the file. It returns 0 if the object cannot be written.
