◆ Connect() [1/3]

Bool_t TQObject::Connect	(	const char *	class_name,
		const char *	signal,
		const char *	cl,
		void *	receiver,
		const char *	slot )

staticinherited

This method allows to make a connection from any object of the same class to a single slot.

Signal and slot string must have a form: "Draw(char*, Option_t* ,Int_t)" All blanks and "const" words will be removed,

cl != 0 - class name, it can be class with or without dictionary, e.g interpreted class. Example:

TGButton *myButton;
TH2F     *myHist;
 
TQObject::Connect("TGButton", "Clicked()",
                  "TH2F", myHist, "Draw(Option_t*)");

cl == 0 - corresponds to function (interpereted or global) the name of the function is defined by the slot string, parameter receiver should be 0. Example:

TGButton *myButton;
TH2F     *myHist;
 
TQObject::Connect("TGButton", "Clicked()",
                  0, 0, "hsimple()");

TQObject::Connect(myButton,"Clicked()",
                  "TH2F", myHist,"Draw(Option_t*)");

cl == 0 - corresponds to function (interpereted or global) the name of the function is defined by the slot string, parameter receiver should be 0. Example:

TGButton *myButton;
TH2F     *myHist;
 
TQObject::Connect(myButton,"Clicked()",

◆ Disconnect() [2/3]

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

inherited

Disconnects signal of this object from slot of receiver.

Equivalent to Disconnect(this, signal, receiver, slot)

Definition at line 1023 of file TQObject.cxx.

◆ 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);

TQObject::Disconnect
Bool_t Disconnect(const char *signal=nullptr, void *receiver=nullptr, const char *slot=nullptr)
Disconnects signal of this object from slot of receiver.
Definition TQObject.cxx:1023
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.

◆ Disconnected()

virtual void TQObject::Disconnected ( const char * )

inlinevirtualinherited

Definition at line 195 of file TQObject.h.

◆ Emit() [1/2]

void TQObject::Emit ( const char * signal )

inlineinherited

Activate signal without args.

Example: theButton->Emit("Clicked()");

Definition at line 174 of file TQObject.h.

◆ Emit() [2/2]

template<typename T>

void TQObject::Emit	(	const char *	signal,
		const T &	arg )

inlineinherited

Activate signal with single parameter.

Example:

theButton->Emit("Progress(Long64_t)",processed)

If we call Emit with an array of the parameters, they should be converted to Longptr_t type. Example:

TQObject *processor; // data processor
TH1F     *hist;      // filled with processor results
 
processor->Connect("Evaluated(Float_t,Float_t)",
                   "TH1F",hist,"Fill12(Axis_t,Axis_t)");
 
Longptr_t args[2];
args[0] = (Longptr_t)processor->GetValue(1);
args[1] = (Longptr_t)processor->GetValue(2);
 
processor->Emit("Evaluated(Float_t,Float_t)",args);
