TQCommand Class Reference

The Command design pattern is based on the idea, that all editing in an application is done by creating instances of command objects.

Command objects apply changes to the edited object and then are stored on a command stack. Furthermore, each command knows how to undo its changes to bring the edited object back to its previous state. As long as the application only uses command objects to change the state of the edited object, it is possible to undo a sequence of commands by traversing the command stack downwards and calling the "undo" method of each command in turn. It is also possible to redo a sequence of commands by traversing the command stack upwards and calling the "redo" method of each command.

Examples:

1. Create a new command

   TQCommand *com = new TQCommand("TH1", hpx, "SetFillColor(Color_t)"
                                "SetFillColor(Color_t)");

   • 1st parameter - the name of class
   • 2nd parameter - object
   • 3rd parameter - the name of do/redo method
   • 4th parameter - the name of undo method Since redo,undo methods are the same, undo name can be omitted, e.g.

     TQCommand *com = new TQCommand("TH1", hpx, "SetFillColor(Color_t)");

     For objects derived from TObject class name can be omitted, e.g.

     TQCommand *com = new TQCommand(hpx, "SetFillColor(Color_t)");

2. Setting undo, redo parameters.

   Color_t old_color = hpx->GetFillColor();
   Color_t new_color = 4;  // blue color
    
   com->SetRedoArgs(1, new_color);
   com->SetUndoArgs(1, old_color);

   1st argument - the number of undo, redo parameters the other arguments - undo, redo values Since the number of undo,redo parameters is the same one can use

   com->SetArgs(1, new_color, old_color);

3. Undo, redo method execution

   com->Redo(); // execute redo method
   com->Undo(); // execute undo method

4. Merged commands It possible to group several commands together so an end user can undo and redo them with one command.

   TQCommand *update = new TQCommand(gPad, "Modified()");
   com->Add(update);

5. Macro commands "Merging" allows to create macro commands, e.g.

   TQCommand *macro = new TQCommand("my macro");
   macro->Add(com1);
   macro->Add(com2);
   ...

   During Redo operation commands composing macro command are executed sequentially in direct order (first in first out). During Undo, they are executed in reverse order (last in first out).
6. Undo manager. TQUndoManager is recorder of undo and redo operations. This is command history list which can be traversed backwards and upwards performing undo and redo operations. To register command TQUndoManager::Add(TObject*) method is used.

   TQUndoManager *history = new TQUndoManager();
   history->Add(com);

   TQUndoManager::Add automatically invokes execution of command's Redo method.

Use TQUndoManager::Undo to undo commands in history list. Redo is Undo for undo action. Use TQUndoManager::Redo method for that

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)

TQCommand() [1/3]

TQCommand::TQCommand	(	const char *	clname = nullptr,
		void *	obj = nullptr,
		const char *	redo = nullptr,
		const char *	undo = nullptr )

Constructor.

Input parameters:

1. clname - class name.
2. obj - an object
3. redo - method or function to do/redo operation
4. undo - method or function to undo operation

Comments:

• if either clname or obj is NULL that means that redo/undo is function
• to specify default arguments for redo/undo method/function '=' must precede to argument value.

Example:

TQCommand("TPad", gPad, "SetEditable(=kTRUE)", "SetEditable(=kFALSE)");

undo method can be same as redo one. In that case undo parameter can be omitted.

Example:

TQCommand("TPad", gPad, "SetFillStyle(Style_t)");

Member Function Documentation

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.

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.

Note: If this routine is overloaded in a derived class, this derived class should also add

ROOT::CallRecursiveRemoveIfNeeded(*this)

Otherwise, when RecursiveRemove is called (by ~TObject or example) for this type of object, the transversal of THashList and THashTable containers will will have to be done without call Hash (and hence be linear rather than logarithmic complexity). You will also see warnings like

Error in <ROOT::Internal::TCheckHashRecursiveRemoveConsistency::CheckRecursiveRemove>: The class SomeName overrides
TObject::Hash but does not call TROOT::RecursiveRemove in its destructor.

inlineinherited

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)

Merge method is analogous to logical join operation.

Note: Merge method invokes redo action.

Definition at line 327 of file TQCommand.cxx.

Merge() [3/3]

Long64_t TSeqCollection::Merge ( TCollection * list )

inherited

Merge this collection with all collections coming in the input list.

The input list must contain other collections of objects compatible with the ones in this collection and ordered in the same manner. For example, if this collection contains a TH1 object and a tree, all collections in the input list have to contain a histogram and a tree. In case the list contains collections, the objects in the input lists must also be collections with the same structure and number of objects. If some objects inside the collection are instances of a class that do not have a Merge function (like TObjString), rather than merging, a copy of each instance (via a call to Clone) is appended to the output.

Example

  this                          list
____________                  ---------------------|
| A (TH1F) |  __________      | L1 (TSeqCollection)|- [A1, B1(C1,D1,E1)]
| B (TList)|-| C (TTree)|     | L1 (TSeqCollection)|- [A2, B2(C2,D2,E2)]

Write all objects in this collection.

By default all objects in the collection are written individually (each object gets its own key). Note, this is recursive, i.e. objects in collections in the collection are also written individually. To write all objects using a single key specify a name and set option to TObject::kSingleKey (i.e. 1).

Reimplemented from TObject.

Reimplemented in TMap.
