17 // ROOT EVENT RECORDING SYSTEM //
18 // ================================================================== //
19 // //
20 // TRecorder class provides interface for recording and replaying //
21 // events in ROOT. //
22 // Recorded events are: //
23 // - Commands typed by user in commandline ('new TCanvas') //
24 // - GUI events (mouse movement, button clicks, ...) //
25 // //
26 // All the recorded events from one session are stored in one TFile //
27 // and can be replayed again anytime. //
28 // //
29 // Recording //
30 // ================================================================== //
31 // //
32 // 1] To start recording //
33 // //
34 // TRecorder r(const char *filename, "NEW") //
35 // TRecorder r(const char *filename, "RECREATE") //
36 // //
37 // or: //
38 // //
39 // TRecorder *recorder = new TRecorder; //
40 // recorder->Start(const char *filename, ...) //
41 // //
42 // -filename Name of ROOT file in which to save //
43 // recorded events. //
44 // //
45 // 2] To stop recording //
46 // //
47 // recorder->Stop() //
48 // //
49 // //
50 // IMPORTANT: //
51 // State capturing is part of recording. It means that if you want to //
52 // record events for some object (window), creation of this object //
53 // must be also recorded. //
54 // //
55 // Example: //
56 // -------- //
57 // t = new TRecorder(); // Create a new recorder //
58 // t->Start("logfile.root"); // ! Start recording first //
59 // //
60 // c = new TCanvas(); // ! Then, create an object //
61 // c->Dump(); // Work with that object //
62 // //
63 // t->Stop(); // Stop recording //
64 // //
65 // It is strongly recommended to start recording with empty ROOT //
66 // environment, at least with no previously created ROOT GUI. //
67 // This ensures that only events for well known windows are stored. //
68 // Events for windows, which were not created during recording, //
69 // cannot be replayed. //
70 // //
71 // Replaying //
72 // =================================================================== //
73 // //
74 // 1] To start replaying //
75 // //
76 // TRecorder r(const char *filename) //
77 // TRecorder r(const char *filename, "READ") //
78 // //
79 // or: //
80 // //
81 // TRecorder *recorder = new TRecorder; //
82 // recorder->Replay(const char *filename, //
83 // Bool_t showMouseCursor = kTRUE); //
84 // //
85 // -filename A name of file with recorded events //
86 // previously created with TRecorder::Start //
87 // //
88 // -showMouseCursor If kTRUE, mouse cursor is replayed as well. //
89 // In that case it is not recommended to use mouse //
90 // during replaying. //
91 // //
92 // In general, it is not recommended to use mouse to change positions //
93 // and states of ROOT windows during replaying. //
94 // //
95 // IMPORTANT: //
96 // The state of ROOT environment before replaying of some events //
97 // must be exactly the same as before recording them. //
98 // Therefore it is strongly recommended to start both recording //
99 // and replaying with empty ROOT environment. //
100 // //
101 // 2] To pause replaying //
102 // //
103 // recorder->Pause() //
104 // //
105 // Replaying is stopped until recorder->Resume() is called. //
106 // //
107 // //
108 // 3] To resume paused replaying //
109 // //
110 // recorder->Resume() //
111 // //
112 // Resumes previously stopped replaying. //
113 // //
114 // //
115 // 4] To stop replaying before its end //
116 // //
117 // recorder->Stop() //
118 // //

381 // //
382 // Class provides direct recorder/replayer interface for a user. //
383 // See 'ROOT EVENT RECORDING SYSTEM' for more information about usage. //
384 // //
385 // Implementation uses C++ design pattern State. Functionality of //
386 // recorder is divided into 4 classes according to the current //
387 // state of recorder. //
388 // //
389 // Internally, there is a pointer to TRecorderState object. //
390 // This object changes whenever state of recorder is changed. //
391 // States of recorder are the following: //
392 // //
393 // - INACTIVE Implemented in TRecorderInactive class. //
394 // Default state after TRecorder object is created. //
395 // //
396 // - RECORDING Implemented in TRecorderRecording class. //
397 // //
398 // - REPLAYING Implemented in TRecorderReplaying class. //
399 // //
400 // - PAUSED Implemented in TRecorderPause class. //
401 // Pause of replaying. //
402 // //
403 // Every command for TRecorder is just passed //
404 // to TRecordeState object. //
405 // Depending on the current state of recorder, this command is passed //
406 // to some of the above mentioned classes and if valid, handled there. //
407 // //
408 // [TRecorder.JPG] //
409 // //
410 // Switching between states is not possible from outside. States are //
411 // switched directly by state objects via: //
412 // //
413 // ChangeState(TRecorderState* newstate, Bool_t deletePreviousState); //
414 // //
415 // When recorder is switched to a new state, the old state object is //
416 // typically deleted. The only exception is switching from REPLAYING //
417 // state to PAUSED state. The previous state (REPLAYING) is not //
418 // deleted in order to be used again after TRecorder::Resume call. //

427 // REPLAYING -> INACTIVE via TRecorder::ReplayStop (Stops replaying) //
