_HADES_CLASS_DESCRIPTION

 HOnlineMonClientMain

 Main class of the HADES Online Monitoring Client.
 It contains a separat Thread in which the histograms are updated.
 The canvases are updated in the main thread, because the
 canvas-update is not threadsafe.

Function documentation

HOnlineMonClientMain(TString filename = "")

 filename is the name of the xml configuration file

void Init(Bool_t sendCmdOnly = kFALSE, TString host = "", Int_t port = 0, TString cmd = "")

 Initialize program.
 If there is a command, execute it and exit.
 Else start client program with graphical user interface

void* ThreadUpdateHists(void* arg)

void UpdateHists()

void CreateClientConfig(TString xmlfile)

 Parse configuration file

void CreateDetGui(HOnlineMonClientDet* detector)

 Create and show all windows from given detector

void DestroyDetGui(HOnlineMonClientDet* detector)

 Hide and destroy all windows from given detector

void DestroySingleWindow(HOnlineMonClientSimpleWin* window)

 Hide and destroy a single simple window

void DestroySingleWindow(HOnlineMonClientTabWin* window)

 Hide and destroy a single tab window

void HandleRefreshRateChange()

 GUI Event Handler to handle change of refresh rate

void HandleAutoSaveRateChange()

 GUI Event Handler to handle change of refresh rate

void HandleSendStopServer()

void HandleSendResetHists()

void HandleConnectionError()

void HandleTryClose()

void HandleSnapshotSave()

 GUI Event Handler to handle snapshot button click
 Save all active canvases in a ps file in the same folder as the program.
 The filename contains a timestamp

void HandleSnapshotSaveOnline()

 GUI Event Handler to handle snapshot button click
 Save all active canvases in png file in the online snapshot path.

void HandleMainWindowClose()

 GUI Event Handler to handle close-event of the main window

~HOnlineMonClientMain()

void HandleControlbuttonClick(char* detectorname)

void SetUpdateInterval(Int_t msec)

Bool_t Connect(TString host, Int_t port)

Bool_t ReConnect(TString host, Int_t port)

Bool_t UpdateHist(HOnlineMonClientHist* hist)

 update a single histogram and draw it on the current canvas.
 A timestamp is added to the histogram title

TString SendCmdToServer(TString cmd)

TList* GetListOfHistograms()

HOnlineMonHistAddon* GetHist(TString histoname)

void AddHist(HOnlineMonClientCanvas* canvas, HOnlineMonClientHist* hist)

 lists listHists / listPads.
 All histograms and canvases/pads in these lists are updated
 by the update-function

void RemoveHist(HOnlineMonClientCanvas* canvas, HOnlineMonClientHist* hist)

 Remove canvas and hist from the global list. Then, the hist and the canvas
 are no longer updated

void SetServerport(Int_t port)

Int_t GetServerport()

Int_t GetUpdateInterval()

{ return UpdateInterval;}

void SetAutoSaveInterval(Int_t minute)

{AutoSaveInterval = minute;}

void SetAutoSaveIntervalOnline(Int_t minute)

{AutoSaveIntervalOnline = minute;}

TThread* getMainThread()

{ return mainThread; }

Int_t IsMasterClient()

{ return isMasterClient <= 0 ? kFALSE : kTRUE ;}

Int_t GetMasterClient()

{ return isMasterClient ;}

void SetIsMasterClient(Bool_t master)

{ isMasterClient = master;}

Int_t GetReconnect()

{ return doReconnect;}

void SetReconnect(Int_t recon)

{ doReconnect = recon;}
