Function Documentation

void gui_ccu_display_status (  struct ccu_status_struct  status  )

display the current status of the CCU using GTK Returns: void The current status of the CCU is read using status=ccu_get_status() The elemnts in the gboccia main window and in the terminal window are updated according to status read

void gui_done_ccddatabasewindow (   )

parses the "ccd database" window Returns: void This function parses the "ccd database" window, the results are stored in gui_observername, gui_telescopename and gui_instrumentname, for later use in the fitsfile.

void gui_done_dapwindow (  void   )

parses the "data associated parameters" window Returns: void This function parses the "data associated parameters" window, the results are stored in gui_observername, gui_telescopename and gui_instrumentname, for later use in the fitsfile.

int gui_done_databasewinddow (  void   )

parses the "database" window and starts the download of the selected database into the CCU Returns: interger (0 means success, -1 means fail) This function parses the "database" window. The results are to ccu_channels (dual channel readout) and ccu_database_filename. The download of the selected database into the CCU is started.

void gui_done_multiplewindow (  void   )

parses the multiple exposure window Returns: void This function parses the multiple exposure window and starts a multiple exposure.

int gui_done_queuewinddow (  void   )

parses the "queue" window, loads and starts the selected queue in the CCU Returns: interger (0 means success, -1 means fail) This function parses "queue" window, it loads and starts the selected queue in the CCU.

gboolean gui_idle (  void   )

performs the changes of the GUIas requested by the threads Returns: void This function performs the changes of the GUIas requested by the threads , is stated every now and then by GTK using the gtk_add_idle mechanism

void gui_init_dapwinddow (  void   )

initializes the "data associated parameters" window Returns: void This function sets up the "data associated parameters" window, reading data form gui_observername, gui_telescopename and gui_instrumentname.

void gui_init_databasewinddow (  void   )

initializes the "database" window Returns: void This function displays the current ccu_database_filename and the flag dual channel readout (ccu_channels).

void gui_init_instctrlwinddow (  void   )

initializes the "instrument control" window Returns: void This function sets the value in the entry "Telescope Focus (desired)" to the value read from "Telescope Focus (actual)" entry in the "instrument control" window.

int gui_init_specialgaincombo (  void   )

initializes the "gain" combobox in the "special exposure" window Returns: void the gain combobox is filled with Gain numbers von 1 to 8.

int gui_init_specialsequencecombo (  void   )

initialize the "sequence" combobox in the "special exposure" window Returns: void the sequences are loaded from the ui_ccu_sequence_context array into the combo box.

void gui_push_item (  struct gui_update_struct  input  )

queues a gui change request. Returns: void This function queues a gui change request it is called by a thread who wants to change the gui.

void gui_queue_buttons (  struct gui_button_struct  input  )

queues a gui change request concerning buttons. Parameters: input  a gui_button_struct containing the button status requested Returns: void This function queues a gui change request concerning buttons it is called by a thread who wants to change the gui.

void gui_queue_normal (  void   )

queues a normal exposure Returns: void This function queues a normal exposure into the acquisition queue, it is used whenever the "Start Exposure" button in the gboccia main window is clicked

void gui_queue_objectname (  char *  input  )

queues a gui change request concerning the objectname entry. Parameters: input  a C string cotaining to be writen into the objectname entry. Returns: void This function queues a gui change request concerning the objectname entry it is called by a thread who wants to change the gui.

void gui_show_full (  void   )

starts the external fits viewer Returns: void the programm given by the inifile entry [extern:saods9] is started in the background. The current fitsfilename is passed to it as command line argument.

void gui_update_buttons (  struct gui_button_struct  input  )

sets the buttons in the gboccia main window to a state given by the parameter Parameters: input  a struct descibing the status of the buttons, to be set Returns: void This function sets the buttons in the gboccia main window to a state given by the parameter.

void init_drawarea (  void   )

sets up rgbbuffer Returns: void This function sets up GTK to display RGB data, and enebale GTK to redisplay rgbbuffer whenever nessary

int init_gaincombo (  void   )

initializes the "gain" combobox in the gboccia main window Returns: void the gain combobox is filled with Gain numbers von 1 to 8.

void init_gui (  void   )

initializes the graphical user interface Returns: void the buttons are set up, the gui_lastname variable is initialized. The font in the columned list in the CCU terminal window is set to "Monospace 10", the gain combox in the gboccia main window is initialized

void init_sequencecombo (  void   )

initialize the "sequence" combobox in the gboccia main window Returns: void the sequences are loaded from the ui_ccu_sequence_context array into the combo box the sequnce with number 0 is ommitted because it contains the dummy read sequence, which is not usefull to acquire frames. The sequence with number 14 is ommited because they contains the zero volt sequence, which is not usefull to acquire frames. The sequence with number 15 is ommited because it is probably not properly inmplementet in the CCU.

void on_darea_expose (  GtkWidget *  widget, GdkEventExpose *  event, gpointer  user_data )

GTK callback for rgbbuffer expose event. Parameters: widget  a pointer to the widget containing rgbbuffer event  the expose event Returns: void This function is called by GTK whenever it needs to redisplay rgbbuffer

int parse_gui (  void   )

parses the gboccia main window Returns: interger (0 means ok, -1 means fail)
