;+ ;NAME: ; spd_ui_load_omni_import ; ;PURPOSE: ; This routine provides an example for loading data into the GUI from the load ; data panel. The purpose of this routine is to provide a wrapper around the actual ; load data procedure (which is mission specific). This routine handles all the ; 'administrative' work of validating times, checking if data exists, and adding the ; data to the GUI's loadedData object. The loadedData object loads and tracks ; all data that is available to the GUI. ; ;HISTORY: ; ;;$LastChangedBy: nikos $ ;$LastChangedDate: 2014-11-03 11:56:50 -0800 (Mon, 03 Nov 2014) $ ;$LastChangedRevision: 16127 $ ;$URL: svn+ssh://thmsvn@ambrosia.ssl.berkeley.edu/repos/spdsoft/trunk/projects/geom_indices/spd_ui_load_omni_import.pro $ ; ;-------------------------------------------------------------------------------- pro spd_ui_load_omni_import,$ loadStruc, $ loadedData,$ statusBar,$ historyWin,$ parent_widget_id,$ ;needed for appropriate layering and modality of popups replay=replay,$ overwrite_selections=overwrite_selections ;allows replay of user overwrite selections from spedas compile_opt hidden,idl2 ; initialize variables res=loadStruc.res datatypes=loadStruc.datatypes timerange=loadStruc.timerange loaded = 0 new_vars = '' overwrite_selection='' overwrite_count =0 if ~keyword_set(replay) then begin overwrite_selections = '' endif ; **** Specify the starting and ending time ranges for this mission ***** ; **** this should be modified for each new mission ***** omnimintime = '1970-01-01' omnimaxtime = '2050-12-31' ; in this example data is loaded into temporary tplot variables. the existing ; tplot names are determined before the load so that later in the procedure ; when the code is deleting the temporary tplot variables the previous ones will ; not get clobbered as well tn_before = [tnames('*',create_time=cn_before)] ; ***** This is the routine that loads the actual data ***** ; ***** This routine is provided by each mission ***** min1res=0 min5res=0 FOR i=0, n_elements(res)-1 DO BEGIN IF strpos('5min',res[i]) GT -1 THEN min5res=1 IF strpos('1min',res[i]) GT -1 THEN min1res=1 ENDFOR IF min5res EQ 1 THEN omni_hro_load, res5min=1, trange=timeRange IF min1res EQ 1 THEN omni_hro_load, trange=timeRange ; determine which tplot vars to delete and which ones are the new temporary vars spd_ui_cleanup_tplot, tn_before, create_time_before=cn_before, del_vars=to_delete,$ new_vars=new_vars if time_double(omnimaxtime) lt time_double(timerange[1]) || $ time_double(omnimintime) gt time_double(timerange[0]) then begin statusBar->update,'No OMNI Data Loaded, OMNI data is only available between ' + omnimintime + ' and ' + omnimaxtime historyWin->update,'No OMNI Data Loaded, OMNI data is only available between ' + omnimintime + ' and ' + omnimaxtime endif else begin if new_vars[0] ne '' then begin loaded = 1 ; loop over loaded data for i = 0,n_elements(new_vars)-1 do begin ; check if data is already loaded, if so query the user on whether they want to overwrite data spd_ui_check_overwrite_data,new_vars[i],loadedData,parent_widget_id,statusBar,historyWin,overwrite_selection,overwrite_count,$ replay=replay,overwrite_selections=overwrite_selections if strmid(overwrite_selection, 0, 2) eq 'no' then continue ; this statement adds the variable to the loadedData object which is ; used by many other panels to display the variables that are available to the GUI result = loadedData->add(new_vars[i],mission='omni',observatory='omni',instrument='omni') ; report errors to the status bar and add them to the history window if ~result then begin statusBar->update,'Error loading: ' + new_vars[i] historyWin->update,'OMNI: Error loading: ' + new_vars[i] return endif endfor endif endelse ; here's where the temporary tplot variables are removed if to_delete[0] ne '' then begin store_data,to_delete,/delete endif ; inform the user that the load was successful and add it to the history if loaded eq 1 then begin statusBar->update,'OMNI Data Loaded Successfully' historyWin->update,'OMNI Data Loaded Successfully' endif end
