;+ ;NAME: ; thm_ui_load_omni_data ; ;PURPOSE: ; This routine is an example of how to build a load data panel and handle the ; widget events it produces. This is a template only and creates basic widgets ; that are common to most missions. ; Each mission is different. Some widgets may need to be added to fully specify ; the data set to be loaded or some may not be needed. ; ;HISTORY: ;$LastChangedBy: crussell $ ;$LastChangedDate: 2013-01-09 08:29:50 -0800 (Wed, 09 Jan 2013) $ ;$LastChangedRevision: 11403 $ ;$URL: svn+ssh://thmsvn@ambrosia.ssl.berkeley.edu/repos/thmsoc/tags/tdas_8_00/idl/themis/thm_ui_new/panels/thm_ui_load_data_file/thm_ui_load_omni_data.pro $ ; ;-------------------------------------------------------------------------------- pro thm_ui_load_omni_data_event,event compile_opt hidden,idl2 ;handle and report errors, reset variables err_xxx = 0 Catch, err_xxx IF (err_xxx NE 0) THEN BEGIN Catch, /Cancel Help, /Last_Message, Output = err_msg if is_struct(state) then begin ;send error message FOR j = 0, N_Elements(err_msg)-1 DO state.historywin->update,err_msg[j] if widget_valid(state.baseID) && obj_valid(state.historyWin) then begin thm_gui_error,state.baseid,state.historyWin endif ;update central tree, if possible if obj_valid(state.loadTree) then begin *state.treeCopyPtr = state.loadTree->getCopy() endif ;restore the state structure Widget_Control, event.TOP, Set_UValue=state, /No_Copy endif Print, 'Error--See history' ok=error_message('An unknown error occured and the window must be restarted.
