4 GEANT/GRAPHICS˙CONTROL Graphics control commands. 4.1 DOPEN iview IVIEW I “View number” CALL GDOPEN(iview) When a drawing is very complex and requires a long time to be executed, it can be useful to store it in a view bank: after a call to DOPEN and the execution of the drawing (nothing will appear on the screen), and after a necessary call to DCLOSE, the contents of the bank can be displayed in a very fast way through a call to DSHOW; therefore, the detector can be easily zoomed many times in different ways. Please note that the pictures with solid colours can now be stored in a view bank or in ’PICTURE FILES’. 4.2 DSHOW [ iview ] IVIEW I “View number” CALL GDSHOW(iview) It shows on the screen the contents of a view bank. It can be called after a view bank has been closed. 4.3 DELETE iview IVIEW I “View number” CALL GDELET(iview) It deletes a view bank from memory. 4.4 DCLOSE CALL GDCLOS It closes the currently open view bank; it must be called after the end of the drawing to be stored. 4.5 CHANGEWK CALL GCHNWK It open a new workstation (if not already opened) and activate it (deactivating the default one). 4.6 RESETWK CALL GRESWK It deactivate the previosly activated workstation and reactivate the default one. 4.7 SSETAT iopt IOPT C “Attribute name” XINT002 – 18 374
Set current attribute. 4.8 SSETVA [ rval ] RVAL R “Attribute value” D=1. R=-10.:10. Set current attribute value. 4.9 SATT [ name iopt ival ] NAME C “Volume name” D=’* ’ IOPT C “Name of the attribute to be set” D=’DEFA’ IVAL I “Value to which the attribute is to be set” D=10000 CALL GSATT(name,iopt,ival) name=’*’ stands for all the volumes. iopt can be chosen among the following : ’WORK’ ’SEEN’ ’LSTY’ ’LWID’ ’COLO’ ’m’; ’m’; ’m’; ’m’; ’m’; ’m’; 0=volume name is inactive for the tracking 1=volume name is active for the tracking (default) 0=volume name is invisible 1=volume name is visible (default) -1=volume invisible with all its descendants in the tree -2=volume visible but not its descendants in the tree line style 1,2,3,... (default=1) LSTY=7 will produce a very precise approximation for revolution bodies. line width -7,...,1,2,3,..7 (default=1) LWID
