Description
The picture event is being generated by the defined displayer of Browser type, when the user click an item of the browser. The item is identified by its row (the parameter _row) and its column (the parameter _col).
The parameter _btnNr identifies the pressed mouse button according to the following table:
 
_mouseBtn Mouse button
1 Left
2 Middle
3 Right

Example
Special picture event handler:
 
?
ENTRY brw1_OnBrowserClick(IN  INT _mouseBtn, IN  BOOL _dblClick, IN  INT _row, IN  INT _col, IN  BOOL _bShift, IN  BOOL _bCtrl)
 %HI_AddItem(_lst, "brw1_OnBrowserClick")
 %HI_AddItem(_lst, " _mouseBtn = " + %IToStr(_mouseBtn))
  
 IF _dblClick THEN
 %HI_AddItem(_lst, " _dblClick = TRUE")
 ELSE
 %HI_AddItem(_lst, " _dblClick = FALSE")
 ENDIF
  
 %HI_AddItem(_lst, " _row = " + %IToStr(_row))
 %HI_AddItem(_lst, " _col = " + %IToStr(_col))
  
 IF _bShift THEN
 %HI_AddItem(_lst, " _bShift = TRUE")
 ELSE
 %HI_AddItem(_lst, " _bShift = FALSE")
 ENDIF
  
 IF _bCtrl THEN
 %HI_AddItem(_lst, " _bCtrl = TRUE")
 ELSE
 %HI_AddItem(_lst, " _bCtrl = FALSE")
 ENDIF
 END brw1_OnBrowserClick

Note
If both the handlers are defined in picture script, the global handler will never be called for _refId=_brw1, because a special handler is already defined.
