forms 中层次树的使用方法


  本例子附有create tabel 及insert 数据的sql 及forms的源文件, 经测试可以直接运行。
  
  运行界面如下:
  

  trigger; WHEN-NEW-FORMS-INSTANCE: 
  
  set_window_property('window1', window_state, maximize);
  declare
   rg1 recordgroup;
   t number;
   uname varchar2(32);
  BEGIN
  :global.os := get_application_property(Operating_system);
  
  rg1 := find_group('RG1');
  if not id_null(rg1) then
   delete_group(rg1);
  end if;
  uname := user;
  :vdata := uname;
  uname := lower(uname);
  rg1 := create_group_from_query('RG1','select init,depth,lpad(substr(treeno,-1,2),2,''0'')||''.''||label,'''',data from menu order by treeno');
  t := populate_group(rg1);
  ftree.set_tree_property('TREE',Ftree.record_group, rg1);
   --psize();
  END;
  
  trigger; WHEN-TREE-NODE-ACTIVATED: 
  
  
  DECLARE 
   htree         ITEM; 
   node_value    VARCHAR2(100); 
   ftype        varchar2(8); 
  BEGIN 
  node_value := Ftree.Get_Tree_Node_Property('TREE', :SYSTEM.TRIGGER_NODE, Ftree.NODE_VALUE); 
  
  ftype:=lower(substr(node_value,-1,3)); 
  --ftype:='fmx'; 
  if node_value <>'node' then 
  if ftype = 'fmx' then 
  call_form(node_value ,no_hide); 
  elsif ftype = 'sql' then -- execute those sql need not parameter -- 
  host('plus80w @'||:vdata, NO_SCREEN); 
  end if; 
  end if; 
  END;
