FOLDER

一、建noTab的Folder Form:
1.创建数据库对象:
  create table  和相应的view。

2.基于模板Template.fmb创建一个新的Form:****.fmb
  添加一个Library:APPFLDR.pll(目录:$AU_TOP/Resource;打开后,系统询问是否去掉绝对路径,选择YES)
  再打开APPSTAND.fmb:将其中的对象组STANDARD_FOLDER拖到自己的FORM中,选择Subclass

3.添加窗口 window:
  设置属性:Subclass information:WINDOW

4.添加画布:MAIN(内容画布) 和 CANVAS(堆叠画布)
   MAIN的type为content ;
   CANVAS的type为stacked
           subclass:canvas_Stacked

5.添加数据块:block(基于数据库)、 block_prompt(放Title)
  设置对应属性:subclass都为BLOCK
                画布block :Number of Records Displayed--8
                            ShowScrolbar--YES
                            Scrollbar Canvas-- MAIN 设置滚动条显示的画布
========== 以下对数据块block:======
6.添加触发器:
  对数据块block:添加支持FOLDER的Block级的Trigger:
  PRE-QUERY -- app_folder.event('PRE-QUERY');
  POST-QUERY -- app_folder.event('POST-QUERY');
                app_globe.event('POST-QUERY');
  WHEN-NEW-BLOCK-INSTANCE    app_folder.event('WHEN-NEW-BLOCK-INSTANCE');
  WHEN-NEW-RECORD-INSTANCE   app_folder.event('WHEN-NEW-RECORD-INSTANCE');
app_folder.event('KEY-PREV-ITEM');          
app_folder.event('KEY-NEXT-ITEM');
app_folder.event('KEY-PRVREC');
app_folder.event('KEY-NXTREC');
app_folder.event('KEY-CLRREC');
app_folder.event('KEY-EXEQRY');
app_folder.event('KEY-ENTQRY');
app_folder.event('PRE-BLOCK');
app_folder.event('POST-BLOCK');
app_folder.event('KEY-CLRBLK');
pre-insert    fnd_standard.set_who;
7.添加ITEM: Folder_Switcher and CURRENT_RECORD_indicator
  注:这两个item要放置在块的最上面。
  设置属性:SWITCHER:
            item type:TEXT ITEM
            SUBCLASS : SWITCHER
            VISIBLE : yes
            canvas   :显示在堆叠画布CANVAS
            PROMPT   : 空
       ------------------------------
            indicator:
            ITEM TYPE: TEXT ITEM
            SUBCLASS : CURRENT_RECORD_INDICATOR
            VISIBLE  : YES
            CANVAS   : 显示在内容画布MAIN
            PROMPT   : 空
========== 以下对数据块block_prompt:======
8.添加6个FOLDER特有的Item
注:放在block中的下方,顺序为:by321 dummy title open
                itemtype      subclass     visible      canvas
FOLDER_OPEN :    push        folder_open     yes         MAIN
FOLDER_TITLE:   Display     dynamic_title    yes         MAIN
FOLDER_DUMMY:    TEXT        FOLDER_DUMMY    YES        TOOLBAR
ORDER_BY1:       PUSH        FOLDER_ORDERBY   NO         CANVAS
ORDER_BY2:       push        FOLDER_ORDERBY   no         canvas
ORDER_BY3:      push        FOLDER_ORDERBY   NO         CANVAS

9.添加与基于数据库的block中的要显示的item对应的用于显示title的item
注:必须与之同名,宽度必须一致,且在block中的上下顺序一致。
  设置属性:ITEMtype : Display Item
            subclass : FOLDER_PROMPT_MULTIROW
            InitialValue:需要显示的名称
10.更改App_custom Package 中的一些代码:
   将wnd='****' ---改为自己的窗口名:WINDOW
           
11.更改Form级Trigger
   pre-form: app_window.set_window_position('WINDOW','FISRT_WINDOW');--是显示的第一个窗口
12.设置窗口的primary Canvas 为 主画布MAIN

13.添加PACKAGE: Form_pkg
===============================================================
PACKAGE BODY Form_pkg IS
   procedure  new_form_instance is
begin

   --定义Folder
     app_folder.define_folder_block('Cup_ORDER_4040_2',--客户化自定义名
    'block',--folder_block_name
    'block_prompt',--prompt_block_name
     'canvas',--folder_canvas_name
     'window',--folder_window_name
      null,--disabled_functions
      null,--tab_canvas_name
       null);--fixed_canvas_name
    app_folder.event('INSTANTIATE');
  SYNCHRONIZE;
   end;
END;

================================
14.更改Form级trigger
 
when-new-form-instance :
FDRCSID('$Header: TRNORD4040.fmb 120.0 2005/05/06 23:25  appldev ship                                                                                                                                                                                                                                                                    $');
APP_STANDARD.EVENT('WHEN-NEW-FORM-INSTANCE');
form_pkg.new_form_instance;
 
folder_action:  
app_folder.event(:global.folder_action);
 
when-window-resized: 
if :system.event_window in ('ORDER_MAIN') then
  app_folder.event('WHEN-WINDOW-RESIZED');
end if;

key-CLRFRM :
APP_STANDARD.EVENT('KEY-CLRFRM');
app_folder.event('KEY-CLRFRM');

   更改Item级trigger
folder_switcher:  when-new-item-instance : app_folder_move_cursor('1');
current_record_indicator:   when-new-item-instance:  app_folder_move_cursor('1');

 

 

二、建有Tab的Folder Form:

 

*与非tab不同之处:
1.固定列不再放在内容画布上,而是放在子类型为canvas_stacked_fix_field的堆叠画布上
2.API定义Folder时的参数不同,需指定:tab_canvas_name,fixed_canvas_name 两个参数

2.基于模板Template.fmb创建一个新的Form:****.fmb

  再打开APPSTAND.fmb:将其中的对象组STANDARD_FOLDER拖到自己的FORM中,选择Subclass

3.添加窗口 window:
  设置属性:Subclass information:WINDOW

4.添加画布:MAIN(内容画布) 和 CANVAS(堆叠画布)
   CANVAS的subclass:canvas_Stacked
  添加Tab类型的画布MAIN_Tab
  设置属性:CanvasType: Tab 
            subclass  :TAB_CANVAS
            VISIBLE   : YES
            WINDOW    :window
  对标签页设置label(显示标题) 、设置subclass为TAB_PAGE


5.添加数据库:block(基于数据库)、 block_prompt(放Title)
  设置对应属性:subclass都为BLOCK
                画布block :Number of Records Displayed--8
                            ShowScrolbar--YES
                            Scrollbar Canvas-- ***FIX 设置垂直滚动条显示的画布(为fix画布)
========== 以下对数据块block:======
6.添加触发器:
  对数据块block:添加支持FOLDER的Block级的Trigger:
  PRE-QUERY -- app_folder.event('PRE-QUERY');
  POST-QUERY -- app_folder.event('POST-QUERY');
                app_globe.event('POST-QUERY');
  WHEN-NEW-BLOCK-INSTANCE    app_folder.event('WHEN-NEW-BLOCK-INSTANCE');
  WHEN-NEW-RECORD-INSTANCE   app_folder.event('WHEN-NEW-RECORD-INSTANCE');
app_folder.event('KEY-PREV-ITEM');          
app_folder.event('KEY-NEXT-ITEM');
app_folder.event('KEY-PRVREC');
app_folder.event('KEY-NXTREC');
app_folder.event('KEY-CLRREC');
app_folder.event('KEY-EXEQRY');
app_folder.event('KEY-ENTQRY');
app_folder.event('PRE-BLOCK');
