pfc里面的树也么设计成不限层的！

[lslyl]

谢了。

[青锋-SS]

pfc?一直没找到过.帮你顶.能否给上一份?

[zhangdatou]

我没研究过pfc

[alwaystar]

你说的是递归吗？
of_SetDataSource( integer ai_level, string as_datawindow, n_tr atr_obj, string as_labelcolumn, string as_retrieveargs, boolean ab_recursive, integer ai_pictureindex, integer ai_selpictindex, integer ai_statepictindex, integer ai_overlaypictindex )

其中boolean ab_recursive就是代表是否采用递归方式设置数据源！

[alwaystar]

当然你的数据源(数据窗口)的检索参数必须符合递归的

[lslyl]

举个例子.听听.

[lslyl]

//Level 3
tv_1.inv_levelsource.of_Register(3, "deptname", ":parent.1.deptid", "d_hr_lv_group", SQLCA, "")
tv_1.inv_levelsource. of_SetRecursive(3, TRUE) //递归
tv_1.inv_levelsource.of_SetPictureColumn(3, "1")
tv_1.inv_levelsource.of_SetSelectedPictureColumn(3, "2")
这样不行吗.

[alwaystar]

你用的是哪个版本的PFC呀
tv_1.of_SetDataSource(....)

[lslyl]

9.0的呀.我想知道如果这个是递归了,可是下面又要加新层怎么作.哈哈.

//开启
tv_1.of_setlevelsource(true)
// 1层
li_rc = tv_1.inv_levelsource.of_Register(1, "proc_name", "", "d_stock", SQLCA, "")
// 2层
li_rc = tv_1.inv_levelsource.of_Register(2, "stock_desc", "", "d_stock_type", SQLCA, "")
// 3层
li_rc = tv_1.inv_levelsource.of_Register(3, "grp_desc", "", "d_grp", SQLCA, "")
// 4层

// 5层
li_rc = tv_1.inv_levelsource.of_Register(5, "item_num", ":level.4.item_type", "d_mst_rol_arg", SQLCA, "")

// 6层
li_rc = tv_1.inv_levelsource.of_Register(6, "", "", "", SQLCA, "")
tv_1.inv_levelsource.of_setpicturecolumn(6, "3")
tv_1.inv_levelsource.of_setselectedpicturecolumn(6, "4")


li_rc = tv_1.event pfc_populate(0)
ll_firstitemonlevel = tv_1.inv_base.of_FindFirstItemLevel(1, 0)
tv_1.SelectItem(ll_firstitemonlevel)
tv_1.ExpandItem(ll_firstitemonlevel)

[lslyl]

up呀.

[zhangdatou]

不客气

pfc 的树就是这样被使用的 就是数据源，参数的使用。与你的数据逻辑关系有很大关系的。
