Inserts a child item in sorted order under the parent item.
Description
Inserts an item in sorted order, if possible.
Applies to
TreeView controls
Syntax
treeviewname.InsertItemSort ( handleparent, label, pictureindex )
|
Argument |
Description |
|---|---|
|
treeviewname |
The TreeView control in which you want to insert and sort an item as a child of its parent, according to its label. |
|
handleparent |
The handle of the item that will be the inserted item's parent. To insert the item at the first level, specify 0. |
|
label |
The label by which you want to sort the item as a child of its parent. |
|
pictureindex |
The picture index for the item you want to sort as a child of its parent, according to its label. |
Return value
Long.
Returns the handle of the item inserted if it succeeds and -1 if an error occurs.
Usage
If SortType is anything except Unsorted!, the TreeView is always in a sorted state and you do not need to use InsertItemSort -- you can use any insert function.
If SortType is Unsorted!, InsertItemSort attempts to insert the item at the correct place in alphabetic ascending order. If the list is out of order, it does its best to find the correct place, but results may be unpredictable.
Examples
This example populates the fourth level of a TreeView control:
long ll_lev1, ll_lev2, ll_lev3, ll_lev4 int index tv_list.PictureHeight = 32 tv_list.PictureWidth = 32 ll_lev1 = tv_list.InsertItemLast(0,"Composers",1) ll_lev2 = tv_list.InsertItemLast(ll_lev1,& "Beethoven",2) ll_lev3 = tv_list.InsertItemLast(ll_lev2,& "Symphonies",3) FOR index = 1 to 9 ll_lev4 = tv_list.InsertItemSort(ll_lev3, & "Symphony # " + String(index), 4) NEXT tv_list.ExpandItem(ll_lev3) tv_list.ExpandItem(ll_lev4)
