Onkeydown() event in CXTTreeBase

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Hi there,

I've got a CXTTree based class. I capture the OnKeyDown() event and it works fine.

When I navigate the tree with arrows up and down(even with SHIFT pressed), I capture the event, I get the list of selected items and refresh some information for all of them.

But, when I try to navigate the tree with the first letter of an item (pressing character 'c' to go to car...and so), list of selected items is empty so I can't do anything with it. 

Is like the event launches after the selection of the next item with arrows, but before the selection of the next item with an alphanumeric character..

Is this a bug or am I doing something wrong?

This my code in OnKeyDown() method, if it helps

"void CMyClassView::OnKeyDown(UINT nChar, UINT nRepCnt, UINT nFlags)

{
CXTTreeView::OnKeyDown(nChar, nRepCnt, nFlags);

tSetLong setSelectedTags;

long lFocusedTag= -1L;

CTreeCtrl &rTree= GetTreeCtrl();
CTypedPtrList<CPtrList, HTREEITEM> listItems;

GetSelectedList(listItems);
POSITION pos= listItems.GetHeadPosition();
while (pos != NULL)

{
HTREEITEM hti= listItems.GetNext(pos);
if (hti != NULL)

{
long lCode= rTree.GetItemData(hti);

setSelectedItems.insert(lCode);
HTREEITEM hti= GetFocusedItem();
TreeSelectionHasChanged(lFocusedTag);
}
}"

	Hi, Think you need TVN_SELCHANGED notification. User can select item with mouse also...
	Oleg, Support Team CODEJOCK SOFTWARE SOLUTIONS
