CMarkupTreeCtrl problem

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

   XTP 13.1.

CMarkupTreeCtrl is owner-drawn. This means the width of the items is not set (since Windows does not draw it) which leads to a missing horizontal scrollbar. The control is not wide enough to show my items, and I have to make sure the tree control becomes aware of this and then shows a properly scaled horizontal scrollbar.

I've searched the whole net. Can't find information about this (which is odd).

Any ideas?

	Solved it! Replacing your "NULL" with the actual text of the item does the trick. Windows seems to calculate the widths upon the InsertItem call! --------------------------------------------------------------------------- CString GetInnerText(CXTPMarkupObject* pParent); HTREEITEM CMarkupTreeCtrl::AddItem(LPCTSTR lpszItem, int nImage, int nSelectedImage, HTREEITEM hParent/* = TVI_ROOT/, HTREEITEM hInsertAfter/ = TVI_LAST/) { CXTPMarkupUIElement pUIElement = Parse(lpszItem); HTREEITEM hItem; if (pUIElement) { hItem = InsertItem(GetInnerText(pUIElement), nImage, nSelectedImage, hParent, hInsertAfter); SetItemData(hItem, (DWORD_PTR)pUIElement); } else { hItem = InsertItem(lpszItem, nImage, nSelectedImage, hParent, hInsertAfter); } return hItem; }

	Yeah, but what happens if you have a different font in the markup? Then the width will not match, right? In general, I think the native Windows tree control is a disaster :(
