 Topic: BUG: Redraw problems with CXTPTreeCtrlPosted: 28 December 2016 at 8:27am |

This is new for the latest release:
When I scroll the contents of a CXTPTreeCtrl horizontally, it does not update correctly, leaving reminders of the tree lines:  The tree is in a XTP Docking Panel. Resizing the panel to force a redraw solves the problem. My code is unchanged except for updating it to use the latest version of XTP. I see a change in void CXTPTreeBase::DrawItem(CDC *pDC, HTREEITEM hItem), the line rcExpander.OffsetRect(-XTP_DPI_X(XTP_TREE_ICON_IDENT), 0); has been added. Maybe the offset is not right? |

When I replace the CXTPTreeBase::DrawItem and CXTPTreeBase::GetItemExpanderRect with the implementations from the 17.2 edition of XTP, the drawing problem is gone.
So the changes introduced in the current version are causing this. |

Artem,
that's good news. Can you share a patch I can include in the 17.3 release? Otherwise I need to ship my software the code from the 17.2 I've included. |
