Hello,
Is there a way to add a Tri State Checkbox to the CXTTreeCtrl ? I also need a normal image. i use 11.1.3. I known its work with Markup ext. on version 12.0.0. But we can't wait. Jimmy |

Hi,
First add own STATE image list m_imageState.Create( 16, 15, ILC_COLOR32 | ILC_MASK, 0, 1); CBitmap bmp; bmp.LoadBitmap(IDB_TRI_STATE_TREE); m_imageState.Add(&bmp, RGB(0,255,255)); SetImageList( &m_imageState, TVSIL_STATE ); int CTriStateTreeCtrl::GetCheck(HTREEITEM hItem) const { return (GetItemState( hItem, TVIS_STATEIMAGEMASK )>>12) - 1; } void CTriStateTreeCtrl::SetCheck(HTREEITEM hItem, int iState) { SetItemState( hItem, INDEXTOSTATEIMAGEMASK(iState+1), TVIS_STATEIMAGEMASK ); RedrawItem(hItem); // TRACE("SetCheck=%u\n", iState); } Bitmap: width = x*16Pixel, height = 15Pixel. 1.icon not used, 2. uncheck, 3.checked, 4.TriState, and other .... Sorry Codejock does not allowed upload bitmap at this time. Also must catch LButtonDown & check TVHT_ONITEMSTATEICON to toggle Check state. Don't forget to catch KEYDOWN-Space to toggle Check state. uploads/20080220_054307_Test_TriStateTr.zip Jimmy |

The MFC TreeCtrl sample demonstrates how to use a tri-state tree control. Run the sample, you will see the tri-state tree control on the right side of the dialog.
 Open the project and look at the "CStateTreeCtrl" class, hope this helps.
