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.

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.

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.
