I am trying to put CListView and CTreeView controls into a CXTPTaskPanel. Each list or tree control will be the only item in a group.

My problem is that I would like the tree and list controls to resize to use all of the available space when their group is active. This seems hard.

Can anyone point to sample code which does this?

The CXTPTaskPanel will also be resizeable.

thank you;

Hi,

I do not know if the lastest updates have this "fixed" or not, but in the 9.80 I had do to this...

I'm not sure if it's 100% correct...

void CMyTaskPanel::UpdateScrollBar()
{

if ( !IsExplorerBehaviour() )
{

  int nClientHeight = CXTPClientRect(this).Height();

  if ( nClientHeight > 0 )
  {

bool bDefault;
bDefault = false;

   for ( int i = 0; ( i < GetGroups()->GetCount() ) && !bDefault; ++i )
   {

    CXTPTaskPanelGroup* pGroup = GetAt(i);

    if ( pGroup->IsExpanding() ) continue;

    CRect rcGroup = pGroup->GetTargetClientRect();

    for ( int j = 0; ( j < pGroup->GetItemCount() ) && !bDefault; ++j )
    {

     CXTPTaskPanelGroupItem *pItem = (CXTPTaskPanelGroupItem*)pGroup->GetAt(j);

     if ( !pItem || pItem->GetType() != xtpTaskItemTypeControl )
     {

      bDefault = true;

      break;
     }

     int nItemHeight = rcGroup.Height() - 2;

     if ( pItem->GetItemRect().Height() != nItemHeight )
     {


      ::SetWindowPos( pItem->m_hWnd, 0, pItem->GetItemRect().left, pItem->GetItemRect().left, pItem->GetItemRect().Width(), nItemHeight, SWP_NOZORDER );

if ( !pGroup->IsExpanding() )

       pItem->SetSize(CSize(0, nItemHeight), false );

     }
    }

   }
  }

}

    //

CXTPTaskPanel::UpdateScrollBar();

} // UpdateScrollBar

Thank you for your reply. It is no longer an issue for me for two reasons:

1) my boss decided he wants different behavior

2) Oleg Chernyahovskii of codejock.com mailed me a much simpler answer:

Solution: -------------------------------------------

Hi,

just call

pItem->SetSize (CSize(x, 0), TRUE);

method declaration:

void SetSize(CSize szItem, BOOL bAutoHeight = FALSE);

-----------------------------------------

This gives the behavior I wanted - the CListView / CTreeView item automatically sizes to use the full vertical height available to the group. Unfortunately it doesn't size to take advantage of the full horizontal width available, but if I use CSize( 2000, 0 ) then the controls are wide enough for any practical CXTPTaskPanel, and they grow horizontal scroll bars when needed and behave sensibly.

Thank you;
