I have a pane with tree control in it. Once hovering on the pin button, the tree become gray. I tried a solution that is mentioned here putting the styles WS_CLIPCHILDREN and WS_CLIPSIBLINGS to the mainframe, the pane view and the tree control BUT... with no help.

Any other ideas?

Hello,

Try to isolate problem in little sample and attach it here. I sure problem in styles. Check in Spy++ that windows have these clip styles.

I checked with Spy++ and WS_CLIPCHILDREN and WS_CLIPSIBLINGS exists in the tree control, its parent pane window, the pane's parent pane manager and the main frame.

Anyway, here is a snapshot of the code:

int CMainFrame::OnCreate(LPCREATESTRUCT lpCreateStruct) {

...

m_paneManager.InstallDockingPanes(this);

m_paneManager.SetTheme(xtpPaneThemeOffice);

// Create the repository pane and window

CXTPDockingPane* pDockedRepositoryWnd = m_paneManager.CreatePane(IDC_REPOSITORY_PANE, CRect(0, 0, 200, 120), dockLeftOf);

if( pDockedRepositoryWnd != NULL )

{

pDockedRepositoryWnd->SetIconID(1);

pDockedRepositoryWnd->SetTitle("Repository");

}

pDockedRepositoryWnd->Attach(m_repositoryPane.CreatePane(this));

.....

}

m_repositoryPane is CMainFrame class member that derives from

CPaneWnd and holds a member of its own,

m_repositoryTreeCtrl, which derives from CTreeCtrl.

Here is the creation of the pane window:

CWnd* CRepositoryView::OnCreateView()

{

if( m_repositoryTreeCtrl.m_hWnd == NULL )

{

{

m_repositoryTreeCtrl.ModifyStyle(TVS_SINGLEEXPAND, 0); // remove single item expansion

ModifyStyleEx(0, WS_EX_TRANSPARENT);

}

EnableToolTips();

return &m_repositoryTreeCtrl;

}

I hope it helps...

Hi,

guess this is because you attach only in OnCreate:

pDockedRepositoryWnd->Attach(m_repositoryPane.CreatePane(this));

you must attach it in OnDockingPaneNotify handler. please follow our samples.

Well, it was simpler than that.

The pane class was created with WS_EX_TRANSPARENT (see above) which caused the problems. Once the style was removed, the pane refresh correctly.
