How to control which panes a pane can attach to?

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   I am trying to keep a set of panes from attaching to a specific pane (IDR_PANE_OUTPUT_BAR).
I know this is handled by setting the bCancel member of the XTP_DOCKINGPANE_ACTION to false in the  OnDockingPaneNotify message handler when wParam is XTP_DPN_ACTION, and the action member of the XPT_DOCKINGPANE_ACTION is xtpPaneActionAttaching.  The problem I am having is determining if the pane that is going to have the new pane added already contains the IDR_PANE_OUTPUT_BAR pane.  I have the following OnDockingPaneNotify message handler:

Pane ID's

#define IDR_PANE_PROJECT 4000
#define IDR_PANE_BACKGROUND 4001
#define IDR_PANE_COORDINATES 4002
#define IDR_PANE_STACKER 4003
#define IDR_PANE_LEGEND 4004
#define IDR_PANE_VIEW_EXTENTS 4005
#define IDR_PANE_OUTPUT_BAR 4006

LRESULT CMainFrame::OnDockingPaneNotify(WPARAM wParam, LPARAM lParam)
{

switch (wParam) {

case XTP_DPN_SHOWWINDOW:

{

CXTPDockingPane* pPane = (CXTPDockingPane*)lParam;
if (!pPane->IsValid()) {

switch (pPane->GetID()) {

case IDR_PANE_PROJECT:

if (NULL == m_pMapObjectView) {

m_pMapObjectView = DYNAMIC_DOWNCAST(CMapObjectView,pPane->AttachView(this,RUNTIME_CLASS(CMapObjectView)));

} else {

pPane->Attach(m_pMapObjectView->GetParent());
}
break;

case IDR_PANE_BACKGROUND:

if (NULL == m_pBackgroundCtrl) {

m_pBackgroundCtrl = DYNAMIC_DOWNCAST(CBackgroundCtrl, pPane->AttachView(this,RUNTIME_CLASS(CBackgroundCtrl)));

} else {

pPane->Attach(m_pBackgroundCtrl->GetParent());
}
break;

case IDR_PANE_LEGEND:

if (NULL == m_pLegendCtrl) {

m_pLegendCtrl = DYNAMIC_DOWNCAST(CLegendCtrl,pPane->AttachView(this,RUNTIME_CLASS(CLegendCtrl)));

} else {

pPane->Attach(m_pLegendCtrl->GetParent());
}
break;

case IDR_PANE_STACKER:

if (NULL == m_pStackerCtrl) {

m_pStackerCtrl = DYNAMIC_DOWNCAST(CStackerCtrl,pPane->AttachView(this,RUNTIME_CLASS(CStackerCtrl)));

} else {

pPane->Attach(m_pStackerCtrl->GetParent());
}
break;

} else {

pPane->Attach(m_pViewExtentsCtrl->GetParent());
}
break;

case IDR_PANE_OUTPUT_BAR:

if (NULL == m_pOutputBar) {

m_pOutputBar = new COutputBarD(this);

}
if (0 == m_pOutputBar->GetSafeHwnd()) {

m_pOutputBar->Create(this);

}
pPane->Attach(m_pOutputBar);
break;

}

}
return true;

}
break;

case XTP_DPN_ACTION:

{

XTP_DOCKINGPANE_ACTION* pAction = (XTP_DOCKINGPANE_ACTION*)lParam;
UINT nID = pAction->pPane->GetID();
switch (pAction->action) {

case xtpPaneActionAttaching:

{

TRACE("Action Pane %d\n",nID);

TRACE("Dock Container Type %s\n",strPaneType[pAction->pDockContainer->GetType()]);

if  (IDR_PANE_OUTPUT_BAR == nID)  {

pAction->bCancel = true;

return true;

} else if ((IDR_PANE_PROJECT <= nID) && (IDR_PANE_VIEW_EXTENTS >= nID)) {

if (xtpPaneTypeTabbedContainer == pAction->pDockContainer->GetType()) {

CXTPDockingPaneTabbedContainer *tc = (CXTPDockingPaneTabbedContainer*)pAction->pDockContainer;
// if docking site contains IDR_PANE_OUTPUT_BAR or any pane other than IDR_PANE_PROJECT,
// IDR_PANE_BACKGROUND, IDR_PANE_COORDINATES, IDR_PANE_STACKER, IDR_PANE_LEGEND, 
// IDR_PANE_VIEW_EXTENTS pAction->bCancel = true;
// Can't figure out what to do here,  the provided documentation is minimal
}

} else {

// keep rest of panes from attaching to any other pane
pAction->bCancel=true;
}

pAction->bCancel=FALSE;
return true;

	I Figured it out, here's the code case XTP_DPN_ACTION: { XTP_DOCKINGPANE_ACTION* pAction = (XTP_DOCKINGPANE_ACTION)lParam; UINT nID = pAction->pPane->GetID(); if (xtpPaneActionAttaching == pAction->action) { if ((IDR_PANE_PROJECT <= nID) && (IDR_PANE_VIEW_EXTENTS >= nID)) { if (xtpPaneTypeTabbedContainer == pAction->pDockContainer->GetType()) { CXTPDockingPaneTabbedContainer tc = (CXTPDockingPaneTabbedContainer)pAction->pDockContainer; CXTPDockingPane fp = (CXTPDockingPane*)tc->GetFirstPane(); UINT pID = fp->GetID(); if ((IDR_PANE_PROJECT <= pID) && (IDR_PANE_VIEW_EXTENTS >= pID)) { pAction->bCancel = false; } else { pAction->bCancel = true; } } } else { pAction->bCancel = true; } return true; } } break;
