Hello,

I am putting a CXTDockingPane on a CMyDockBar(derived from CXTDockingPaneManager)

After this i am putting a Taskpanel on this Docking pane.

Now when user resizes the pane, i want to handle it.
Which Handler should i be using and for which class ?????

Thanks Oleg,

Can i store the size of this taskpanel in registry, so that when my application will restart user will see the last size he set.

Hi,

You have save layout of DockingPanes. See our samples - they show how.

Thanks,
I checked the example of how to save the layout.

Now i am geting into another problem
I have class:
class CDockBar : public CXTPDockingPaneManager
{
public:
   CmcTaskPanel   m_wndTaskPanel;
   CXTPDockingPane* m_pDocPane;
   CXTPDockingPaneLayout* m_pCmcLayout;

}

Now in the create function of CDockBar :
I create the taskpanel.
I create the pane
and i attach the taskpane to this pane.

Now when i do this:
   m_pCmcLayout = this->CreateLayout();
   if (m_pCmcLayout->Load(_T("AmitLayout")))
   {
       this->SetLayout(m_pCmcLayout);
   }
   else
   {
       this->GetLayout(m_pCmcLayout);
   }
When before it executes the call to SetLayout, the m_pDocPane shows its class in the Add-Watch of VC6 as {CXTPDockingPane}.
But as soon as the SetLayout calls is executed, the m_pDocPane shows its class in add watch as {CXTPTabManager::CNavigateButtonArrowRight}.
Why the class changes ???

Due to this my application crashes later when i call m_pDocPane->Select(); // In the GetDockingPaneManager() it shows the value of m_pLayout as NULL.

Yes, after SetLayout call m_pDocPane is destroyed. Don't save pointers. Use FindPane method instead.

Hello Oleg,
Using FindPane() Worked fine for me :) Thanks...

Though the problem of the pointer is solved, i am not able to restore the size when i open the application next time.

This is what i am doing. Please tell me if the steps are correct.

In OnCreate()::::

    if (!m_wndTaskPanel.GetSafeHwnd())
    {
        if (!m_wndTaskPanel.Create(WS_CHILD|WS_VISIBLE|WS_CLIPSIBLINGS|WS_CLIPCHILDREN, CRect(0, 0, 0, 0), /*this*/ pWnd, 0))
            return FALSE;

        m_wndTaskPanel.SetOwner(pWnd);//this);

        m_wndTaskPanel.SetTheme(xtpTaskPanelThemeNativeWinXP);//xtpTaskPanelThemeShortcutBarOffice2003);
        m_wndTaskPanel.SetHotTrackStyle(xtpTaskPanelHighlightImage/*xtpTaskPanelHighlightItem*/);
        m_wndTaskPanel.SetSelectItemOnFocus(TRUE);
        //m_wndTaskPanel.SetSingleSelection();
        m_wndTaskPanel.SetItemLayout(xtpTaskItemLayoutImagesWithText);//xtpTaskItemLayoutImagesWithTextBelow);
        m_wndTaskPanel.AllowDrag(FALSE);
        m_wndTaskPanel.SetBehaviour(xtpTaskPanelBehaviourList);
    }

    this->InstallDockingPanes(pWnd);
    this->SetTheme(xtpPaneThemeNativeWinXP/*xtpPaneThemeShortcutBar2003*/);

    m_pDocPane = this->CreatePane(ID_PANE, CRect(0, 0, 150, 150), xtpPaneDockLeft);
    m_pDocPane->SetOptions(xtpPaneNoCloseable | xtpPaneNoHideable | xtpPaneNoFloatable | xtpPaneNoDockable | xtpPaneNoCaption);

    m_pDocPane->Attach(&m_wndTaskPanel);

    m_pCmcLayout = this->CreateLayout();
    if (m_pCmcLayout->Load(_T("AmitLayout")))
    {
        this->SetLayout(m_pCmcLayout);
    }
    else
    {
        this->GetLayout(m_pCmcLayout);
    }
************
Also in the destructor of my class i am doing this:
    m_pCmcLayout->Save(_T("AmitLayout"));
    delete m_pCmcLayout;

Still i am not able to restore the Taskpanel + Pane with the new size....

What is going wrong here ???

Again you don't need to save pointer to m_pCmcLayout:

to save

CXTPDockingPaneLayout layoutNormal(&m_paneManager);
m_paneManager.GetLayout(&layoutNormal);
layoutNormal.Save(_T("NormalLayout"));

to load:

// Load the previous state for docking panes.
CXTPDockingPaneLayout layoutNormal(&m_paneManager);
if (layoutNormal.Load(_T("NormalLayout")))
{
m_paneManager.SetLayout(&layoutNormal);
}

Thanks. I did is without saving as pointer and it works fine.

However, my taskpanel is getting created by the same size.

since before i load the layout i have a call which is:

m_wndTaskPanel.Create(WS_CHILD|WS_VISIBLE|WS_CLIPSIBLINGS|WS_CLIPCHILDREN, CRect(0, 0, 0, 0), /*this*/ pWnd, 0))

this->CreatePane(ID_PANE, CRect(0, 0, 150, 150), xtpPaneDockLeft);
m_pDocPane->Attach(&m_wndTaskPanel);

so due to this the task panel is always getting set to 150,150.

Issue Resolved.

I was creating the pane each time, when actually i should not have created it once the layout was stored in registry.

FindPane() worked.
