Remarks

CDockablePane implements the following functionality:

Docking a pane to a main frame window.
Switching a pane to auto-hide mode.
Attaching a pane to a tabbed window.
Floating a pane in a miniframe window.
Docking a pane to another pane that is floating in a miniframe window.
Resizing a pane.
Loading and saving state for a docking pane.

Note

State information is saved to the Windows registry.
Creating a pane with or without a caption. The caption can have a text label and it can be filled with a gradient color.
Dragging a pane while displaying the contents of the pane
Dragging a pane while displaying a drag rectangle.

To use a docking pane in your application, derive your pane class from the CDockablePane class. Either embed the derived object into the main frame window object or into a window object that controls the instance of your pane. Then call the CDockablePane::Create method or the CDockablePane::CreateEx method when you process the WM_CREATE message in the main frame window. Finally, set up the pane object by calling CBasePane::EnableDocking, CBasePane::DockPane, or CDockablePane::AttachToTabWnd.

Customization Tips

The following tips apply to CDockablePane objects:

If you call CDockablePane::AttachToTabWnd for two non-tabbed, dockable panes, a pointer to a tabbed window will be returned in the ppTabbedControlBar parameter. You can continue to add tabs to the tabbed window by using this parameter.
The kind of tabbed pane that is created by CDockablePane::AttachToTabWnd is determined by the CDockablePane object in the pTabControlBarAttachTo parameter. You can call CDockablePane::SetTabbedPaneRTC to set the kind of tabbed pane that the CDockablePane will create. The default type is determined by the dwTabbedStyle of CDockablePane::Create when you first create the CDockablePane. If dwTabbedStyle is AFX_CBRS_OUTLOOK_TABS the default type is CMFCOutlookBar Class; if dwTabbedStyle is AFX_CBRS_REGULAR_TABS the default type is CTabbedPane Class.
If you want to dock one dockable pane to another, call the CDockablePane::DockToWindow method. The original pane must be docked somewhere before you call this method.
The member variable CDockablePane::m_bHideInAutoHideMode controls how dockable panes behave in auto hide mode when you call CDockablePane::ShowPane. If this member variable is set to TRUE, dockable panes and their auto hide buttons will be hidden. Otherwise, they will slide in and out.
You can disable auto-hide animation by setting the CDockablePane::m_bDisableAnimation member variable to TRUE.

Example

The following example demonstrates how to configure a CDockablePane object by using various methods in the CDockablePane class. The example illustrates how to enable the auto-hide all feature for the dockable pane, enable the caption or the gripper, enable the auto-hide mode, show the pane, and animate a pane that is in auto-hide mode. This code snippet is part of the Visual Studio Demo sample.

// GetOwner is an inherited method.
    CDockablePane* pParentBar = DYNAMIC_DOWNCAST(CDockablePane, GetOwner());


...


        pParentBar->EnableAutohideAll();
        pParentBar->EnableGripper(true);
        pParentBar->SetAutoHideMode(true, CBRS_ALIGN_LEFT);
        pParentBar->ShowPane(true,false,true);
        pParentBar->Slide(true);
