CMFCAutoHideButton::UnSetAutoHideMode

Remarks

On creation, the CMFCAutoHideButton object is attached to a CDockablePane Class. The CDockablePane object is hidden or displayed as the user interacts with the CMFCAutoHideButton object.

By default, the framework automatically creates a CMFCAutoHideButton when the user turns on auto-hide. The framework can create an element of a custom UI class instead of the CMFCAutoHideButton class. To specify which custom UI class the framework should use, set the static member variable CMFCAutoHideBar::m_pAutoHideButtonRTS equal to the custom UI class. By default, this variable is set to CMFCAutoHideButton.

Example

The following example demonstrates how to construct a CMFCAutoHideButton object and use various methods in the CMFCAutoHideButton class. The example shows how to initialize a CMFCAutoHideButton object by using its Create method, show the associated CDockablePane class, and show the auto-hide button.

CMFCAutoHideButton *autoHideButton = new CMFCAutoHideButton();
CDockablePane cPane;
// CMFCAutoHideBar* pParentBar
if (!autoHideButton->Create(pParentBar, &cPane, CBRS_ALIGN_LEFT))
{
   return 0;
}
autoHideButton->ShowAttachedWindow(true);
autoHideButton->ShowButton(true);

CMFCAutoHideButton::BringToTop

void BringToTop();

Remarks

CMFCAutoHideButton::Create

Creates and initializes an auto-hide button.

virtual BOOL Create(
    CMFCAutoHideBar* pParentBar,
    CDockablePane* pAutoHideWnd,
    DWORD dwAlignment);

Parameters

pParentBar
[in] A pointer to the parent toolbar.

pAutoHideWnd
[in] A pointer to a CDockablePane object. This auto-hide button hides and shows that CDockablePane.

dwAlignment
[in] A value that specifies the alignment of the button with the main frame window.

Return Value

Nonzero if successful; otherwise 0.

Remarks

When you create a CMFCAutoHideButton object, you must associate the auto-hide button with a specific CDockablePane. The user can use the auto-hide button to hide and show the associated CDockablePane.

The dwAlignment parameter indicates where the auto-hide button resides in the application. The parameter can be any one of the following values:

  • CBRS_ALIGN_LEFT

  • CBRS_ALIGN_RIGHT

  • CBRS_ALIGN_TOP

  • CBRS_ALIGN_BOTTOM

CMFCAutoHideButton::GetAlignment

Retrieves the alignment of the auto-hide button.

DWORD GetAlignment() const;

Return Value

A DWORD value that contains the current alignment of the auto-hide button.

Remarks

The alignment of the auto-hide button indicates where the button resides on the application. It can be any one of the following values:

  • CBRS_ALIGN_LEFT

  • CBRS_ALIGN_RIGHT

  • CRBS_ALIGN_TOP

  • CBRS_ALIGN_BOTTOM

CMFCAutoHideButton::GetAutoHideWindow

Returns the CDockablePane object associated with the auto-hide button.

CDockablePane* GetAutoHideWindow() const;

Return Value

A pointer to the associated CDockablePane object.

Remarks

To associate an auto-hide button with a CDockablePane, pass the CDockablePane as a parameter to the CMFCAutoHideButton::Create method.

CMFCAutoHideButton::GetParentToolBar

CMFCAutoHideBar* GetParentToolBar();

Return Value

Remarks

CMFCAutoHideButton::GetRect

CRect GetRect() const;

Return Value

Remarks

CMFCAutoHideButton::GetSize

Determines the size of the auto-hide button.

CSize GetSize() const;

Return Value

A CSize object that contains the button size.

Remarks

The calculated size includes the size of the border of the auto-hide button.

CMFCAutoHideButton::GetTextSize

Returns the size of the text label for the auto-hide button.

virtual CSize GetTextSize() const;

Return Value

A CSize object that contains the size of the text for the auto-hide button.

CMFCAutoHideButton::IsActive

Indicates whether the auto-hide button is active.

BOOL IsActive() const;

TRUE if the auto-hide button is active; FALSE otherwise.

Remarks

An auto-hide button is active when the associated CDockablePane Class window is shown.

CMFCAutoHideButton::IsHorizontal

Determines whether the auto-hide button is horizontal or vertical.

BOOL IsHorizontal() const;

Return Value

Nonzero if the button is horizontal; 0 otherwise.

Remarks
