CMFCToolBarEditBoxButton::CanBeStretched

Specifies whether a user can stretch the button during customization.

virtual BOOL CanBeStretched() const;

Return Value

This method returns TRUE.

Remarks

By default, the framework does not allow the user to stretch a toolbar button during customization. This method extends the base class implementation ( CMFCToolBarButton::CanBeStretched) by allowing the user to stretch an edit box toolbar button during customization.

CMFCToolBarEditBoxButton::CMFCToolBarEditBoxButton

Constructs a CMFCToolBarEditBoxButton object.

CMFCToolBarEditBoxButton(
    UINT uiID,  
    int iImage,  
    DWORD dwStyle=ES_AUTOHSCROLL,  
    int iWidth=0);

Parameters

[in] uiID
Specifies the control ID.

[in] iImage
Specifies the zero-based index of a toolbar image. The image is located in the CMFCToolBarImages Class object that CMFCToolBar Class class maintains.

[in] dwStyle
Specifies the edit control style.

[in] iWidth
Specifies the width in pixels of the edit control.

Remarks

The default constructor sets the edit control style to the following combination:

WS_CHILD | WS_VISIBLE | ES_AUTOHSCROLL

The default width of the control is 150 pixels.

CMFCToolBarEditBoxButton::CopyFrom

Copies the properties of another toolbar button to the current button.

virtual void CopyFrom(const CMFCToolBarButton& src);

Parameters

[in] src
A reference to the source button from which to copy.

Remarks

Call this method to copy another toolbar button to this toolbar button. src must be of type CMFCToolBarEditBoxButton.

You construct a CMFCToolBarEditBoxButton object in two steps. First call the constructor, and then call CreateEdit, which creates the Windows edit control and attaches it to the CMFCToolBarEditBoxButton object.

CMFCToolBarEditBoxButton::GetByCmd

Retrieves the first CMFCToolBarEditBoxButton object in the application that has the specified command ID.

static CMFCToolBarEditBoxButton* __stdcall GetByCmd(UINT uiCmd);

Parameters

[in] uiCmd
The command ID of the button to retrieve.

Return Value

The first CMFCToolBarEditBoxButton object in the application that has the specified command ID, or NULL if no such object exists.

Remarks

This shared utility method is used by methods such as CMFCToolBarEditBoxButton::SetContentsAll and CMFCToolBarEditBoxButton::GetContentsAll to set or get the text of the first edit box toolbar control that has the specified command ID.

CMFCToolBarEditBoxButton::GetContentsAll

Retrieves the text of the first edit box toolbar control that has the specified command ID.

static CString __stdcall GetContentsAll(UINT uiCmd);

CMFCToolBarEditBoxButton::GetEditBorder

Retrieves the bounding rectangle of the edit part of the edit box button.

virtual void GetEditBorder(CRect& rectBorder);

Parameters

[out] rectBorder
A reference to the CRect object that receives the bounding rectangle.

Remarks

This method retrieves the bounding rectangle of the edit control in client coordinates. It expands the size of the rectangle in each direction by one pixel.

The CMFCVisualManager::OnDrawEditBorder method calls this method when it draws the border around a CMFCToolBarEditBoxButton object.

CMFCToolBarEditBoxButton::GetEditBox

Returns a pointer to the CEdit Class control that is embedded in the button.

CEdit* GetEditBox() const;

Return Value

A pointer to the CEdit Class control that the button contains. It is NULL if the CEdit control has not been created yet.
