Remarks

Other types of buttons are derived from the CMFCButton class, such as the CMFCURLLinkButton class, which supports hyperlinks, and the CMFCColorButton class, which supports a color picker dialog box.

The style of a CMFCButton object can be 3D, flat, semi-flat or no border. Button text can be aligned at the left, top, or center of a button. At run time, you can control whether the button displays text, an image, or text and an image. You can also specify that a particular cursor image be displayed when the cursor hovers over a button.

Create a button control either directly in your code, or by using the MFC Class Wizard tool and a dialog box template. If you create a button control directly, add a CMFCButton variable to your application, and then call the constructor and Create methods of the CMFCButton object. If you use the MFC Class Wizard, add a CButton variable to your application, and then change the type of the variable from CButton to CMFCButton.

To handle notification messages in a dialog box application, add a message map entry and an event handler for each notification. The notifications sent by a CMFCButton object are the same as those sent by a CButton object.

Example

The following example demonstrates how to configure the properties of the button by using various methods in the CMFCButton class. The example is part of the New Controls sample.

CMFCButton m_Button;

// int m_iImage
// IDB_BTN1_32, IDB_BTN1_HOT_32, IDB_BTN1, IDB_BTN1_HOT are int macros that are #define.
if (m_iImage == 1)
{
   m_Button.SetImage((HBITMAP)NULL);
}
else
{
   m_Button.SetImage(IDB_BTN1_32, IDB_BTN1_HOT_32);
}

// int m_iImage
if (m_iImage == 0)
{
   m_Button.SetWindowText(_T(""));
}
else
{
   m_Button.SetWindowText(_T("Button"));
}

// Resize the button.
m_Button.SizeToContent();
m_Button.EnableFullTextTooltip(true);
// Use the application menu font at the button text font.
m_Button.EnableMenuFont();
// Use the current Windows theme to draw the button borders.
m_Button.EnableWindowsTheming(true);
// Set the button to auto-repeat mode.
m_Button.SetAutorepeatMode();
// Set the background color for the button text.
m_Button.SetFaceColor(RGB(255,0,0),true);
m_Button.SetTextColor(RGB(0,0,255));
// Set the tooltip of the button.
m_Button.SetTooltip(_T("this is a button!"));
