SECOwnerDrawButton Class

class SECOwnerDrawButton: public CButton

The SECOwnerDrawButton class is an abstract base class. SECOwnerDrawButton provides the basic functionality required for implementing an owner draw push button. You can create your own owner draw button objects simply by deriving a class from SECOwnerDrawButton and overriding the pure virtual functions DrawFocus and DrawSpecific.

When the user clicks the button, the control's OnBnClicked method is called (as well as the standard BN_CLICKED notification that is sent to its parent).

See the COLOR sample in the \\OT\\SAMPLES\\STANDARD\\CONTROLS\\COLRWELL directory for a demonstration of this class.

Defined in: SECBTNS.h

Example

You can attach classes derived from SECOwnerDrawButton to existing push buttons with

m_OwnerDrawButton.AttachButton(IDC_BUTTON1, this);

You can dynamically create an SECOwnerDrawButton button control with

m_OwnerDrawButton.Create(NULL, WS_VISIBLE | WS_TABSTOP
                          | WS_CHILD, rect, this, IDC_BUTTON1);
