以CSkinEdit( public CEdit )为例:
设置Edit的属性:Multiline, 无Border
1.映射消息:
ON_WM_CTLCOLOR_REFLECT()
HBRUSH CSkinEdit::CtlColor(CDC* pDC, UINT nCtlColor)
{
// TODO: Change any attributes of the DC here
CBitmap bmp;
bmp.LoadBitmap( IDB_BITMAP1 );
m_Brush.Detach();
m_Brush.CreatePatternBrush( &bmp );
pDC->SetBkMode(TRANSPARENT);
return (HBRUSH)m_Brush;
// TODO: Return a non-NULL brush if the parent's handler should not be called
return NULL;
}
m_Brush为CBrush类型的成员变量.
特别注意:
pDC的坐标原点为Edit控件左上角在父窗口的坐标, 所以IDB_BITMAP1左上角对应Edit父窗口的左上角,而不是Edit控件的左上角
2.映射消息:
ON_CONTROL_REFLECT(EN_CHANGE, OnChange)
void CSkinEdit::OnChange()
{
// TODO: If this is a RICHEDIT control, the control will not
// send this notification unless you override the CEdit::OnInitDialog()
// function and call CRichEditCtrl().SetEventMask()
// with the ENM_CHANGE flag ORed into the mask.
// TODO: Add your control notification handler code here
InvalidateRect( NULL );
}
