A Gradient Static Control

Introduction

The idea was to have a small piece of code which makes it easy to create a gradient control. I saw a lot of great code, but it was not exactly what I want.  So I decided to create my own CGradientStatic-class.

Usage of CGradientStatic

To use this control in your application:

• Design the dialog and add the Static control
• Add the GradientStatic.h header file to your project
• Assign a CGradientStatic to your static control.
• In OnInitDialog(), subclass CGradientStatic control to ID using the SubclassWindow method.

#include "CGradientStatic.h"

//...

class CMainDlg : public CDialogImpl<CMainDlg>
{     
    BEGIN_MSG_MAP(CMainDlg)          
       ...          
       MESSAGE_HANDLER(WM_INITDIALOG, OnInitDialog)          
       REFLECT_NOTIFICATIONS()     
    END_MSG_MAP()
    ...
    LRESULT OnInitDialog(UINT /*uMsg*/, WPARAM /*wParam*/, 
        LPARAM /*lParam*/, BOOL& /*bHandled*/);
    ...
    CGradientStatic m_GradientBar;     
    ...
}; 

//...

LRESULT CMainDlg::OnInitDialog(UINT /*uMsg*/, WPARAM /*wParam*/, 
      LPARAM /*lParam*/, BOOL& /*bHandled*/) 
{
     ...     
     m_GradientBar.SubclassWindow( ::GetDlgItem( IDC_STATIC1 ) );     
     m_GradientBar.SetColor(RGB(255,0,0));
     m_GradientBar.SetGradientColor(RGB(0,0,0));

     ...
}
