In one of the articles, I read about the CTitleMenu (http://www.codeproject.com/menu/titlemenu.asp) class that creates a menu with a nice gradient title—that was it! I decided to incorporate some of the code to create a nice static control...and here it is.
Here's how to add this control to your project:
- Copy the GradientStatic.h and GradientStatic.cpp files to your project directory; add those files to your project.
- Put "#include "GradientStatic.h" in files where you plan to use this class.
- Change CStatic definitions to CGradientStatic.
- Use the API described below.
This control is derived from CStatic and adds only a few new functions. Please note that this class is not PERFECT. If you need some other features—just modify it!
By default, CGradientStatic uses the following colors:
- On the left side is a color of the active application's caption (COLOR_ACTIVECAPTION).
- On the right side is a color of the button face (COLOR_BTNFACE).
- The text is painted using a color of the text of the application's caption.
void SetColor(COLORREF cl);
Use this function to change the left color of the gradient. For example:
SetColor(RGB(255,0,0)); //this will set a //RED color. SetColor(GetSysColor(COLOR_ACTIVECAPTION)); //this will use one //of the system- //defined colors
void SetGradientColor(COLORREF cl);
Use this function to change the right gradient color.
void SetTextColor(COLORREF cl);
Use this function to change the text color.
void SetLeftSpacing(int iNoOfPixels);
If the text isn't centered, you can use this function to set a point where CGradientStatic should start painting text. On the default control, leave 10 pixels from the right side.
void SetCenterText(BOOL bCenter = TRUE);
Use this function to center text in the control.
Example of Use
m_pBoldFont = new CFont; //delete it in desctructor m_pBoldFont->CreateFont(25,0,0,0,900,0,0,0,0,0,0, ANTIALIASED_QUALITY,0,"Arial"); //Use big font and standard colors m_cExample.SetFont(m_pBoldFont); m_cExample.SetWindowText("This is CGradientStatic example :)"); //Use font of dialog controls, centered text m_cExample2.SetWindowText("This text is in the center !"); m_cExample.SetFont(m_cOrdinaryButton.GetFont()); //this is a small trick to obtain default font of this dialog m_cExample2.SetColor(RGB(255,0,0)); m_cExample2.SetGradientColor(RGB(0,0,0));
This control has some limitations. They were not a problem for me, so I didn't fix them.
- You have to set the text of the control in run-time (for example, in OnInitdialog()), using the SetWindowText() member function. Text set in resources is ignored.
- If you don't set a font for the control, the default font would be used (yup...this ugly one).
- There is no way to right-align the text right now. That will be easy to fix.

Paolo Adami suggested a small addition to this control. Thanks to the
DrawGradRect(CDC *pDC, CRect r, COLORREF cLeft, COLORREF cRight) function, the control will draw a gradient background also on systems that don't have the msimg32.dll library installed. This code is not such a fancy algorithm as msimg32.dll library and produces a worse effect—but it works fine.
