Abstract

CButtonST is a class derived from MFC CButton class.
With this class your applications can have standard buttons or new and modern buttons with "flat" style!

Main CButtonST features are:

  • Standard CButton properties
  • Text and icon (or bitmap) on the same button
  • Only text or only icon/bitmap buttons
  • Support for any size icons (max. 256 colors)
  • Support for bitmaps
  • Support for transparent buttons (for bitmapped applications)
  • Standard or flat button style
  • Change runtime from flat to standard style
  • Buttons can have two images. One when the mouse is over the button and one when the mouse is outside (only for "flat" buttons)
  • Every color can be customized
  • Can be used via DDX_ calls
  • Can be used in DLLs
  • Can be dinamically created
  • Each button can have its own mouse pointer
  • Button is hilighted also when the window is inactive, like happens in Internet Explorer
  • Built-in support for multiline tooltips
  • Built-in basic support for menus
  • Built-in support for owner draw menus (using BCMenu class)
  • Built-in basic support for sounds
  • Can be derived to create other button styles not supplied by default
  • Full source code included!
  • UNICODE compatible
  • Cost-less implementation in existing applications

How to integrate CButtonST in your application

In your project include the following files:

  • BtnST.h
  • BtnST.cpp
Starting from version 3.5, CButtonST now supports menus created using the BCMenu class.
This 3rd party class gives you the ability to show menus using the most recent visual styles as seen
on the latest Microsoft products or even in Windows XP.
Latest BCMenu version can be found here.

To enable support for BCMenu the following two lines in BtnST.h must be enabled:
#define	BTNST_USE_BCMENU
#include "BCMenu.h"
Also, the following files must be included in your project:
  • BCMenu.h
  • BCMenu.cpp
Note: please note that when BCMenu support is enabled the parameters accepted by the SetMenu method are different!

Starting from version 3.6, CButtonST can play sounds on particular button states.

To enable support for sound the following line in BtnST.h must be enabled:
#define	BTNST_USE_SOUND
This gives access to the SetSound method.

Create a CButtonST object statically
With dialog editor create a standard button called, for example, IDOK (you don't need to make it owner drawn) and create a member variable for this button:
CButtonST m_btnOk;
Now attach the button to CButtonST. For dialog-based applications, in your OnInitDialog:
// Call the base-class method
CDialog::OnInitDialog();

// Create the IDOK button
m_btnOk.SubclassDlgItem(IDOK, this);
Or in your DoDataExchange:
// Call the base method
CDialog::DoDataExchange(pDX);

// Create the IDOK button
DDX_Control(pDX, IDOK, m_btnOk);
Create a CButtonST object dynamically
In your application, create a member variable for the button. Please note that this variable is a pointer:
CButtonST* m_pbtnOk;
Now create the button. For dialog-based applications, in your OnInitDialog:
// Call the base-class method
CDialog::OnInitDialog();

// Create the IDOK button
m_pbtnOk = new CButtonST;
m_pbtnOk->Create(_T("&Ok"), WS_CHILD | WS_VISIBLE | WS_GROUP | WS_TABSTOP, <BR>                CRect(10, 10, 200, 100), this, IDOK);
// Set the same font of the application
m_pbtnOk->SetFont(GetFont());
Remember to destroy the button or you will get a memory leak. This can be done, for example, in your class destructor:
if (m_pbtnOk) delete m_pbtnOk;

DWORD SetMenuCallback(HWND hWnd, UINT nMessage, LPARAM lParam = 0)
SizeToContent
Resizes the button to the same size of the image.
To get good results both the IN and OUT images should have the same size.
void SizeToContent()
SetSound
Sets the sound that must be played on particular button states.
This method is available only if BTNST_USE_SOUND is defined.
// Parameters:
//     [IN]   lpszSound
//            A string that specifies the sound to play.
//            If hMod is NULL this string is interpreted as a filename, <BR>//            else it is interpreted as a resource identifier.
//            Pass NULL to remove any previously specified sound.
//     [IN]   hMod
//            Handle to the executable file that contains the resource to <BR>//            be loaded.
//            This parameter must be NULL unless lpszSound specifies a <BR>//            resource identifier.
//     [IN]   bPlayOnClick
//            TRUE if the sound must be played when the button is clicked.
//            FALSE if the sound must be played when the mouse is moved over <BR>//            the button.
//     [IN]   bPlayAsync
//            TRUE if the sound must be played asynchronously.
//            FALSE if the sound must be played synchronously. The <BR>//            application takes control after the sound is completely played.
//
// Return value:
//     BTNST_OK
//        Function executed successfully.
//
DWORD SetSound(LPCTSTR lpszSound, 
               HMODULE hMod = NULL,

               BOOL bPlayAsync = TRUE)
OnDrawBackground
This function is called every time the button background needs to be painted.
If the button is in transparent mode this function will NOT be called.
This is a virtual function that can be rewritten in CButtonST-derived classes
to produce a whole range of buttons not available by default.
// Parameters:
//     [IN]   pDC
//            Pointer to a CDC object that indicates the device context.
//     [IN]   pRect
//            Pointer to a CRect object that indicates the bounds of the
//            area to be painted.
//
// Return value:
//     BTNST_OK
//        Function executed successfully.
//
virtual DWORD OnDrawBackground(CDC* pDC, CRect* pRect)
OnDrawBorder
This function is called every time the button border needs to be painted.
This is a virtual function that can be rewritten in CButtonST-derived classes
to produce a whole range of buttons not available by default.
// Parameters:
//     [IN]   pDC

//     [IN]   pRect
//            Pointer to a CRect object that indicates the bounds of the
//            area to be painted.
//
// Return value:
//     BTNST_OK
//        Function executed successfully.
//
virtual DWORD OnDrawBorder(CDC* pDC, CRect* pRect)
GetVersionI
Returns the class version as a short value.
// Return value:
//     Class version. Divide by 10 to get actual version.
//
static short GetVersionI()
GetVersionC
Returns the class version as a string value.
// Return value:
//     Pointer to a null-terminated string containig the class version.
//
static LPCTSTR GetVersionC()

Remarks

The demo application shows nearly all the features of the CButtonST class.
CButtonST architecture makes possible to produce a whole range of buttons not available by default. If someone implements new button styles I will be happy to include his code in the next CButtonST demo application.

Thanks

Thanks very much to the dozens of users that are using CButtonST in their applications.
Thanks also to all the people that finds and fixes bugs. Thanks!
If possible, please send a screenshot of your application where CButtonST is used. These screenshots will be collected for personal interest.
