Sample Image Sample Image Sample Image

Abstract

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

Main CCeButtonST features are:

  • Standard CButton properties
  • Text and icon on the same button
  • Only text or only icon buttons
  • Support for any size icons (max. 256 colors)
  • 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 dynamically created
  • Each button can have its own mouse pointer
  • Button is highlighted also when the window is inactive, like happens in Internet Explorer
  • Built-in basic support for menus
  • Can be derived to create other button styles not supplied by default
  • Full source code included!
  • UNICODE compatible
  • Windows CE v3.0 compatible
  • Cost-less implementation in existing applications

How to integrate CCeButtonST in your application

In your project include the following files:

  • CeBtnST.h
  • CeBtnST.cpp

Create a CCeButtonST 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:

CCeButtonST m_btnOk;
Now attach the button to CCeButtonST. 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 CCeButtonST object dynamically

In your application, create a member variable for the button. Please note that this variable is a pointer:

CCeButtonST* 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 CCeButtonST;
m_pbtnOk->Create(_T("&Ok"), WS_CHILD | WS_VISIBLE | WS_GROUP | WS_TABSTOP, 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;

History

  • v1.2 (18/December/2001)
    Corrected a CE bug in OnLButtonDown
  • v1.1 (28/November/2001)
    Corrected the "DestroyCursor" problem
  • v1.0 (22/October/2001)
    First release

Remarks

The demo application shows nearly all the features of the CCeButtonST class.
It includes project settings for all the emulators included in Visual C++ eMbedded Tools v3.0 plus
settings to compile and run on the Advantech PCM-4823 single board computer.
CCeButtonST 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 CCeButtonST demo application.

If you change only the icons you get memory leaks in 4k size
(tested on WCE 4.2 and Microsoft Visual c++ 4.0 compiler).
