Using transparant image button~!

Sample Image - CKbcButton.jpg

Introduction

*I'm not good at English, but if you can understand my story, isn't that enough? Smile | :)

When I made this application, especially as dialog based, a lot of buttons were used. Buttons are very important things in my situation. So I decided to make an Image button source.

As you know, there are many sources for image buttons. I think it's useless work making another image button. But those image buttons have a small problem.

intro - a small problem

In this image, button's background hides the parent's background. That's not what I want. So I am going to handle this problem.

Using the code

There are two ways using this button. First of all, include the following files to your project:

  • KbcBmp.h,
  • KbcBmp.cpp,
  • KbcButton.h,
  • KbcButton.cpp,
  • Picture.h,
  • Picture.cpp

Then, let's start~!

  1. Using DDX_Control
    1. Include "KbcButton.h" in header file.
    2. Declare a CKbcButton variable in header file.
    3. Go to dialog resource and draw a button. Check 'Onwer draw' style.
    4. Use DDX_Control like this in CPP file: DDX_Control(pDX, IDC_PLAYBUTTON, m_btnPlay);
    5. Then set button's image by calling SetButtonImage() function.
      // In your header file
      
      #include "KbcButton.h"
      
      class CTestButtonDlg : public CDialog
      {
      protected:
           CKbcButton  m_btnPlay;
      
          ...
          ...
      }
      
      // in you cpp file
      
      void CTestButtonDlg::DoDataExchange(CDataExchange* pDX)
      {
           CDialog::DoDataExchange(pDX);
           //{{AFX_DATA_MAP(CTestButtonDlg)
           DDX_Control(pDX, IDC_PLAYBUTTON, m_btnPlay);
           //}}AFX_DATA_MAP
      }
      
      
      BOOL CTestButtonDlg::OnInitDialog()
      {
           ...
           ...
      
           // set button image..
           m_btnPlay.SetButtonImage("play.bmp",RGB(255,255,255));
           m_btnPlay.SetToolTipText("Play~!");
           m_btnPlay.SetCursor(AfxGetApp()->LoadCursor(IDC_CURSOR1));
      
           ...
           ...
      }
  2. Using new operation
    1. Include "KbcButton.h" in header file.
    2. Declare a CKbcButton* variable in header file.
    3. Create CKbcButton instance by using new operator.
    4. Call Create() function.
    5. Then set button's image by calling SetButtonImage() function.
      // In your header file
      
      #include "KbcButton.h"
      
      class CTestButtonDlg : public CDialog
      {
      protected:
           CKbcButton*  m_pButton;
      
      
          ...
          ...
      
      // in you cpp file
      
      BOOL CTestButtonDlg::OnInitDialog()
      {
           ...
           ...
      
           // create button and set button image..
           CRect rtButton;
           CWnd* pWnd = GetDlgItem(IDC_STATIC_SHOW);
           pWnd->GetWindowRect(rtButton);
           ScreenToClient(rtButton);
           m_pButton = new CKbcButton;
           m_pButton->Create("CKbcButton", WS_CHILD|WS_VISIBLE|BS_OWNERDRAW, 
                                 rtButton, this, NEWBUTTON);
           m_pButton->SetButtonImage("show.gif",RGB(0,0,255));
      
           ...
           ...
      }

That's all. Isn't it simple?

Make sure that you set 'Owner draw style' to a button.
