Using Swing Components In the previous chapter, we discussed a number of concepts, including how Java’s user interface facility is put together and how the larger pieces work. Selection from Learning Java Book. The following XSL examples are for picture button controls, as specified in.section 2.3.2.10 The following is an example of a picture button control with conditional formatting. The src attribute is set to image img1.jpg. This means that the picture button displays image img1.jpg contained in the form template.

A PictureButton displays a picture and, like a CommandButton,is used to carry out an action. For example, you can use a buttonwith a picture of a file to save a file, or a button with a pictureof a stop sign to cancel a requested deletion.

The picture image can be in the following formats:

• Bitmaps, with .BMP or .RLE extensions

• Windows metafiles, with the .WMF extension

• GIF or animated GIF files, with the .GIF extension

• JPEG files, with .JPEG or .JPG extensions

Introduction

CCustomBitmapButton is MFC control derived from the CWnd class. The button has two parts: a background and a foreground. If the operating system is WinXP and XP Themes are enabled the background is a bitmap loaded from the current active theme resource file (I use similar technique to draw the scroll buttons in the CCustomTabCtrl control); otherwise, the 'DrawFrameControl' function is used to draw the button background. The foreground is a user-defined monochrome bitmap (glyph) drawn transparently on the button background.

Supported features:

• Standard or XP Themes view

• 12 predefined background styles

• User-defined foregrounds (bitmap glyphs)

• Button states supported: 'NORMAL','HOT','PRESSED', and 'DISABLED'

• Buttons can be created in the caption bar area

• Dialog, SDI and MDI support for the caption buttons

• Ficker-free drawing

• Built-in tooltips

Using the Code

To integrate the CCustomBitmapButton class into your application as a caption frame, please follow the steps below:

1. Add ThemeUtil.h, ThemeUtil.cpp, CustomBitmapButton.h, CustomBitmapButton.cpp, Tmschema.h, and Schemadef.h to your project.

2. Include CustomBitmapButton.h to the appropriate header file—usually the dialog class header where the CCustomBitmapButton class is used.

3. Declare m_ctrlCaptionFrame object of type CCustomBitmapButton in your dialog header.

4. Create the caption frame.

   In your dialog's OnInitDialog, add the following code:

5. After creating the caption frame, add as many buttons as you need.

   To add caption buttons, call AddCaptionButton in your dialog's OnInitDialog:

6. Process WM_NOTIFY messages from the caption buttons in your dialog class. As users click a button, the button sends notification messages (NM_CLICK, NM_RCLICK, NM_DBLCLK, and NM_RDBLCLK) to its parent window. Handle these messages if you want to do something in response.

7. Don't forget to destroy the caption frame; otherwise, you will have memory leaks.
