-<body>
-
-<h2>SWT Example Launcher</h2>
-
-<p>
-The Example Launcher is used to launch SWT examples which can either be Workbench Views,
-or Standalone applications.
-</p>
-
-<ul>
-<li>Workbench Views are examples that are integrated into Eclipse. When the Launcher
-starts a Workbench View, it is opened in the currently active perspective.
-<li>Standalone applications are launched in a separate window.
-</ul>
-
-<h3>Running the Example Launcher</h3>
-
-<p>
-From the Window menu, select Show View --> Other.
-In the Show View dialog, expand SWT Examples and select the SWT Example Launcher view.
-A view containing a list of examples will appear in your current perspective.
-Select an example from the list. A brief description of the example is displayed.
-Click on the Run button to launch the example.
-</p>
-
-
-<h3>Details</h3>
-<p>The example launcher view contains a tree list, a text area, and a button.
-The tree list contains a list of all the SWT examples you can choose
-to run. When an example is selected from the tree, the text area
-displays a short description of the example. The selected example can
-be launched by clicking on the Run button. Standalone examples are run in the
-same thread as the workbench's UI but they are not integrated into the perspective.
-The launcher invokes the <code>open()</code> method of the standalone example.

-The user can insert widgets into a layout and set the values of the layout data
-using a property sheet. When the user has a suitable arrangement, code can be
-generated by clicking on the Code button.
-</p>
-
-<h3>Running the example</h3>
-
-<p>From the Window menu select Show View --> Other.
-In the Show View dialog, expand SWT Examples and select the
-view named SWT Layouts. A view titled SWT Layouts will appear in your current perspective.

-<h2>SWT Example - Paint Tool</h2>
-
-<p>
-This example demonstrates the use of SWT graphics operations in the form of a
-rudimentary bitmap painting program. The Airbrush Tool implementation also
-demonstrates a mechanism for managing timed GUI operations in the background
-that are triggered by user input.
-</p>
-<p>
-Select a tool with which to draw in the drawing area. There are a number of tools
-to choose from on the toolbar. To change the color selection, click on a color in the
-palette below the drawing area: left-click for the foreground color, right-click for the
-background color.
-</p>
-<p>
-Uses SWT's GC and FontDialog, and JFace's InputDialog and action set support.
-</p>
-
-<h3>Running the example</h3>
-
-<p>From the Window menu select Show View --> Other.
-In the Show View dialog, expand SWT Examples and select the
-view named Paint. A view titled Paint will appear in your current perspective.

- <title>SWT - Image Analyzer Example</title>
-</head>
-<body>
-
-<h2>SWT Standalone Example - Image Analyzer</h2>
-
-<p>
-The ImageAnalyzer opens image files and displays the visual contents of the file along with a
-summary of the data in the image file.
-The user can make adjustments to various elements of the image such as scaling and Alpha
-blending and can save these changes to a file.
-</p>
-<p>
-The ImageAnalyzer will load and display image files of type GIF, JPEG, BMP, ICO, and PNG.
-To open a file, use the File --> Open... menu item, and select the image file in the FileDialog.
-If the file is an interlaced GIF or PNG or a progressive JPEG, and Incremental Display is selected,
-then the ImageAnalyzer displays the image increments as they are being loaded.
-If the file contains an animated GIF, then the Next, Previous, and Animate buttons become enabled,
-and they can be used to cycle through the images in the file, or animate them. If a GIF defines a background color,
-as many animated GIFs do, selecting Background will use the GIF's background color.
-If the image has transparency (possible with GIF, PNG, or ICO), then selecting Display Mask will draw the image's transparency
-mask to the right of the image. You can change the background color of the ImageAnalyzer to see the transparency work.
-To turn off the transparency, deselect Display Transparency.
-After an image is loaded, it can be scaled or have alpha transparency applied, using the Scale and Alpha-K combos,
-and the Alpha menu. File --> Reopen restores scaling and Alpha to their default values and reloads the current image file.
-File --> Save As... can be used to save the currently loaded image to another type of image file. If the image has transparency,
-File --> Save Mask As... saves the image's transparency mask.
-</p>
-<p>
-When SWT loads an image file, an instance of org.eclipse.swt.graphics.ImageData is created. (In the case of an ICO file or
-multi-image GIF, an array of ImageData instances is created). The ImageAnalyzer displays all of the data stored in the ImageData
-instance(s) for the currently loaded image file, including the pixel data. Hovering over a pixel in the image display will show the RGB
-color data for that pixel. For certain images (particularly animated GIFs) additional data is stored in the org.eclipse.swt.graphics.ImageLoader
-instance used to load the image. The ImageAnalyzer displays this data as well.

-<h2>SWT Standalone Examples Setup</h2>
-
-<h3>Importing Example Source</h3>
-
-<p>
-*** In the following description, substitute the location in which you installed Eclipse for INSTALLDIR ***
-</p>
-
-<p>Import the example code and all its required resources into your workspace:</p>
-
-<ol>
-<li>Create a Java Project called "SWT Examples".
-<li>Select the project "SWT Examples" in the Packages view.
-<li>Select the File --> Import menu. Select Zip File. Click on Next.
-<li>Locate the source zip file for the SWT examples. For example:
- <ul>
- <li><b>win32: </b><code>INSTALLDIR\eclipse\plugins\org.eclipse.swt.examples_2.0.0\swtexamplessrc.zip</code>
- <li><b>*nix: </b><code>INSTALLDIR/eclipse/plugins/org.eclipse.swt.examples_2.0.0/swtexamplessrc.zip</code>
- </ul>
-<li>Click on Finish.
-<li>Select the File --> Import menu. In the Import dialog, select Zip File. Click on Next.
-<li>Locate the jar file for the SWT examples. For example:
- <ul>
- <li><b>win32: </b><code>INSTALLDIR\eclipse\plugins\org.eclipse.swt.examples_2.0.0\swtexamples.jar</code>
- <li><b>*nix: </b><code>INSTALLDIR/eclipse/plugins/org.eclipse.swt.examples_2.0.0/swtexamples.jar</code>
- </ul>
-<li>Expand the top level directory of the zip file (/). <b>Uncheck "org" and "META-INF"</b>.
-<li>Click on Finish.
-</ol>
-
-<p>Now you need to compile the SWT examples. In order to do this, you must add the SWT jar(s) to
-the compile path:</p>
-<ol>
-<li>Select the project "SWT Examples" in the Packages view and from the pop up menu select Properties.
-<li>Select the Java Build Path item.
-<li>Go to the Libraries tab.
-<li>Click on the Add External JARS... button.
-<li>Locate the swt jar for the platform on which you wish to run:<br>
- <ul>
- <li><b>win32: </b><code>INSTALLDIR\eclipse\plugins\org.eclipse.swt.win32_2.0.0\ws\win32\swt.jar</code>
- <li><b>gtk: </b><code>INSTALLDIR/eclipse/plugins/org.eclipse.swt.gtk_2.0.0/ws/gtk/swt.jar</code>
- <li><b>motif: </b><code>INSTALLDIR/eclipse/plugins/org.eclipse.swt.motif_2.0.0/ws/motif/swt.jar</code>
- <li><b>photon: </b><code>INSTALLDIR/eclipse/plugins/org.eclipse.swt.photon_2.0.0/ws/photon/swt.jar</code>
- <li><b>macosx: </b><code>INSTALLDIR/eclipse/plugins/org.eclipse.swt.carbon_2.0.0/ws/carbon/swt.jar</code>
- </ul>
-<li>Click on OK.
-</ol>
-<p><b>NOTE:</b> For some platforms (such as GTK), more than one jar is required to run SWT (on
-GTK there is a swt.jar and a swt-pi.jar file). In this case, all the required jars must
-be added to the class path. This is done by repeating the steps above for each jar file.
-All jar files are located in the same directory/folder.</p>
-
-<p>At this point your SWT examples should be compiled without any errors. Check the Task
-view for errors. If you get an error like "<code>java.lang.Object</code> not found" it means
-you have not configured a JRE. Go to the Window --> Preferences dialog.
-Select Java --> Installed JREs and ensure that a JRE is installed
-and that the path to the JRE is correct.</p>
-
-<h3><a NAME="Run"></a>Running the Example</h3>
-
-<p>Now you have to configure Eclipse to run the example. This requires putting the SWT
-JNI libraries on the library path so that the VM can find them:
-
-<ol>
-<li>Open the Java Perspective.
-<li>In the Packages view, select the Main class that you want to run.
- For example, the Main class for the Address Book example is
- <code>org.eclipse.swt.examples.addressbook.AddressBook</code>.
-<li>SelectRun --> Run... from the main menu.
-<li>In the Launch Configurations dialog that appears, select Java Application and click
- on the New button.
-<li>Fill in the Name, Project and Main class fields according to the example you wish to run.
-<li>Select the Arguments tab. In the VM Arguements area specify the location of the SWT
- library depending on your target platform as follows:
- <ul>
- <li><b>win32: </b><code>-Djava.library.path=INSTALLDIR\plugins\org.eclipse.swt.win32_2.0.0\os\win32\x86</code>
- <li><b>linux gtk: </b><code>-Djava.library.path=INSTALLDIR/eclipse/plugins/org.eclipse.swt.gtk_2.0.0/os/linux/x86</code>
- <li><b>linux motif: </b><code>-Djava.library.path=INSTALLDIR/eclipse/plugins/org.eclipse.swt.motif_2.0.0/os/linux/x86</code>
- <li><b>solaris motif: </b><code>-Djava.library.path=INSTALLDIR/eclipse/plugins/org.eclipse.swt.motif_2.0.0/os/solaris/sparc</code>
- <li><b>aix motif: </b><code>-Djava.library.path=INSTALLDIR/eclipse/plugins/org.eclipse.swt.motif_2.0.0/os/aix/ppc</code>
- <li><b>hpux motif: </b><code>-Djava.library.path=INSTALLDIR/eclipse/plugins/org.eclipse.swt.motif_2.0.0/os/hpux/PA_RISC</code>
- <li><b>photon qnx: </b><code>-Djava.library.path=INSTALLDIR/eclipse/plugins/org.eclipse.swt.photon_2.0.0/os/qnx/x86</code>
- <li><b>macosx: </b><code>-Djava.library.path=INSTALLDIR/eclipse/plugins/org.eclipse.swt.carbon_2.0.0/os/macosx/ppc</code>
- </ul>
-<li>Click on the Run button.
-</ol>

- This example builds on HelloWorld2 and demonstrates how to resize the Label \
- when the Shell resizes using a Layout.
-
-launchitem.HelloWorld5.name = Hello World (5)
-launchitem.HelloWorld5.description = \
- This example builds on HelloWorld1 and demonstrates how to draw directly on an SWT Control using a graphic context.
-
-launchitem.ImageAnalyzer.name = Image Analyzer
-launchitem.ImageAnalyzer.description = \
- The ImageAnalyzer opens image files and displays the visual contents of the file along with a \
- summary of the data in the image file.\n\n\
- The user can make adjustments to various elements of the image such as scaling and Alpha \
- blending and can save these changes to a file.\n\n\
- The ImageAnalyzer will load and display image files of type GIF, JPEG, BMP, ICO, and PNG. \
- To open a file, use the File->Open... menu item, and select the image file in the FileDialog.\n\n\
- If the file is an interlaced GIF or PNG or a progressive JPEG, and Incremental Display is selected, \
- then the ImageAnalyzer displays the image increments as they are being loaded.\n\n\
- If the file contains an animated GIF, then the Next, Previous, and Animate buttons become enabled, \
- and they can be used to cycle through the images in the file, or animate them. If a GIF defines a background color, \
- as many animated GIFs do, selecting Background will use the GIF's background color.\n\n\
- If the image has transparency (possible with GIF, PNG, or ICO), then selecting Display Mask will draw the image's transparency \
- mask to the right of the image. You can change the background color of the ImageAnalyzer to see the transparency work. \
- To turn off the transparency, deselect Display Transparency.\n\n\
- After an image is loaded, it can be scaled or have alpha transparency applied, using the Scale and Alpha-K combos, \
- and the Alpha menu. File->Reopen restores scaling and Alpha to their default values and reloads the current image file.\n\n\
- File->Save As... can be used to save the currently loaded image to another type of image file. If the image has transparency, \
- File->Save Mask As... saves the image's transparency mask.\n\n\
- When SWT loads an image file, an instance of org.eclipse.swt.graphics.ImageData is created. (In the case of an ICO file or \
- multi-image GIF, an array of ImageData instances is created). The ImageAnalyzer displays all of the data stored in the ImageData \
- instance(s) for the currently loaded image file, including the pixel data. Hovering over a pixel in the image display will show the RGB \
- color data for that pixel. For certain images (particularly animated GIFs) additional data is stored in the org.eclipse.swt.graphics.ImageLoader \
- instance used to load the image. The ImageAnalyzer displays this data as well.
-
-launchitem.JavaViewer.name = Java Syntax Viewer
-launchitem.JavaViewer.description = \
- This example demonstrates how to implement a user-defined line styler for the StyledText widget.\n\n\
- The example provides a typical editor interface. \
- To see the effect of the line styler, open a *.java file. \
- When the contents of the file are displayed in the editor area, notice that the keywords have been highlighted.
-
-launchitem.LayoutExample.name = Layout Example
-launchitem.LayoutExample.description = \
- This example is a simple demonstration of common SWT layouts. \n\n\
- It consists of a tab folder where each tab in the folder allows the \
- user to interact with a different SWT layout. \
- The user can insert widgets into a layout and set the values of the layout data \
- using a property sheet. When the user has a suitable arrangement, code can be \
- generated by clicking on the Code button.
-
-launchitem.TextEditor.name = Text Editor
-launchitem.TextEditor.description = \
- This example demonstrates how to use the StyledText widget to implement \
- a text editor with formatting support.\n\n\
- The example has a typical text editor interface. \
- The Edit menu contains Cut, Copy, Paste and Set Font items and the toolbar \
- provides a bold text toggle, three colour tools that operate on the current \
- selection, and a reset to defaults button that also operates on the current selection.
