HTML Editor with Java and And webkit
i want to add WYSIWYG HTML editor to my Java program.
my idea is to do Something like this but not with python - with Java.
i know about couple of options and their problems :
Anyway, I just prefer not to use it because Gecko is slower then webkit.
That's way I chose to work with Browser Object from org.eclipse.swt.browser Package.
For now, I have the code below:
The code, first create a instance of the browser object.
After this it's load HTML page with contenteditable='true' attributes on the body tag.
If its load a page its supposed to add contenteditable='true' attributes to the body tag, and when its save the page it's supposed remove it.
My questions are:
Or, in general :
I already check the SWT Snippets - doesn't help much.
Thanks a lot.
import org.eclipse.swt.SWT;
import org.eclipse.swt.SWTError;
import org.eclipse.swt.browser.Browser;
import org.eclipse.swt.layout.FillLayout;
import org.eclipse.swt.widgets.Composite;
import org.eclipse.swt.widgets.Display;
import org.eclipse.swt.widgets.Shell;
public class editor {
public static void main(String [] args) {
String html = "<html><title>Editor</title>"
+ "<body contenteditable='true'>"
+ " <h2>All the Page is ditable!!!!!</h2>"
+ "<p>Heres a typical paragraph element</p>"
+ "<ol><li>and now a list</li>"
+ "<li>with only</li>"
+ "<li>three items</li>"
+ "</ol></body></html>";
Display display = new Display();
Shell shell = new Shell(display);
shell.setLayout(new FillLayout());
final Browser browser;
try {
browser = new Browser(shell, SWT.BORDER);
}
catch (SWTError e) {
System.out.println(e.getMessage());
display.dispose();
return;
}
Composite comp = new Composite(shell, SWT.NONE);
comp.setLayout(new FillLayout(SWT.ALL));
browser.setText(html);
shell.open();
while (!shell.isDisposed()) {
if (!display.readAndDispatch())
display.sleep();
}
display.dispose();
}
}
DJ Native Swing项目有几个HTML编辑器，使用SWT浏览器实现（这是一个实现细节）：http://djproject.sourceforge.net/ns
I like it that you asked some very specific questions! Good job brainstorming before you get your hands dirty.
Fortunately, there's a fairly generic solution to your problem: just run JavaScript in the browser.
For instance:
Browser browser = new Browser(parent, SWT.NONE);
// Just to be sure we can use JavaScript
browser.setJavascriptEnabled(true);
boolean result = browser.execute("alert('Hello SWT!')");
if (result) {
System.out.println("script executed");
} else {
System.err.println("script failed to execute");
}
Of course you might want to send data from the browser back to SWT; in this case you might end up in the worst case having to parse browser.getText() . I'm not sure if there's a better way of doing this.
你的这一个tinymc：http://tinymce.moxiecode.com/它有很好的文档，你可以将它集成到几乎任何现有的代码，因为它有一个很好的界面和大量的插件。
