Hyperlink wrapping in ScrolledForm [message #462806] Wed, 19 October 2005 20:54 Go to next message

Hi all,

I can't get wrapping working for a Hyperlink in a ScrolledForm. I some
cases can get the links to show, but either 1) the horizontal scroll
appears, or 2) no scroll, but the links are chopped at the Form border.

What I'm looking for is no H_SCROLL and V_SCROLL as necessary.

Anyone have any experience with this?

Thanks,
Todd


Below is my test code (chopping example):

public class HyperlinkTester {

public HyperlinkTester() {
super();
}

/**
* @param args
*/
public static void main(String[] args) {
Display display = new Display();

Shell shell = new Shell(display);
shell.setLayout(new FillLayout());

FormToolkit toolkit = new FormToolkit(display);
ScrolledForm form = new ScrolledForm(shell, SWT.V_SCROLL);
form.setExpandHorizontal(true);
form.setExpandVertical(true);
// form.setBackground(colors.getBackground());
// form.setForeground(colors.getColor(FormColors.TITLE));
// form.setFont(JFaceResources.getHeaderFont());
// final ScrolledForm form = toolkit.createScrolledForm(shell);

for (int i = 0; i <= 4; i++) {
Composite c = toolkit.createComposite(form);
final Hyperlink href = new Hyperlink(form.getBody(), SWT.WRAP);
href
.setText("Could anyone please help me out in how to provide a
hyperlink text using SWT. I got an example but its using html in SWT,
and not working with other tools of SWT. Please could anyone help me out
with an example including ");
// href.setForeground(new Color(null, 0, 0, 255));
href.setFocus();
href.setUnderlined(true);

// TableWrapData twd = new TableWrapData();
// twd.
// href.setLayoutData();
}
TableWrapLayout layout = new TableWrapLayout();
layout.bottomMargin = 12;
layout.topMargin = 12;
layout.leftMargin = 12;
layout.rightMargin = 12;
layout.verticalSpacing = 5;
layout.numColumns = 1;
layout.makeColumnsEqualWidth = false;
// RowLayout layout = new RowLayout(SWT.HORIZONTAL);
// layout.wrap = true;
form.getBody().setLayout(layout);

form.setExpandVertical(true);
form.setExpandHorizontal(true);
shell.setSize(350, 200);
shell.open();
while (!shell.isDisposed()) {
if (!display.readAndDispatch()) {
display.sleep();
}
}
display.dispose();
}

}

I've run into this problem as well. Hyperlinks don't seem to wrap in any
form, whether it is a ScrolledForm or not. Here are two simplified
snippets showing hyperlinks wrapping succesfully directly on the shell,
and hyperlinks not wrapping on a form.

Sorry for the "me too" post, but I wanted to clarify that this problem
occurs even when you use the toolkit methods to create the form and
hyperlink.

Thanks for the sanity check. I've been wringing it every which way for
a couple days with no success. Were you able to "fake" wrapping
hyperlinks with FormText or Label?

No problem. I filed a bug report, as that's probably the best way to
proceed. The bug is https://bugs.eclipse.org/bugs/show_bug.cgi?id=113382.

> Were you able to "fake" wrapping hyperlinks with FormText or Label?

No, but that's a great idea. I'll try it as a short-term fix.

Thanks,
