3.3 M5 Launch the following snippet. Double click into the text widget until the text disappears. ---------- package org.eclipse.swt.snippets; import org.eclipse.swt.*; import org.eclipse.swt.custom.*; import org.eclipse.swt.events.*; import org.eclipse.swt.layout.*; import org.eclipse.swt.widgets.*; public class SingleLineBug { static StyledText styledText; public static void main(String [] args) { final Display display = new Display(); final Shell shell = new Shell(display); shell.setLayout(new GridLayout()); styledText = new StyledText(shell, SWT.WRAP | SWT.BORDER); styledText.setLayoutData(new GridData(SWT.FILL, SWT.FILL, true, true)); styledText.setText("Rudi "); styledText.addMouseListener(new MouseAdapter() { @Override public void mouseDoubleClick(MouseEvent event) { styledText.append(styledText.getText()); System.out.println(styledText.getCharCount()); } }); shell.setSize(800, 800); shell.open(); while (!shell.isDisposed()) { if (!display.readAndDispatch()) display.sleep(); } display.dispose(); } }
I added "(wrapped)" to the title in case this case is different from the known problems that arise from having an extremely long unwrapped line in StyledText. FH note that using the comment 0 snippet I did not see the text disappear on win2000, at least until character count 655360 was reached.
It happens to me when charcount is 81920 - the OS call that shapes the glyphs (ScriptShape) fails when the text run is that long. It returns E_INVALIDARG result code. The msdn doc does not mention anything about this problem.
closing as wont fix. bug in windows, no workaround available.

In a second thought, the code in shape can detect the run is too big and split it into smaller manageable runs.
