Hi,

I would like to know if it's possible to hide some text who are
displayed inside a StructureTextEditor.

For example I've the following text inside the editor at the beginin

<?xml version=\"1.0\" encoding=\"UTF-8\"?>
<!DOCTYPE xgui:module PUBLIC \"-TOTO-\" \"unknown.dtd\">

and I don't want to display it

(I want to have the code completion enabled)

Thanks

Alexandre

Do I need to play with the ProjectionViewer setVisibleRegion ? If yes
how to work with ProjectionViewer and where to call this function ?

Thanks

Alexandre

I've tryed the following code without success could someone point me
what's wrong

public void activateEditor() {
String str = "<?xml version=\"1.0\" encoding=\"UTF-8\"?><!DOCTYPE
xgui:module PUBLIC \"-TOTO-\" \"unknown.dtd\"";

boolean readOnly = true;
if (property != null) {
String v = property.getValue();
str = v == null ? "" : v;
readOnly = false;
}

// Update the contents of the InputStreamEditorInput
InputStreamEditorInput input = (InputStreamEditorInput) getEditorInput();
InputStream is = new ByteArrayInputStream(str.getBytes());
input.setContents(is);
input.setReadOnly(readOnly);
getSourceViewer().setVisibleRegion(str.length(),
getSourceViewer().getDocument().getLength());
// Finally update the user-interface
setInput(getEditorInput());
}

Hi,

Look for an article on code/text folding on Eclipse.org.
