Hi all
I'm quite new to the visual editor.
I'm trying now to create a new property sheet editor. Since I'm not fond
of writing GUI code by hand (I hate it in fact), I tried creating the
editor using the VE, without success up to now.
I'm quite sure its because I'm missing some important part...
Anybody can supply a pointer?
thx
Eric.

Hi again.
I tried just that.
Also tried using the constants:
SWT.NONE and SWT.EMBEDDED, no use. I only get an empty dialog with ok and
cancel buttons in it.
Playing with composites like this is exactly what I am looking for. What
am I doing wrong..?
I created a composite using VE with a 2 labels and a text area. This is to
be used as a propertySheet editor. So, i have derived a class from
jface.dialogs.Dialog. In this class, i have the method:
I can't find the void method but ther is this one:
protected Control createDialogArea(Composite parent)
{
MyTestComposite comp = new MyTestComposite(parent,SWT.NULL);
return comp;
}
I can also see the createContents method but the doc discourages using it.
Anyway, no matter which I use, I always get my empty dialog.
I open the dialog from the PropertyDescriptor using this code:
result = new ExtendedDialogCellEditor(composite, getLabelProvider())
{
protected Object openDialogBox(Control cellEditorWindow)
{
TestDialog2 dialog = new TestDialog2(cellEditorWindow.getShell());
dialog.open();
return "whatever";
}
};
Sorry for the bother, but many thx for the help.
Eric.

I'm sorry it's taken so long to get back to you. I've had one thing
after another come up, the last being a reinstall of my whole
computer... :-}
I think you're missing a layout manager on the parent. Try inserting:
parent.setLayout(new FillLayout());
before the line that creates your test Composite. Please write back if
this doesn't work.

I suggest using VE to create a new SWT control that subclasses
Composite. Then your property sheet editor only needs to instantiate
your new control and use it. You eliminate 95%+ of manual coding that way.

Hi David
I've done this, I've created a new Composite using the Visual Editor.
Now, How can I connect this composite to a dialog that will be the editor
that will be launched from the property sheet?
My composite class cannot be used as it is can't it? I'm missing the part
where I can link what I create using the VE with the dialog object.
thx for the help!
Eric.

Your dialog object has a createControl() method for creating its UI.
Just put one line in there:
public void createControl(Composite parent) {
new MyComposite(parent, SWT.NULL);
}
(of course, substitute your composite class for MyComposite...)

This code works fine for me:
public class TestDialog extends Dialog {
/**
* @param parentShell
*/
public TestDialog(Shell parentShell) {
super(parentShell);
}
/* (non-Javadoc)
* @see
org.eclipse.jface.dialogs.Dialog#createDialogArea(org.eclips e.swt.widgets.Composite)
*/
protected Control createDialogArea(Composite parent) {
parent.setLayout(new FillLayout());
return new MyDialogContents(parent, SWT.NULL);
}
}

Dave Orme
