Hi,
I'm implementing an Wizard Page extending the class WizardPage. In the
createControl method I have the following code:
public void createControl(Composite parent) {
Composite composite1 = createComposite(parent,2);
new Label(composite1,SWT.NULL).setText("class name:");
className = createTextField(composite1);
className.addModifyListener(new TextModifyListener());
textChanged();
Composite composite2 = createComposite(parent,1);
composite2.setVisible(true);
new EiffelContainerSelectionGroup(composite2,null);
setControl(parent);
}
the problem is: the second composite is not showing up inside the Wizard
Page - only the first one.
the createComposite method looks as follows:
private Composite createComposite(Composite parent, int columns){
Composite composite = new Composite(parent,SWT.NULL);
GridLayout layout = new GridLayout();
layout.numColumns = columns;
composite.setLayout(layout);
GridData data = new GridData();
data.horizontalAlignment=SWT.FILL;
data.grabExcessHorizontalSpace=true;
//data.verticalAlignment=SWT.FILL;
composite.setLayoutData(data);
return composite;
}
Does anyone know, where the problem is? I've tried to put the two
composites inside a top-level composite and with that both composites
appeared but the result didn't look like I expected it to do. Although I
specified only one column for the top Level composite, all widgets were on
the left side of the page...
Kind regards, Kathi

Yes, that was the initial problem: I have to create only one control and
pass it to the parent. Evertything else should be inside this new top
level control.
thanks for your help

it's me again,
I tried to modify the GridData a bit and now it works with the extra
top-Level Composite.
But it shouldn't it work without this extra composite, too?
regards, Kathi

You problem has more chances of getting resolved at SWT newsgroup eclipse.platform.swt
Am not SWT guru, but it looks like you were facing this issue either due to incorrect spanning (hspan) or incorrect nesting of composites. Like I said - i don't know for sure.
Ankur..
