XWT: Preview & Run-time views are different [message #571697]

Hi,

I have simple UI element, which has two button and a text widgets. The XWT designer and the Preview shows the button and text size (width and height) as I expected. But the run-time widget sizes are not shown as I defined. The default widget size is being shown.

Anyone has any idea, what is the correct way to define the widget width and height?

Demo.xwt
<Composite xmlns="http://www.eclipse.org/xwt/presentation"
xmlns:x="http://www.eclipse.org/xwt" xmlns:c="clr-namespace:demo.xwt"
xmlns:j="clr-namespace:java.lang" x:Class="demo.xwt.Demo">

<Composite.layout>
<GridLayout numColumns="2" />
</Composite.layout>

<Text x:style="SWT.NONE" weight="400" height="150" />

<Button x:style="SWT.PUSH" x:Name="NotifyButton1" text="Notify" width="200" Height="50" />

<Button x:style="SWT.PUSH" x:Name="NotifyButton2" text="Notify" width="200" Height="50" />

</Composite>

Demo.java
public class Demo extends Composite {

public Demo(Composite parent, int style) {
super(parent, style);
}

}

Simple main method:
public static void main(String[] args) {
URL content = Demo.class.getResource("Demo.xwt");
try {
XWT.open(content);
} catch (Exception e) {
e.printStackTrace();
}
}

You should use GridData for GridLayout instead of specifying size directly.
In general Layout manages location and size, so your width/height are overridden.

You want something like this
<Composite xmlns="http://www.eclipse.org/xwt/presentation" xmlns:x="http://www.eclipse.org/xwt">
<Composite.layout>
<GridLayout numColumns="1"/>
</Composite.layout>
<Text x:Style="BORDER">
<Text.layoutData>
<GridData grabExcessHorizontalSpace="true" horizontalAlignment="FILL" heightHint="150"/>
</Text.layoutData>
</Text>
<Button x:Name="NotifyButton1" text="Notify">
<Button.layoutData>
<GridData widthHint="200" heightHint="50"/>
</Button.layoutData>
</Button>
<Button x:Name="NotifyButton2" text="Notify">
<Button.layoutData>
<GridData heightHint="50" widthHint="200"/>
</Button.layoutData>
</Button>
</Composite>

How do you set the width and height, via XWT Visual Designer? If so, it
could be a bug of the tool and please report a bug.
