Hello,
I have a XWT file UI description, containing a button btn1. It's a simple example of my aim.
<Composite xmlns="http://www.eclipse.org/xwt/presentation"
xmlns:x="http://www.eclipse.org/xwt" xmlns:css="http://www.eclipse.org/css"
xmlns:c="clr-namespace:myproject.ui" xmlns:j="clr-namespace:myproject.ui"
x:Class="myproject.ui.Essai" >
<Composite.layout>
<GridLayout numColumns="2" />
</Composite.layout>
<Composite.layoutData>
<GridData grabExcessHorizontalSpace="true"
horizontalAlignment="SWT.FILL" />
</Composite.layoutData>
<Label text="Name" css:id="LabelUnBold"></Label>
<Text name="name"
text="{Binding path=name, updateSourceTrigger=PropertyChanged}">
<Text.layoutData>
<GridData grabExcessHorizontalSpace="true" widthHint="150"
horizontalIndent="40" />
</Text.layoutData>
</Text>
<Button name="btn" text="btn1" selectionEvent="changeFirstNamet"></Button>
<Button name="btn" text="btn2"></Button>
<Label text="Firstname" css:id="LabelUnBold"></Label>
<Text name="firstName"
text="{Binding path=firstName, updateSourceTrigger=PropertyChanged}">
<Text.layoutData>
<GridData grabExcessHorizontalSpace="true" widthHint="150"
horizontalIndent="40" />
</Text.layoutData>
</Text>
<Label text="Namet" css:id="LabelUnBold"></Label>
<Text name="namet" text="{Binding path=name}">
<Text.layoutData>
<GridData grabExcessHorizontalSpace="true" widthHint="150"
horizontalIndent="40" />
</Text.layoutData>
</Text>
<Label text="Firstnamet" css:id="LabelUnBold"></Label>
<Text name="firstNamet" text="{Binding path=firstName,updateSourceTrigger=PropertyChanged}">
<Text.layoutData>
<GridData grabExcessHorizontalSpace="true" widthHint="150"
horizontalIndent="40" />
</Text.layoutData>
</Text>
</Composite>
On clicking on th button btn1, an event is called in the java class in order to change a value of the datacontext.
public class Essai extends Composite{
/**
* @param _parent
* @param _style
*/
public Essai(Composite _parent, int _style) {
super(_parent, _style);
}
public void changeFirstNamet(Event _event){
Person data = (Person)XWT.getDataContext(this);
data.setFirstName("hello");
}
}
On clicking on the btn1 button, this value (hello) must be displayed in the firstNamet widget (and firstName too) in the xwt file (a Text). But it doesn't work.
Why ?
Thank you.
