Hi,
I can paint a pie chart in a view only for painting this chart, but when
I try to include this chart in a formPage I can't see the pie chart.
Any idea?
CODE:
//Create part control of my view
public void createPartControl( Composite parent )
{
parent.setLayout( new GridLayout( ) );
SwtChartViewerSelector scv = new SwtChartViewerSelector( parent,
SWT.NO_BACKGROUND );
scv.setLayoutData( new GridData( GridData.FILL_BOTH ) );
scv.addPaintListener( scv );
}
//painting the chart in the formPage
SwtChartViewerSelector scv = new SwtChartViewerSelector( parent,
SWT.NO_BACKGROUND );
scv.setLayoutData( new GridData( GridData.FILL_BOTH ) );
scv.addPaintListener( scv );
//SwtChartViewerSelector

Rodrigo,
Can you email me the complete source for the project that is including
the chart in the formPage?
