Sample app for Teechart for Java is not getting compiled

[SDG]

Hello,

I am writing a sample application to test TeeChart for Java and getting following error while compiling demo Java file. Kindly advice me.
-----------------------------------------------------------------------
cannot access com.steema.teechart.drawing.ChartPen

bad class file: C:\PServer50\server\nodes\fdms_charts\archives\public_html\FDMS\TeeCharts\jars\TeeChart.Swing\com\steema\teechart\drawing\ChartPen.class

class file has wrong version 49.0, should be 48.0

Please remove or make sure it appears in the correct subdirectory of the classpath.

import com.steema.teechart.drawing.ChartPen;

Hi D486909,

Which exact TeeChart for Java version are you using? Notice that on last 27th April we posted a new version at the client area.

[SDG]

Downloaded eval version just a week back.

Hello,

Please could you describe a little more about the project setup to help us reproduce the problem. We've been unable to generate the problem using the latest evaluation version and the following steps.

Steps taken:
- new netbeans desktop application
- added TeeChart to the palette and added to form
- added button with following code:

Code: Select all

tChart1.getSeries().add(new com.steema.teechart.styles.Line());
tChart1.getSeries(0).fillSampleValues();
tChart1.getAxes().getAxis(0).getAxisPen().setWidth(4);
tChart1.getAxes().getAxis(0).getAxisPen().setColor(java.awt.Color.yellow);

The code runs successfully, modifying the two Pen characteristics of the Axis.

Hello,

I´m using the teechart component within my applications, and i´m experiencing some sort of problems. Maybe the problems are being
caused by my own applications, but the point is, when i choose to resize the application window, the border that i´ve draw on the
line with the command getOutLine().setVisible(true) increase it´s own size. I mean, i really have a default size for this border but when the window is resized, the border simply change it´s size.

Hope that you can help.

Regards,
Marcel

Hi Marcel,

I'm trying to reproduce it here with the following code in Eclipse, but the line looks the same size after resizing the window.

Code: Select all

import org.eclipse.swt.events.ControlEvent;
import org.eclipse.swt.events.ControlListener;
import org.eclipse.swt.layout.FillLayout;
import org.eclipse.swt.widgets.Display;
import org.eclipse.swt.widgets.Shell;

import com.steema.teechart.TChart;
import com.steema.teechart.misc.Utils;
import com.steema.teechart.styles.Line;

public class Test {

	static Display display;
	static Shell shell;
	static TChart tChart1;

	public static void main(String[] args) {
		display = new Display();
		shell = new Shell(display);
		shell.setLayout(new FillLayout());
		shell.setSize(800, 500);

		createChart();
		initializeChart();

		shell.open();
		while (!shell.isDisposed()) {
			if (!display.readAndDispatch()) {
				display.sleep();
			}
		}
		display.dispose();
	}

	private static void createChart() {
		tChart1 = new TChart(shell, 0);
	}

	private static void initializeChart() {
		tChart1.getAspect().setView3D(false);
		Line line1 = new Line(tChart1.getChart());
		line1.fillSampleValues();
		line1.getOutLine().setVisible(true);
		
		shell.addControlListener(new ControlListener() {
	           
            @Override
            public void controlResized(ControlEvent arg0) {
                tChart1.setBounds(Utils.fromLTRB(0, 0, shell.getSize().x, shell.getSize().y));
                tChart1.doInvalidate();
            }
           
            @Override
            public void controlMoved(ControlEvent arg0) {
            }
        });
	}
}

Could you please check the code above for you?
Could you please arrange a simple example project we can run as-is to reproduce the problem here?
