Windows Forms and WPF User Interface Integration

Windows Forms and WPF User Interface Integration

In this little more complex example we integrate into an awt java user interface two different complex control, taken from two .NET library. The first control is a Windows Form, the second one is a WPF object. The application in \JVM\Java\srcAWTWinFormsWPF.java expose the complete process from the control reference and generation to the .NET event listener registration to the .NET events callback management.

import java.awt.Frame;
import java.io.IOException;
import org.mases.jcobridge.*;

public class AWTWinFormsWPF implements IJCVoidEventEmit {
	public static void main(String args[]) {
		new AWTWinFormsWPF().createAndShow();
	}

	int cycle = 0;
	java.awt.TextArea gTextArea;

	// WPF
	JCControl gControlWpfControl = null;

	// FORMS
	JCControl gControlFormsControl = null;

	void createAndShow() {
		try {
			// LOGGER
			IJCEventLog logger = null;
			try {
				try {
					JCOBridge.Initialize("");
				} catch (JCException e) {
					e.printStackTrace();
				}

				logger = new JCFileEventLog("WinFormsWPF.txt");
			} catch (IOException e) {
				e.printStackTrace();
			}

			JCOBridge bridge;

			bridge = JCOBridge.CreateNew();
			bridge.RegisterEventLog(logger);
			// adds the path where extarnal assemblies where found
			bridge.AddPath("../../CLR/Output/");

			// add REFERENCES
			bridge.AddReference("WPFTestControl");
			bridge.AddReference("WinFormsTestControl");

			// GENERATE CONTROLS
			gControlWpfControl = bridge.GetControl("MASES.CLRTests.WPFTestControl.TestControl");
			gControlFormsControl = bridge.GetControl("MASES.CLRTests.WinFormsTestControl.TestControl");

			// CONFIGURE CONTROLS
			gControlWpfControl.RegisterEventListener("FromComboBox", this);
			gControlWpfControl.RegisterEventListener("FromTextBox", this);

			gControlFormsControl.RegisterEventListener("FromComboBox", this);
			gControlFormsControl.RegisterEventListener("FromTextBox", this);

			Frame dialog = new Frame();
			gTextArea = new java.awt.TextArea();
			gTextArea.setText("This is an AWT TextArea");

			java.awt.GridLayout layout = new java.awt.GridLayout(2, 2);

			dialog.setLayout(layout);
			dialog.add(gControlWpfControl);
			dialog.add(gControlFormsControl);
			dialog.add(gTextArea);
			dialog.validate();
			dialog.setTitle("WinForms-WPF AWT integration");
			dialog.setVisible(true);
			dialog.setSize(200, 200);

		} catch (JCException jce) {
			jce.printStackTrace();
			System.console().readLine("Please press enter");

			System.out.println("Exiting");
			return;
		}
	}

	@Override
	public void EventRaised(Object... args) {
		System.out.println("EventRaised");
		if (args[1] instanceof JCObject) {
			JCObject obj = (JCObject) args[1];
			System.out.println();
			try {
				if (obj != null) {
					gTextArea.setText("Text area: event: " + obj.toString() + " Content: " + obj.Get("Content"));
				}
			} catch (JCException e) {
				e.printStackTrace();
			}
		}
	}
