Smiley Drag and Drop ?
Hallo zusammen,

ich wollte dieses Beispiel im JBuilder aus probieren, nur weiß ich nicht wie ich das umzubauen habe. Damit ich es auführen kann.

Es wäre super, wenn mir jemand dabei helfen könnte. Danke!

import org.eclipse.swt.widgets.Tree;

import org.eclipse.swt.widgets.TreeItem;



public class SimpleDNDExample {



public static void main(String[] args) {

Shell shell = new Shell();

shell.setLayout(new FillLayout());



// Create the tree and some tree items

final Tree tree = new Tree(shell, SWT.NONE);

TreeItem item1 = new TreeItem(tree, SWT.NONE);

item1.setText("Item 1");

TreeItem item2 = new TreeItem(tree, SWT.NONE);

item2.setText("Item 2");

TreeItem item3 = new TreeItem(tree, SWT.NONE);

item3.setText("Item 3");

TreeItem item4 = new TreeItem(tree, SWT.NONE);

item4.setText("Item 4");



// Create the drag source on the tree

DragSource ds = new DragSource(tree, DND.DROP_MOVE);

ds.setTransfer(new Transfer[] { TextTransfer.getInstance() });

ds.addDragListener(new DragSourceAdapter() {

public void dragSetData(DragSourceEvent event) {

// Set the data to be the first selected item's text

event.data = tree.getSelection()[0].getText();

}

});



// Create the button

final Button button = new Button(shell, SWT.FLAT);

button.setText("Button");

button.setAlignment(SWT.CENTER);



// Create the drop target on the button

DropTarget dt = new DropTarget(button, DND.DROP_MOVE);

dt.setTransfer(new Transfer[] { TextTransfer.getInstance() });

dt.addDropListener(new DropTargetAdapter() {

public void drop(DropTargetEvent event) {

// Set the buttons text to be the text being dropped

button.setText((String) event.data);

}

});



shell.pack();

shell.open();

Display display = Display.getDefault();

while (!shell.isDisposed())

if (!display.readAndDispatch())

display.sleep();

display.dispose();

}



}
