sunnymanmanMemberHi, Friends:
I have following code it imports myEclipse’s packages, but when I tried to write it in myEclipse IDE, it shows red,import org.eclipse.swt.dnd.*; // Enable a label as a Drag Source final Label dragLabel = new Label(shell, SWT.BORDER); dragLabel.setText("text to be transferred"); // Allow data to be copied or moved from the drag source int operations = DND.DROP_MOVE | DND.DROP_COPY; DragSource source = new DragSource(dragLabel, operations); // Provide data in Text format Transfer[] types = new Transfer[] {TextTransfer.getInstance()}; source.setTransfer(types); source.addDragListener(new DragSourceListener() { public void dragStart(DragSourceEvent event) { // Only start the drag if there is actually text in the // label - this text will be what is dropped on the target. if (dragLabel.getText().length() == 0) { event.doit = false; } } public void dragSetData(DragSourceEvent event) { // Provide the data of the requested type. if (TextTransfer.getInstance().isSupportedType(event.dataType)) { event.data = dragLabel.getText(); } } public void dragFinished(DragSourceEvent event) { // If a move operation has been performed, remove the data // from the source if (event.detail == DND.DROP_MOVE) dragLabel.setText(""); } } });
here
[1]. there is no constructor like DragSource source = new DragSource(dragLabel, operations);
and constructor for:
final Label dragLabel = new Label(shell, SWT.BORDER);only DragSource source = new DragSource();
and final Label dragLabel = new Label();why??
where can I get them??
[2]. also, method source.setTransfer(types);
is not available.how can I get this method when I import this package import org.eclipse.swt.dnd.*; ??
[3]. whole method
source.addDragListener(new DragSourceListener() { …}
is not available, how can I get it??Thanks a lot
