Hi,
On moving an figure object with the mouse, I need to test to see
if the SHIFT or CTRL key is pressed down , can someone show
me how to test it? Also, where or which notification method should
I look into for updating the information of the figure being moved?
Thanks
SL

public class CreationTool
extends TargetingTool
{
.............................................
protected void updateTargetRequest() {
CreateRequest req = getCreateRequest();
if (isInState(STATE_DRAG_IN_PROGRESS)) {
Point loq = getStartLocation();
Rectangle bounds = new Rectangle(loq, loq);
bounds.union(loq.getTranslated(getDragMoveDelta()));
req.setSize(bounds.getSize());
req.setLocation(bounds.getLocation());
req.getExtendedData().clear();
if (!getCurrentInput().isAltKeyDown() && helper != null) {
<------------------------------------------
PrecisionRectangle baseRect = new PrecisionRectangle(bounds);
PrecisionRectangle result = baseRect.getPreciseCopy();
helper.snapRectangle(req, PositionConstants.NSEW,
baseRect, result);
req.setLocation(result.getLocation());
req.setSize(result.getSize());
}
} else {
req.setSize(null);
req.setLocation(getLocation());
}
}
Mostly it depends in which class you want to check key state

Well, what I need to do is when the user moves the figure,
I need to move all its child nodes along (only when the SHIFT
key is pressed). That is, I need to update all the child node's
location when the parent node is moved. How do I do it?
How to register or use the TargetingTool with the figure?
Thanls

From your drag tracker, you can call getCurrentInput().isShiftKeyDown().

Hi Randy,
I am not using the Drag Tracker at all. Is there a way that I can found
out whether the SHIFT key is pressed (from any code)?
Thanks

So, you are using just draw2d? The mouse event should have as much
information in it as an SWT mouse event. Determining if the SHIFT key is
down is the same as it is in SWT. You could also just look at the code for
the method I pointed you to.
