Problem with Local / absolute coordinates [message #167070]

Hi !

I need to place a figure inside a container based on the coordinates of
another figure inside another container figure.

My problem is that I get absolutes coordinates from my model and so
cannot place the second figure correctly.

I would like to translate these absolute coordinates in local
coordinates relative to the parent figure, but I can't manage to do it
using translateFromParent.

How can I do it ?

TIA

the locations methods in my model classes look like that :

/**
* Set the Location of this bean.
* @param newLocation a non-null Point instance
* @throws IllegalArgumentException if the parameter is null
*/
public void setBeanLocation(Point newLocation) {
if (newLocation == null) {
throw new IllegalArgumentException();
}
location.setLocation(newLocation);
firePropertyChange(LOCATION_PROP, null, location);
}

public Point getBeanLocation() {
return location.getCopy();
}

Your problem's not exactly clear to me. So, you want to place figure F2 in
container figure C2 based on F1's location in C1? Why is that? What are
you trying to do? Do C1 and C2 have the same coordinate system and same
parent? Do you have any figures that use relative coordinates?

Try: c1.translateToRelative(coordinates)

OK, I did it another way.

Thanks anyway for the response.
