Ah, I need to dispose of the image before disposing of the
display.

When using both simpleimage and DWT my program crashes with
core.exception.InvalidMemoryOperationError after I show an
image in a GUI window and then close the window. I'm presumably
misunderstanding something about how the windows deal with
memory deallocation, but this happens even when copying
tutorial examples.
e.g.
module main;
import org.eclipse.swt.SWT;
import org.eclipse.swt.widgets.Display;
import org.eclipse.swt.widgets.Label;
import org.eclipse.swt.widgets.Shell;
import org.eclipse.swt.graphics.all;
void main ()
{
auto display = new Display;
auto shell = new Shell;
shell.setText(Title);
Label label = new Label (shell, SWT.BORDER);
label.setBounds(shell.getClientArea());
Image image = new Image(display, C:/dev/data/tree.png);
label.setImage(image);
shell.pack();
shell.open();
while (!shell.isDisposed)
if (!display.readAndDispatch())
display.sleep();
display.dispose();
}
This successfully creates the display and shows an image, but
when I close the window the memory error exception is thrown.
If I run the same code without creating the image then there's
no errors. If I create the image without setting it on the
label I still get the error. Any ideas?
