Examples with TransformMediator org.uberfire.ext.wires.core.grids.client.widget.layer.pinning.TransformMediator used on opensource projects

Example 1 with TransformMediator

use of org.uberfire.ext.wires.core.grids.client.widget.layer.pinning.TransformMediator in project drools-wb by kiegroup.

the class GuidedDecisionTableModellerViewImpl method setZoom.

@Override
public void setZoom(final int zoom) {
    // Set zoom preserving translation
    final Transform transform = newTransform();
    final double tx = gridPanel.getViewport().getTransform().getTranslateX();
    final double ty = gridPanel.getViewport().getTransform().getTranslateY();
    transform.translate(tx, ty);
    transform.scale(zoom / 100.0);
    // Ensure the change in zoom keeps the view in bounds. IGridLayer's visibleBounds depends
    // on the Viewport Transformation; so set it to the "proposed" transformation before checking.
    gridPanel.getViewport().setTransform(transform);
    final TransformMediator restriction = mousePanMediator.getTransformMediator();
    final Transform newTransform = restriction.adjust(transform, gridLayer.getVisibleBounds());
    gridPanel.getViewport().setTransform(newTransform);
    gridPanel.getViewport().batch();
    gridPanel.refreshScrollPosition();
}
