Hi Puybaret..

I tried to fix my requirement as you said. Actually it is not clear to me. Anyway I found a solution to do that and mentioned below the code. Initially I set the 3D pane as 0.

HomePane - createMainPane Method

else {
final JSplitPane mainPane = new JSplitPane(JSplitPane.HORIZONTAL_SPLIT, catalogFurniturePane, planView3DPane);
// Set default divider location

mainPane.setDividerLocation(0);
configureSplitPane(mainPane, home, MAIN_PANE_DIVIDER_LOCATION_VISUAL_PROPERTY, 0.3, true, controller);
return mainPane;
}

Code for Button - Methods in HomeController.java

public void enable3DView() {

View vv = getHomeController3D().getView();
attachView(vv);

show3DView(vv);
}

/*------3D View-----------------*/

private void show3DView(final View view) {
JComponent jc = (JComponent)view;

Container parent = jc.getParent(); // dummyComponent.getParent();
if (parent instanceof JSplitPane) {
JSplitPane splitPane = (JSplitPane)parent;

int loc = splitPane.getDividerLocation();
int min = splitPane.getMinimumDividerLocation();
int max = splitPane.getMaximumDividerLocation();


if(is3DViewClicked){
splitPane.setDividerLocation(0.0);
is3DViewClicked = false;
}
else {
splitPane.setDividerLocation(1.0);
is3DViewClicked = true;
}
}

Thnak You
