Answer 1

For JavaFX8: If you create your view from .fxml file, you can set divider's position using the attribute dividerPosition of the node SplitPane:

<SplitPane dividerPositions="0.3">

</SplitPane>

Answer 2

Use css to change the width of the divider:

.split-pane > .split-pane-divider {  
    -fx-padding: 0 0.75em 0 0.75em;  
}
