1- SWT SashForm

SashForm is a class extended from Composite, it lays out child components on a row or a column. And it sets a Sash lying between 2 side-by-side child-components. The user can use mouse to change the position of Sash.
The example below is a horizontal SashForm with 3 child-compents, the user can use mouse to move the Sashes.
For example, a vertical SashForm with 4 children.
For horizontal SashForm, the width of subcomponents is directly proportional to their weight. For vertical SashForm, the height of subcomponents is directly proportional to their weight.

// Create horizontal SashForm:
SashForm sashForm = new SashForm(shell, SWT.HORIZONTAL);

// Create Vertical SashForm.
SashForm sashForm = new SashForm(shell, SWT.VERTICAL);

        Button button3 = new Button(sashForm, SWT.NONE);
        button3.setText("Button 3");
        sashForm.setWeights(new int[] { 2, 3, 1 });

        shell.setSize(400, 250);
