shell.setSize(450, 300);
shell.setLayout(new FillLayout());
TabFolder folder = new TabFolder(shell, SWT.NONE);
// Tab 1
TabItem tab1 = new TabItem(folder, SWT.NONE);
tab1.setText("Tab 1");
// Create the HORIZONTAL SashForm.
SashForm sashForm = new SashForm(folder, SWT.HORIZONTAL);
new Button(sashForm, SWT.PUSH).setText("Left");
new Button(sashForm, SWT.PUSH).setText("Right");
sashForm.setWeights(new int[]{1,2});
tab1.setControl(sashForm);
// Tab 2
TabItem tab2 = new TabItem(folder, SWT.NONE);
tab2.setText("Tab 2");
Group group = new Group(folder, SWT.NONE);

SashForm sashForm = new SashForm(folder, SWT.HORIZONTAL);
new Button(sashForm, SWT.PUSH).setText("Left");
new Button(sashForm, SWT.PUSH).setText("Right");
sashForm.setWeights(new int[] { 1, 2 });
tab1.setControl(sashForm);
// Tab 2 with close icon
CTabItem tab2 = new CTabItem(folder, SWT.NONE | SWT.CLOSE);
tab2.setText("Tab 2");
Group group = new Group(folder, SWT.NONE);
group.setText("Group in Tab 2");

tab2.setControl(group);
// Tab 3 with close icon
CTabItem tab3 = new CTabItem(folder, SWT.NONE | SWT.CLOSE);
tab3.setText("Tab 3");
shell.open();
while (!shell.isDisposed()) {
if (!display.readAndDispatch())
display.sleep();
}
display.dispose();
}
}

item.setText("TabItem " + i);
Button button = new Button(tabFolder, SWT.PUSH);
button.setText("Page " + i);
item.setControl(button);
}
// Events
tabFolder.addSelectionListener(new SelectionAdapter() {
@Override
public void widgetSelected(SelectionEvent evt) {
TabItem item = tabFolder.getSelection()[0];
labelLog.setText(item.getText() + " selected!");
}
});
buttonNext.addSelectionListener(new SelectionAdapter() {
@Override
public void widgetSelected(SelectionEvent evt) {
int idx = tabFolder.getSelectionIndex();
if (idx + 1 == tabFolder.getItemCount()) {
idx = -1;
}
tabFolder.setSelection(idx + 1);
}
});
shell.open();
while (!shell.isDisposed()) {
if (!display.readAndDispatch())
display.sleep();
