SWT: TabFolder widget

By using TabFolder class, you can define TabFolder widget. Only one of the styles TOP and BOTTOM may be specified.

Ex:

TabFolder employeeInfoTab = new TabFolder(shell, SWT.NONE);

employeeInfoTab.setBounds(10, 10, tabWidth, tabHeight);

You can create a tab items using TabItem class. Suppose, I want to add two tabs like "Personal Information", "Professional Information" to employeeInfoTab.

TabItem personalInfo = new TabItem(employeeInfoTab, SWT.NONE);

personalInfo.setText("Personal Information");

TabItem professionalDetails = new TabItem(employeeInfoTab, SWT.NONE);

professionalDetails.setText("Professional Information");

You ca add any widgets to the tab items using ‘setControl’ method.

personalInfo.setControl(personalnfoTable);

professionalDetails.setControl(professionalInfoTable);

Ideal way is add all the widgets to a composite and add the composite to the tab item.

Following is the complete working application.
