Create ToolTip Text in SWT
In this section, you will learn how to create ToolTip.
The ToolTip is the element of graphical user interface used in the
conjunction with a cursor pointer. In SWT, the method setToolTipText() of
class TabItem sets the tooltip text. In the given example, we have create
tabs using the class TabFolder and TabItem to show the toolTipText.
The method tabFolder.getSelection() returns the selected TabItem.
Here is the code of ToolTipExample.java
import org.eclipse.swt.SWT;
import org.eclipse.swt.widgets.*;
import org.eclipse.swt.events.*;
import org.eclipse.swt.layout.*;
public class ToolTipExample {
public void run() {
Display display = new Display();
Shell shell = new Shell(display);
shell.setLayout(new FillLayout());
shell.setText("Show ToolTips");
shell.setSize(180,150);
create(shell);
shell.open();
while (!shell.isDisposed()) {
if (!display.readAndDispatch()) {
display.sleep();
}
}
display.dispose();
}
private void create(Shell shell) {
final TabFolder tabFolder = new TabFolder(shell, SWT.NONE);
TabItem one = new TabItem(tabFolder, SWT.NONE);
one.setText("Tab 1");
one.setToolTipText("This is Tab 1.");
TabItem two = new TabItem(tabFolder, SWT.NONE);
two.setText("Tab 2");
two.setToolTipText("This is Tab 2.");
TabItem three = new TabItem(tabFolder, SWT.NONE);
three.setText("Tab 3");
three.setToolTipText("This is Tab 3.");
TabItem four = new TabItem(tabFolder, SWT.NONE);
four.setText("Tab 4");
four.setToolTipText("This is Tab 4.");
tabFolder.setSelection(2);
tabFolder.addSelectionListener(new SelectionAdapter() {
public void widgetSelected(org.eclipse.swt.events.
SelectionEvent event){
System.out.println(tabFolder.getSelection()[0].getText()
+ " selected");
}
});
}
public static void main(String[] args) {
new ToolTipExample().run();
}
}
