Hi,
I have a GUI and in this GUI I have a toolbar and a textbox under the toolbar.

I would like to add a title (named "Files in List") to the textbox field. (I marked it in red in the attachment)

Also, I would like to put some note into the textbox in light gray color to give some information to the user about how to use the textbox. But this light gray text should disappear when you click on the textbox field. (I marked it in blue in the attachment)

This is the code I used to create the text box. I added this code after the creation of all the tabs.

        //This is the text box
        GridData txtGridData = new GridData(GridData.FILL_BOTH); txtGridData.horizontalSpan = 2;
        Text txt = new Text(compTab1, SWT.MULTI | SWT.BORDER | SWT.WRAP | SWT.V_SCROLL);
        txt.setLayoutData(txtGridData); 

Open in new window


I am sending a screen shot in the attachment to show the view.

there is another widget called Group, it's used to implement your requirement. Just replace the code above with this one. Also add to your project attached file. To the text box is added FocusListener. When the text box gain the focus and the text is the one you want/description text/ it's cleared and foreground color is set to black. when focus is lost and there is nothig entered into the box the description text is set back and foreground color is set to gray.

GridLayout groupLayout = new GridLayout();
        GridData groupGD = new GridData(GridData.FILL_BOTH);
        Group groupText = new Group(compTab1, SWT.NONE);
        groupText.setLayout(groupLayout);
        groupText.setLayoutData(groupGD);
        groupText.setText("Files in List");
       
        GridData txtGridData = new GridData(GridData.FILL_BOTH);
        Text txt = new Text(groupText, SWT.MULTI | SWT.BORDER | SWT.WRAP | SWT.V_SCROLL);
        TxtFocusListener txtFL = new TxtFocusListener(compTab1);
        txt.setLayoutData(txtGridData);
        txt.addFocusListener(txtFL);
        txt.setText(TxtFocusListener.introText); txt.setForeground(compTab1.getDisplay().getSystemColor(SWT.COLOR_GRAY));
TxtFocusListener.java
