GWT SimplePager : How to provide GoTo Functionality in pager?

I am usign GWT2.3. We developed CustomPager by overriding SimplePager.

We override createText() method such a way that we are showing string like "Page 1 of 4" using following code

    public String createText() {
        if(searchRecordCount%pageSizeForText == 0){
            totalPages = searchRecordCount/pageSizeForText;
        }else{
            totalPages = (searchRecordCount/pageSizeForText) + 1;
        }
        NumberFormat formatter = NumberFormat.getFormat("#,###");
        return "Page "+formatter.format(this.getPage()+1) + " of " + formatter.format(totalPages);
      }

enter image description here

Now I want to use TextBox for CurrentPage so that user can enter page Number in textBox. (Functionality GoTo entered pageNumber)

createText() returns string so I cant user textBox ;) + Can't provide css

How can I do this ? Is there any way to solve this problem? Workaround if any or Sample code

There are two ways how to achieve this:

1.) Use HTML code to create a TextBox:

In the createText() function you can create the textbox manually by using HTML code (better use SafeHTML templates for avoiding XSS):

String textbox_str = "<input type='textbox' name='goto'>";

However you have to write code for handling the actual event (i.e. ChangeEvent) and call setPage() of your SimplePager using JSNI.

2.) Add TextBox widget to SimplePager and override constructor:

SimplePager is basically a Composite which adds ImageButtons in its constructor for the forward and backward links.
You can extend SimplePager add a TextBox and override the constructor to add the TextBox between the forward and backward ImageButtons.
