CellTable CheckboxCell setTitle()

[Vivek Dudani]

Hi,

I need to set tooltip for CheckboxCell which i'm adding in a
cellTable.
created a new CheckboxCell and then added it to CellTable header.

cannot find any setTitle or anything else.
Even tried with below code :

public void setTitle(String title){
if (title == null || title.length() == 0) {
DOM.removeElementAttribute(getElement(), "title");
} else {
DOM.setElementAttribute(getElement(), "title", title);
}
}

private Element element;

public com.google.gwt.user.client.Element getElement() {
return (com.google.gwt.user.client.Element) element;
}

This too didn't worked.
Can somebody please help me out on this.

Best Regards,
Vivek Dudani

Override the method CheckboxCell.render(..) and add the title attribute as a string (see source of CheckboxCell).

CheckboxCell is part of the CellWidget family and don't extend from Widget, which make them fast and lightweight.

See: http://code.google.com/webtoolkit/doc/latest/DevGuideUiCellWidgets.html

Because they don't extend from Widget that don't have methods like setTitle. 

If you want to use a setTitle() method, then use the CheckBox widget.

Hey,

can u help me out with one more issue..
I need to add title for each row as "Select row 1", "Select row 2"...
and so on.
can we put some dynamic string inside title attribute that will show
row number in title(i.e. tooltip) for each row or any other way of
achieving it?

Please workaround if any.

Thanks,
Vivek

Hey Vivek,

this might be relevant for you:

In GWT 2.5, you'll be able to provide your own CellTableBuilder
(you'll
probably subclass the DefaultCellTableBuilder) and add a title=""
attribute
on any <tr> or <td> you'd like.
---

I suppose using this CellTableBuilder you could make it so that each
row has a certain title assigned to it (even though I'm not sure,
whether TR-elements are even allowed to have a title-attribute at
all). I didn't try it myself, since I'm still on 2.4. But I moved my
requirement of having this to a different milestone. Therefore I'll
implement the titles when I get to reworking my application once GWT
2.5 is out.

Igor.
