Re: How to change style of a button inside a ButtonCell

I created this class and it worked:

package ve.com.rapipago.pagueaqui.vista.client.componente;

import com.google.gwt.cell.client.AbstractCell;

import com.google.gwt.cell.client.ValueUpdater;

import com.google.gwt.dom.client.Element;

import com.google.gwt.dom.client.NativeEvent;

import com.google.gwt.resources.client.ImageResource;

import com.google.gwt.safehtml.shared.SafeHtml;

import com.google.gwt.safehtml.shared.SafeHtmlBuilder;

import com.google.gwt.safehtml.shared.SafeHtmlUtils;

import com.google.gwt.user.client.ui.AbstractImagePrototype;

public class ClickableImageResourceCell extends AbstractCell<ImageResource> {

    public ClickableImageResourceCell() {

        super("click");

    }

    @Override

    public void render(Context context, ImageResource value, 

                       SafeHtmlBuilder sb) {

        if (value != null) {

            SafeHtml html = 

                SafeHtmlUtils.fromTrustedString(AbstractImagePrototype.create(value).getHTML());

            sb.append(html);

        }

    }

    @Override

    public void onBrowserEvent(Context context, Element parent, ImageResource resource, 

                               NativeEvent event, 

                               ValueUpdater<ImageResource> valueUpdater) {

        super.onBrowserEvent(context, parent, resource, event, valueUpdater);

        if ("click".equals(event.getType())) {

            onClick(resource, event);

        }

    }

    public void onClick(ImageResource resource, 

                        NativeEvent event) {

    }

}

Hope its useful.

Hi

I'm trying to change the CSS style of a button inside a ButtonCell so I can set an image but the getStyleName method on ButtonCell won't do anything in the HTML. Also the styleName that you set on the column is not applied to the TD cell but the column in the column group. So I haven't found a way to set a CSS style for the button.

Regards,

Néstor Boscán
