HeaderHoverHandler not working for ListGrid

[savamilovanovic@yahoo.com]

Hi,

We’re using SmartGWT 4.0p (November 2013 release) and GWT 2.5. Our goal is to add dynamic tooltip text for ListGrid component.
Browsers: Chrome 34, Firefox 26, 28, IE 9

There are following examples where used from your showcase:
http://www.smartclient.com/smartgwt/showcase/#grid_interaction_header_hover

We tried to add something like that into your code:
countryGrid.addHeaderHoverHandler(new HeaderHoverHandler() {
@Override
public void onHeaderHover(HeaderHoverEvent event) {
SC.say(event.getFieldNum() + "");
}
});

We found that nothing happens on header hover, moreover the gwt:debug showed the same. We put break point on SC.say(event.getFieldNum() + ""); and it’s not reached.
However, the countryGrid.addHeaderClickHandler works as designed.

What we are doing wrong? Any ideas?

Thanks a lot in advance,
Sava

Please try with the latest patched version of 4.0, or better yet, move to 4.1. 4.0 will soon stop receiving non-critical updates.

If the problem still persists, post the full version you are using - remember to always do this.

Thanks. What is the URL for the patched 4.0.4 version? Is that https://smartclient.com/builds/SmartGWT/4.0p?

Thanks,
Sava.

HeaderHoverHandler still not working for ListGrid with 4.0.4

We tried your latest 4.0p and issue still exists. Migration to 4.1 is not an option for us now because of the possible regression.
Use case:
1) Mouse pointer hover Flag, Country, Capital, Nationhood
2) Text hint with Random.nextInt() + "TEST" appear

Actual: old hint shows countryCodeField.setPrompt("Small image of national flag"); and others
Expected: hint with Random.nextInt() + "TEST" appear


The source we’re using for test are below (original one on http://www.smartclient.com/smartgwt/showcase/#grid_interaction_header_hover):

        countryGrid.setWidth(500);
        countryGrid.setHeight(224);
        countryGrid.setShowAllRecords(true);
 
        ListGridField countryCodeField = new ListGridField("countryCode", "Flag", 50);
        countryCodeField.setAlign(Alignment.CENTER);
        countryCodeField.setType(ListGridFieldType.IMAGE);
        countryCodeField.setImageURLPrefix("flags/16/");
        countryCodeField.setImageURLSuffix(".png");
        countryCodeField.setPrompt("Small image of national flag");

        nationHoodField.setType(ListGridFieldType.DATE);
        nationHoodField.setPrompt("Date of sovereignty, founding, or other significant nationhood event");
 
        countryGrid.setFields(countryCodeField, nameField, capitalField, nationHoodField);
        countryGrid.setCanResizeFields(true);
        countryGrid.setData(CountrySampleData.getRecords());
        countryGrid.addHeaderHoverHandler(new HeaderHoverHandler() {
            @Override
            public void onHeaderHover(HeaderHoverEvent event) {
                countryGrid.getField(event.getFieldNum()).setPrompt(Random.nextInt() + "TEST");//put break point here – never riched
            }
        });
 
        countryGrid.draw();
    }
 
}

The issue here is a subtle one - the specified "prompt" is being used in preference to the header hover behavior.
If you remove the prompts from the listGrid field, the hover notification method should run as expected.
If you want to show customized hover prompts, you can use the Hover.show() API.

We'll look into whether we can make the interaction with specified prompts more intuitive going forward but we will likely not be porting any changes to that area back to 4.0

Actually on further investigation it appears this method may not be firing when it should. We're performing some more investigation and will follow up with more information when we have it.
