SmartGWT: hide a column in a grouped grid (which makes the group)

问题

I have a SmartGWT grid, where I want to display some data from JBoss-Server and it's grouped by one textfield that I fetch from JSON.

So, but I want this textfield only in the header of each group.

When I do .hideField on this field, then i'm loosing the group.

grid.hideField("pool");

But when i hide it over the context-menue of the grid header, the column remains.

Any idea how to do this?

回答1:

There is simple and clean workaround. Just set width parameter of the filed to '0'. Additionally clear title parameter if you have one (but this is only necessary in some sophisticated ListGrid use cases).

回答2:

I've actually had the most success hiding the field using the DataSourceField as opposed to the grid itself.

DataSource ds = new DataSource() {
    {
        DataSourceTextField field = new DataSourceTextField();
        field.setHidden(true);

        addField(field);
    }
}

You've already posted here and didn't answer to the people who oriented you toward the setHidden methode of the ListGridField.

回答4:

The clean way is to hide the ListGridField like this:

    ListGridField groupField = new ListGridField(FLD_CATEGORY, "Group");
    groupField.setHidden(true);

Note that if you use a DataSourceField, you may need to declare hard-coded ListGridField definitions
