Render empty Jtable

Question

I have JTable in my swing app. In case if model is empty (row count == 0) I want to show text "0 Results". How can I do this?

What is the thing you cannot figure out: how to get the row count or how to display the text? Where do you want to display the "0 Results" text? — Dan D., Aug 23 '12 at 10:03
Use a `JLabel`; Take a look a `JLayer` (Java 7) or `JXLayer` (Java 6 or below) — MadProgrammer, Aug 23 '12 at 10:09
I'm looking for solution similar to GWT CellTable http://google-web-toolkit.googlecode.com/svn/javadoc/latest/com/google/gwt/user/cellview/client/CellTable.html#setEmptyTableWidget(com.google.gwt.user.client.ui.Widget) — KrzyH, Aug 23 '12 at 10:19
which part of it? Keep in mind that I'm not familiar with gwt, so better explain what exactly you want or reference a screenshot ... — kleopatra, Aug 23 '12 at 11:15
My link was not truncated :) http://google-web-toolkit.googlecode.com/svn/javadoc/latest/com/google/gwt/user/cellview/client/CellTable.html#setEmptyTableWidget(com.google.gwt.user.client.ui.Widget) CellTable provides method setEmptyTableWidget(Widget widget) which I find very usefull. — KrzyH, Aug 24 '12 at 11:41

you can to use and to put text (and or with Icon / ImageIcon) in JLabel to the

GlassPane (common and basic workaround)
JViewport
mentioned JLayer (based on JXLayer)

if you extend AbstractTableModel, as shown in this example, you can check the size of your chosen data structure and condition the overridden methods to return a single row and column having the desired value. For example,

@Override
public Object getValueAt(int row, int col) {
    if (keys.length == 0) {
        return "No results.";
    }
    ...
}

Related changes would be required in the constructor and remaining methods getRowCount(), getColumnCount() and getColumnName().

If the JTable has 5 columns, wouldn't you get 'No result' displayed 5 times ? – aymeric Aug 23 '12 at 18:39
@aymeric: Only if you do not similarly condition any other overridden methods. The view displays what the model provides. – trashgod Aug 23 '12 at 19:29
