Hi Domenic,

you should override shouldCreateToolTip() of your DefaultToolTip. There you can define when to show the tooltip.

Hi Domenic,

I have created some general NatTableContentTooltip on the 0.9 head. See bug 384800 on bugzilla. It can be configured to show only on specified grid regions and will render nothing if the cell is empty.

Greez,
Dirk

Hi Domenic,

NatTableContentTooltip is not an example, it is a default implementation for adding tooltips on a NatTable instance. It is checked in the current master in git. You can find it in package org.eclipse.nebula.widgets.nattable.tooltip. Have a look at the new documentation pages to see how to check out the current master from git.

Greez,
Dirk

Hi,

I could not find any downloads, the download page (http://eclipse.org/nattable/download.php) says: Downloads will coming soon...

Thanks,

Hi Domenic,

sorry for the misunderstanding. Current development is only checked into the source code repository. As we haven't released a Nebula version yet, there are no downloads so far. So if you want to benefit from current development, you need to checkout the sources as described here (http://eclipse.org/nattable/documentation.php?page=getting_started).

If this still doesn't help you I can try to post the source code of NatTableContentTooltip here. But it would be better to checkout the sources.

Greez,
Dirk

Hi,

there was an error with the manifest. I forgot to add the package to be exported. (https://bugs.eclipse.org/bugs/show_bug.cgi?id=385444).
Thanks to Adrian Lewty who pointed me to this.

Hi,

SVN is closed. With the move from sourceforge to Nebula we moved to a git repository. Look here (http://eclipse.org/nattable/documentation.php?page=getting_started)

Hi Domenic,

sorry, I thought you are using the NatTable sources and not ready to use builds.

We are currently working on a stable version under Nebula. If you want to benefit from enhancements and bugfixes without relying to stable versions, you need to checkout the sources from Git and build a SNAPSHOT version yourself.

As the NatTableContentTooltip also works with a 2.3.2 Sourceforge version of NatTable, I post the code here so you can use it by adding it into your application. This way you don't have to checkout the sources and build NatTable yourself until a stable Nebula NatTable version is released.

public class NatTableContentTooltip extends DefaultToolTip {
	
	/**
	 * The {@link NatTable} instance for which this {@link ToolTip} is used. 
	 */
	private NatTable natTable;
	/**
	 * The regions of the {@link NatTable} for which this {@link ToolTip} is
	 * active.
	 */
	private String[] tooltipRegions;
	
	/**
	 * Creates a new {@link ToolTip} object, attaches it to the given {@link NatTable}
	 * instance and configures and activates it.
	 * @param natTable The {@link NatTable} instance for which this {@link ToolTip} is used.
	 * @param tooltipRegions The regions of the {@link NatTable} for which this {@link ToolTip} is
	 * 			active. If none are given, the tooltip will be active for all regions.
	 */
	public NatTableContentTooltip(NatTable natTable, String... tooltipRegions) {
		super(natTable, ToolTip.NO_RECREATE, false);
		setPopupDelay(500);
		setShift(new Point(10, 10));
		activate();
		this.natTable = natTable;
		this.tooltipRegions = tooltipRegions;
	}
	
	/**
	 * {@inheritDoc}
	 * 
	 * <p>Implementation here means the tooltip is not redrawn unless mouse hover moves outside of the
	 * current cell (the combination of ToolTip.NO_RECREATE style and override of this method).
	 */
	protected Object getToolTipArea(Event event) {
		int col = natTable.getColumnPositionByX(event.x);
		int row = natTable.getRowPositionByY(event.y);
		
		return new Point(col, row);
	}
	
	/**
	 * {@inheritDoc}
	 * 
	 * <p>Evaluates the cell for which the tooltip should be rendered and checks the
	 * display value. If the display value is empty <code>null</code> will be returned
	 * which will result in not showing a tooltip.
	 */
	@Override
	protected String getText(Event event) {
		int col = natTable.getColumnPositionByX(event.x);
		int row = natTable.getRowPositionByY(event.y);
		
		ILayerCell cell = natTable.getCellByPosition(col, row);
		if (cell != null) {
			String tooltipValue = CellDisplayConversionUtils.convertDataType(
					cell, 
					natTable.getConfigRegistry());
			
			if (tooltipValue.length() > 0) {
				return tooltipValue;
			}
		}
		return null;
	}
	
	/**
	 * {@inheritDoc}
	 * 
	 * <p>Will only display a tooltip if the value of the cell for which the tooltip 
	 * should be rendered is not empty.
	 * <p>If there are regions configured for which the tooltip should be visible, it
	 * is also checked if the the region for which the tooltip should be rendered is 
	 * in one of the configured tooltip regions.
	 */
	@Override
	protected boolean shouldCreateToolTip(Event event) {
		//check the region?
		boolean regionCheckPassed = false;
		if (this.tooltipRegions.length > 0) {
			LabelStack regionLabels = natTable.getRegionLabelsByXY(event.x, event.y);
			if (regionLabels != null) {
				for (String label : this.tooltipRegions) {
					if (regionLabels.hasLabel(label)) {
						regionCheckPassed = true;
						break;
					}
				}
			}
		}
		else {
			regionCheckPassed = true;
		}

		if (regionCheckPassed && getText(event) != null) {
			return super.shouldCreateToolTip(event);
		}
		
		return false;
	}

}


Hope this helps!

Greez,
Dirk
