Creates a new ToolTip object, attaches it to the given NatTable instance and configures and activates it.

tooltipRegions - The regions of the NatTable for which this ToolTip is active. If none are given, the tooltip will be active for all regions.

Method Detail

getToolTipArea

protected Object getToolTipArea(org.eclipse.swt.widgets.Event event)

Overrides:

getToolTipArea in class org.eclipse.jface.window.ToolTip

getText

protected String getText(org.eclipse.swt.widgets.Event event)

Evaluates the cell for which the tooltip should be rendered and checks the display value. If the display value is empty null will be returned which will result in not showing a tooltip.

Overrides:

getText in class org.eclipse.jface.window.DefaultToolTip

isVisibleContentPainter

protected boolean isVisibleContentPainter(ICellPainter painter)

Checks if the given ICellPainter is showing the content directly or if it is anonymized by using the PasswordTextPainter

Parameters:

painter - The ICellPainter to check.

Returns:

true if the painter is not a PasswordTextPainter

shouldCreateToolTip

protected boolean shouldCreateToolTip(org.eclipse.swt.widgets.Event event)

Will only display a tooltip if the value of the cell for which the tooltip should be rendered is not empty.

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.

Overrides:

shouldCreateToolTip in class org.eclipse.jface.window.ToolTip
