ICellPainter

public class GroupByCellTextPainter
extends TextPainter

Specialized TextPainter that is used for grouping rows. It will only render text in the tree column and in columns that contain group by summary values.

Extracted to a separate class to be able to create theme configurations where you are able to wrap this painter easily, instead of creating similar inner classes all the time.

Method Details

getTextToDisplay

protected String getTextToDisplay(ILayerCell cell,
 org.eclipse.swt.graphics.GC gc,
 int availableLength,
 String text)

Description copied from class: AbstractTextPainter

Computes dependent on the configuration of the TextPainter the text to display. If word wrapping is enabled new lines are inserted if the available space is not enough. If calculation of available space is enabled, the space is automatically widened for the text to display, and if no calculation is enabled the text is cut and modified to end with "..." to fit into the available space

Overrides:

getTextToDisplay in class AbstractTextPainter

Parameters:

cell - the current cell to paint

gc - the current GC

availableLength - the available space for the text to display

text - the text that should be modified for display

Returns:

the modified text
