Line Numbering in text editors [message #290913]

Hi,

Quick question. When I invoke createLineNumberRulerColumn(), a column
appears but the numbers don't. How do you configure the column to show
them?

I thought using initializeLineNumberRulerColumn() would work, but it is
called from within createLineNumberRulerColumn(). Any thoughts?

Thanks.

Matt

Could it be that your preference store does not contain the values
needed by initializeLineNumberRulerColumn()? You should set a preference
store to your editor that either contains these values (see
AbstractDecoratedTextEditorPreferenceConstants.initializeDef aultValues)
or use a hierarchical preference store that forwards to the EditorsUI
preferences (see ChainedPreferenceStore).
