Programmatically retrieve the tabsize of eclipse

I am writing a plugin which needs to retrieve the tab size setting of eclipse.

That is the 'Windows > Preferences > General > Editor > Text Editors > Displayed tab width' setting

Does anyone have any idea how to achieve this? Thank for your help.

Solution

  • If your code is in a text editor extending TextEditor you can get the tab setting from the source viewer configuration using:

    getSourceViewerConfiguration().getTabWidth(getSourceViewer());

    elsewhere you could use:

    IPreferenceStore store = EditorsUI.getPreferenceStore();

store.getInt(AbstractDecoratedTextEditorPreferenceConstants.EDITOR_TAB_WIDTH));
