How to set static width to view in SWT

问题

how can be configured static width of view in perspective?

I'd like have on left side TreeViewer with static width and second view (ViewPart) want to expand horizontaly. I have this, witch used ratio, that i don't want:

public class PerspectivaEkomaj implements IPerspectiveFactory {

    @Override
    public void createInitialLayout( IPageLayout layout ) {

        String editorArea = layout.getEditorArea();
        layout.setEditorAreaVisible( false );
        layout.addView( EkomajTreeView.RCP_ID, IPageLayout.LEFT, 0.25f, editorArea );
        layout.getViewLayout( EkomajTreeView.RCP_ID ).setCloseable( false );

        layout.addStandaloneView( MajetekView.RCP_ID, false, IPageLayout.TOP, 0.75f, editorArea );
        layout.addStandaloneViewPlaceholder( MajetekDMView.RCP_ID, IPageLayout.TOP, 0.75f, editorArea, false );
...

Pls let me know if exist some work around or similar class (compatible with SWT) that allow it.

回答1:

If you want to control the size of a specific workbench part (view or editor), have a look at the org.eclipse.ui.ISizeProvider interface. If a workbench part can be adapted to ISizeProvider, then this is used to calculate the resulting size. See org.eclipse.ui.internal.WorkbenchPartReference.computePreferredSize(...) for the relevant adapter code...
