Difference between Mac and PC

[hanland]

Hi,

I have an RCP application which uses SWT designer to create the form layouts. I have noticed an annoying difference between the Mac and the PC. This relates to the Group headings. Using grid layouts, the Mac version truncates the group title, but not on the PC. As the user can set the font size I can't rely on width hints to solve this one. I have two small screen shots showing the difference in the designer. The group is using fill but not grab as I just want the group contents to be contained and no more, as with the PC version.

Any ideas how to get around this one?

Thanks in advance.

This is using eclipse 3.5, and SWT designer Pro, last Instantiations version and Google version (same result)

Looks like an SWT OSX bug.

Have you told that column/cell to grab all of the remaining space?

In general, it is a lot easier to diagnose issues like this with an actual test case.

The grab is not an option as this would expand the group to cover 85 % of the screen.

I will put a test case together.

OK a test case with two screen shots.

Code: Select all

package uk.hsoft.reports.forms;

import org.eclipse.swt.widgets.Composite;

public class TextCase extends FormPage {

   /**
    * Create the form page.
    * @param id
    * @param title
    */
   public TextCase(String id, String title) {
      super(id, title);
   }

   /**
    * Create the form page.
    * @param editor
    * @param id
    * @param title
    * @wbp.parser.constructor
    * @wbp.eval.method.parameter id "Some id"
    * @wbp.eval.method.parameter title "Some title"
    */
   public TextCase(FormEditor editor, String id, String title) {
      super(editor, id, title);
   }

   /**
    * Create contents of the form.
    * @param managedForm
    */
   @Override
   protected void createFormContent(IManagedForm managedForm) {
      FormToolkit toolkit = managedForm.getToolkit();
      ScrolledForm form = managedForm.getForm();
      form.setText("Empty FormPage");
      Composite body = form.getBody();
      toolkit.decorateFormHeading(form.getForm());
      toolkit.paintBordersFor(body);
      managedForm.getForm().getBody().setLayout(new GridLayout(2, false));
      
      Group grpGroup = new Group(managedForm.getForm().getBody(), SWT.NONE);
      grpGroup.setText("Group 1");
      grpGroup.setLayoutData(new GridData(SWT.FILL, SWT.CENTER, true, false, 2, 1));
      managedForm.getToolkit().adapt(grpGroup);
      managedForm.getToolkit().paintBordersFor(grpGroup);
      
      Group grpGroup_1 = new Group(managedForm.getForm().getBody(), SWT.NONE);
      grpGroup_1.setText("Group 2");
      managedForm.getToolkit().adapt(grpGroup_1);
      managedForm.getToolkit().paintBordersFor(grpGroup_1);
      
      Group grpGroup_2 = new Group(managedForm.getForm().getBody(), SWT.NONE);
      grpGroup_2.setText("Group  xxxxxxx 3");
      managedForm.getToolkit().adapt(grpGroup_2);
      managedForm.getToolkit().paintBordersFor(grpGroup_2);
   }
}

You can use GridData.minimumWidth property in combination with grab (see Javadoc).

As I said in the original post "As the user can set the font size I can't rely on width hints to solve this one". OK if thats the only way to get around it then so be it, but it would be nice if it worked properly.

t it would be nice if it worked properly.

I agree. Unfortunately, it isn't an SWT Designer issue. All we can do is present what the OS renders for us.

This is an OSX "feature" that directly impacts SWT/OSX.
