I have the following code (abridged):
parent.setLayout(new GridLayout(1, false));
cmpHeader = new Composite(parent, SWT.NONE);
GridLayout gl_cmpHeader = new GridLayout(9, false);
gl_cmpHeader.verticalSpacing = 0;
gl_cmpHeader.marginWidth = 0;
gl_cmpHeader.marginHeight = 0;
cmpHeader.setLayout(gl_cmpHeader);
cmpHeader.setLayoutData(new GridData(SWT.FILL, SWT.CENTER, true, false, 1, 1));
Button btnSPrev = new Button(cmpHeader, SWT.NONE);
btnSPrev.setLayoutData(new GridData(SWT.CENTER, SWT.CENTER, false, false, 1, 1));
btnSPrev.setText("SPrev");
btnSPrev.addSelectionListener(new SelectionAdapter() {...});
Button btnPrev = new Button(cmpHeader, SWT.NONE);
btnPrev.setLayoutData(new GridData(SWT.CENTER, SWT.CENTER, false, false, 1, 1));
btnPrev.setText("Prev");
btnPrev.addSelectionListener(new SelectionAdapter() {...});
Label lblNewLabel = new Label(cmpHeader, SWT.NONE);
lblNewLabel.setEnabled(false);
lblNewLabel.setLayoutData(new GridData(SWT.FILL, SWT.CENTER, true, false, 1, 1));
lblBook = new Label(cmpHeader, SWT.BORDER);
lblBook.setText("Book");
lblBook.setLayoutData(new GridData(SWT.RIGHT, SWT.CENTER, false, false, 1, 1));
lblChapter = new Label(cmpHeader, SWT.BORDER);
lblChapter.setLayoutData(new GridData(SWT.CENTER, SWT.CENTER, false, false, 1, 1));
lblChapter.setText("Chapter");
lblScene = new Label(cmpHeader, SWT.BORDER);
lblScene.setText("Scene");
Label lblNewLabel_1 = new Label(cmpHeader, SWT.NONE);
lblNewLabel_1.setEnabled(false);
lblNewLabel_1.setLayoutData(new GridData(SWT.FILL, SWT.CENTER, true, false, 1, 1));
Button btnNext = new Button(cmpHeader, SWT.NONE);
btnNext.setLayoutData(new GridData(SWT.CENTER, SWT.CENTER, false, false, 1, 1));
btnNext.setText("Next");
btnNext.addSelectionListener(new SelectionAdapter() {...});
Button btnSNext = new Button(cmpHeader, SWT.NONE);
btnSNext.setLayoutData(new GridData(SWT.CENTER, SWT.CENTER, false, false, 1, 1));
btnSNext.setText("SNext");
btnSNext.addSelectionListener(new SelectionAdapter() {...});
Composite composite_1 = new Composite(parent, SWT.NONE);
...
and later:
...
lblScene.setText(scene.getTitle());
lblChapter.setText(scene.getChapter().getTitle());
lblBook.setText(scene.getChapter().getBook().getTitle());
cmpHeader.pack(true);
...
Immediately after "cmpHeader.pack(true);" I have the header resized to minimum (ignoring SWT.FILL) as in the first image.
If I resize the window everything snaps back to normal (see second image).
What am I doing wrong?
Regards
Mauro
