Hello,
I have new problem in my application.
I have ViewPart, and inside this viewPart i need to add GraphicalViewer that
will hold some objects from the model. I have model, EditPart and in
createControle(Composite parent) method of the ViewPart i initialize
graphicalView.
public void createPartControl(Composite parent) {
graphicalViewer = new ScrollingGraphicalViewer();
controlViewer = (FigureCanvas)graphicalViewer.createControl(parent);
ScalableFreeformRootEditPart root = new ScalableFreeformRootEditPart();
graphicalViewer.setRootEditPart(root);
graphicalViewer.setEditDomain(new EditDomain());
graphicalViewer.setEditPartFactory(new MeasureItemsEditPartFactory());
graphicalViewer.setContents(device);
ContextMenuProvider cmProvider = new ViewerContextMenu(graphicalViewer);
graphicalViewer.setContextMenu(cmProvider);
getSite().registerContextMenu(cmProvider, graphicalViewer);
}
And it looks ok. I have my own layout, and components are laid out properly,
EditPart is expanding correctly. I have FreeFormlayer as IFigure in the
EditPart.
But, if i have ViewPart with FormToolKit and TableWrapLayout then
GraphicalViewer is unable to expand, and layout is not working as expected.
This is the source for initializing ViewPart. There is FormToolkit with two
composites and TableWrapLayout. GraphicalViewer will createControl on right
composite. This is not working correctly. If i do
graphicalViewer.createControl(parent) it works ok. I suppose it is
TableWrapLayout that casues the problem,.
public void createPartControl(Composite parent) {
toolkit = new FormToolkit(parent.getDisplay());
form = toolkit.createScrolledForm(parent);
TableWrapLayout layout = new TableWrapLayout();
layout.numColumns = 2;
leftData = new TableWrapData();
rightData = new TableWrapData(TableWrapData.CENTER);
form.getBody().setLayout(layout);
leftSection = toolkit.createSection(form.getBody(),Section.TITLE_BAR |
Section.DESCRIPTION);
leftSection.setText(ResourceManager.getInstance().getString( "Category.descri
ptionTitle"));
leftSection.setLayoutData(new TableWrapData(TableWrapData.FILL));
rightSection = toolkit.createSection(form.getBody(),Section.TITLE_BAR);
rightSection.setText(ResourceManager.getInstance().getString ( "Category.viewT
itle"));
TableWrapData rightSectionData = new
TableWrapData(TableWrapData.FILL_GRAB);
rightSectionData.grabHorizontal = true;
rightSection.setLayoutData(rightSectionData);
leftExpandableComposite =
toolkit.createExpandableComposite(form.getBody(),ExpandableC omposite.CLIENT_
INDENT | ExpandableComposite.TITLE_BAR | ExpandableComposite.EXPANDED);
leftExpandableComposite.setLayoutData(leftData);
leftComposite = toolkit.createComposite(leftExpandableComposite,
SWT.NULL);
TableWrapLayout leftTableLayout = new TableWrapLayout();
leftTableLayout.numColumns = 1;
leftTableLayout.bottomMargin = 40;
leftComposite.setLayout(leftTableLayout);
leftComposite.setLayoutData(leftData);
leftExpandableComposite.setClient(leftComposite);
leftExpandableComposite.addExpansionListener(new ExpansionAdapter() {
public void expansionStateChanged(ExpansionEvent e) {
form.reflow(true);
}
});
Label blankLabel = toolkit.createLabel(leftComposite,"");
blankLabel.setImage(ResourceManager.getInstance().getImage("images/blank.bmp
"));
description = toolkit.createLabel(leftComposite,"", SWT.WRAP);
TableWrapLayout rightLayout = new TableWrapLayout();
rightLayout.numColumns = 1;
rightComposite = toolkit.createComposite(form.getBody(), SWT.CENTER);
rightComposite.setLayout(rightLayout);
rightComposite.setLayoutData(rightData);
graphicalViewer = new ScrollingGraphicalViewer();
ScalableRootEditPart root = new ScalableRootEditPart();
graphicalViewer.setRootEditPart(root);
graphicalViewer.createControl(rightComposite);
graphicalViewer.setKeyHandler(new
GraphicalViewerKeyHandler(graphicalViewer));
graphicalViewer.setEditPartFactory(new ScadaEditPartFactory());
ContextMenuProvider cmProvider = new ViewerContextMenu(graphicalViewer);
graphicalViewer.setContextMenu(cmProvider);
getSite().registerContextMenu(cmProvider, graphicalViewer);
root.setViewer(graphicalViewer);
Hyperlink link = toolkit.createHyperlink(leftComposite, "Standard mode",
SWT.WRAP);
link.setBackground(leftComposite.getBackground());
link.setLayoutData(new TableWrapData());
link.addListener(SWT.MouseUp, new
DeviceViewModeListener(DeviceViewModeListener.STANDARD_MODE,
graphicalViewer));
link = toolkit.createHyperlink(leftComposite, "Short mode", SWT.WRAP);
link.setBackground(leftComposite.getBackground());
link.setLayoutData(new TableWrapData());
link.addListener(SWT.MouseUp, new
DeviceViewModeListener(DeviceViewModeListener.SHORT_MODE, graphicalViewer));
}

(in case someone is interested)
I managed to solve my problem. I do this to the rightComposite:
rightComposite.setLayout(new FillLayout(SWT.NULL))
rightComposite.setLayoutData(new TableWrapData(TableWrapData.FILL));
and now it works ok
