I.T. aware

Desktop or Web, which choice ? I asking the question. One of the features that makes the difference is the fullscreen mode. Under IE or Firefox a scroll bar stay on the left. In SWT it’s possible to have a real fullscreen mode and also force the window on top. Underneath you see the code to do that, all you have to do is simply set the style of the Shell to NO_TRIM to remove the border and the default header and ON_TOP to force the window on top of the others (actually i don’t know how i can do that in Web) :
<pre> public class ApplicationWorkbenchWindowAdvisor extends WorkbenchWindowAdvisor { public ApplicationWorkbenchWindowAdvisor(IWorkbenchWindowConfigurer configurer) { super(configurer); } public ActionBarAdvisor createActionBarAdvisor(IActionBarConfigurer configurer) { return new ApplicationActionBarAdvisor(configurer); } public void preWindowOpen() { IWorkbenchWindowConfigurer configurer = getWindowConfigurer(); configurer.setShellStyle(SWT.NO_TRIM | SWT.ON_TOP); configurer.setShowCoolBar(false); configurer.setShowStatusLine(false); configurer.setTitle("Test FullScreen RCP"); } @Override public void createWindowContents(Shell shell) { super.createWindowContents(shell); shell.setMaximized(true); } } </pre>

Like John O’Shea I’ll be not at EclipseCon and i rather be at RAP sessions. The GWT community is very large and continue to grow. Unfortunately others initiative like RAP haven’t the same community yet. I think the energy to develop new components by the community actually is interesting and could be more interesting if these components can be integrate in a AJAX RCP like environnement. What about an integration of GWT with RAP ? I think it’s not easy because of the choice of RWT/innopract but why not.

The Eclipse Nebula sub-project present the Grid widget, an alpha version which works great, i use it in my application to administrate reservation of swimming course. The JFace layer is not implemented yet but it’s on rails. But I don’t know if a GridViewer will be very useful because the needs of a spreadsheet are very large.

This is an example of Grid with header of columns and rows, column grouping, expand/collapse event of group column. The objective is to show the schedules in columns and the week days in rows, each column is composed of 3 sub-columns showing the total capacity, the availability and the sold place. The total capacity column can be desactivated :

public Grid createGrid(List in_schedules, Composite in_composite) {
        // Grid creation
        Grid l_grid = new Grid(in_composite, SWT.BORDER | SWT.H_SCROLL | SWT.V_SCROLL);
        // show column header
        l_grid.setHeaderVisible(true);
        // show row header
        l_grid.setRowHeaderVisible(true);
        // enable cell selection
        l_grid.setCellSelectionEnabled(true);
        GC l_gc = new GC(l_grid);
        // list of swimming course schedules
        for (ScheduleType l_scheduleType : in_schedules) {
            // create column group with dynamic column (TOGGLE)
            GridColumnGroup l_scheduleColumn = new GridColumnGroup(l_grid, SWT.TOGGLE);
            // column group header name
            l_scheduleColumn.setText(l_scheduleType.getLabel());
            final int l_colWidth = l_gc.stringExtent(l_scheduleType.getLabel() + " <<").x + 6;
            // initialize state (collapse)
            l_scheduleColumn.setExpanded(false);
            // listen expand event
            l_scheduleColumn.addListener(SWT.Expand, new Listener() {
                public void handleEvent(Event event) {
                    int l_width = l_colWidth / 3;
                    if (l_width < 20) {
                        l_width = 20;
                    }
                    for (GridColumn l_column : ((GridColumnGroup) event.widget).getColumns()) {
                        l_column.setWidth(l_width);
                    }
                }
            });
            // listen collapse event
            l_scheduleColumn.addListener(SWT.Collapse, new Listener() {
                public void handleEvent(Event event) {
                    int l_width = l_colWidth / 2;
                    if (l_width < 20) {
                        l_width = 20;
                    }
                    for (GridColumn l_column : ((GridColumnGroup) event.widget).getColumns()) {
                        if (l_column.isSummary()) {
                            l_column.setWidth(l_width);
                        }
                    }
                }
            });
            int l_width = l_colWidth / 2;
            if (l_width < 20) {
                l_width = 20;
            }
            // create columns group
            GridColumn l_capacity = new GridColumn(l_scheduleColumn, SWT.CENTER);
            l_capacity.setText("C");
            l_capacity.setWidth(20);
            l_capacity.setCellSelectionEnabled(false);
            // collapsed ? no
            l_capacity.setSummary(false);
            l_capacity = new GridColumn(l_scheduleColumn, SWT.CENTER);
            l_capacity.setText("V");
            l_capacity.setWidth(l_width);
            l_capacity.setCellSelectionEnabled(false);
            // collapsed ? yes
            l_capacity.setSummary(true);
            l_capacity = new GridColumn(l_scheduleColumn, SWT.CENTER);
            l_capacity.setText("L");
            l_capacity.setWidth(l_width);
            l_capacity.setSummary(true);
            l_capacity.setData(l_scheduleType);
        }
        l_gc.dispose();
        //l_grid.pack(true);
        return l_grid;
    }

The Grid binding is realise via the GridItem object

// GridItem creation
l_gridItem = new GridItem(l_grid, SWT.CENTER);
// row header name
l_gridItem.setHeaderText(l_headerText);
// set value by index column
l_gridItem.setText(, );

It possible to merge cell of a same line e.g.:
e.g.:

l_gridItem.setColumnSpan(0, in_grid.getColumnCount());

And to get the selection :

Point[] l_selections = l_grid.getCellSelection();
for (Point l_selection : l_selections) {
	// get GridItem
	l_grid.getItem(l_selection.y);
	// get GridColumn
	l_grid.getColumn(l_selection.x)
}

UI Forms will update, Kim peter have posted screenshots in the bugReport. It should be impemented in the M5 and you can test soon in the org.eclipse.ui.forms.examples. The changes are :

• enhancement of the header (for Vista)
• drop down menu
• drag’n drop title
• tabs on top
• error messages in the header

Mylar is a task management eclipse plugin, the Mylar’s advantage is to associate context on tasks. A statistic show that users spend 75% time navigating in their project, Mylar optimize this by filtering the navigator view on elements (class, methods, resources, …) link to the task. The navigator is dynamically update by investigating the bug. An other important advantage is the integration with bug tracker, actually only bugzilla, jira and trac have been integrated and a generic integration is in dev.
