SWT OLE and PowerPoint- Control Order Matters? [message #535309] Sat, 22 May 2010 03:25 Go to next message

I have an embedded OLE widget in my SWT app. When I add another control (i.e. a button) after it, things show OK. However, when I add the control before the OLE widget, the PowerPoint content is not show. Below is the example code with the 'addBefore' flag. This requires a dummy PowerPoint file stub.pptx in 'user.home'. I have searched a bunch but have not found anything. Any suggestions?

import java.io.File;
import org.eclipse.swt.SWT;
import org.eclipse.swt.SWTError;
import org.eclipse.swt.layout.FillLayout;
import org.eclipse.swt.ole.win32.OLE;
import org.eclipse.swt.ole.win32.OleClientSite;
import org.eclipse.swt.ole.win32.OleFrame;
import org.eclipse.swt.widgets.Button;
import org.eclipse.swt.widgets.Composite;
import org.eclipse.swt.widgets.Display;
import org.eclipse.swt.widgets.Shell;

public class Snippet263D {

public static void main(String[] args) {
boolean addBefore = false;
OleClientSite clientSite;
OleFrame oleFrame;
Display display = new Display();
final Shell shell = new Shell(display);
shell.setText("PowerPoint Example");
shell.setLayout(new FillLayout());
Composite panel = new Composite(shell, SWT.BORDER);
FillLayout layout = new FillLayout();
panel.setLayout(layout);
Button bb = null;
if (addBefore)
bb = new Button(panel, SWT.PUSH);
try {
oleFrame = new OleFrame(panel, SWT.NONE);
String home = System.getProperty("user.home");
File fileBeingEdited = new File(home + "/stub.pptx");
clientSite = new OleClientSite(oleFrame, SWT.NONE, fileBeingEdited);
clientSite.doVerb(OLE.OLEIVERB_INPLACEACTIVATE);
} catch (SWTError e) {
e.printStackTrace();
display.dispose();
return;
}
if (! addBefore)
bb = new Button(panel, SWT.PUSH);
bb.setText("Widget 2");
shell.setSize(800, 600);
shell.open();
while (!shell.isDisposed()) {
if (!display.readAndDispatch())
display.sleep();
}
display.dispose();
}
}

The content is showing but since the ole is not the focused one hence ole toolbara nd status dont show......(in case of button true)

click on the ole and see

Because I Choose To.

Vijay,
Many thanks.
I added a setFocus() and things appear without the need to click in the area.
i.e.
. . .
shell.open();
oleFrame.setFocus();
while (!shell.isDisposed()) {
. . .
