[Solved] Redraw from LibreOffice Calc extension

[HCL]

I'm developing an extension in Java for Libreoffice Calc.

How to perform redrawing?

It means refresh the view of spreadsheet between executing extension process.

If in VB, DoEvents.

The following Java code has been recorded with the MRI extension using OpenOffice 4.1. I do not fully understand the X,Y arguments to the draw function but it seems to redraw the ContainerWindow.

Code: Select all

import com.sun.star.awt.XView;
import com.sun.star.awt.XWindow;
import com.sun.star.frame.XController;
import com.sun.star.frame.XFrame;
import com.sun.star.frame.XModel;
import com.sun.star.uno.UnoRuntime;
import com.sun.star.uno.XComponentContext;

public static void snippet(XComponentContext xComponentContext, Object oInitialTarget)
{
	XModel xModel = UnoRuntime.queryInterface(
		XModel.class, oInitialTarget);
	XController xController = xModel.getCurrentController();
	
	XFrame xFrame = xController.getFrame();
	
	XWindow xWindow = xFrame.getContainerWindow();
	
	XView xView = UnoRuntime.queryInterface(
		XView.class, xWindow);
	
	xView.draw(0, 0);
	
}

The api documentation for "draw" is here:

https://www.openoffice.org/api/docs/com ... .html#draw

[JeJe]

invalidate and invalidateRect are for repainting a particular window:

Thank you for your reply.

I could perform redrawing

But, when I perform redrawing by below code in for loop repeatedly,
redrawing is performed just first one time.

Code: Select all

	   XModel model = UnoRuntime.queryInterface(XModel.class, target);
	   XController xController = model.getCurrentController();
	   XFrame frame = xController.getFrame();
	   XWindow window = frame.getContainerWindow();
	   XView view = UnoRuntime.queryInterface(XView.class, window);
	   view.draw(0, 0);
