Hi guys, I have a problem with the placement of my gwindow widget. When I start the gwindow widget it is displayed near the middle of my screen but I want that the widget is on the upper left side of my screen. Is it possible to define where my gwindow pops up? And additionally, I want to focus my gwindow permenantly. Is that possible, too Thanks, Norwege...

I want to assign a default handler to a toolbar button and change the handler later.

What's the best object browser? Dear all, I have tried all the popular R IDE or editors like Eclipse, Komodo, JGR, Revolution... They all have fancy fucntions like auto completion, syntax highlight.... BUT, I JUST WANT A OBJECT BROWSER! The easiest way to view objects in R console is fix(), but you have no global view of all the objects in the workspace. Revolution has the best object

There's not necessarily a logical stopping point, so I usually use ctrl-C when I'm done to stop it. I've made a gWidgets interface to the function that gets some user info and then on a
