Is this something that can be corrected via a configuration file (e.g. qtrc)?

I tried the High Contrast style and while I agree that its appearance leaves a lot to be desired, it did seem to remedy matters by presenting larger more visible window/menu controls. That says to me that modifying an existing style might provide a solution to the problem at hand. Perhaps that won't be as modern a solution as a true "it just works" dynamic scaling of these graphical controls, but it will be good enough for me if it allows me to run TDE on laptops such as these at native resolution. Interestingly, one of the things that was not corrected by that style was the really tiny window resizing cursor. I investigated further and noticed that my favorite cursor theme "Xfree theme redglass" now has an annotation "incomplete for TDE" -- I had never noticed that before. I guess the theme is incomplete because it lacks the "redglass" window resizing cursor. Without it, this particular cursor becomes "Adwaita", a theme that apparently doesn't scale at all. I guess I will also have to learn how to "complete" the redglass theme. ------------------------------------------------------- --------------------------------------------------------------------- To unsubscribe, e-mail: trinity-devel-unsubscribe@xxxxxxxxxxxxxxxxxxxxxxxxxx For additional commands, e-mail: trinity-devel-help@xxxxxxxxxxxxxxxxxxxxxxxxxx Read list messages on the web archive: http://trinity-devel.pearsoncomputing.net/ Please remember not to top-post: http://trinity.pearsoncomputing.net/mailing_lists/#top-posting
