Hi, "Qt via wd" is stunningly impressive! The demos all execute fine, package manager now works via the menu. Windows 7 Enterprise, SP1, 64bit. Arranging screen elements via bins certainly is superior to xywh, reminding me of my \TeX-days when \TeX\ knew best how to "break paragraphs into lines." How can the myriads of Qt-commands be accessed? I tried, for instance, to change the caption of a tab subsequently (script addons\ide\qt\demo\tabs.ijs). Any hint on how this can be accomplished? Cheers---Christoph
