Basically yes, although some of the internal aspects could be improved. Largely has to do with the way we sort of had to retrofit it onto Tweak. Michael

Automatically selecting the text pane violates basic UI principles. In many cases this is not what you want, e.g. when you just browse existing code. 2. I don't see why not pre-selecting the template helps? I've quickly changed that, but clicking on it doesn't select it. However, whatever focus settings you've enabled in your Pharo image, double clicking onto the text pane selects everything. Lukas -- Lukas Renggli www.lukas-renggli.ch

I've integrated you changes, but I had to change many things because your styles broke the layout of the two columns and the position of the separation bar between them.

I was meaning caching for UI widget rendering. Of course, in DrGeo it does not make sense, but I was not thinking at all to it. I remember you were using XUL for UI definition in Sophie, why this choice? Hilaire

You have to be careful though with caching, as you might end up copying a lot of bits around even if caching doesn't really make sense for your particular application. IIRC (it's been a while) in Tweak you first draw to the cache, then the cache is drawn to the Squeak Display bitmap and then that is drawn to the screen. No great when you are playing e.g. a video.

Yes, vector based UI is where we should move to keep in the course. Is it what you did for Sophie? If so, did you use some bitmap caching technic?

Is it correct to say a well integrated Rome Cairo framework in Moprhic could simplify the whole graphic framework of the system. Will it allow us to have vector based UI element or is non sense?
