Re: [Pharo-users] How to create a red box with text in a big font?

by PBKResearch

Hello I have played with this on Moose 5.0 (Pharo 3.0 update: #30854) on Windows 7 Pro. For me, it is necessary to include color:Color red after openInWindow to get the red background, as Thierry said. There is another puzzle, which is that the code does not respond in any linear way to changes in the font size. If you replace size: 75 with any number from 38 upwards, you get the same size of font. Change the size to 37 and there is a sharp reduction in size, and it changes in proportion for smaller numbers. Is there something different about this font?

Font scale properly on my home machine in 3.0, doesn't scale on my work machine on 3.0, scale on my work machine in 4.0. Both machines are Ubuntu 14.04 AMD64 and Pharo has the same settings on both (Freetype and all). Thierry

You can try that by right-clicking on the virtual machine application, selecting "Get Info" and checking "Open in low resolution". See if that improves the situation for you until the problem is addressed on a higher level. Tommaso

I am a Glorp user, but not on Pharo, and I am very much interested in problems people might find or - more interestingly - solve with Glorp. From my experience with using Glorp on VA Smalltalk, it is sometimes very hard to tell if you have a general Glorp problem or some porting error in front of you. So I would say the primary group for Glorp questions should be the Glorp google group (see your link above). Another argument: if we followed your advice for every library/tool/framework, wouldn't this pollute the Pharo Mailing list?
