[Pharo-project] Athens work in progress: couple screenshots

by Igor Stasenko

Stephane, asked me to show this :) Nothing fancy there, just a same window, rendered with different scale. The code which doing this, is following: testWindowRender | surf | surf := AthensBalloonSurface new form: (Form extent: Display extent depth: 32). surf drawDuring: [ :canvas | canvas pathTransform scaleBy: 0.5. " or 2 " canvas fullDrawMorph: self testWindow. ]. Display getCanvas translucentImage: surf form at: 0@0 There are problems of course: - i have to use different Paragraph class, and therefore i have to use different TextMorph subclass, because otherwise it will use hardcoded Paragraph class. The paragraph model is a bit messy. It doesn't clear to me, what role it has. I thinking that it is a cached state for Text, to draw it on screen. But apparently it is more than a cache , and there are couple things which simply don't fit with it. I am thinking about doing some overhaul with TextMorph/Paragraph later, to clean up unused stuff (believe me there's a lot of it), and to make clear separation of roles. In fact, this stuff could live by itself. You can render text without using paragraph(s) mess. But i want to integrate that with Morphic, so we can switch to Athens at some point. That's why i need to deal with this. :) -- Best regards, Igor Stasenko.

Re: [Pharo-project] Font lookup using styleName?

by Igor Stasenko

i'm not sure , but i think currently you have to create an instance of logical font, and then set it's emphasis i.e bold/italic etc. On 22 November 2011 09:19, StÃ©phane Ducasse <stephane.ducasse(a)inria.fr> wrote: > > On Nov 21, 2011, at 9:15 PM, Bernhard Pieber wrote: > >> Hi everyone, >> >> I am using Pharo 1.3 and I am quite a newbie when it comes to Pharo so please be kindâ¦ > > we always are :) > Seriously in fact :) > >> >> I saw in the font chooser that Pharo supports font families with multiple styles.

[Pharo-project] Font lookup using styleName?

by Bernhard Pieber

Hi everyone, I am using Pharo 1.3 and I am quite a newbie when it comes to Pharo so please be kind... I saw in the font chooser that Pharo supports font families with multiple styles. On my Mac for instance the font family Helvetica has the styles Light, Light Oblique, Regular, Oblique, Bold, and Bold Oblique. In the code font families are subinstances of FontFamilyAbstract and styles are subinstances of FontFamilyMemberAbstract. However, for creating fonts programmatically there seems to be no message which takes the style into account. There is LogicalFont class>>#familyName:pointSize:. How do I know which of the styles this uses? Then there is LogicalFont class>>#familyName:fallbackFamilyNames:pointSize:stretchValue:weightValue:slantValue:. How should I know which parameters I have to pass in to get a certain style? I would have expected a method like #familyName:styleName:pointSize: but I did not find one. Any idea why? Is this an omission or a feature? Cheers, Bernhard
