but if I try to do openInWindow instead of openInWorld in the end it turns it to white box , why ?

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

by Nicolai Hess

Don't use fontName: fontName size: fontSize as it only creates StrikeFont font, where the max size is 24 (I think). This works .... font := LogicalFont familyName: 'Open Sans' pointSize: 70. tMorph := StringMorph new. tMorph contents: 'Hello World'; font: font; emphasis: TextEmphasis bold emphasisCode. bMorph := Morph new color: Color red; addMorphBack: tMorph. bMorph bounds:(tMorph fullBounds). bMorph openInHand ... but it seems we have a problem with the free type fonts (again). Since Pharo 40195 I can not select any other fonts in Settings, only Bitmap DejaVu Sans. 2014-09-04 22:04 GMT+02:00 Alexandre Bergel <alexandre.bergel(a)me.com>: > No idea :-) > > Alexandre > -- > _,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;: > Alexandre Bergel http://www.bergel.eu > ^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;._,.;:~^~:;. > > > > On Sep 4, 2014, at 12:18 PM, Tim Mackinnon <tim(a)testit.works> wrote: > > Iâm still curious how you do it in Morphic? > > >

Re: [Pharo-users] Encoding CJK URL?

by Sven Van Caekenberghe

Hi Dirk, Please try: ZnDefaultCharacterEncoder value: ZnUTF8Encoder new during: [ ZnClient new get: 'http://www.hatinosu.net/onsen/import.kml'; yourself ]. ZnDefaultCharacterEncoder value: ZnUTF8Encoder new during: [ 'http://www.hatinosu.net/onsen/import.kml'asZnUrl retrieveContents ]. The mime-type/content-type of the response, application/vnd.google-earth.kml+xml, does not (directly/automatically) specify the encoding to use (as in charset=utf-8), which result in a ZnNullEncoder being used. HTH, Sven PS: I also assume you are using a Unicode font with the necessary glyphs.

Encoding CJK URL?

by Wowerat Dirk

My code to download some UTF8 text with japanese kanji from an url: url := 'http://www.hatinosu.net/onsen/import.kml' asZnUrl. url_string := url retrieveContents. url_string class. ByteString Now the japanese parts of url_string are unreadable. What I need is WidString and not ByteString. On linux I "solved" the problem with this workaround. download := 'wget -O /tmp/file.tmp "http://www.hatinosu.net/onsen/import.kml"'. OSProcess thisOSProcess waitForCommand: download. fs := FileStream fileNamed: '/tmp/file.tmp'. string := fs contents. fs close. string class. WideString How do I do this without extern programms?
