Launching OSWindow windows when in headless mode

by kmo

I would like to launch my application main morph in an OS Window from a pharo image run in headless mode from the command line. But this just gives me a libSDL2 not found error. I'm using pharo 6 on linux. Is it possible to use OSWindow to open windows from a headless image? I want my main application window to be an OS window rather than the pharo application window. The big advantage of doing this (on linux at least) is that you have control over the title and size of the window. It is not possible to set the size and title of the pharo application image window in linux because of bugs. I thought launching my app in an OS Window might be a good workaround but it doesn't seem to work. -- View this message in context: http://forum.world.st/Launching-OSWindow-windows-when-in-headless-mode-tp49… Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Re: [Pharo-users] Japanese Fonts

by tesonep＠gmail.com

Hi, which version of Pharo are you using? Where do you install your font in your linux system? This is because Pharo is looking for the fonts in the paths '/usr/share/fonts' '/usr/local/share/fonts' and ~/.fonts. So maybe it is not finding them. This is not the ideal solution, because if you have another font directory configured you can't use it (even though, adding your custom directory is as easy as modifying a method :) ). Have you tried to disable and reenable FreeType support in the settings browser. It will help as when freetype is enabled the font cache is reconstructed. Also you can try to set the font from that settings browser. If it is shown in the font dialog when using the system browser you can use the font. Cheers, Pablo.

Japanese Fonts

by Evan Donahue

Hello, I am trying to get Japanese characters to show up in my Pharo image. Following some advice I found on google, I have set my font to something that I think should handle Japanese characters: defaultFont := LogicalFont familyName: 'Droid Sans Fallback' pointSize: 18. StandardFonts defaultFont: defaultFont. I then used the settings browser to force that to all system fonts. I did not notice a change to any of the text when I did this, so I am not sure it worked. Also, Japanese text still shows up as spaces. Does anyone know whether this is something I need to deal with in Pharo, on Ubuntu, or both? As far as I can tell, the font is on my system. Thanks, Evan

You can use WarpBlt to scale the form. | input output | input := Smalltalk ui icons iconNamed: #class. output := Form extent: 128 asPoint depth: 32. (WarpBlt toForm: output) sourceForm: input; cellSize: 1; combinationRule: Form over; copyQuad: input boundingBox innerCorners toRect: (0 asPoint extent: 127 asPoint). output writePNGFileNamed: 'somefile.png' Best regards, Henrik From: Pharo-users [mailto:pharo-users-bounces@lists.pharo.org] On Behalf Of Trussardi Dario Romano Sent: Thursday, December 22, 2016 6:45 PM To: Any question about pharo is welcome <pharo-users(a)lists.pharo.org> Subject: Re: [Pharo-users] Scaled image Ciao, Morphs have an extent method that you can passes the size as a point in the x@y format, there are also width: and height: methods that take simple numbers Can explain what i need do with some code, example ?

Re: [Pharo-users] Modeling a join table

by sergio ruiz

Are you going to use relational database to store this data? Or you goint to use image saving / object-oriented DB for persistence? iâd like to use voyage.. so i can use MongoDB for persistence.. 1) Are there strong asymmetry in queries? Which kind of queries are more frequent: "give me tags of this radio" or "give me radios with this tag"? i would say that at the end of the day, it is going to be about the same.. lots and lots of each call.. 2) Do you need to store other information EXCEPT fact that that radio is marked by this tag? For example, do you need to store the time tag was assigned to the station or the user who have assigned it? You got the idea, I believe. i am going to guess that there will be more information on this.. as in.. who created the tag.. so i can import JUST that userâs tags for their list.. while maintaining a set of tags as default tags.. 3) Are queries simple "stations with tag X" / "tags of station X", or they may often looks like "stations with tag A or B, but not both" or something even more complicated. queries will simply be.. give me all stations with this tag.. Â or these tags.. thanks! ---- peace, sergio photographer, journalist, visionary Public Key:Â http://bit.ly/29z9fG0 #BitMessageÂ BM-NBaswViL21xqgg9STRJjaJaUoyiNe2dV http://www.Village-Buzz.com http://www.ThoseOptimizeGuys.com http://www.coffee-black.com http://www.painlessfrugality.com http://www.twitter.com/sergio_101 http://www.facebook.com/sergio101

You can, but you might not want to. Scaling images is rather slow, you often want an external process for that, especially if you want to operate from disk to disk. You do not want to block your image too long, and you might want to have your front-end web server serve those logo's instead of your smalltalk image. ImageMagick can be useful there. Stephan
