controlling width in UITheme class >> exampleBasicControls

by DougEdmunds

UITheme class >> exampleBasicControls generates 3 columns. I want to control the width of the text entry input area ("Hello") in the left most column In the example, the width depends on the width of the widest text label in that column. If there are no labels, the text input box shrinks to a useless width (about 3-4 typed characters). How can I set the width of the text input field? -- View this message in context: http://forum.world.st/controlling-width-in-UITheme-class-exampleBasicContro… Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.

Re: [Pharo-users] Get "Invalid utf8 input detected" error for a filename

by Juraj Kubelka

For now I am able to fix it by following code: #+BEGIN_SRC Locale current. "a Locale(en)" Latin2Environment class compile: 'fileNameConverterClass ^ISO88592TextConverter'. Locale switchToID: (LocaleID isoLanguage: 'cs'). LanguageEnvironment clearDefault. LanguageEnvironment defaultFileNameConverter. "an ISO88592TextConverter" #+END_SRC It is not perfect, directories with Czech characters is not possible to browse. But I do not mind for now. It is anyway strange, because my operating system environment is cs_CZ.UTF-8. And files are encoded in UTF-8. But FileDirectory>>primLookupEntryIn:index: returns file names in a one byte encoding. It is not valid Latin1 or Latin2. If anyone knows better solution, please let me know. Thanks in advance.

Get "Invalid utf8 input detected" error for a filename

by Juraj Kubelka

Hi, If I try to execute: (FileDirectory on: '/home/jura') directoryNames it says "Invalid utf8 input detected" (UTF8TextConverter>>errorMalformedInput), because of a directory named 'VeÅejnÃ©' ('Å' character is the wrong one). In the file system it is the right. FileDirectory>>primLookupEntryIn:index: returns a wrong ByteString ('Ve?ejnÃ©'). It was tested on Pharo 1.1.1 and Moose 4.3 where I am not able to use a Moose Panel tool because of the problem. Am I able to solve this problem somehow? Set-up something... Thank you in advance, Juraj
