Thanks :-) So, if I have the following code in a message: ============================================ saveToFile "Saves the current tree to a file" | file writeStream markdownFile | file := UITheme builder fileSave: 'Guardar archivo como...' extensions: #('ston') path: nil. file ifNil: [ self inform: 'Exportación cancelada'. ^ self ]. writeStream := file writeStream. workingFile := writeStream name asFileReference. markdownFile := (workingFile parent) / (workingFile basenameWithoutExtension, '.markdown'). [ self exportAsSton: mainTree on: writeStream. self exportAsMarkdown: mainTree on: markdownFile ] ensure: [ writeStream ifNotNil: #close ]. browser update. ============================================ and I use the saveToFile message to rename the current file, and that name is showed in the title of a GT browser window, the name should change with the last line (browser update)? If that is not intended behaviour, how can I change the title of a GT browser window if this is taken from a file name that is saved (inside Moose) with a different name?
