[Pharo-project] About UITheme, Widgets and coupling

by StÃ©phane Ducasse

Hi guys we got rid of preferences as a ugly facade and now we have UITheme and UIManager. I would like to understand how we can skin widgets while be as loosely coupled as possible. May be a UI builder is missingâ¦. I was looking at SystemProgressMorph we setDefaultParameters self theme setSystemProgressMorphDefaultParameters: self updateColor "update the apareance of aMorph" self theme preferGradientFill ifFalse: [^ self]. self fillStyle: (self theme progressFillStyleFor: self) and SystemProgressBarMorph has initialize "Initialize the receiver from the current theme." super initialize. barSize := 0. self fillStyle: ( self theme progressBarFillStyleFor: self); borderStyle: (self theme progressBarBorderStyleFor: self); barFillStyle: ( self theme progressBarProgressFillStyleFor: self) extent: aPoint "Update the bar fillStyle if appropriate." super extent: aPoint. self fillStyle isOrientedFill ifTrue: [ self fillStyle: (self theme progressBarFillStyleFor: self)]. self barFillStyle isOrientedFill ifTrue: [ self barFillStyle: ( self theme progressBarProgressFillStyleFor: self)] So to help me understanding the problem, I thought about the flow of things. I would really to avoid to have - widgets construction code in UITheme and UImanager (ref to debugger UI as mentioned by henryk) - UITheme invocation inside the widgets. May be a widget should have its own state and when we build it the class creation only push the info from the UITheme to the widgets What do you think? Stef

In january we will brand our VM and build VM tests. We should improve on that and we should be more to work there and not only igor. Stef

Then, the VMMaker package version says nothing, because to buiyld the VM you need more packages than VMMaker, so you have to guess which version to use. Moreoever, there is also ANOTHER version in VM which is VMMaker class>>versionString which is different from that. Then from the image or from a log we get: VM: Mac OS - intel - 1068 - Croquet Closure Cog VM [CoInterpreter VMMaker.oscog-eem.78] Croquet Cog 3.0.0 so where it is the svn version? So...all in all, I think that indeed, it is quite a mess. But it is also complicated to manage and I don't really know what to suggest. With ConfigurationOfCog at least with one number we group all image side related packages. Then we only need svn/git version. Moreover, we can store this svn/git as the description in each version of ConfigurationOfCog. That way, you know *exactly* what do you need.
