He said a while back that:

DisplayScreen>>newDepthNoRestore:

• delegation to UIManager, MorphicUIManager implementation should be added

What I think that means is this:

• moving DisplayScreen >> #newDepth: to UIManager >> #newDepth:
• changing "Display newDepth: foo" to "UIManager default newDepth: foo"
• adding UIManager >> newDepthNoRestore: as a self subclassResponsibility
• changing any "Display newDepthNoRestore: foo" occurrences
• moving DisplayScreen >> #newDepthNoRestore to MorphicUIManager >>

#newDepthNoRestore:

• copying most of MorphicUIManager >> #newDepthNoRestore: to

MVCUIManager or whatever it's called ("most" means "everything outside a Smalltalk isMorphic ifTrue: []")

This

• delegates setting screen depth to the UIManager, and
• avoids making Graphics depend on ToolBuilder-Kernel (because TBK

already depends on Graphics (because of a probably removable test case thing))

The assumption here is that Graphics is lower level/more fundamental than TBK.

Thoughts?

Hi Frank,

This assumption seems eminently reasonable to me. Smalltalk has long been focused on providing a direct graphical representation of the system to the user. This says to me then that, before we can make tools for the system, we need a way of representing them onscreen. So having Graphics be lower level than TBK makes sense when I come at it from that angle.

Thanks for your great work, Jeff

Sounds sensible to me. a tool builder either depends upon having Graphics with which to build the tool, or some other mechanism that is independent of Graphics (say, ExternalHostGraphicsForWayland).
