Re: [Pharo-users] BitArray and BooleanArray ?

by Ben Coman

I don't know the answer but I assume you a looking for a memory efficient way of storing booleans. So perhaps the Bit Field layouts discussed here [1] may be of interest considering the recent introduction of Slots to Pharo. Otherwise I verry vaguely remember Bitmap used for this somewhere. Sorry I can't be more precise.

Spec / GT Inspector integration

by Alistair Grant

If I have a CompositeModel which I want to display as a tab in a GT Inspector, what should the inspector method look like? (I haven't been able to find any examples in the image or on the web) I assume it should be something like: gtInspectEditIn: composite <gtInspectorPresentationOrder: 50> ^ composite spec title: 'Edit'; display: [ :anObject | MyCompositeModelEditor on: anObject ]. But it isn't clear to me what the display block should be returning. I can successfully open the window using: MyCompositeModelEditor new editObject: anObject; openWithSpec. Thanks, Alistair
