http://source.squeak.org/trunk/Morphic-mt.1724.mcz ==================== Summary ==================== Name: Morphic-mt.1724 Author: mt Time: 20 February 2021, 12:46:52.542759 pm UUID: 635e4922-d576-8b43-b47e-6529b967d1a4 Ancestors: Morphic-mt.1723 Extracts gridding from PasteUpMorph as new layout policy: GridLayout -- so that it is available to any morph. - Adjust drag implementation in resizer-grips and splitters to be relative to the mouse-down position to make gridding feel better - Adds "self disableLayout: true" to avoid gridding in overlay morphs such as dialogs, flaps, balloons, menus - Adds new preference(s) for enabling the project world's grid - Inst var "griddingOn" no longer needed in PasteUpMorph - Removes all those scattered "gridPoint:" calls bc. layout policy takes care of that now - Some code clean-up in table-layout properties - Documents an interesting bug in HandMorph >> #handleEvent:, which is not caused by this change =============== Diff against Morphic-mt.1723 =============== Item was changed: ----- Method: AbstractResizerMorph>>mouseDown: (in category 'event handling') ----- mouseDown: anEvent + self referencePoint: anEvent position - self position.! - self referencePoint: anEvent position.!
