Karl Ramberg uploaded a new version of Morphic to project The Trunk: http://source.squeak.org/trunk/Morphic-kfr.1482.mcz ==================== Summary ==================== Name: Morphic-kfr.1482 Author: kfr Time: 3 March 2019, 12:06:05.575161 pm UUID: 9ff8560d-375c-a947-91b6-3ab0f856f9fc Ancestors: Morphic-ul.1481 Two small fixes from tcj Prevent DockingBar menu item labels from being edited, by default. This hides three possible defects in current item label editing behavior: the editor appears with its position slightly off, it only allows one keypress before automatically accepting the input, and if a menubar icon is shift-clicked then it is erased and replaced by text input by the user. Note that the menubar can be easily restored to its default contents by clicking Extras->Rebuild Menus, or evaluating: TheWorldMainDockingBar updateInstances Copy a method from MVC's ParagraphEditor to Morphic's TextEditor. #printerSetup is sent by StringHolder's shifted yellow button menu and so can be sent to both ParagraphEditor (in MVC) and TextEditor (in Morphic). =============== Diff against Morphic-ul.1481 =============== Item was changed: ----- Method: DockingBarItemMorph>>wantsKeyboardFocusOnShiftClick (in category 'events') ----- wantsKeyboardFocusOnShiftClick "set this preference to false to prevent user editing of docking bar menu items" + ^Preferences valueOfPreference: #allowMenubarItemEditing ifAbsent: [false]! - ^Preferences valueOfPreference: #allowMenubarItemEditing ifAbsent: [true]! Item was added: + ----- Method: TextEditor>>printerSetup (in category 'menu messages') ----- + printerSetup + "copied from ParagraphEditor" + TextPrinter defaultTextPrinter inspect + !
