Summary | 0006514: Turning on showEvents triggers a DNU error | |||||||||||
Description |
In 3.10 and 3.9, doing HandMorph showEvents: true throws up a MNU: UndefinedObject(Object)>>doesNotUnderstand: #+ Receiver: nil Arguments and temporary variables: aMessage: + 15 Receiver's instance variables: nil Point>>+ Receiver: 0@nil Arguments and temporary variables: arg: 0@15 Receiver's instance variables: x: 0 y: nil HandMorph>>handleEvent: Receiver: a HandMorph(3728) Arguments and temporary variables: anEvent: [411@467 mouseUp 30913] evt: [411@467 mouseUp 30913] ofs: nil |
|||||||||||
Additional Information | MNU is triggered by nil value for ofs at the second check for ShowEvents. ShowEvents is checked in the beginning and in the end. ofs is computed only in the first block. ofs needs to be recomputed in each block because handleEvents makes blocking calls in between and ShowEvents could be set to true meanwhile. The attached cs recomputes ofs in each block. | |||||||||||
