Keyboard Event Weirdness
I put the following halt in HandMorph>>#handleEvent: anEvent isKeyboard ifTrue: [Transcript show: anEvent printString, ' keyChar: ', anEvent keyCharacter asString, ' keyValue: ', anEvent keyValue asString; cr]. Then I typed 'hi' in a Workspace and hit Cmd+a. Look at the weird Transcript output... [keyDown ''] keyChar: keyValue: 4 [keystroke 'h'] keyChar: h keyValue: 104 [keyUp ''] keyChar: keyValue: 4 [keyDown ''] keyChar: keyValue: 34 [keystroke 'i'] keyChar: i keyValue: 105 [keyUp ''] keyChar: keyValue: 34 [keyDown '<Cmd->'] keyChar: keyValue: 0 [keystroke '<Cmd-a>'] keyChar: a keyValue: 97 [keyUp '<Cmd->'] keyChar: keyValue: 0 It seems the keyUp/Downs do not have the correct charCode and the keyValue is different than the keystroke for the same key.

b.t.w. the position of the events has anInteger for x and aFloat for y. What's up with that? ----- Cheers, Sean -- View this message in context: http://forum.world.st/Keyboard-Event-Weirdness-tp4737056p4737064.html Sent from the Pharo Smalltalk Developers mailing list archive at Nabble.com.

Mac 10.8.5 ----- Cheers, Sean -- View this message in context: http://forum.world.st/Keyboard-Event-Weirdness-tp4737056p4737075.html Sent from the Pharo Smalltalk Developers mailing list archive at Nabble.com.
In the VM code, all three are generated in sequence by the segment below. So, yes, it is an unholy mess. The real key taken inside Pharo is the macRomanCharacter getting translated in the lookupString thing. The KeyDown and KeyUp events are holding the evt.charCode, whatever this happens to be. The file is sqSqueakOSXApplication+events.m in platforms\iOS\vm\OSX My current machine here is a Win8 box and I am on the move, so, no way to test at the moment. NSString *lookupString = [[NSString alloc] initWithCharacters: &unicode length: 1]; [lookupString getBytes: &macRomanCharacter maxLength: 1 usedLength: NULL encoding: NSMacOSRomanStringEncoding options: 0 range: picker remainingRange: NULL]; [lookupString release]; evt.pressCode = EventKeyDown; unsigned short keyCodeRemembered = evt.charCode; evt.utf32Code = 0; evt.reserved1 = 0; evt.windowIndex = (int)[[mainView windowLogic] windowIndex]; [self pushEventToQueue: (sqInputEvent *)&evt]; evt.charCode = macRomanCharacter; evt.pressCode = EventKeyChar; evt.modifiers = evt.modifiers; evt.utf32Code = unicode; [self pushEventToQueue: (sqInputEvent *) &evt]; if (i > 1 || ![mainView lastSeenKeyBoardStrokeDetails]) { evt.pressCode = EventKeyUp; evt.charCode = keyCodeRemembered; evt.utf32Code = 0; [self pushEventToQueue: (sqInputEvent *) &evt]; } I've attached the file so you can see it in its full glory. It is indeed very peculiar Regards, Phil On Wed, Jan 15, 2014 at 9:53 PM, Sean P. DeNigris <sean@clipperadams.com>wrote:

This still has not been fixed. Any ideas? I sent a message to the VM list... ----- Cheers, Sean -- View this message in context: http://forum.world.st/Keyboard-Event-Weirdness-tp4737056p4808969.html Sent from the Pharo Smalltalk Developers mailing list archive at Nabble.com.

Each platform has its own idea about these events. That is where SDL will be welcome. Phil
This still has not been fixed. Any ideas? I sent a message to the VM
list...
