From 3bdbff63fb0c811a2c2a1603ea18ac664882e8aa Mon Sep 17 00:00:00 2001 From: das Date: Tue, 13 Dec 2005 03:44:33 +0000 Subject: * library/demos/cscroll.tcl: add MouseWheel bindings for aqua. * macosx/tkMacOSXCarbonEvents.c (TkMacOSXInitCarbonEvents): * macosx/tkMacOSXMouseEvent.c (TkMacOSXProcessMouseEvent, GenerateMouseWheelEvent): add support for kEventMouseScroll events (smooth mouse wheel scrolling from mighty mouse or scrolling trackpad) by handling kEventMouseWheelMoved on application target as well as on dispatcher, in order to pick up synthesized MouseWheel events from HIObject handler (c.f. QA1453); add support for horizontal scrolling events by generating MouseWheel XEvent with Shift modifier. --- ChangeLog | 15 ++++++++++++++- library/demos/cscroll.tcl | 16 +++++++++++++++- macosx/tkMacOSXCarbonEvents.c | 4 +++- macosx/tkMacOSXMouseEvent.c | 42 +++++++++++++++++++++++++++--------------- 4 files changed, 59 insertions(+), 18 deletions(-) diff --git a/ChangeLog b/ChangeLog index ef1966c..b6bcf52 100644 --- a/ChangeLog +++ b/ChangeLog @@ -1,3 +1,16 @@ +2005-12-13 Daniel Steffen + + * library/demos/cscroll.tcl: add MouseWheel bindings for aqua. + + * macosx/tkMacOSXCarbonEvents.c (TkMacOSXInitCarbonEvents): + * macosx/tkMacOSXMouseEvent.c (TkMacOSXProcessMouseEvent, + GenerateMouseWheelEvent): add support for kEventMouseScroll events + (smooth mouse wheel scrolling from mighty mouse or scrolling trackpad) + by handling kEventMouseWheelMoved on application target as well as on + dispatcher, in order to pick up synthesized MouseWheel events from + HIObject handler (c.f.
