source: trunk/Cocoa/Pester/Source/NJRHotKeyManager.m@ 355

Last change on this file since 355 was 355, checked in by Nicholas Riley, 15 years ago

English.lproj/MainMenu.nib: Modernize menu and alarm set dialog
layout. Use keyed archiving (10.2+) nib format.

Info-Pester.plist: Moved from old PBX project.

NJRFSObjectSelector.m: Bug fixes from code sent to Joey: remove
incorrect usage of tryToPerform:with:; fix logic error in menu
construction. Work around Cocoa's deciding that the menu font size
needs adjustment when it doesn't - so the menu font size now matches
the button font size, though the position is still off. Don't pop up
a menu if we're disabled. Use IconRefs for menu icons, though not
(yet) for the button icon.

NJRHistoryTrackingComboBox.m: Remove item height adjustment
workaround; it now makes the items too tall.

NJRHotKey.m: Add a missing [super dealloc] caught by current GCC.

NJRHotKeyField.m: Add a missing [super dealloc] caught by current GCC.

NJRHotKeyManager.m: Add a missing [super dealloc] caught by current
GCC.

NJRIntervalField.m: Fix some type errors.

NJRQTMediaPopUpButton.m: Replace SoundFileManager SPI usage, which
doesn't work in Leopard anyway, with manual enumeration of system
sounds. Start migration to QTKit. Use IconRefs for menu icons.

NJRReadMeController.m: Change source encoding to UTF-8.

NJRSoundManager.m: Fix a type error.

NJRVoicePopUpButton.m: Change source encoding to UTF-8.

NSMenuItem-NJRExtensions.[hm]: Code from ICeCoffEE to use IconRefs for
menu item icons.

PSAlarm.m: Change source encoding to UTF-8.

PSAlarms.m: Fix a signedness mismatch.

PSAlarmsController.m: Change source encoding to UTF-8.

PSAlarmSetController.m: Set keyboard focus after unchecking "Do
script:" and "Play" checkboxes.

PSAlerts.m: Add a missing [super dealloc] caught by current GCC. Fix
a memory leak in property list serialization.

PSPowerManager.[hm]: There's now API for scheduling wakeups; use it
(the old code asserted on startup). To fix: removing scheduled
wakeup. Fix a small type-checking error.

PSPreferencesController.m: Add a missing [super dealloc] caught by
current GCC.

PSScriptAlert.m: Change source encoding to UTF-8.

PSTimeDateEditor.m: Fix a tiny, and one-time, memory leak.

PSTimer.m: Update for new PSPowerManager API.

Pester.pbproj: Deleted; now supporting OS X 10.4+ (up from 10.1,
aiee.)

Pester.xcodeproj: Xcode 2.4+ project, upgraded targets, etc.

SoundFileManager.h: Deleted; this SPI no longer exists in Leopard and
possibly earlier.
