File: PrefsWindow.c
Abstract: Handles all Window related functions for the Demo.
Version: 5.0
Change History:
<5.0> converted everything from a List Manager list interface
to a Data Browser control
renamed RedrawPrefsWindowList to
RedrawPrefsWindowDataBrowser which doesn't actually draw
the data browser but rather just invalidates its content
rectangle
removed handleDrawContent, handleContentClick,
handleKeyDown, createIconList, drawFrameAndFocus, and
changePanel
removed handleActivate and put its necessary
functionality into windowEventHandler
<4.0> removed all Classic code
made AdjustControls, HandleDrawContent, and
HandleActivate, internal functions
made HandleContentClick an internal function and changed
its last parameter from an EventModifiers to a UInt32
made HandleKeyDown an internal function and changed its
first parameter from a char to a UInt32
made ClosePrefsWindow an internal function
adjusted the RunningInMacOSX dependent stuff
changed windowEventHander to call through to the
standard handler for default behavior on activation and
close events instead of implementing it on top of the
custom behavior already implemented
<3.0> converted the Carbon version to use Carbon Events and
standard handlers
added windowEventHandler to support Carbon Events
windowEventHandler has some similarities to handleEvents
in ExamplePrefs.c
Carbon Events has richer support for mouse events, we
support a mouse wheel in Carbon
<2.0> Carbonized
for the Carbon version we're using CreateCustomList to
create the list
introduced some new globals to account for the different
theme metrics between the Platinum and Aqua appearances
<1.0> first release version
this draws a list directly into a window and mimics the
behavior of a list box control
it turns out this was actually quite difficult, there is
a LOT of background color/pattern changing you have to
do to achieve the desired effect
