Change History (most recent first):
|
|
|
|
<18> 7/28/92 DCL Moved applicationFloatKind & systemFloatKind constants out of
|
|
the public eye and into the private Layers header file. At the
|
|
request of TechPubs, and with moral support from Dean, Greg and
|
|
Kenny.
|
|
<17> 8/27/91 JSM Cleanup header.
|
|
<16> 1/3/91 VL (RLC) Add a new public call RedrawAll.
|
|
<15> 9/7/90 DFH Changed SetLayerLock to GetDeskPort
|
|
<14> 7/23/90 EMT Changed IsLayerLocked to WindowType.
|
|
<13> 5/30/90 DC Added interface for GlobalPortRect
|
|
<12> 4/18/90 DC Add a symbolic constant for the dialog centering divisor
|
|
<11> 4/2/90 EMT Added interface for PaintOnePal.
|
|
<10> 3/16/90 DC Added interface for CheckWindow
|
|
<9> 3/14/90 DC Added Error codes for SetWIndowState
|
|
<8> 3/8/90 DC Changed names of some window positioning constants
|
|
<7> 2/27/90 EMT No more AppLayer.
|
|
<5> 2/23/90 HJR Correct Build problem in that type Size is undefined.
|
|
<1> 2/21/90 HJR Moved from Interfaces:CIncludes to Internal.
|
|
<7> 2/20/90 DC Added PositionWindow, AutoPositionWindow, GetWindowState, SetWindowState
|
|
<6> 2/15/90 EMT Changed AuxCtlHndl to AuxCtlHandle to match I.M.
|
|
<5> 2/15/90 JAL Changed AuxWinHndl to AuxWinHandle to match I.M.
|
|
<4> 2/14/90 EMT Moved reserved2 bits here. Made constants for -1 and 0.
|
|
<2> 12/21/89 EMT Changed interfaces to CheckUpdateIn and FrontWindowIn to use
|
|
LayerPtr rather than LayerPeek.
|
|
<1.2> 12/11/89 EMT Added CheckUpdateIn, FrontWindowIn and ActiveWindow.
|
|
<1.1> 12/11/89 EMT Moved layer stuff in Windows.h to here.
|
|
<1.0> 5/15/89 CCH Adding from System project.
