GetSystemPaletteUse
The GetSystemPaletteUse
function retrieves the current state of the system (physical) palette for the
specified device context.
UINT GetSystemPaletteUse(
|
HDC hdc |
// handle of device
context |
|
); |
|
Parameters
hdc
Identifies
the device context.
Return Values
If the
function succeeds, the return value is the current state of the system palette.
It can be any of the following values:
|
Value |
Meaning |
|
SYSPAL_NOSTATIC |
The system
palette contains no static colors except black and white. |
|
SYSPAL_STATIC |
The system
palette contains static colors that will not change when an application
realizes its logical palette. |
|
SYSPAL_ERROR |
The given
device context is invalid or does not support a color palette. |
To get
extended error information, call GetLastError11C2VS7.
Remarks
By default,
the system palette contains 20 static colors that are not changed when an
application realizes its logical palette. An application can gain access to
most of these colors by calling the SetSystemPaletteUse function.
The device
context identified by the hdc parameter must represent a device that
supports color palettes.
An
application can determine whether or not a device supports color palettes by
calling the GetDeviceCaps function and specifying the RASTERCAPS
constant.
