GetSystemPaletteUse function

Applies to: desktop apps only

The GetSystemPaletteUse function retrieves the current state of the system (physical) palette for the specified device context (DC).

Syntax

Copy

UINT GetSystemPaletteUse(
  __in  HDC hdc
);

Parameters

hdc [in]: A handle to the device context.

Return value

If the function succeeds, the return value is the current state of the system palette. This parameter can be one 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.

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 a device supports color palettes by calling the GetDeviceCaps function and specifying the RASTERCAPS constant.
