See Also:
  - Constant Field Values

### CF_DSPMETAFILEPICT

static final int CF_DSPMETAFILEPICT
Metafile-picture display format associated with a private format. The hMem parameter must be a handle to data that can be displayed in metafile-picture format in lieu of the privately formatted data.

See Also:
  - Constant Field Values

### CF_DSPTEXT

static final int CF_DSPTEXT

### CF_GDIOBJFIRST

static final int CF_GDIOBJFIRST
Start of a range of integer values for application-defined GDI object clipboard formats. The end of the range is CF_GDIOBJLAST.

Handles associated with clipboard formats in this range are not automatically deleted using the GlobalFree function when the clipboard is emptied. Also, when using values in this range, the hMem parameter is not a handle to a GDI object, but is a handle allocated by the GlobalAlloc function with the GMEM_MOVEABLE flag.

See Also:
  - Constant Field Values

### CF_GDIOBJLAST

static final int CF_GDIOBJLAST

See Also:
  - `CF_GDIOBJFIRST`
  - Constant Field Values

### CF_HDROP

static final int CF_HDROP
A handle to type HDROP that identifies a list of files. An application can retrieve information about the files by passing the handle to the DragQueryFile function.

See Also:
  - Constant Field Values

### CF_LOCALE

static final int CF_LOCALE
The data is a handle to the locale identifier associated with text in the clipboard. When you close the clipboard, if it contains CF_TEXT data but no CF_LOCALE data, the system automatically sets the CF_LOCALE format to the current input language. You can use the CF_LOCALE format to associate a different locale with the clipboard text.

An application that pastes text from the clipboard can retrieve this format to determine which character set was used to generate the text.

Note that the clipboard does not support plain text in multiple character sets. To achieve this, use a formatted text data type such as RTF instead.

The system uses the code page associated with CF_LOCALE to implicitly convert from CF_TEXT to CF_UNICODETEXT. Therefore, the correct code page table is used for the conversion.

  - Constant Field Values

### CF_METAFILEPICT

static final int CF_METAFILEPICT
Handle to a metafile picture format as defined by the METAFILEPICT structure. When passing a CF_METAFILEPICT handle by means of DDE, the application responsible for deleting hMem should also free the metafile referred to by the CF_METAFILEPICT handle.

See Also:
  - Constant Field Values

### CF_OEMTEXT

static final int CF_OEMTEXT
Text format containing characters in the OEM character set. Each line ends with a carriage return/linefeed (CR-LF) combination. A null character signals the end of the data.

See Also:
  - Constant Field Values

### CF_OWNERDISPLAY

static final int CF_OWNERDISPLAY
Owner-display format. The clipboard owner must display and update the clipboard viewer window, and receive the WM_ASKCBFORMATNAME, WM_HSCROLLCLIPBOARD, WM_PAINTCLIPBOARD, WM_SIZECLIPBOARD, and WM_VSCROLLCLIPBOARD messages. The hMem parameter must be NULL.

See Also:
  - Constant Field Values

### CF_PALETTE

static final int CF_PALETTE
Handle to a color palette. Whenever an application places data in the clipboard that depends on or assumes a color palette, it should place the palette on the clipboard as well.

If the clipboard contains data in the CF_PALETTE (logical color palette) format, the application should use the SelectPalette and RealizePalette functions to realize (compare) any other data in the clipboard against that logical palette.

When displaying clipboard data, the clipboard always uses as its current palette any object on the clipboard that is in the CF_PALETTE format.

  - Constant Field Values

### CF_PENDATA

static final int CF_PENDATA
Data for the pen extensions to the Microsoft Windows for Pen Computing.

See Also:
  - Constant Field Values

### CF_PRIVATEFIRST

static final int CF_PRIVATEFIRST
Start of a range of integer values for private clipboard formats. The range ends with CF_PRIVATELAST. Handles associated with private clipboard formats are not freed automatically; the clipboard owner must free such handles, typically in response to the WM_DESTROYCLIPBOARD message.

See Also:
  - Constant Field Values

### CF_PRIVATELAST

static final int CF_PRIVATELAST

See Also:
  - `CF_PRIVATEFIRST`
  - Constant Field Values
