Constructor Detail

GtkClipboard

private GtkClipboard(java.lang.String name)

Creates the clipboard and sets the initial contents to the current gtk+ selection.

Method Detail

getClipboardInstance

static GtkClipboard getClipboardInstance()

Returns the one and only GtkClipboard instance for the CLIPBOARD selection.

---

getSelectionInstance

static GtkClipboard getSelectionInstance()

Returns the one and only GtkClipboard instance for the PRIMARY selection.

---

setSystemContents

private void setSystemContents(boolean cleared)

Sets the GtkSelection facade as new contents of the clipboard. Called from gtk+ when another application grabs the clipboard and we loose ownership.

---

setContents

public void setContents(java.awt.datatransfer.Transferable contents,
                        java.awt.datatransfer.ClipboardOwner owner)

Sets the new contents and advertises the available flavors to the gtk+ clipboard.

---

advertiseContent

private void advertiseContent(java.lang.String[] targets,
                              boolean text,
                              boolean images,
                              boolean files)

Advertises new contents to the gtk+ clipboard given a string array of (mime-type) targets. When the boolean flags text, images and/or files are set then gtk+ is asked to also advertise the availability of any text, image or uri/file content types it supports. If targets is null (and all flags false) then the selection has explicitly been erased.

---

provideText

private java.lang.String provideText()

Called by the gtk+ clipboard when an application has requested text. Return a string representing the current clipboard contents or null when no text can be provided.

---

provideImage

private GtkImage provideImage()

Called by the gtk+ clipboard when an application has requested an image. Returns a GtkImage representing the current clipboard contents or null when no image can be provided.

---

provideURIs

private java.lang.String[] provideURIs()

Called by the gtk+ clipboard when an application has requested a uri-list. Return a string array containing the URIs representing the current clipboard contents or null when no URIs can be provided.

---

provideContent

private byte[] provideContent(java.lang.String target)

Called by gtk+ clipboard when an application requests the given target mime-type. Returns a byte array containing the requested data, or null when the contents cannot be provided in the requested target mime-type. Only called after any explicit text, image or file/uri requests have been handled earlier and failed.

---

initNativeState

private static boolean initNativeState(GtkClipboard clipboard,
                                       GtkClipboard selection,
                                       java.lang.String stringTarget,
                                       java.lang.String imageTarget,
                                       java.lang.String filesTarget)
