Methods

• TreeDragDest (Handle = null)

  Creates a new TreeDragDest by wrapping a native handle or another wrapper.

  • @p Handle is the native handle or another wrapper whose handle to adopt.

• toNativeHandle (Source)

  Normalizes a constructor argument into a raw pointer carrier. Accepts a raw NativeHandle, a raw NativeBuffer returned from fn.call(...), another generated wrapper exposing handle(), or null. Returns null when the argument carries no pointer.

  • @p Source is the raw handle, raw buffer, wrapper, or null.
  • @r A raw pointer carrier or null when no pointer is present.

• getLib ()

  Returns the opened native library for this generated wrapper.

  • @r The opened native library.

• handle ()

  Returns the wrapped NativeHandle.

  • @r The wrapped NativeHandle.

• isNull ()

  Returns true when the wrapped handle is null.

  • @r A bool.

• describe ()

  Returns a small string for debugging generated wrappers.

  • @r A string.

• drag_data_received (object dest, object value)

  Asks the GtkTreeDragDest to insert a row before the path @dest, deriving the contents of the row from @value. If @dest is outside the tree so that inserting before it is impossible, %FALSE will be returned. Also, %FALSE may be returned if the new row is not created for some model-specific reason. Should robustly handle a @dest no longer found in the model!

  • @p dest is row to drop in front of.
  • @p value is data to drop.

• row_drop_possible (object dest_path, object value)

  Determines whether a drop is possible before the given @dest_path, at the same depth as @dest_path. i.e., can we drop the data in @value at that location. @dest_path does not have to exist; the return value will almost certainly be %FALSE if the parent of @dest_path doesn’t exist, though.

  • @p dest_path is destination row.
  • @p value is the data being dropped.
