FLTK global copy/cut/paste functions declared in <FL/Fl.H>
|
static |
FLTK will call the registered callback whenever there is a change to the selection buffer or the clipboard.
The source argument indicates which of the two has changed. Only changes by other applications are reported.
|
static |
Copies the data pointed to by stuff
to the selection buffer (destination
is 0) or the clipboard (destination
is 1); len
is the number of relevant bytes in stuff
.
The selection buffer is used for middle-mouse pastes and for drag-and-drop selections. The clipboard is used for traditional copy/cut/paste operations.
|
static |
Initiate a Drag And Drop operation.
The selection buffer should be filled with relevant data before calling this method. FLTK will then initiate the system wide drag and drop handling. Dropped data will be marked as text.
Create a selection first using: Fl::copy(const char *stuff, int len, 0)
|
static |
Pastes the data from the selection buffer (source
is 0) or the clipboard (source
is 1) into receiver
.
Set things up so the receiver widget will be called with an FL_PASTE event some time in the future with the data from the specified source
in Fl::event_text() and the number of characters in Fl::event_length(). The receiver should be prepared to be called directly by this, or for it to happen later, or possibly not at all. This allows the window system to take as long as necessary to retrieve the paste buffer (or even to screw up completely) without complex and error-prone synchronization code in FLTK.
The selection buffer is used for middle-mouse pastes and for drag-and-drop selections. The clipboard is used for traditional copy/cut/paste operations.

Backward compatibility only.
This calls Fl::paste(receiver, 0);
|
static |
Changes the current selection.
The block of text is copied to an internal buffer by FLTK (be careful if doing this in response to an FL_PASTE as this may be the same buffer returned by event_text()). The selection_owner() widget is set to the passed owner.
|
inlinestatic |
back-compatibility only: Gets the widget owning the current selection
|
static |
Back-compatibility only: The single-argument call can be used to move the selection to another widget or to set the owner to NULL, without changing the actual text of the selection.
FL_SELECTIONCLEAR is sent to the previous selection owner, if any.
Copying the buffer every time the selection is changed is obviously wasteful, especially for large selections. An interface will probably be added in a future version to allow the selection to be made by a callback function. The current interface will be emulated on top of this.
