List of all members.

## Detailed Description

Base class for text-editing widgets.

The Gtk::Editable class is a base class for widgets for editing text, such as Gtk::Entry. It cannot be instantiated by itself. The editable class contains functions for generically manipulating an editable widget, a large number of action signals used for key bindings, and several signals that an application can connect to to modify the behavior of a widget.

## Member Function Documentation

static void Gtk::Editable::add_interface | ( | GType | gtype_implementer | ) | `[static]`

void Gtk::Editable::copy_clipboard | ( |  | ) |

Copies the contents of the currently selected content in the editable and puts it on the clipboard.

void Gtk::Editable::cut_clipboard | ( |  | ) |

Removes the contents of the currently selected content in the editable and puts it on the clipboard.

void Gtk::Editable::delete_selection | ( |  | ) |

Deletes the currently selected text of the editable.

This call will not do anything if there is no selected text.

void Gtk::Editable::delete_text | ( | int | start_pos,
|  | int | end_pos |
| ) |  |  |

Deletes the content of the editable between start_pos and end_pos.

Note that positions are specified in characters, not bytes.

Parameters:

  | start_pos | Start position.
  | end_pos | End position.

virtual void Gtk::Editable::delete_text_vfunc | ( | int | start_pos,
|  | int | end_pos |
| ) |  |  | `[protected, virtual]`

Glib::ustring Gtk::Editable::get_chars | ( | int | start_pos,
|  | int | end_pos |
| ) |  |  | const

Retreives the content of the editable between start and end.

Note that positions are specified in characters, not bytes.

Parameters:

  | start | Start of text.
  | end | End of text.

Returns:
  A pointer to the contents of the widget as a string. This string is allocated by the Gtk::Editable implementation and should be freed by the caller.

virtual Glib::ustring Gtk::Editable::get_chars_vfunc | ( | int | start_pos,
|  | int | end_pos |
| ) |  |  | const`[protected, virtual]`

bool Gtk::Editable::get_editable | ( |  | ) | const

Retrieves whether editable is editable.

See set_editable().

Returns:
  `true` if editable is editable.

int Gtk::Editable::get_position | ( |  | ) | const

Retrieves the current position of the cursor relative to the start of the content of the editable.

Note that this position is in characters, not in bytes.

Returns:
  The cursor position.

virtual int Gtk::Editable::get_position_vfunc | ( |  | ) | const`[protected, virtual]`

bool Gtk::Editable::get_selection_bounds | ( | int & | start_pos,
|  | int & | end_pos |
| ) |  |  | const

Retrieves the selection bound of the editable.

start_pos will be filled with the start of the selection and end_pos with end. If no text was selected both will be identical and `false` will be returned. Note that positions are specified in characters, not bytes.

Parameters:

  | start_pos | Beginning of selection.
  | end_pos | End of selection.

Returns:
  `true` if an area is selected, `false` otherwise.

void Gtk::Editable::select_region | ( | int | start_pos,
|  | int | end_pos |
| ) |  |  |

Selects the text between start and end.

Both start and end are relative to the start of the content. Note that positions are specified in characters, not bytes.

Parameters:

Parameters:

  | position | The position of the cursor. The cursor is displayed before the character with the given (base 0) index in the editable. The value must be less than or equal to the number of characters in the editable. A value of -1 indicates that the position should be set after the last character of the editable. Note that this position is in characters, not in bytes.
