List of all members.

## Detailed Description

A single line text entry field.

The Gtk::Entry widget is a single line text entry widget. A fairly large set of key bindings are supported by default. If the entered text is longer than the allocation of the widget, the widget will scroll so that the cursor position is visible.

Gets the value set by set_has_frame().

Returns:
  Whether the entry has a beveled frame.

Border Gtk::Entry::get_inner_border | ( |  | ) | const

This function returns the entry's Gtk::Entry:inner-border property.

See set_inner_border() for more information.

Glib::RefPtr<const Pango::Layout> Gtk::Entry::get_layout | ( |  | ) | const

Gets the Pango::Layout used to display the entry.

The layout is useful to e.g. convert text positions to pixel positions, in combination with get_layout_offsets(). The returned layout is owned by the entry and must not be modified or freed by the caller.

Keep in mind that the layout text may contain a preedit string, so layout_index_to_text_index() and text_index_to_layout_index() are needed to convert byte indices in the layout to byte indices in the entry contents.

Returns:
  The Pango::Layout for this entry.

Glib::RefPtr<Pango::Layout> Gtk::Entry::get_layout | ( |  | ) |

Gets the Pango::Layout used to display the entry.

The layout is useful to e.g. convert text positions to pixel positions, in combination with get_layout_offsets(). The returned layout is owned by the entry and must not be modified or freed by the caller.

Keep in mind that the layout text may contain a preedit string, so layout_index_to_text_index() and text_index_to_layout_index() are needed to convert byte indices in the layout to byte indices in the entry contents.

Returns:
  The Pango::Layout for this entry.

void Gtk::Entry::get_layout_offsets | ( | int & | x,
|  | int & | y |
| ) |  |  |

Obtains the position of the Pango::Layout used to render text in the entry, in widget coordinates.

Useful if you want to line up the text in an entry with some other text, e.g. when using the entry to implement editable cells in a sheet widget.

Also useful to convert mouse events into coordinates inside the Pango::Layout, e.g. to take some action if some part of the entry text is clicked.

Note that as the user scrolls around in the entry the offsets will change; you'll need to connect to the "notify::scroll-offset" signal to track this. Remember when using the Pango::Layout functions you need to convert to and from pixels using PANGO_PIXELS() or Pango::SCALE.

Keep in mind that the layout text may contain a preedit string, so layout_index_to_text_index() and text_index_to_layout_index() are needed to convert byte indices in the layout to byte indices in the entry contents.

Parameters:

  | x | Location to store X offset of layout, or `0`.
  | y | Location to store Y offset of layout, or `0`.

int Gtk::Entry::get_max_length | ( |  | ) | const

Retrieves the maximum allowed length of the text in entry .

Returns:
  A PropertyProxy that allows you to get or set the property of the value, or receive notification when the value of the property changes.

void Gtk::Entry::set_activates_default | ( | bool | setting = `true` | ) |

If setting is `true`, pressing Enter in the entry will activate the default widget for the window containing the entry.

This usually means that the dialog box containing the entry will be closed, since the default widget is usually one of the dialog buttons.

(For experts: if setting is `true`, the entry calls Gtk::Window::activate_default() on the window containing the entry, in the default handler for the Gtk::Widget::activate signal.)

Parameters:

  | setting | `true` to activate window's default widget on Enter keypress.

void Gtk::Entry::set_alignment | ( | AlignmentEnum | xalign | ) |

Sets the alignment for the contents of the entry.

This controls the horizontal positioning of the contents when the displayed text is shorter than the width of the entry.

Since gtkmm 2.4:

Parameters:

  | xalign | The horizontal alignment, from 0 (left) to 1 (right). Reversed for RTL layouts.

void Gtk::Entry::set_alignment | ( | float | xalign | ) |

Sets the alignment for the contents of the entry.

This controls the horizontal positioning of the contents when the displayed text is shorter than the width of the entry.

Since gtkmm 2.4:

Parameters:

  | xalign | The horizontal alignment, from 0 (left) to 1 (right). Reversed for RTL layouts.

void Gtk::Entry::set_completion | ( | const Glib::RefPtr<EntryCompletion>& | completion | ) |

Sets completion to be the auxiliary completion object to use with entry .

All further configuration of the completion mechanism is done on completion using the Gtk::EntryCompletion API. Completion is disabled if completion is set to `0`.

Since gtkmm 2.4:

Parameters:

  | completion | The Gtk::EntryCompletion or `0`.

void Gtk::Entry::set_cursor_hadjustment | ( | Adjustment& | adjustment | ) |

Hooks up an adjustment to the cursor position in an entry, so that when the cursor is moved, the adjustment is scrolled to show that position.

See Gtk::ScrolledWindow::get_hadjustment() for a typical way of obtaining the adjustment.

The adjustment has to be in pixel units and in the same coordinate system as the entry.

Since gtkmm 2.12:

Parameters:

  | adjustment | An adjustment which should be adjusted when the cursor is moved, or `0`.

void Gtk::Entry::set_has_frame | ( | bool | setting = `true` | ) |

Sets whether the entry has a beveled frame around it.

Parameters:

  | setting | New value.

void Gtk::Entry::set_inner_border | ( | const Border& | border | ) |

Sets entry's inner-border property to border, or clears it if `0` is passed.

The inner-border is the area around the entry's text, but inside its frame.

If set, this property overrides the inner-border style property. Overriding the style-provided border is useful when you want to do in-place editing of some text in a canvas or list widget, where pixel-exact positioning of the entry is important.

Since gtkmm 2.10:

Parameters:

  | border | A Gtk::Border, or `0`.

void Gtk::Entry::set_invisible_char | ( | gunichar | ch | ) |

Sets the character to use in place of the actual text when set_visibility() has been called to set text visibility to `false`.

i.e. this is the character used in "password mode" to show the user how many characters have been typed. The default invisible char is an asterisk ('*'). If you set the invisible char to 0, then the user will get no feedback at all; there will be no text on the screen as they type.

Parameters:

  | ch | A Unicode character.

void Gtk::Entry::set_max_length | ( | int | max | ) |

Sets the maximum allowed length of the contents of the widget.

If the current contents are longer than the given length, then they will be truncated to fit.

Parameters:

  | max | The maximum length of the entry, or 0 for no maximum. (other than the maximum length of entries.) The value passed in will be clamped to the range 0-65536.

void Gtk::Entry::set_text | ( | const Glib::ustring & | text | ) |

Sets the text in the widget to the given value, replacing the current contents.

Parameters:

  | text | The new text.

void Gtk::Entry::set_visibility | ( | bool | visible = `true` | ) |

Sets whether the contents of the entry are visible or not.

When visibility is set to `false`, characters are displayed as the invisible char, and will also appear that way when the text in the entry widget is copied elsewhere.

The default invisible char is the asterisk '*', but it can be changed with set_invisible_char().

Parameters:

  | visible | `true` if the contents of the entry are displayed as plaintext.

void Gtk::Entry::set_width_chars | ( | int | n_chars | ) |

Changes the size request of the entry to be about the right size for n_chars characters.

Note that it changes the size request, the size can still be affected by how you pack the widget into containers. If n_chars is -1, the size reverts to the default entry size.

Parameters:

  | n_chars | Width in chars.

Parameters:

  | text_index | Byte index into the entry contents.

Returns:
  Byte index into the entry layout text.
