Struct gtk4::Entry

source ·
pub struct Entry { /* private fields */ }
Expand description

Entry is a single line text entry widget.

An example GtkEntry

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.

When using an entry for passwords and other sensitive information, it can be put into “password mode” using EntryExt::set_visibility(). In this mode, entered text is displayed using a “invisible” character. By default, GTK picks the best invisible character that is available in the current font, but it can be changed with EntryExt::set_invisible_char().

Entry has the ability to display progress or activity information behind the text. To make an entry display such information, use EntryExt::set_progress_fraction() or EntryExt::set_progress_pulse_step().

Additionally, Entry can show icons at either side of the entry. These icons can be activatable by clicking, can be set up as drag source and can have tooltips. To add an icon, use EntryExt::set_icon_from_gicon() or one of the various other functions that set an icon from an icon name or a paintable. To trigger an action when the user clicks an icon, connect to the icon-press signal. To allow DND operations from an icon, use EntryExt::set_icon_drag_source(). To set a tooltip on an icon, use EntryExt::set_icon_tooltip_text() or the corresponding function for markup.

Note that functionality or information that is only available by clicking on an icon in an entry may not be accessible at all to users which are not able to use a mouse or other pointing device. It is therefore recommended that any such functionality should also be available by other means, e.g. via the context menu of the entry.

§CSS nodes

entry[.flat][.warning][.error]
├── text[.readonly]
├── image.left
├── image.right
╰── [progress[.pulse]]

Entry has a main node with the name entry. Depending on the properties of the entry, the style classes .read-only and .flat may appear. The style classes .warning and .error may also be used with entries.

When the entry shows icons, it adds subnodes with the name image and the style class .left or .right, depending on where the icon appears.

When the entry shows progress, it adds a subnode with the name progress. The node has the style class .pulse when the shown progress is pulsing.

For all the subnodes added to the text node in various situations, see Text.

§GtkEntry as GtkBuildable

The Entry implementation of the Buildable interface supports a custom <attributes> element, which supports any number of <attribute> elements. The <attribute> element has attributes named “name“, “value“, “start“ and “end“ and allows you to specify PangoAttribute values for this label.

An example of a UI definition fragment specifying Pango attributes:

<object class="GtkEntry">
  <attributes>
    <attribute name="weight" value="PANGO_WEIGHT_BOLD"/>
    <attribute name="background" value="red" start="5" end="10"/>
  </attributes>
</object>

The start and end attributes specify the range of characters to which the Pango attribute applies. If start and end are not specified, the attribute is applied to the whole text. Note that specifying ranges does not make much sense with translatable attributes. Use markup embedded in the translatable content instead.

§Accessibility

Entry uses the AccessibleRole::TextBox role.

§Properties

§activates-default

Whether to activate the default widget when Enter is pressed.

Readable | Writeable

§attributes

A list of Pango attributes to apply to the text of the entry.

This is mainly useful to change the size or weight of the text.

The PangoAttribute’s @start_index and @end_index must refer to the EntryBuffer text, i.e. without the preedit string.

§Signals

§activate

Emitted when the entry is activated.

The keybindings for this signal are all forms of the Enter key.

Action

§icon-press

Emitted when an activatable icon is clicked.

§icon-release

Emitted on the button release from a mouse click over an activatable icon.

Widget

§destroy

Signals that all holders of a reference to the widget should release the reference that they hold.

May result in finalization of the widget if all references are released.

This signal is not suitable for saving widget state.

§direction-changed

Emitted when the text direction of a widget changes.

§hide

Emitted when @widget is hidden.

§keynav-failed

Emitted if keyboard navigation fails.

See WidgetExt::keynav_failed() for details.

§map

Emitted when @widget is going to be mapped.

A widget is mapped when the widget is visible (which is controlled with visible) and all its parents up to the toplevel widget are also visible.

The ::map signal can be used to determine whether a widget will be drawn, for instance it can resume an animation that was stopped during the emission of unmap.

§mnemonic-activate

Emitted when a widget is activated via a mnemonic.

The default handler for this signal activates @widget if @group_cycling is false, or just makes @widget grab focus if @group_cycling is true.

§move-focus

Emitted when the focus is moved.

The ::move-focus signal is a keybinding signal.

The default bindings for this signal are Tab to move forward, and Shift+Tab to move backward.

Action

§query-tooltip

Emitted when the widget’s tooltip is about to be shown.

This happens when the has-tooltip property is true and the hover timeout has expired with the cursor hovering “above” @widget; or emitted when @widget got focus in keyboard mode.

Using the given coordinates, the signal handler should determine whether a tooltip should be shown for @widget. If this is the case true should be returned, false otherwise. Note that if @keyboard_mode is true, the values of @x and @y are undefined and should not be used.

The signal handler is free to manipulate @tooltip with the therefore destined function calls.

§realize

Emitted when @widget is associated with a gdk::Surface.

This means that WidgetExt::realize() has been called or the widget has been mapped (that is, it is going to be drawn).

§show

Emitted when @widget is shown.

§state-flags-changed

Emitted when the widget state changes.

See WidgetExt::state_flags().

§unmap

Emitted when @widget is going to be unmapped.

A widget is unmapped when either it or any of its parents up to the toplevel widget have been set as hidden.

As ::unmap indicates that a widget will not be shown any longer, it can be used to, for example, stop an animation on the widget.

§unrealize

Emitted when the gdk::Surface associated with @widget is destroyed.

This means that WidgetExt::unrealize() has been called or the widget has been unmapped (that is, it is going to be hidden).

CellEditable

§editing-done

This signal is a sign for the cell renderer to update its value from the @cell_editable.

Implementations of CellEditable are responsible for emitting this signal when they are done editing, e.g. Entry emits this signal when the user presses Enter. Typical things to do in a handler for ::editing-done are to capture the edited value, disconnect the @cell_editable from signals on the CellRenderer, etc.

gtk_cell_editable_editing_done() is a convenience method for emitting GtkCellEditable::editing-done.

§remove-widget

This signal is meant to indicate that the cell is finished editing, and the @cell_editable widget is being removed and may subsequently be destroyed.

Implementations of CellEditable are responsible for emitting this signal when they are done editing. It must be emitted after the GtkCellEditable::editing-done signal, to give the cell renderer a chance to update the cell’s value before the widget is removed.

gtk_cell_editable_remove_widget() is a convenience method for emitting GtkCellEditable::remove-widget.

Editable

§changed

Emitted at the end of a single user-visible operation on the contents.

E.g., a paste operation that replaces the contents of the selection will cause only one signal emission (even though it is implemented by first deleting the selection, then inserting the new content, and may cause multiple ::notify::text signals to be emitted).

§delete-text

Emitted when text is deleted from the widget by the user.

The default handler for this signal will normally be responsible for deleting the text, so by connecting to this signal and then stopping the signal with g_signal_stop_emission(), it is possible to modify the range of deleted text, or prevent it from being deleted entirely.

The @start_pos and @end_pos parameters are interpreted as for EditableExt::delete_text().

§insert-text

Emitted when text is inserted into the widget by the user.

The default handler for this signal will normally be responsible for inserting the text, so by connecting to this signal and then stopping the signal with g_signal_stop_emission(), it is possible to modify the inserted text, or prevent it from being inserted entirely.
