Struct gtk4::PasswordEntry

pub struct PasswordEntry { /* private fields */ }

PasswordEntry is an entry that has been tailored for entering secrets.

It does not show its contents in clear text, does not allow to copy it to the clipboard, and it shows a warning when Caps Lock is engaged. If the underlying platform allows it, PasswordEntry will also place the text in a non-pageable memory area, to avoid it being written out to disk by the operating system.

Optionally, it can offer a way to reveal the contents in clear text.

PasswordEntry provides only minimal API and should be used with the Editable API.

CSS Nodes

entry.password
╰── text

PasswordEntry has a single CSS node with name entry that carries a .passwordstyle class. The text Css node below it has a child with name image and style class .caps-lock-indicator for the Caps Lock icon, and possibly other children.

Accessibility

PasswordEntry uses the AccessibleRole::TextBox role.

Signals

activate

Emitted when the entry is activated.

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

Action

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).

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.
