Struct gtk::Entry [−][src]
pub struct Entry(_);
Expand description
The 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.
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(). Since 2.16, GTK+ displays a warning
when Caps Lock or input methods might interfere with entering text in
a password entry. The warning can be turned off with the
property::Entry::caps-lock-warning property.
Since 2.16, GtkEntry 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, GtkEntry 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 a stock id, an
icon name or a pixbuf. To trigger an action when the user clicks an icon,
connect to the signal::Entry::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
⚠️ The following code is in plain ⚠️
entry[.read-only][.flat][.warning][.error]
├── image.left
├── image.right
├── undershoot.left
├── undershoot.right
├── [selection]
├── [progress[.pulse]]
╰── [window.popup]
GtkEntry 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 has a selection, it adds a subnode with the name selection.
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.
The CSS node for a context menu is added as a subnode below entry as well.
The undershoot nodes are used to draw the underflow indication when content is scrolled out of view. These nodes get the .left and .right style classes added depending on where the indication is drawn.
When touch is used and touch selection handles are shown, they are using CSS nodes with name cursor-handle. They get the .top or .bottom style class depending on where they are shown in relation to the selection. If there is just a single handle for the text cursor, it gets the style class .insertion-cursor.
