Class
GtkText
Description [src]
final class Gtk.Text : Gtk.Widget {
/* No available fields */
}
The GtkText
widget is a single-line text entry widget.
GtkText
is the common implementation of single-line text editing
that is shared between GtkEntry
, GtkPasswordEntry
, GtkSpinButton
and other widgets. In all of these, GtkText
is used as the delegate
for the GtkEditable
implementation.
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 gtk_text_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
gtk_text_set_invisible_char()
.
If you are looking to add icons or progress display in an entry, look
at GtkEntry
. There other alternatives for more specialized use cases,
such as GtkSearchEntry
.
If you need multi-line editable text, look at GtkTextView
.
CSS nodes
text[.read-only]
├── placeholder
├── undershoot.left
├── undershoot.right
├── [selection]
├── [block-cursor]
╰── [window.popup]
GtkText
has a main node with the name text. Depending on the properties
of the widget, the .read-only style class may appear.
When the entry has a selection, it adds a subnode with the name selection.
When the entry is in overwrite mode, it adds a subnode with the name block-cursor that determines how the block cursor is drawn.
The CSS node for a context menu is added as a subnode below text 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.
Accessibility
GtkText
uses the GTK_ACCESSIBLE_ROLE_NONE
role, which causes it to be
skipped for accessibility. This is because GtkText
is expected to be used
as a delegate for a GtkEditable
implementation that will be represented
to accessibility.
