Struct gtk4::CellRendererText
source · #[repr(transparent)]pub struct CellRendererText { /* private fields */ }
Expand description
List views use widgets to display their contents.
You should use Inscription
or Label
instead
Renders text in a cell
A CellRendererText
renders a given text in its cell, using the font, color and
style information provided by its properties. The text will be ellipsized if it is
too long and the GtkCellRendererText:ellipsize
property allows it.
If the GtkCellRenderer:mode
is CellRendererMode::Editable
,
the CellRendererText
allows to edit its text using an entry.
Properties
align-set
Readable | Writeable
alignment
Specifies how to align the lines of text with respect to each other.
Note that this property describes how to align the lines of text in
case there are several of them. The “xalign” property of CellRenderer
,
on the other hand, sets the horizontal alignment of the whole text.

ellipsize
Specifies the preferred place to ellipsize the string, if the cell renderer
does not have enough room to display the entire string. Setting it to
pango::EllipsizeMode::None
turns off ellipsizing. See the wrap-width property
for another way of making the text fit into a given width.

Writeable
max-width-chars
The desired maximum width of the cell, in characters. If this property is set to -1, the width will be calculated automatically.
For cell renderers that ellipsize or wrap text; this property
controls the maximum reported width of the cell. The
cell should not receive any greater allocation unless it is
set to expand in its CellLayout
and all of the cell’s siblings
have received their natural width.
Readable | Writeable
placeholder-text
The text that will be displayed in the CellRenderer
if
GtkCellRendererText:editable
is true
and the cell is empty.

The desired width of the cell, in characters. If this property is set to -1, the width will be calculated automatically, otherwise the cell will request either 3 characters or the property value, whichever is greater.
Readable | Writeable
wrap-mode
Specifies how to break the string into multiple lines, if the cell renderer does not have enough room to display the entire string. This property has no effect unless the wrap-width property is set.
Readable | Writeable
wrap-width
Specifies the minimum width at which the text is wrapped. The wrap-mode property can be used to influence at what character positions the line breaks can be placed. Setting wrap-width to -1 turns wrapping off.

Signals
edited
This signal is emitted after @renderer has been edited.
It is the responsibility of the application to update the model and store @new_text at the position indicated by @path.
CellRenderer
editing-canceled
This signal gets emitted when the user cancels the process of editing a cell. For example, an editable cell renderer could be written to cancel editing when the user presses Escape.
See also: gtk_cell_renderer_stop_editing().
editing-started
This signal gets emitted when a cell starts to be edited.
The intended use of this signal is to do special setup
on @editable, e.g. adding a EntryCompletion
or setting
up additional columns in a ComboBox
.
See gtk_cell_editable_start_editing() for information on the lifecycle of the @editable and a way to do setup that doesn’t depend on the @renderer.
Note that GTK doesn’t guarantee that cell renderers will continue to use the same kind of widget for editing in future releases, therefore you should check the type of @editable before doing any specific setup, as in the following example:
⚠️ The following code is in C ⚠️
static void
text_editing_started (GtkCellRenderer *cell,
GtkCellEditable *editable,
const char *path,
gpointer data)
{
if (GTK_IS_ENTRY (editable))
{
GtkEntry *entry = GTK_ENTRY (editable);
// ... create a GtkEntryCompletion
gtk_entry_set_completion (entry, completion);
}
}

Implementations§
source§impl CellRendererText
impl CellRendererText
pub const NONE: Option<&'static CellRendererText> = None
sourcepub fn new() -> CellRendererText
pub fn new() -> CellRendererText
Creates a new CellRendererText
. Adjust how text is drawn using
object properties. Object properties can be
set globally (with g_object_set()). Also, with TreeViewColumn
,
you can bind a property to a value in a TreeModel
. For example,
you can bind the “text” property on the cell renderer to a string
value in the model, thus rendering a different string in each row
of the TreeView
.
Deprecated since 4.10
Returns
the new cell renderer
sourcepub fn builder() -> CellRendererTextBuilder
pub fn builder() -> CellRendererTextBuilder
Creates a new builder-pattern struct instance to construct CellRendererText
objects.
This method returns an instance of CellRendererTextBuilder
which can be used to create CellRendererText
objects.
