Struct gtk4::CellRendererText [−][src]
pub struct CellRendererText(_);
Expand description
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.

, CellRendererExtManual
Implementations
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
.
Returns
the new cell renderer
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.

Tries to cast to an object of type T
. This handles upcasting, downcasting
and casting between interface and interface implementors. All checks are performed at
runtime, while downcast

will do many checks at compile-time already. Read more
