Class
GtkCellRendererCombo
Description [src]
class Gtk.CellRendererCombo : Gtk.CellRendererText
{
/* No available fields */
}GtkCellRendererCombo renders text in a cell like GtkCellRendererText from
which it is derived. But while GtkCellRendererText offers a simple entry to
edit the text, GtkCellRendererCombo offers a GtkComboBox
widget to edit the text. The values to display in the combo box are taken from
the tree model specified in the GtkCellRendererCombo:model property.
The combo cell renderer takes care of adding a text cell renderer to the combo
box and sets it to display the column specified by its
GtkCellRendererCombo:text-column property. Further properties of the combo box
can be set in a handler for the GtkCellRenderer::editing-started signal.
The GtkCellRendererCombo cell renderer was added in GTK+ 2.6.
Constructors
gtk_cell_renderer_combo_new
Creates a new GtkCellRendererCombo.
Adjust how text is drawn using object properties.
Object properties can be set globally (with g_object_set()).
Also, with GtkTreeViewColumn, you can bind a property to a value
in a GtkTreeModel. 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 GtkTreeView.

Instance methods
Methods inherited from GtkCellRendererText (1)
gtk_cell_renderer_text_set_fixed_height_from_font
Sets the height of a renderer to explicitly be determined by the “font” and
“y_pad” property set on it. Further changes in these properties do not
affect the height, so they must be accompanied by a subsequent call to this
function. Using this function is unflexible, and should really only be used
if calculating the size of a cell is too slow (ie, a massive number of cells
displayed). If number_of_rows is -1, then the fixed height is unset, and
the height is determined by the properties again.

Properties
Gtk.CellRendererCombo:has-entry
If TRUE, the cell renderer will include an entry and allow to enter
values other than the ones in the popup list.
since: 2.6
Gtk.CellRendererCombo:model
Holds a tree model containing the possible values for the combo box. Use the text_column property to specify the column holding the values.
since: 2.6
Gtk.CellRendererCombo:text-column
Specifies the model column which holds the possible values for the combo box.
since: 2.6
Properties inherited from GtkCellRendererText (48)
Gtk.CellRendererText:align-set
Gtk.CellRendererText:alignment
Specifies how to align the lines of text with respect to each other.
since: 2.10
Gtk.CellRendererText:attributes
Gtk.CellRendererText:background
Gtk.CellRendererText:background-gdk
Background color as a GdkColor.
deprecated: 3.4
Gtk.CellRendererText:background-rgba
Background color as a GdkRGBA.
since: 3.0
Gtk.CellRendererText:background-set
Gtk.CellRendererText:editable
Gtk.CellRendererText:editable-set
Gtk.CellRendererText: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_ELLIPSIZE_NONE turns off ellipsizing. See the wrap-width property
for another way of making the text fit into a given width.
since: 2.6

Gtk.CellRendererText:foreground-gdk
Foreground color as a GdkColor.
deprecated: 3.4
Gtk.CellRendererText:foreground-rgba
Foreground color as a GdkRGBA.
since: 3.0
Gtk.CellRendererText:foreground-set
Gtk.CellRendererText:language
Gtk.CellRendererText:language-set
Gtk.CellRendererText:markup
Gtk.CellRendererText: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.
since: 3.0
Gtk.CellRendererText:placeholder-text
The text that will be displayed in the GtkCellRenderer if
GtkCellRendererText:editable is TRUE and the cell is empty.

Gtk.CellRendererText:weight
Gtk.CellRendererText:weight-set
Gtk.CellRendererText:width-chars
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.
since: 2.6
Gtk.CellRendererText: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.
since: 2.8
Gtk.CellRendererText: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.
since: 2.8

Signals
Gtk.CellRendererCombo::changed
This signal is emitted each time after the user selected an item in
the combo box, either by using the mouse or the arrow keys. Contrary
to GtkComboBox, GtkCellRendererCombo::changed is not emitted for
changes made to a selected item in the entry. The argument new_iter
corresponds to the newly selected item in the combo box and it is relative
to the GtkTreeModel set via the model property on GtkCellRendererCombo.
since: 2.14
Signals inherited from GtkCellRendererText (1)
Signals inherited from GtkCellRenderer (2)
GtkCellRenderer::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.
since: 2.4
GtkCellRenderer::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 GtkEntryCompletion or setting
up additional columns in a GtkComboBox.
since: 2.6
Signals inherited from GObject (1)
GObject::notify
The notify signal is emitted on an object when one of its properties has its value set through g_object_set_property(), g_object_set(), et al.
