List views use widgets for displaying their contents

An object for rendering a single cell

The GtkCellRenderer is a base class of a set of objects used for rendering a cell to a cairo_t. These objects are used primarily by the GtkTreeView widget, though they aren’t tied to them in any specific way. It is worth noting that GtkCellRenderer is not a GtkWidget and cannot be treated as such.

The primary use of a GtkCellRenderer is for drawing a certain graphical elements on a cairo_t. Typically, one cell renderer is used to draw many cells on the screen. To this extent, it isn’t expected that a CellRenderer keep any permanent state around. Instead, any state is set just prior to use using GObjects property system. Then, the cell is measured using gtk_cell_renderer_get_preferred_size(). Finally, the cell is rendered in the correct location using gtk_cell_renderer_snapshot().

There are a number of rules that must be followed when writing a new GtkCellRenderer. First and foremost, it’s important that a certain set of properties will always yield a cell renderer of the same size, barring a style change. The GtkCellRenderer also has a number of generic properties that are expected to be honored by all children.

Beyond merely rendering a cell, cell renderers can optionally provide active user interface elements. A cell renderer can be “activatable” like GtkCellRendererToggle, which toggles when it gets activated by a mouse click, or it can be “editable” like GtkCellRendererText, which allows the user to edit the text using a widget implementing the GtkCellEditable interface, e.g. GtkEntry. To make a cell renderer activatable or editable, you have to implement the GtkCellRendererClass.activate or GtkCellRendererClass.start_editing virtual functions, respectively.

Many properties of GtkCellRenderer and its subclasses have a corresponding “set” property, e.g. “cell-background-set” corresponds to “cell-background”. These “set” properties reflect whether a property has been set or not. You should not set them independently.

Constructor Details

CellRenderer

public CellRenderer(MemorySegment address)

Deprecated.

Create a CellRenderer proxy instance for the provided memory address.

Parameters:

address - the memory address of the native object

CellRenderer

public CellRenderer()

Deprecated.

Creates a new CellRenderer.

Method Details

getType

public static @Nullable Type getType()

Deprecated.

Get the GType of the CellRenderer class

Returns:

the GType

getMemoryLayout

public static MemoryLayout getMemoryLayout()

Deprecated.

The memory layout of the native struct.

Returns:

the memory layout

asParent

protected CellRenderer asParent()

Deprecated.

Returns this instance as if it were its parent type. This is mostly synonymous to the Java super keyword, but will set the native typeclass function pointers to the parent type. When overriding a native virtual method in Java, "chaining up" with super.methodName() doesn't work, because it invokes the overridden function pointer again. To chain up, call asParent().methodName(). This will call the native function pointer of this virtual method in the typeclass of the parent type.

Overrides:

asParent in class InitiallyUnowned

Parameters:

snapshot - a GtkSnapshot to draw to

widget - the widget owning window

backgroundArea - entire cell area (including tree expanders and maybe padding on the sides)

cellArea - area normally rendered by a cell renderer

flags - flags that affect rendering

stopEditing

@Deprecated
public void stopEditing(boolean canceled)

Deprecated.

Informs the cell renderer that the editing is stopped. If canceled is true, the cell renderer will emit the GtkCellRenderer::editing-canceled signal.

This function should be called by cell renderer implementations in response to the GtkCellEditable::editing-done signal of GtkCellEditable.

Parameters:

canceled - true if the editing has been canceled

editingCanceled

protected void editingCanceled()

Deprecated.

Signal gets emitted when the user cancels the process of editing a cell.

editingStarted

protected void editingStarted(CellEditable editable,
 String path)

Deprecated.

Signal gets emitted when a cell starts to be edited.

onEditingCanceled

public SignalConnection<CellRenderer.EditingCanceledCallback> onEditingCanceled(CellRenderer.EditingCanceledCallback handler)

Deprecated.

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().

Parameters:

handler - the signal handler

Returns:

a signal handler ID to keep track of the signal connection

See Also:

• CellRenderer.EditingCanceledCallback.run()

emitEditingCanceled

public void emitEditingCanceled()

Deprecated.

Emits the "editing-canceled" signal. See onEditingCanceled(org.gnome.gtk.CellRenderer.EditingCanceledCallback).

onEditingStarted

public SignalConnection<CellRenderer.EditingStartedCallback> onEditingStarted(CellRenderer.EditingStartedCallback handler)

Deprecated.

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.

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:

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);
     }
 }
 

Parameters:

handler - the signal handler

Returns:

a signal handler ID to keep track of the signal connection

See Also:

• CellRenderer.EditingStartedCallback.run(org.gnome.gtk.CellEditable, java.lang.String)

emitEditingStarted

public void emitEditingStarted(@Nullable CellEditable editable,
 String path)

Deprecated.

Emits the "editing-started" signal. See onEditingStarted(org.gnome.gtk.CellRenderer.EditingStartedCallback).
