CellRendererPixbuf

A gtk.CellRendererPixbuf can be used to render an image in a cell. It allows to render either a given gdk.Pixbuf (set via the pixbuf property) or a named icon (set via the icon-name property).

To support the tree view, gtk.CellRendererPixbuf also supports rendering two alternative pixbufs, when the is-expander property is TRUE. If the is-expanded property is TRUE and the pixbuf-expander-open property is set to a pixbuf, it renders that pixbuf, if the is-expanded property is FALSE and the pixbuf-expander-closed property is set to a pixbuf, it renders that one.

Constructors

this
this(GtkCellRendererPixbuf* gtkCellRendererPixbuf, bool ownedRef)

Sets our main struct and passes it to the parent class.

this
this()

Creates a new gtk.CellRendererPixbuf Adjust rendering parameters using object properties. Object properties can be set globally (with g_object_set()). Also, with gtk.TreeViewColumn, you can bind a property to a value in a gtk.TreeModel For example, you can bind the “pixbuf” property on the cell renderer to a pixbuf value in the model, thus rendering a different image in each row of the gtk.TreeView

activate
bool activate(Event event, Widget widget, string path, GdkRectangle* backgroundArea, GdkRectangle* cellArea, GtkCellRendererState flags)

Passes an activate event to the cell renderer for possible processing. Some cell renderers may use events; for example, gtk.CellRendererToggle toggles when it gets a mouse click.

getAlignedArea
void getAlignedArea(Widget widget, GtkCellRendererState flags, GdkRectangle* cellArea, GdkRectangle alignedArea)

Gets the aligned area used by cell inside cell_area. Used for finding the appropriate edit and focus rectangle.

getAlignment
void getAlignment(float xalign, float yalign)

Fills in xalign and yalign with the appropriate values of cell.

getFixedSize
void getFixedSize(int width, int height)

Fills in width and height with the appropriate size of cell.

getPadding
void getPadding(int xpad, int ypad)

Fills in xpad and ypad with the appropriate values of cell.

getPreferredHeight
void getPreferredHeight(Widget widget, int minimumSize, int naturalSize)

Retreives a renderer’s natural size when rendered to widget.

getPreferredHeightForWidth
void getPreferredHeightForWidth(Widget widget, int width, int minimumHeight, int naturalHeight)

Retreives a cell renderers’s minimum and natural height if it were rendered to widget with the specified width.

getPreferredSize
void getPreferredSize(Widget widget, Requisition minimumSize, Requisition naturalSize)

Retrieves the minimum and natural size of a cell taking into account the widget’s preference for height-for-width management.

getPreferredWidth
void getPreferredWidth(Widget widget, int minimumSize, int naturalSize)

Retreives a renderer’s natural size when rendered to widget.

getPreferredWidthForHeight
void getPreferredWidthForHeight(Widget widget, int height, int minimumWidth, int naturalWidth)

Retreives a cell renderers’s minimum and natural width if it were rendered to widget with the specified height.

getRequestMode
GtkSizeRequestMode getRequestMode()

Gets whether the cell renderer prefers a height-for-width layout or a width-for-height layout.

getSensitive
bool getSensitive()

Returns the cell renderer’s sensitivity.

getSize
void getSize(Widget widget, GdkRectangle* cellArea, int xOffset, int yOffset, int width, int height)

Obtains the width and height needed to render the cell. Used by view widgets to determine the appropriate size for the cell_area passed to CellRenderer.render. If cell_area is not NULL, fills in the x and y offsets (if set) of the cell relative to this location.

getState
GtkStateFlags getState(Widget widget, GtkCellRendererState cellState)

Translates the cell renderer state to GtkStateFlags, based on the cell renderer and widget sensitivity, and the given GtkCellRendererState

getVisible
bool getVisible()

Returns the cell renderer’s visibility.

isActivatable
bool isActivatable()

Checks whether the cell renderer can do something when activated.

render
void render(Context cr, Widget widget, GdkRectangle* backgroundArea, GdkRectangle* cellArea, GtkCellRendererState flags)

Invokes the virtual render function of the gtk.CellRenderer The three passed-in rectangles are areas in cr. Most renderers will draw within cell_area; the xalign, yalign, xpad, and ypad fields of the gtk.CellRenderer should be honored with respect to cell_area. background_area includes the blank space around the cell, and also the area containing the tree expander; so the background_area rectangles for all cells tile to cover the entire window.

setAlignment
void setAlignment(float xalign, float yalign)

Sets the renderer’s alignment within its available space.

setFixedSize
void setFixedSize(int width, int height)

Sets the renderer size to be explicit, independent of the properties set.

setPadding
void setPadding(int xpad, int ypad)

Sets the renderer’s padding.

setSensitive
void setSensitive(bool sensitive)

Sets the cell renderer’s sensitivity.

setVisible
void setVisible(bool visible)

Sets the cell renderer’s visibility.

startEditing
CellEditableIF startEditing(Event event, Widget widget, string path, GdkRectangle* backgroundArea, GdkRectangle* cellArea, GtkCellRendererState flags)

Starts editing the contents of this cell, through a new GtkCellEditable widget created by the gtk.CellRendererClass.start_editing virtual function.

stopEditing
void stopEditing(bool canceled)

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

addOnEditingCanceled
gulong addOnEditingCanceled(void delegate(CellRenderer) dlg, ConnectFlags connectFlags)

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.

addOnEditingStarted
gulong addOnEditingStarted(void delegate(CellEditableIF, string, CellRenderer) dlg, ConnectFlags connectFlags)

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 gtk.EntryCompletion or setting up additional columns in a gtk.ComboBox
