They display, and allow editing of, the values of their _property_renderable() properties. In most cases, Gtl::TreeView::append_column() will automatically choose the appropriate renderer for the mode column's data type, so you will rarely need to worry about these classes.

Returns the property that this CellRenderer renders. For instance, property_text for CellRendererText, and property_active for CellRendererToggle Needs to be overridden in derived classes. Reimplemented in Gtk::CellRendererCombo, Gtk::CellRendererPixbuf, Gtk::CellRendererProgress, Gtk::CellRendererText, and Gtk::CellRendererToggle. |
|
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.

|
Causes the cell renderer to emit the "editing-canceled" signal. This function is for use only by implementations of cell renderers that need to notify the client program that an editing process was canceled and the changes were not committed. Since: 2.4 |

Fills in width and height with the appropriate size of cell .
|
|
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 render(). Fills in the x and y offsets of the cell relative to this location. Please note that the values set in width and height , as well as those in x_offset and y_offset are inclusive of the xpad and ypad properties.

Override this in derived CellRenderers. 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 render(). If cell_area is not 0, fills in the x and y offsets (if set) of the cell relative to this location. Please note that the values set in width and height, as well as those in x_offset and y_offset are inclusive of the xpad and ypad properties.

Invokes the virtual render function of the Gtk::CellRenderer. The three passed-in rectangles are areas of window . 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 . expose_area is a clip rectangle.

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