CellRendererImpl

Creates a new instance of CellRenderer for the provided CPointer.

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

Emits the "editing-canceled" signal. See onEditingCanceled.

Emits the "editing-started" signal. See onEditingStarted.

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

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

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

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

Checks whether the cell renderer can do something when activated.

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.

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.

Sets the renderer’s alignment within its available space.

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

Sets the renderer’s padding.

Invokes the virtual render function of the GtkCellRenderer. The three passed-in rectangles are areas in @cr. Most renderers will draw within

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

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