Expand description

Trait containing all CellRenderer methods.

Implementors

CellRendererPixbuf, CellRendererProgress, CellRendererSpinner, CellRendererText, CellRendererToggle, CellRenderer

Required Methods§

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

Deprecated since 4.10
event

a gdk::Event

widget

widget that received the event

path

widget-dependent string representation of the event location; e.g. for TreeView, a string representation of TreePath

background_area

background area as passed to gtk_cell_renderer_render()

cell_area

cell area as passed to gtk_cell_renderer_render()

flags

render flags

Returns

true if the event was consumed/handled
