CellRenderer size

[Roger Ferrer Ibáñez <rofi ya com>]

Hi,

I'm writing a CellRenderer and it is unclear to me how the CellRenderer
tells the related TreeView the size it will require when drawing.

I've seen that there is CellRenderer::set_fixed_size but I don't know if
this is the proper way to achieve this.

Thank you,
