integer between 0 and allocation.get_width()

virtual Gdk::RGBA& CairoSlider::get_inactive_color

)

[protected, virtual]

Get the inactive color of the slider.

Returns:

virtual bool CairoSlider::on_draw

(

const Cairo::RefPtr< Cairo::Context > &

cr

)

[protected, pure virtual]

Override to draw the widget.

on_draw() is always called when the widget needs to be redrawn, therefore all drawing logic should happen here, possibly in a optimized way.

Returns:

true if everything is handeled, false to let other callbacks be called
