Member Function Documentation

addWidget()

Widget & tt::ToolbarWidget::addWidget ( Alignment alignment, std::unique_ptr< Widget > childWidget )

overridevirtualnoexcept

Add a widget directly to this widget.

Thread safety: locks.

Reimplemented from tt::Widget.

draw()

void tt::ToolbarWidget::draw ( DrawContext const & drawContext, hires_utc_clock::time_point displayTimePoint )

overridevirtualnoexcept

Draw widget.

The overriding function should call the base class's draw(), the place where the call this function will determine the order of the vertices into each buffer. This is important when needing to do the painters algorithm for alpha-compositing. However the pipelines are always drawn in the same order.

Thread safety: locks, must be called from render-thread

Reimplemented from tt::Widget.

hitBoxTest()

HitBox tt::ToolbarWidget::hitBoxTest ( vec position ) const

overridevirtualnoexcept

Find the widget that is under the mouse cursor.

Thread safety: locks.

Reimplemented from tt::Widget.
