Member Function Documentation

draw()

void tt::WindowTrafficLightsWidget::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.

handleMouseEvent()

void tt::WindowTrafficLightsWidget::handleMouseEvent ( MouseEvent const & event )

overridevirtualnoexcept

Handle mouse event. Called by the operating system to show the position and button state of the mouse. This is called very often so it must be made efficient. This function is also used to determine the mouse cursor.

Thread safety: locks

Reimplemented from tt::Widget.

hitBoxTest()

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

overridevirtualnoexcept

Find the widget that is under the mouse cursor.

Thread safety: locks.

Reimplemented from tt::Widget.

layout()

void tt::WindowTrafficLightsWidget::layout ( hires_utc_clock::time_point displayTimePoint )

overridevirtualnoexcept

Layout the widget.

super::layout() should be called at start of the overriden function.

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

Reimplemented from tt::Widget.
