Vec3 HoverRace::Display::SDL::SdlLabelView::Measure ( )

overridevirtual

Implements HoverRace::Display::View.

void HoverRace::Display::SDL::SdlLabelView::OnModelUpdate ( int  prop )

overridevirtual

Called by the view model to indicate that a property has changed.

The view can use this to decide if view-specific resources need to be reloaded.

Parameters

prop	The model-specific ID of the property that changed.

Reimplemented from HoverRace::Display::View.

void HoverRace::Display::SDL::SdlLabelView::PrepareRender ( )

overridevirtual

Implements HoverRace::Display::View.

void HoverRace::Display::SDL::SdlLabelView::Render ( )

overridevirtual

Implements HoverRace::Display::View.

void HoverRace::Display::SDL::SdlLabelView::UpdateBlank ( )

private

Update the state when the text is an empty string.

In this case, we measure the height of the string, and set the width to be 1 (to prevent accidental divisions by zero).
