draw_impl()

bool TeXView::TeXArea::draw_impl

(

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

cr

)

The actual painting, shared between the two toolkits.

gtkmm-3 reaches it through the on_draw vfunc, GTK4 through the callback registered with set_draw_func().

layout_latex()

void TeXView::TeXArea::layout_latex

(

)

const

MicroTeX: just run the LaTeX layout algorithms, do not draw.

measure_height_for_width()

void TeXView::TeXArea::measure_height_for_width ( int  width, int &  minimum_height, int &  natural_height  ) const

protected

The MicroTeX size logic, shared between the two toolkits.

The MicroTeX height-for-width computation, shared between gtkmm-3's get_preferred_height_for_width_vfunc and GTK4's measure_vfunc.

void TeXView::TeXArea::on_size_allocate ( Gtk::Allocation &  allocation )

overrideprotected

relayout_for_allocation()

void TeXView::TeXArea::relayout_for_allocation ( int  width, int  height  )

protected

The re-layout that follows a new allocation, shared between gtkmm-3's on_size_allocate and GTK4's size_allocate_vfunc.

set_latex()

void TeXView::TeXArea::set_latex

(

const std::string &

latex

)

MicroTeX: set the LaTeX string and replace/substitute so that MicroTeX can render it (but do not actually render).

update_image()

void TeXView::TeXArea::update_image

(

std::shared_ptr< TeXEngine::TeXRequest >

content

)

Propagate a change in the TeXRequest (i.e.

a new LaTeX string) through to the visible widget.
