Member Function Documentation

◆ draw_gutter()

void CodeInput::exp_input_tv::draw_gutter	(	const Cairo::RefPtr< Cairo::Context > &	cr,
		int	h )

Paint the coloured bar down the left-hand side of the cell, on top of the TextView's own rendering.

Paint the coloured bar down the left-hand side of an input cell, which indicates the cell type and whether it is running.

Drawn on top of the TextView's own rendering by both toolkits.

◆ get_preferred_width_for_height_vfunc()

void CodeInput::exp_input_tv::get_preferred_width_for_height_vfunc	(	int	height,
		int &	minimum_width,
		int &	natural_width ) const

overridevirtual

◆ get_request_mode_vfunc()

Gtk::SizeRequestMode CodeInput::exp_input_tv::get_request_mode_vfunc ( ) const

overridevirtual

◆ handle_key_press()

bool CodeInput::exp_input_tv::handle_key_press	(	guint	keyval,
		Gdk::ModifierType	state )

Key handling, shared between the toolkits.

Handle a key press.

Returns true when the key was consumed; false lets the TextView's own default handling run. gtkmm-3 reaches it through the on_key_press_event vfunc, GTK4 through an Gtk::EventControllerKey, which has the same contract.

Returns true when the key was consumed; false means the TextView's own default handling should run. Shared between gtkmm-3's on_key_press_event vfunc and GTK4's Gtk::EventControllerKey, which has the same true/false contract.

◆ measure_width_for_height()

bool CodeInput::exp_input_tv::measure_width_for_height	(	int &	minimum_width,
		int &	natural_width ) const

Width logic for LaTeX cells, shared between the toolkits; returns false when the base class should decide instead.

LaTeX cells are forced to the window width.

Shared between gtkmm-3's get_preferred_width_for_height_vfunc and GTK4's measure_vfunc; returns false when the caller should defer to the base class.

◆ on_draw()

bool CodeInput::exp_input_tv::on_draw ( const Cairo::RefPtr< Cairo::Context > & cr )

overridevirtual

◆ on_focus_entered()

void CodeInput::exp_input_tv::on_focus_entered ( )

Side effects of focus and pointer motion, likewise shared.

The side effects of gaining focus, losing focus and pointer motion.

Shared between gtkmm-3's vfuncs and GTK4's Gtk::EventControllerFocus / Gtk::EventControllerMotion, neither of which gtkmm-3 wraps.

◆ on_focus_in_event()
