From f80075be4ebb9c5fe00c24b8c7638fad23267424 Mon Sep 17 00:00:00 2001 From: Keith Packard Date: Thu, 29 May 2014 14:03:58 -0700 Subject: java: Refactor AltosFlightDisplay units and font update handling Make AltosFlightDisplay explicitly implement AltosFontListener and AltosUnitsListener interfaces to make everyone use the same API. Then, actually go implement units listeners so that changing units updates all of the active displays immediately Signed-off-by: Keith Packard --- altosui/AltosLanded.java | 67 +++++++++++++++++++++++++++++++++--------------- 1 file changed, 46 insertions(+), 21 deletions(-) (limited to 'altosui/AltosLanded.java') diff --git a/altosui/AltosLanded.java b/altosui/AltosLanded.java index 707d8fcc..bb52fe2b 100644 --- a/altosui/AltosLanded.java +++ b/altosui/AltosLanded.java @@ -27,10 +27,13 @@ import org.altusmetrum.altosuilib_2.*; public class AltosLanded extends JComponent implements AltosFlightDisplay, ActionListener { GridBagLayout layout; - public class LandedValue { + public abstract class LandedValue implements AltosFontListener, AltosUnitsListener { JLabel label; JTextField value; - void show(AltosState state, AltosListenerState listener_state) {} + AltosUnits units; + double v; + + abstract void show(AltosState state, AltosListenerState listener_state); void reset() { value.setText(""); @@ -46,7 +49,8 @@ public class AltosLanded extends JComponent implements AltosFlightDisplay, Actio value.setText(s); } - void show(AltosUnits units, double v) { + void show(double v) { + this.v = v; show(units.show(8, v)); } @@ -54,17 +58,24 @@ public class AltosLanded extends JComponent implements AltosFlightDisplay, Actio show(String.format(format, v)); } - public void set_font() { + public void font_size_changed(int font_size) { label.setFont(Altos.label_font); value.setFont(Altos.value_font); } + public void units_changed(boolean imperial_units) { + if (units != null) + show(v); + } + void hide() { label.setVisible(false); value.setVisible(false); } - public LandedValue (GridBagLayout layout, int y, String text) { + public LandedValue (GridBagLayout layout, int y, AltosUnits units, String text) { + this.units = units; + GridBagConstraints c = new GridBagConstraints(); c.weighty = 1; @@ -89,6 +100,10 @@ public class AltosLanded extends JComponent implements AltosFlightDisplay, Actio layout.setConstraints(value, c); add(value); } + + public LandedValue (GridBagLayout layout, int y, String text) { + this(layout, y, null, text); + } } String pos(double p, String pos, String neg) { @@ -151,12 +166,12 @@ public class AltosLanded extends JComponent implements AltosFlightDisplay, Actio void show (AltosState state, AltosListenerState listener_state) { show(); if (state.from_pad != null) - show(AltosConvert.distance, state.from_pad.distance); + show(state.from_pad.distance); else show("???"); } public Distance (GridBagLayout layout, int y) { - super (layout, y, "Distance"); + super (layout, y, AltosConvert.distance, "Distance"); } } @@ -164,10 +179,10 @@ public class AltosLanded extends JComponent implements AltosFlightDisplay, Actio class Height extends LandedValue { void show (AltosState state, AltosListenerState listener_state) { - show(AltosConvert.height, state.max_height()); + show(state.max_height()); } public Height (GridBagLayout layout, int y) { - super (layout, y, "Maximum Height"); + super (layout, y, AltosConvert.height, "Maximum Height"); } } @@ -175,10 +190,10 @@ public class AltosLanded extends JComponent implements AltosFlightDisplay, Actio class Speed extends LandedValue { void show (AltosState state, AltosListenerState listener_state) { - show(AltosConvert.speed, state.max_speed()); + show(state.max_speed()); } public Speed (GridBagLayout layout, int y) { - super (layout, y, "Maximum Speed"); + super (layout, y, AltosConvert.speed, "Maximum Speed"); } } @@ -186,10 +201,10 @@ public class AltosLanded extends JComponent implements AltosFlightDisplay, Actio class Accel extends LandedValue { void show (AltosState state, AltosListenerState listener_state) { - show(AltosConvert.accel, state.max_acceleration()); + show(state.max_acceleration()); } public Accel (GridBagLayout layout, int y) { - super (layout, y, "Maximum Acceleration"); + super (layout, y, AltosConvert.accel, "Maximum Acceleration"); } } @@ -205,14 +220,24 @@ public class AltosLanded extends JComponent implements AltosFlightDisplay, Actio accel.reset(); } - public void set_font() { - lat.set_font(); - lon.set_font(); - bearing.set_font(); - distance.set_font(); - height.set_font(); - speed.set_font(); - accel.set_font(); + public void font_size_changed(int font_size) { + lat.font_size_changed(font_size); + lon.font_size_changed(font_size); + bearing.font_size_changed(font_size); + distance.font_size_changed(font_size); + height.font_size_changed(font_size); + speed.font_size_changed(font_size); + accel.font_size_changed(font_size); + } + + public void units_changed(boolean imperial_units) { + lat.units_changed(imperial_units); + lon.units_changed(imperial_units); + bearing.units_changed(imperial_units); + distance.units_changed(imperial_units); + height.units_changed(imperial_units); + speed.units_changed(imperial_units); + accel.units_changed(imperial_units); } public void show(AltosState state, AltosListenerState listener_state) { -- cgit v1.2.3
