Class: Toybox.Graphics.Dc

Inherits:

Toybox.Lang.Object

• Toybox.Lang.Object
• Toybox.Graphics.Dc

Overview

This class represents a device context.

It provides methods to perform drawing operations on the device.

Note:

You should never directly instantiate a Dc object, or attempt to render to the screen outside of an onUpdate call.

Example:

Draws a blue rectangle using direct pixel parameters.

using Toybox.Graphics;
function onUpdate(dc) {
    dc.setColor(Graphics.COLOR_BLUE, Graphics.COLOR_BLACK);
    dc.fillRectangle(100, 100, 100, 100);
}

Example:

Draws a red circle using direct pixel parameters.

using Toybox.Graphics;
function onUpdate(dc) {
    dc.setColor(Graphics.COLOR_RED, Graphics.COLOR_BLACK);
    dc.fillCircle(50, 100, 75);
}

Example:

Draws "Hello World" in the center of the screen using calls to the Device Context (dc).

using Toybox.Graphics;
function onUpdate(dc) {
    dc.setColor(Graphics.COLOR_BLACK, Graphics.COLOR_TRANSPARENT);
    dc.drawText(
        dc.getWidth() / 2,                      // gets the width of the device and divides by 2
        dc.getHeight() / 2,                     // gets the height of the device and divides by 2
        Graphics.FONT_LARGE,                    // sets the font size
        "Hello World",                          // the String to display
        Graphics.TEXT_JUSTIFY_CENTER            // sets the justification for the text
                );
}

Example:

Clears the screen of device with background color (Graphics.COLOR_BLACK).

using Toybox.Graphics;
function onUpdate(dc) {
    dc.setColor(Graphics.COLOR_BLACK, Graphics.COLOR_BLACK);
    dc.clear();
}

API Level 1.0.0

Instance Method Details

clear() as Void

Erase the screen using the background color.

Note:

Starting form version 3.1.0, COLOR_TRANSPARENT will also be honored as background color, which will cause the value of pixels in the clip region to be replaced by COLOR_TRANSPARENT. For example, this can be used to clear the transparent overlay layer so animation background is visible.

API Level 1.0.0

clearClip() as Void

Reset the drawable area to the full area of the Dc.

Since:

API Level 2.3.0
