Android Mirroring/Device Frame/Get Preferred Size

AndroidMirroring/DeviceFrame/GetPreferredSize

screen size: 1855, 1056
canvas size: 1080, 1920
frame size: 1121, 1938
canvas size 는 screenshot 에 의한 image 의 size 임
frame.height > screen.height: frame.height = (int) (0.9 * screen.height); 950.4
frame.width > screen.width: frame.width 1121
frame.width > 1080 + inset + toolbar + scrollbar
frame.height > 1920 + inset + infopane + scrollbar 950.4
다른 프로그램을 참조할 것
screen size, canvas size 둘 다 변수이므로, 잘 생각해야 할 듯함.
public class DeviceFrame extends JFrame
- public DeviceFrame(Application app, final AndroidDevice device)
  - pack(); 에 의해 getPreferredSize method 가 call 된다.

call ¶

Dimension frame = super.getPreferredSize();
canvas, img 는 ImageCanvas 의 오브젝트임.
Dimension canvasSize = canvas.getPreferredSize();
- image 가 null 이면 Dimension(200, 300) 리턴
- skinBackgroundImage 가 있으면
  - Dimension(scale(skinBackgroundImage.getWidth(null)), scale(skinBackgroundImage.getHeight(null)))
- Dimension(scale(image.getWidth()), scale(image.getHeight()))
Dimension sz = img.getPreferredSize();

canvas ¶

class ImageCanvas extends JComponent
- public void setScreenshot(ScreenImage image)
  - repaint();
- protected void paintComponent(Graphics g)
- public Dimension getPreferredSize()
  - return new Dimension(scale(image.getWidth()), scale(image.getHeight()));

Settings ¶

private final Preferences applicationPreferences;
set
- askBeforeQuit, imageFormat, askBeforeScreenshot, scale, hideEmulators,
- upsideDown, landscape, autoShow
private void set(String name, String value)
private void set(String name, int value)
private void set(String name, boolean value)

        public int getPreferredScale() {^M
                return applicationPreferences.getInt("scale", 100);^M
        }^M
^M
        public void setPreferredScale(int value) {^M
                set("scale", value);^M
        }^M

integer division ¶

int x = ...;
int y = ...;
double value = ((double) x) / y;
