Method Detail

addUserScaleChangeListener

public static void addUserScaleChangeListener(java.beans.PropertyChangeListener listener)

removeUserScaleChangeListener

public static void removeUserScaleChangeListener(java.beans.PropertyChangeListener listener)

setSystemScaleFactor

public static void setSystemScaleFactor(float sysScale)

setUserScaleFactorForTest

public static void setUserScaleFactorForTest(float value)

getFontScale

public static float getFontScale(float fontSize)

Returns:

the scale factor of fontSize relative to the standard font size (currently 12pt)

setUserScaleFactor

public static float setUserScaleFactor(float scale)

Sets the user scale factor. The method is used by the IDE, it's not recommended to call the method directly from the client code. For debugging purposes, the following JVM system property can be used: ide.ui.scale=[float] or the IDE registry keys (for backward compatibility): ide.ui.scale.override=[boolean] ide.ui.scale=[float]

Returns:

the result

sysScale

public static float sysScale()

Returns the system scale factor, corresponding to the default monitor device.

sysScale

public static float sysScale(java.awt.Component comp)

Returns the system scale factor, corresponding to the device the component is tied to. In the IDE-managed HiDPI mode defaults to sysScale()

sysScale

public static float sysScale(java.awt.GraphicsConfiguration gc)

Returns the system scale factor, corresponding to the graphics configuration. In the IDE-managed HiDPI mode defaults to sysScale()

scale

public static float scale(float f)

Returns:

'f' scaled by the user scale factor

scale

public static int scale(int i)

Returns:

'i' scaled by the user scale factor

scaleIcon

public static <T extends JBScalableIcon> T scaleIcon(T icon)

Scales the passed icon according to the user scale factor.

See Also:

ScaleType.USR_SCALE

scaleFontSize

public static int scaleFontSize(float fontSize)

getSystemFontData

public static Pair<java.lang.String,java.lang.Integer> getSystemFontData()

sysScale

public static float sysScale(java.awt.Graphics2D g)

Returns the system scale factor, corresponding to the graphics. For BufferedImage's graphics, the scale is taken from the graphics itself. In the IDE-managed HiDPI mode defaults to sysScale()

sysScale

public static double sysScale(ScaleContext context)

isHiDPI

public static boolean isHiDPI(double scale)

Returns whether the provided scale assumes HiDPI-awareness.

isUsrHiDPI

public static boolean isUsrHiDPI()

Returns whether the ScaleType.USR_SCALE scale factor assumes HiDPI-awareness. An equivalent of isHiDPI(scale(1f))
