<Swing Dev> [9] Review request for 8165594 Bad rendering of Swing UI controls with Windows Classic L&F on HiDPI display

[Andrej Golovnin]

Hi Alexandr,

thanks! It looks much better now.

src/java.desktop/share/classes/com/sun/java/swing/plaf/windows/WindowsIconFactory.java

490                 if(isScaledGraphics){

Spaces are missed between 'if' and '(' and between ')' and '{'.

The empty lines 491, 520 and 522 are not needed and should be removed.


src/java.desktop/share/classes/javax/swing/plaf/basic/BasicArrowButton.java

240             if(SwingUtilities2.isScaledGraphics(g)){

Spaces are missed between 'if' and '(' and between ')' and '{'.

344                 xPoints = new int[]{mid, mid + size, mid - size};

The Java Style Guidelines [1] don't mention this. But I think there
should be a space between 'new int[]' and '{'. The lines 345, 356,
357, 366 and 367 are also affected.


src/java.desktop/share/classes/sun/swing/SwingUtilities2.java

2041     public static boolean isScaledGraphics(Graphics g) {

Have you considered to make this method a public API (move to the
SwingUtilities class), so that other Swing developers may use it too?

Radio buttons are still not ideal. Have you considered to enable AA
when painting HiDPI icons? On the other hand I'm not sure, whether we
should invest a lot of time into making Windows Classic L&f to look
perfect on HiDPI screens.
