<Swing Dev> [15] RFR JDK-8216329: Cannot resize CheckBoxItemMenu in Synth L&F with setHorizontalTextPosition

[Pankaj Bansal]

Hello Sergey,

<<So the problem is that we need to reinstall all UI  on "horizontalTextPosition" event?(what exact property is missing?)
No, this is not the issue. The issue is that the updateIcon method is not supposed to be called in SynthLookAndFeel. SynthMenuItemUI class has overridden installDefaults of BasicMenuItemUI class and it never calls the code in updateCheckIcon even when that code was part of BasicMenuItemUI installDefaults. WindowsMenuItemUI has not overridden installDefauls,  so this code is called for WindowsLookAndFeel.
The issue is that during the fix of [1], the changes were made in code which is called for all LookAndFeels, though the issue is only in WindowsLookAndFeel. The fix should have been specific to WindowsLookAndFeel.

<< It is not a big issue, but for such a fix we will need a proper specification and CSR, it is like adding a new method to the public class. It is preferable to try to fix it in some other way first.
I did not realize earlier that this can be done by making changes in WindowsMenuItemUI without calling the updateCheckIcon by moving the code in updateCheckIcon method in WindowsMenuItemUI class. I have made the changes for the same and all works fine. Also, I have removed the updateCheckIcon method from BasicMenuItemUI class as it is not needed.

It is not a big issue, but for such a fix we will need a proper specification and CSR, it is like adding a new method to the public class. It is preferable to try to fix it in some other way first.

So the problem is that we need to reinstall all UI  on "horizontalTextPosition" event?(what exact property is missing?)
