Я не могу изменить цвет Java Swing JScrollBar. Я искал и много читал об этом. Я пытаюсь использовать файл XML, чтобы определить цвета, используя внешний вид Synth для Swing. Для кнопки это работало нормально, но для полосы прокрутки не работает вообще.
Я надеялся, что смогу прикрепить файлы к этому вопросу, но, похоже, не смогу. Я буду рад выслать вам файлы.
Спасибо заранее. --- Алан
Вот содержимое файла XML:
<synth>
<!-- Style that all regions will use -->
<style id="backingStyle">
<!-- Make all the regions that use this skin opaque-->
<opaque value="TRUE"/>
<font name="Dialog" size="12"/>
<state>
<!-- Provide default colors -->
<color value="#F5DEB3" type="BACKGROUND"/>
<color value="black" type="FOREGROUND"/>
</state>
</style>
<bind style="backingStyle" type="region" key=".*"/>
<!-- Scroll bar track style -->
<style id="scrollBarTrackStyle">
<state>
<color value="red" type="BACKGROUND"/>
<color value="blue" type="FOREGROUND"/>
</state>
</style>
<bind style="scrollBarTrackStyle" type="REGION" key="ScrollBarTrack" />
<!-- Scroll bar thumb style -->
<style id="scrollBarThumbStyle">
<state>
<color value="white" type="BACKGROUND"/>
<color value="yellow" type="FOREGROUND"/>
</state>
</style>
<bind style="scrollBarThumbStyle" type="REGION" key="ScrollBarThumb" />
<!-- Scroll bar style -->
<style id="scrollBarStyle">
<state>
<color value="red" type="BACKGROUND"/>
<color value="blue" type="FOREGROUND"/>
</state>
</style>
<bind style="scrollBarStyle" type="REGION" key="ScrollBar" />
</synth>
