Examples with Painter javax.swing.Painter used on opensource projects

Example 1 with Painter

use of javax.swing.Painter in project jdk8u_jdk by JetBrains.

the class SynthPainterImpl method paintBackground.

private void paintBackground(SynthContext ctx, Graphics g, int x, int y, int w, int h, AffineTransform transform) {
    // if the background color of the component is 100% transparent
    // then we should not paint any background graphics. This is a solution
    // for there being no way of turning off Nimbus background painting as
    // basic components are all non-opaque by default.
    Component c = ctx.getComponent();
    Color bg = (c != null) ? c.getBackground() : null;
    if (bg == null || bg.getAlpha() > 0) {
        Painter backgroundPainter = style.getBackgroundPainter(ctx);
        if (backgroundPainter != null) {
            paint(backgroundPainter, ctx, g, x, y, w, h, transform);
        }
    }
}

Example 2 with Painter
