Example 1 with Meter

use of org.apache.pivot.wtk.Meter in project pivot by apache.

the class TerraMeterSkin method getPreferredHeight.

@Override
public int getPreferredHeight(int width) {
    Meter meter = (Meter) getComponent();
    int preferredHeight;
    if (meter.getOrientation() == Orientation.HORIZONTAL) {
        preferredHeight = getPreferredWidth(width);

        String text = meter.getText();
        if (text != null && text.length() > 0) {
            FontRenderContext fontRenderContext = Platform.getFontRenderContext();
            LineMetrics lm = font.getLineMetrics("", fontRenderContext);
            preferredHeight = (int) Math.ceil(lm.getHeight()) + 2;
        } else {
            preferredHeight = 0;
        }
        // If the meter has no content, its preferred height is hard-coded by the
        // class and is not affected by the width constraint
        preferredHeight = Math.max(preferredHeight, DEFAULT_HEIGHT);
    }
    return preferredHeight;
}

the class MeterTest method testListeners.

@Test

    meter.setPercentage(0.25);
    meter.setPercentage(0.5);
    meter.setPercentage(0.75);
    meter.setPercentage(1.0);
    // Now check for proper listener event counts
    assertEquals(percentChangeCount, 4);
    assertEquals(textChangeCount, 3);
    assertEquals(orientationChangeCount, 2);
}

Example 4 with Meter

use of org.apache.pivot.wtk.Meter in project pivot by apache.
