Example 1 with Break

use of com.xenoage.zong.core.format.Break in project Zong by Xenoage.

the class SystemSpacer method canAppend.

/**
 * Returns true, if the given measure can be appended to the currently computed system,
 * otherwise false.
 * It is not tested if there is enough vertical space, this must be done before.
 */

    // if a line break is forced, do it (but one measure is always allowed)
    Break br = scoreHeader.getColumnHeader(measureIndex).getMeasureBreak();
    if (br != null && br.getSystemBreak() == SystemBreak.NewSystem && false == isFirstMeasure)
        return false;

    // ok, append the measure
