getAboveFloatElementCursor

public static java.lang.Object[] getAboveFloatElementCursor(ElementCasePane reportPane,
                                            double evtX,
                                            double evtY)

Is above float element.(the return may be null).
The length of Object[] is 2, the first is FloatElement, the second is Cursor.
The object[] is null

caculateFloatElementLocations

public static double[] caculateFloatElementLocations(FloatElement floatElement,
                                     DynamicUnitList columnWidthList,
                                     DynamicUnitList rowHeightList,
                                     int verticalValue,
                                     int horizentalValue)

Gets float element locations. Returns[] {flaotX1, floatY1, floatX2, floatY2}.

caculateFloatElementLocations_withresolution

public static double[] caculateFloatElementLocations_withresolution(FloatElement floatElement,
                                                    DynamicUnitList columnWidthList,
                                                    DynamicUnitList rowHeightList,
                                                    int verticalValue,
                                                    int horizentalValue,
                                                    int resolution)

getEventColumnRow

public static ColumnRow getEventColumnRow(ElementCasePane reportPane,
                          double evtX,
                          double evtY)

Gets column and row which located on (evtX, evtY) peter:这个方法重复考虑到Frozen的情况,没有任何BUG,这个方法没有考虑那种不无限增大的情况.

参数:

reportPane - 当前的ReportPane

evtX - event x

evtY - event y

返回:

the event located column and row.

getEventColumnRow_withresolution

public static ColumnRow getEventColumnRow_withresolution(ElementCasePane reportPane,
                                         double evtX,
                                         double evtY,
                                         int resolution)

getAdjustEventColumnRow

public static ColumnRow getAdjustEventColumnRow(ElementCasePane reportPane,
                                double evtX,
                                double evtY)

Gets column and row which located on (evtX, evtY) peter:这个方法是调整过的Column,Row,不能小于0, 不能大于最大值,这个方法充分考虑了不无限增大的情况. 一般经常用这个方法, 对应的getEventColumnRow(...)反而不常用.

参数:

reportPane - 当前的ReportPane

evtX - event x

evtY - event y

返回:

the event located column and row.

getAdjustEventColumnRow_withresolution

public static ColumnRow getAdjustEventColumnRow_withresolution(ElementCasePane reportPane,
