Method Detail

setMinMax

public void setMinMax(float minValue,
                      float maxValue)

Description copied from class: GralWidget

Sets the border of the value range for showing. If it is a ValueBar, for exmaple, it is the value for 0% and 100% This routine is empty per default, should be overridden if it is necessary.

Specified by:

setMinMax in interface GralSetValue_ifc

Overrides:

setMinMax in class GralWidget

setBorderAndColors

public void setBorderAndColors(java.lang.String[] sParam)

Associates values to level and color.

• The first and the last String is the min and max values.
• All odd Strings (0, 2, ...) are values, the following String is the color.
• For example {"-100","red","0","green","100","orange", "200"}

The example shows a value bar from -100 to 200. A value < 0 is shown red, >100 is shown organge. This form of parameter allows a simple preparation from a simple String, for example

 String param = "-100,red,0,green,100,orange,200";
 String[] sParam = param.tokenize(",");

Parameters:

sParam - Even number of Strings.

setValue

public void setValue(float value)

Sets the bar and its color. A refresh of graphic is only done if the value change forces a change of pixel positions of the value bar. Less changes of value does not force refresh.

Specified by:

setValue in interface GralSetValue_ifc

Overrides:

setValue in class GralWidget

Parameters:

value - This routine may be overridden by some specialized widgets.
