In Options/settings menu, you can set your preferred browser and default KW/h cost. This value must be written as pure number (with no currency symbol) and is used in devices cost statistic.

Starting with this version a flag has been added to allow you to save main window position and size on exit.

In version 1.2 a combo box has been added to choose your date format. You can also create a new one but the string has to follow standard date format. Valid letters are:


Era designator

Virtually any combination of these letters and keyboard signs can be used to create new data format some samples for date 15 Jan 2011:

the string dd/MM/yy gives as result 15/01/11

and the string dd)MM\yyyy gives as result 15)01\2011 (really no one use this format)

while d-MMM, yy gives as result 15-Jan, 11

Warning: the last form with a single d gives back and accept in input only one digit for dates under day 10 (eg. 3-Jan, 11 for day 3). Also all signs are required in input as you specify so you can't input 15-Jan 11 (without comma) or 15/Jan, 11 (with slash instead of minus sign).

About Date Bugs: Nyagua try to retrieve from the current (your) locale three standard formats for date (short date/med date/ long date) In US format they should be (for example): M/d/yy 8/22/12, MMM d,yyyy Aug 22,2012, MMMM d,yyyy August 22,2012
These formats are retrieved automatically from java code as SHORT/MEDIUM and LONG date. A dd/M/YY format has been added as a most used standard to be sure there is at least a valid format.

This way to retrieve date formats is showed in official Java code samples but with some locale an error occur as follow:
Exception in thread "main" java.lang.IllegalArgumentException: Illegal pattern character 'j'
at java.text.SimpleDateFormat.compile(SimpleDateFormat.java:845)

This is a JAVA VM translation bug. Eg. the JVM for sk returns some j and n chars that are invalid for date format.

Measure Units settings

Allow to choose your preferred measure units.

This preference is automatically used in the utilities.

If the tick is active in “Use in program" then the units will also be displayed on forms in the program.

The option "Use in reports" enable the display of units in the reports.

Note: up to version 3.1 these options that affect only the form and the reports related to the aquarium as the other masks are already using specific units.

It It's important to know that changing the units does NOT automatically adjust the values. That's because they are stored as simple numbers. So to avoid misinterpretation it is good practice not to change the units after saving the values.

Reports settings

Some reports / statistics are implemented in some forms the buttons to start reports and/or statistics are over the toolbar (eg statistic button: ). Stay over the buttons to get tootips help or feel free to try it :-). Some reports as Expenses Report, FishBase Report and PlantsBase Report need a browser to be showed. The default browser is Firefox but if you need to change it You can do in Options/settings window.

Other settings related to reports are:
