Hi again,

these days i’ve got the problem that i need to add a version number to the SteelSeries java component library and to be honest i had no idea how to realize it.

So after a short internet research i figured out that there is the ability to add version information to the manifest file that’s included in a jar file.

If you do not know what a manifest is or how it is embedded in the jar file you will find a detailled description here.

Now that i knew where to put the version information the question was how to get Netbeans adding this information automaticaly to the manifest file during the build process. Well Netbeans is using Ant under the hood to build your projects and because i knew ant build scripts from using the Hudson Continues Integration server it was easy to achieve this.

First of all you have to locate the build.xml file in your Netbeans projects folder. Simply open it in Netbeans itself and you will see something like this… weiterlesen

Hi there,

this is just to inform you that there is a updated version of the Java Swing component library „SteelSeries“ available.

I added 10 more components…

There are radial bargraphs which you could see below

 

In addition to these i added another version of the Radial2 component which is called Radial2Top

The last component i added is called RadialCounter. I saw this kind of component during a visit of a german u-boat

where it was used to visualize the depth of the boat.

 

In addition to the new components there a some more modifications like colored tickmarks etc.

AutoConversion EditText component:

Yesterday i created a Java Swing textfield component that autoconverts a given value into a selectable unit which could be useful.

In the evening i got the idea to port this component to Android and see if it will work there.

Just as a short note…if you are a Java developer you should take a look into Android…it’s sooooo nice, porting the component tooks me not more than 2 hours (and i’m not really into Android development).

Here is the result:

 

 

 

 

 

 

 

 

 

 

 

So you could type in a value with the unit of your choice and after leaving the field the value will be converted into the EditText „base unit“.

I changed the units with special characters like µ, Å, ² and ³ to u, A, 2 and 3 which leads to units like:

um  <=>  µm

A <=>  Å

m2  <=>  m²

m3  <=>  m³

and so on…

The upper spinner will select the type of unit you would like to use.

The middle spinner will select the current base unit for the textfield.

The lower spinner will adjust the number of decimals for the textfield.

Because it displays the unit directly in the textfield there’s no need for a additional label for the unit.

Well again this is nothing very fancy or gui related but it was a nice challange for me so i decided to share it with you… AutoConversionField.zip

AutoConversion textfield component:

If you drive a motorized stage of a microscope you often have to handle coordinates in a unit like millimeter [mm]. But it might happen that the sample in your microscope is only in the range of microns [µm].

So would it not be nice to directly type in the coordinates in µm and the textfield would automaticaly convert the unit into [mm] ?

This would increase the workflow a lot because you do not have to think about conversion of units. There seems to be countries that are using inches and people living there might like to type in coordinates in inches instead of millimeters..etc…

For this reason i created a little component that extends a standard javax.swing.JTextField and is now able to do the conversion. You could also use the conversion alone without the textfield to create some kind of unit converter…it’s up to you.

Here are a few screenshots of a demo app that uses the component:

So you could type in a value with the unit of your choice and after leaving the field or pressing enter the value will be converted into the textfields „base unit“.

The upper combobox will select the type of unit you would like to use (it supports angle, area, length, mass, temperature, time at the moment but one could easily add more units to it).

The middle combobox will select the current base unit for the textfield.

The lower combobox will adjust the number of decimals for the textfield.

Because it displays the unit directly in the textfield there’s no need for a additional label for the unit.
