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.

Am 12. Juni ist es soweit…ich werde bei mir zu Hause den inoffiziellen JUG SummerEvent veranstalten…

Dabei geht es im wesentlichen darum sich zu treffen, ein paar Bierchen zusammen zu trinken, etwas auf den Grill zu schmeissen und natürlich auch ein wenig Java zu coden (natürlich nur wer Lust dazu hat). Desweiteren steht ein Tischkicker, evtl. eine Carrerabahn (muß ich erst aufbauen) und ein Trampolin zur Verfügung für diejenigen von Euch, welche sich sportlich betätigen möchten.

Da wir bei uns zu Hause natürlich keinen geeigneten Raum haben um Vorträge zu präsentieren, würde es sich ja anbieten diesen Event für sog. Lightning Talks zu nutzen. Dabei kann jeder der Interesse hat ja etwas vorbereiten, was er den anderen in max. 10 Minuten zeigen möchte.

Ihr könnt Euch auch hier bei Xing als Teilnehmer eintragen falls Ihr mögt…

Zur Veranstaltung:

Wer: jeder der Lust und Zeit hat sich ein wenig auszutauschen

Wo: Bei mir zu Hause (Westfalenstrasse 93, 48165 Münster GoogleMaps)

Wann: ab 11 Uhr könnt Ihr bei mir eintrudeln, Ende offen

Mitzubringen sind:

– Grillfleisch

– Notebook (falls benötigt)

– wenn mögich Salate und Brot

Getränke, Grill etc. sponsor ich…
