[request] Input text field or input field that maintains formatting

Sorry, not with the current features on the script level.

But since we run on Java, you might try this (tested and works):
# make your own input function
def myInput(title):
    import javax.swing.JTextArea as JTextArea
    import javax.swing.JPanel as JPanel
    import java.awt.Dimension as Dimension
    import javax.swing.JOptionPane as JOptionPane

    ta = JTextArea("")
    ta.setPreferredSize(Dimension(50,50));
    myPanel = JPanel();
    myPanel.add(ta);

    if 0 == JOptionPane.showConfirmDialog(None, myPanel, title, JOptionPane.OK_CANCEL_OPTION):
        return ta.getText()
    else:
        return ""

# and use it like this
given = myInput("gimmi some text")
if given != "":
    print given
else:
    print "no input"

With Dimension(50,50) you set the size of the displayed text area (which may take content of any size).
This is a quick and dirty solution and might be beautified at your needs.

I will add an inputText() function to the scripting API.

this is a somewhat enhanced version:

def myInput(title, width = 10, lines = 5):
    import javax.swing.JTextArea as JTextArea
    import javax.swing.JPanel as JPanel
    import java.awt.Dimension as Dimension
    import javax.swing.JOptionPane as JOptionPane
    import javax.swing.BorderFactory as BF
    import java.awt.Color as COLOR

    textH = 16
    textW = 10
    inner = 5
    ta = JTextArea("")
    ta.setPreferredSize(Dimension(width*textW,lines*textH + inner*2));
    b0 = BF.createEmptyBorder(inner, inner, inner, inner)
    b1 = BF.createLineBorder(COLOR.BLACK)
    ta.setBorder(BF.createCompoundBorder(b1, b0))
    myPanel = JPanel();
    myPanel.add(ta);

    if 0 == JOptionPane.showConfirmDialog(None, myPanel, title, JOptionPane.OK_CANCEL_OPTION):
        return ta.getText()
    else:
        return ""

given = myInput("gimmi some text")
if given != "":
    print given
else:
    print "no input"

The text area now has a simple border.
You may specify the number of characters (width = 10 default) per line and the number of lines (lines = 5 default) (this is based on the assumption, that a character is 10x16 Pixel.

Awesome, that works great
One thing I wonder I don't know how it would be implemented in sikuli
It starts out with the dialogue focus on the OK button and if you tab twice you're into the JTextArea

Would it be hard to implement that if while in the JTextArea instead of it putting a tab in the JTextArea when you press it cycles back to the OK button and maybe a shift tab will actual do a tab inside the JTextArea or vice versa

thanks again for all your help :-)

Thanks RaiMan, that solved my question.

ctrl-tab works on both platforms FYI :D
