Hi! I have been trying class TextMorph out for making an editable textfield for my GUI. One thing I can't figure out is how to make the text "grow" horisontaly when you write instead of verticaly. I am after the behavior similar to the spotlight search text field in mac. If you write loads of text the oldest text "dissapear" (visualy) on the left hand. I have tried autoFit: false and wrapFlag: false without any desired results. Doesn't TextMorph contain this functionality from start? Do I need to subclass and write the function from scratch? Many thanks in advance! Marcus

I think you would have to subclass to be able to get the behavior you describe. TextMorph is very confusing and hard to make behave the way you want. Karl

Hi Marcus, I have done this in Maui. I had to subclass TextMorph (MauiStringEditor) and override #handleKeystroke: to dynamically adjust the extent. So, when you start typing in Maui, the text morph is small, just big enough to hold about one character. Then, as you continue typing, it will take the first-line out to a fair one-line width (1/7th the width of the World) before expanding its height to two-lines.
As you keep typing, it maintains that width until it starts to get too tall. "Too tall" is where its width:height is < 4:3; i.e., it maintains a 4:3 width to height ratio as you keep typing.
I put quite a bit of thought and work into this, if you would like to check it out, if at least for an example of dynamically growing your TextMorph, load "Maui" from SqueakSource into a 3.8 image and then look at the MauiStringEditor class (a subclass of TextMorph).
You can type MauiStringEditor new openInHand to play with it.
Cheers, Chris

... until it reaches its #maxExtent (half screen) at which point the scroll bar appears.. Kinda cool! :)
And it does have a bug or two, with cut and paste I think..

Can we make TextMorph use the Maui growing behavior? I find it much more intuitive and useful. I often cringe at the current "keep the width constant and grow vertically" behavior. I pulled the Class out into a GrowableTextMorph, but I think the behavior should just be folded into TextMorph. If necessary, we could even set the default maxWidth to simulate how TextMorph currently works for backward-compatibility.
What do you all think?

TextMorph is a very generic widget,so I can see the need to maintain the existing functionality, however I think it would be a nice option / preference. One thing I always wanted to improve on was the way it automatically resizes; instead of just one-pixel at a time, to be able to "zoom" more quickly to the optimal size. However, my attempts to do so invariably caused an oscillation between "too small" and "too large".
