With a Swift UITextField the default behavior when not editing is to ellipse the most recently entered text if the text is too long to fit in the space allowed for the text field. As shown in this image:
When you begin to edit the text field, the text shifts left to make the most recently entered text visible. As shown in this image:
How can I achieve this effect when I am not editing the text field? I would like the most recently viewed text to always be visible no matter whether or not the user is currently editing the text field. If the text is too long for the space provided for the text field, it should not display the oldest text.
This could be easily achieved using UITextView if that suits other requirements:
let textView = UITextView()
textView.textContainer.maximumNumberOfLines = 1
textView.textContainer.lineBreakMode = .byTruncatingHead

I want write password of the root to the shell, but without move the cursor when i write it.
prompt = {"Senha de Administrador: "}; your textdefaults = {""}; your text`rowscols = [1,25];

I can't, for example, change the color text to the background tex, as alternative
There are several ways to hide text while editing it, depending on what you mean by "hiding" the text and the context in which you are editing the text. Here are a few options:
If you are editing text in a word processor or text editor, you can use the "hidden" text formatting feature to hide the text. This will cause the text to be invisible while you are editing, but it will be visible when the document is printed or exported.
If you are writing code and want to hide certain lines or blocks of code while you are editing, you can use a code folding feature to collapse the code so that it takes up less space in the editor.
If you are writing text on a website and want to hide it from view, you can use the "display: none" CSS style to hide the text. This will cause the text to be invisible to users, but it will still be present in the HTML code of the page.
How to set position label in TextFormField in outlineborder?
i want set text position. Because, label prefer to bottom not center in border
According to the documentation for the label
Text that describes the input field.
When the input field is empty and unfocused, the label is displayed on
top of the input field (i.e., at the same location on the screen where
text may be entered in the input field). When the input field receives
focus (or if the field is non-empty), the label moves above (i.e.,
vertically adjacent to) the input field.
So, basically this is the behavior for the label. If you want something else you have to make it on your own ( using a Stack widget with a TextField and a Text ). But with this solution you have to treat the focus properties as well on your own.

I would like to have a text box and a button in my GUI. When the button is pressed, a history window will come up, and if the user selects a previous entry the text that they have highlighted in the edit box will be overwritten.
It should work like copy-pasting, whatever is selected in the history window should be pasted over what is selected, or the new text should be added wherever the cursor is.
Is there any way in Matlab to do this? Is it possible to access what is highlighted in an edit box?
With vanilla Matlab this isn't possible. It appear that Mathworks is in the process of expanding what they support with GUIs (survey 1, survey 2), but as of yet they don't allow this.
One possible workaround is using findjobj.m, by Yair Altman. He discusses edit boxes in this post
You can trace findjobj.m for your text box to find 1 or 2 lines of code that are needed so you don't have to carry around all 3,400 lines of it.
Then all you really need to do is get the selected indices and work from there.
javaHandle = findjobj(editBoxHandle);
startSelect = get(javaHandle,'SelectionStart');
endSelect = get(javaHandle,'SelectionEnd');
Once you have the indexes of what text is selected, it becomes almost trivial to replace that text with the new text.
text = editBoxHandle.String;
editBoxHandle.String = [text(1:startSelect) newText text(endSelect:end)];
One thing to note, when the user clicks the button the text box will lose focus, and it will no longer be clear what text is selected. You can remedy this by giving focus back to the text box, and re-selecting what was selected in the button's callback.
uicontrol(editBoxHandle); %Give focus to the edit box, selecting the entire text
javaHandle.select(startSelect,endSelect); %select/highlight the correct stuff
This will highlight the text that will be replaced with the users selection
I'm working on a swift project and have a Text Field. The user can input a string into this field. Currently if the user types too much then the string scrolls horizontally on the one line. How do I build a text field where once the first line is full it adds a line.

UITextField is one-line only.
You can replace your UITextField with UITextView in your storyboard. They are editable and selectable by default.
I have a UITextField which I created programmatically. This text field is used to input a time. The placeholder text is "00:00:00.000". When the text field is tapped, a number pad will appear. Ideally, I want the gray place holder text to remain as the user types. As they enter a number, it replaces the gray zeros in the place holder text and skips over the colons and period (leaving the format intact without the user entering any punctuation). If it is not possible to keep the place holder text and replace it as the user types, I would like the punctuation to automatically be entered.
Thanks in advance!
iOS has a UIDatePicker control for this, if you want to go the way you are going then you will have handle all the user input your self.
