textfield

I have a simple TextField that binds to the state 'location' like this, TextField("Search Location", text: $location) I want to call a function each time this field changes, something like this: TextField("Search Location", text: $location) { self.autocomplete(location) } However this doesn't work. I know that there are callbacks, onEditingChanged - however this only seems to be triggered when the field is focussed. How can I get this function to call each time the field is updated? You can create a binding with a custom closure, like this: struct ContentView: View { @State var location:

I'm trying to make a Suduko game in JavaFX but I can't figure out how to only allow one letter to be entered. Would the answer to this to be to call the textfield and do: myTextField.setOnKeyPressed(e -> { if (!myTextField.getText().length().isEmpty()) { // Somehow reject the key press? } } The above way won't work with copy pasting... or tons of other things, etc. Using key press listeners like this seems like an AWFUL idea. There must be something better? Is there a property of text fields to allow only certain characters to be inputted, or only allow certain number of characters to be

On the Internet, I found very useful class, using which I can restrict TextField. I encountered a problem, where my TextField can contain only one '.' character. I suspect that I can handle this by writing an appripriate regex and set it as a restriction on the instance of that class. I use the following regex: "[0-9.-]", but it allows as many dots as the user types. May I ask you to help me to configure my TextField so that no more than one '.' is allowed. import javafx.beans.property.IntegerProperty; import javafx.beans.property.SimpleIntegerProperty; import javafx.beans.property

HI All, I know this is bit strange question, but please suggest. I want to create a link on website url content in input type"text" field not any other html tag,Is it possible and if yes how. Regards & Thanks Amit Flak DiNenno This is unfortunately not possible in the way you've asked it in HTML 4 or below. Even with HTML5 which has several new INPUT TYPEs, including URL, it only does validation and has some other useful functions, but won't give you want you want. You might look for some jQuery plugins that can help you do this, most use the same principals behind Rich Text or other online

I wrote an application with JavaFX which will only be usable with keyboard's arrows. So I prevented MouseEvent on Scene's stage, and I "listen" to KeyEvents. I also switched off focusability of all nodes : for(Node n : children) { n.setFocusTraversable(false); Now I have some textfields, checkboxes, and buttons. I would like to change the state of my input controls (textfield, checkbox,..) programatically: for example I would like to enter the textfield to edit the content programatically. So my question is: how to enter in a non-focus-traversable textfield? Because textfield.requestFocus();

I want to provide the user with a hint on what he needs to enter into my text field. However, when I set the value, it does not disappear once a user clicks on the text field. How can you make it disappear? <form action="input_password.htm"> <p>Username:<br><input name="Username" value="Enter username.." type="text" size="20" maxlength="20"></p> </form> You'd need attach an onFocus event to the input field via Javascript: <input type="text" onfocus="this.value=''" value="..." ... /> With a bit of javascript <input value="Enter username.." onfocus="if (this.value == 'Enter username..') this
