What is the best way to retrieve user-input text from a text field on Submit button press? I am having issues with the listener, because it doesn't return anything (located in my gui class). I need to somehow retrieve what the user inputs, then return to the main class, and decide from there what to do with the user input. an example code would be nice!
You can attach a listener with your button and override its actionPerformed(). Inside actionPerformed(), you can retrieve the value entered in the text field.
Something like this :
button.addActionListener(new ActionListener (){
public void actionPerformed(ActionEvent evt) {
String text = textField.getText();
}
};)

When I fill the fields with values and submit, empty field validation still fires randomly and not everytime. As you can see in the image, the fields are non empty , still validations are fired.
I have noticed, usually selenium takes time to enter details, but in my case, as soon as the page loads, it quickly starts filling the fields speedily. Its unusually fast.
I am using Selenium , specflow framework and page object pattern and page factory.
My code for entering the text field is below :
public static void FillTextBox(IWebElement webElement,string value)
{
webElement.Click();
webElement.Clear();
webElement.SendKeys(value);
}
Please help me with this.
If you look up the definition of the onBlur event, you will find:
The onblur event occurs when an object loses focus.
So you have to shift focus to another element after you fill in each text box.
public static void FillTextBox(IWebElement textField, string value, IWebElement otherElement) {
textField.SendKeys(value);
otherElement.Click(); // this will have to be some other element on your page
}
i have developed a simple calculator like in windows calculator,
but unlike in windows calculator, after clicking any button, the focus on that button is still there on the particular clicked button.
so how to never get focus for all buttons on calculator form ... ?
i don't think that it will better to write loose focus code on every button's click event ... so any better solution ?
Without seeing any code of yours, I am going to assume that you have a text box that displays the numbers pressed by the user, so you need to set the focus to the text box once a user clicks a button, like this:
TextBox1.Focus()
Note: If your text box is not named TextBox1, then change the name to whatever your text box is actually named.
Instead of a standard button use an instance of a NoFocusButton class derived from the Standard button. In this class override the ShowFocusCues property and return always false.
Form f = new Form();
// Need to add manually the buttons to your form unless you build a customcontrol
NoFocusButton b = new NoFocusButton();
b.Text = "ClickMe";
f.Controls.Add(b);
f.Show();
// Class derived by the Button control, it is identical but the
// property that control the drawing of the Focus rectangle returns FALSE
// tricking the WinForm system to avoid to draw the focus rectangle
class NoFocusButton : System.Windows.Forms.Button
{
protected override bool ShowFocusCues
{
get
{
return false;
}
}
}

I am working on a Compact Framework application. This particular hardware implementation has a touchscreen, but its Soft Input Panel has buttons that are simply too small to be useful. There are more than one form where typed input is required, so I created a form with buttons laid out like a keypad. The forms that use this "keypad" form are modal dialogs. When a dialog requiring this "keypad" loads, I load the "keypad" form as modeless:
private void CardInputForm_Load(object sender, EventArgs e)
{
...
keypadForm = new KeypadForm();
keypadForm.Owner = this;
keypadForm.SetCallback(keyHandler);
keypadForm.Show();
}
The SetCallback method tells the "keypad" form where to send the keystrokes (as a Delegate).
The problem I'm having is that the modeless "keypad" form does not take input. It is displayed as I expect, but I get a beep when I press any of its buttons, and its caption is grayed-out. It seems like the modal dialog is blocking it.
I've read other posts on this forum that says modal dialogs can create & use modeless dialogs. Can anyone shed light on this situation? Is there a problem with my implementation?
I found the answer: Set the keypad form's Parent property, not its Owner property, to the form instance wanting the keystrokes. The keypad dialog's title bar stays grayed out, but the form is active.
private void CardInputForm_Load(object sender, EventArgs e)
{
// (do other work)
keypadForm = new KeypadForm();
keypadForm.Parent = this;
keypadForm.Top = 190; // set as appropriate
keypadForm.Show();
}
Be sure to clean up when done with the parent form. This can be in the parent's Closing or Closed events.
private void CardInputForm_Closing(object sender, CancelEventArgs e)
{
// (do other work)
keypadForm.Close();
keypadForm.Dispose();
}
There are two panels on the keypad form, one with numerals and one with letters and punctuation that I want. There is also an area not on a panel that is common to both, containing buttons for clear, backspace, enter/OK, and cancel. Each panel has a button to hide itself and unhide its counterpart ('ABC', '123', for example). I have all the buttons for input on the keypadForm fire a common event. All it does is send the button instance to the parent. The parent is responsible for determining what action or keystroke is desired. In my case I named the buttons "btnA", "btnB", "btn0", "btn1", "btnCancel", etc. For keystrokes, the parent form takes the last character of the name to determine what key is desired. This is a bit messy but it works. Any form wishing to use the keypad form inherits from a base class, defining a method for callback.
public partial class TimeClockBase : Form
{
public TimeClockBase()
{
InitializeComponent();
}
// (other implementation-specific base class functionality)
public virtual void KeyCallback(Button button)
{
}
}
The click event on the keypad form looks like this.
private void btnKey_Click(object sender, EventArgs e)
{
// play click sound if supported
(Parent as TimeClockBase).KeyCallback(sender as Button);
}
The method in the parent form looks like this.
public override void KeyCallback(Button button)
{
switch (button.Name)
{
case "btnCancel":
// setting result will cause form to close
DialogResult = DialogResult.Cancel;
break;
case "btnClear":
txtCardID.Text = string.Empty;
break;
// (handle other cases)
}
}
I'm using NSPredicateEditor in my project. One of my rows has 2 popup buttons and a text field on the right. If I have something typed in the text field, when I select a different menu item from either of the popup buttons then the text in the text field is deleted. That seems to be the default behavior and I don't want that text deleted. I've tried everything I can think of and can't seem to handle this. Any ideas how to change this behavior?
You could save the data by using NSUserDefault it will save and load the data (It won't delete your data unless the user does).
Access the text fields via the row template's templateViews property.
This allows you to get the custom values that have been entered into the textfield. Save the value when it changes.
class YourCustomRowTemplate : NSPredicateEditorRowTemplate {
func printTextFieldValues() {
let templateViews = super.templateViews
for view in templateViews {
if let textField = view as? NSTextField {
let text = textField.stringValue
print("Text in the texfield is: \(text)")
}
}
}
}
You can set the values the same way, by subclassing NSPredicateEditorRowTemplate and overriding the templateViews method.
I have a Dojo form that does not contain a submit button. Instead, I added an onkeypress handler to calls a method when Enter is pressed. The problem I am having is that when I hit enter before blurring off the current field, the _process method thinks that field is empty.
Or in other words: type in field1. hit tab. type in field2. hit enter. field2 is blank unless i click off the field or shift-tab back.
Any ideas?
dojo.connect(dijit.byId("fkrform"),"onKeyPress",function(e) {
if (e.keyCode == dojo.keys.ENTER) {
_process();
}
and the method it calls:
function _process()
{
var field1 = dijit.byId("field1").value;
var field2 = dijit.byId("field2").value;
alert(username);
alert(password);
...do stuff...
}
The fields are of dojoType: dijit.form.TextBox, and the form is: dijit.form.Form
Use dijit.byId('field1').get('value') instead of directly try to access the property "value". In your example you saved the value in the variable field1 and field2 and in the alert you use the variable username and password could be the answer why you don't get anything. But you still should use the get method to get a property instead of directly access the property.
When you press "Enter" your form will submit. So you need to connect to the "onSubmit" event on the form, instead of onkeyPress or onKeyUp.
The first example i created prints the value of the input box on every key someone pressed in the console.
http://jsfiddle.net/a8FHg/
But what you really wanted was hooking into the submit. I modified the example. The new example connects to "onSubmit" and creates an alert box with the text of the user input.
http://jsfiddle.net/a8FHg/1/
For completness if jsfiddle doesn't work some day. You JavaScript should looks like this.
dojo.ready(function(){
var form = dijit.byId('form');
var box = dijit.byId('box');
var submit = function(event) {
dojo.stopEvent(event);
alert("User input was " + box.get('value'));
};
dojo.connect(form, 'onSubmit', submit);
});
Assuming your form in your HTML has the id form and your box have the id box.
