No change to ListView when text is entered in filter TextField

wish helps you I need to learn new ways introduced to newer versions of JavaFX. I thought about what I actually wanted to do, wrote it out on paper, and wrote it to the best of my ability/current knowledge.
Here is the working code, still with a ChangeListener in the initialize method, and OnAction still removed from FXML file. Now, when I type a character, the respective plant shows up, and shows the original upon hitting backspace.

     public void filterPlantList(String oldValue, String newValue) {

    ObservableList<Plant> filteredList = FXCollections.observableArrayList();
    if(filterInput == null || (newValue.length() < oldValue.length()) || newValue == null) {
        plantList.setItems(observablePlantList);
    }
    else {
        newValue = newValue.toUpperCase();
        for(Plant plants : plantList.getItems()) {
            String filterText = plants.getName();
            if(filterText.toUpperCase().contains(newValue)) {
                filteredList.add(plants);
            }
        }
        plantList.setItems(filteredList);
    }
}
@Override
public void initialize(URL fxmlFileLocation, ResourceBundle rb) {

    //add Listener to filterInput TextField
    filterInput.textProperty().addListener(new ChangeListener() {
        public void changed(ObservableValue observable, Object oldValue, Object newValue) {
            filterPlantList((String) oldValue, (String) newValue);
        }
    });

How do I 'listen' to text that is being entered in the textfield?

around this issue How do I get my script to listen to any text that is being typed within a text field? I used the class '.ops' and tagged it to various select fields and a text field. I'm only able to detect the changes in the select fields, but not able to detect the changes in the text field unless I press 'Enter'on the keyboard. , You can specify multiple events here:

$(document).on('change keyup', '.ops', function() {

How to limit text in textfield when entered text through speech

hop of those help? Assuming you want the entered text to be truncated to a maximum of 50 characters regardless of the method of entry, you can do something like this:

- (BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string {
    if(textField==self.optionATextField || textField==self.optionBTextField ||textField==self.optionCTextField) {
        NSString *newText = [textField.text stringByReplacingCharactersInRange:range withString:string];
        if (newText.length < 50) {
            // Text length is still OK, let it through
            return YES;
        } else {
            // The new text is too long - truncate and set the shorter value
            newText = [newText substringToIndex:50];
            textField.text = newText;

            return NO;
        }
    } else {
        return YES; // do whatever you need here
    }
}

Textfield.text entered should have a specific format

To fix the issue you can do I have a textfield and I want the text to be entered in it in a format: aa #### 1234 I know this should be done in shouldChangeCharactersInRange delegate method of textfield.nut I am not able to understand that how condition will be implemented on each character.Kindly give your suggestions. in advance! , An expression that can be helpful to validate your needs might be:

^[a-z]{2}\s\d{4}\s\d{4}$

- (BOOL)textField:(UITextField *)textField shouldChangeCharactersInRange:(NSRange)range replacementString:(NSString *)string
{
    NSError *error = NULL;
    NSRegularExpression *regex = nil;

     NSMutableString *combinedText = [textField.text mutableCopy];
    [combinedText replaceCharactersInRange:range withString:string];

    switch (combinedText.length) {
        case 1:
        case 2:
            regex = [NSRegularExpression regularExpressionWithPattern:[NSString stringWithFormat:@"^[a-z]{%ld}", (long)combinedText.length] options:NSRegularExpressionCaseInsensitive error:&error];
            break;
        case 3:
            regex = [NSRegularExpression regularExpressionWithPattern:@"^[a-z]{2}\\s" options:NSRegularExpressionCaseInsensitive error:&error];
            break;
        case 4:
        case 5:
        case 6:
        case 7:
            regex = [NSRegularExpression regularExpressionWithPattern:[NSString stringWithFormat:@"^[a-z]{2}\\s\\d{%ld}", (long)combinedText.length - 3] options:NSRegularExpressionCaseInsensitive error:&error];
            break;
        case 8:
            regex = [NSRegularExpression regularExpressionWithPattern:@"^[a-z]{2}\\s\\d{4}\\s" options:NSRegularExpressionCaseInsensitive error:&error];
            break;
        case 9:
        case 10:
        case 11:
        case 12:
            regex = [NSRegularExpression regularExpressionWithPattern:[NSString stringWithFormat:@"^[a-z]{2}\\s\\d{4}\\s\\d{%ld}$", (long)combinedText.length - 8] options:NSRegularExpressionCaseInsensitive error:&error];
            break;
        default:
            return false;
    }

    if(error) return false;        

    NSUInteger numberOfMatches = [regex numberOfMatchesInString:combinedText options:0 range:NSMakeRange(0, combinedText.length)];
    return numberOfMatches > 0 || string.length == 0;
}

Flutter textfield that auto expands when text is entered and then starts scrolling the text when a certain height is rea

Tag : dart , By : hlpimfalling

around this issue I've tried many configurations of the Flutter TextField but can't figure out how to build this one.

Container(
    child: new ConstrainedBox(
        constraints: BoxConstraints(
            maxHeight: 300.0,
        ),
        child: new Scrollbar(
            child: new SingleChildScrollView(
                scrollDirection: Axis.vertical,
                reverse: true,
                child: new TextField(
                    maxLines: null,
                ),
            ),
        ),
    ),
)
