JavaFx TextFlow does not resize on GridPane on change of value - javafx

I have a TextFlow in a GridPane, when I change its value to a wider one it does not increase its width accordingly on display but truncates. I am a newbie at Java and I've probably missed something simple.
Initial value is built as follows;
TextFlow mhText = new TextFlow();
// Loop to build TextFlow
for(Card c : myGame.me.playerHands.get(0).handCards) {
Text text = new Text(c.cardText(false) + " ");
if(c.redSuit()) {text.setFill(Color.RED);}
mhText.getChildren().add(text);
}
playerGrid.add(mhText, 1, pgRow)
Then later it is rebuilt...
mhText.getChildren().clear();
for(Card c : myHand.handCards) {
Text text = new Text(c.cardText(false) + " ");
if(c.redSuit()) {text.setFill(Color.RED);}
mhText.getChildren().add(text);
}
Result screenshot
You can just see from the screenshot that only a dot from the additional 3rd 'card' is showing, I think due to truncation. I've tried using setPrefWidth and setMinWidth without success.
I can solve the problem by removing and re-adding the TextFlow on the GridPane,
playerGrid.getChildren().remove(mhText);
playerGrid.add(mhText, 1, myHandRow);
but I would be surprised if this is the right way, any advice is welcome.

Bold Text Parts in ControlsFX Notification

I'm trying to write bold text inside the body of a Notification.
Notifications.create()
.title("My Title")
.text("This is <bold>text</bold>")
.showInformation();
As far as I can tell there's only the .text("my text") method to set the text of a Notification.
However I'd like to use a TextFlow in there to modify certain parts of a text.
I've also tried to use CSS for this but that only lets me change to overall appearances of the Notification as setting specific text through CSS is explicitly not supported.
My question now is: Is there a way to style parts of a text inside a Notification differently?
Got it working now.
The solution is to use .graphic(Node node). If you still want to display an Image at the left side you need to put everything in a Pane and add some padding.
I yoinked the original image from here.
BorderPane borderPane = new BorderPane();
borderPane.setLeft(new ImageView(Controller.class.getResource("/dialog-information.png").toExternalForm()));
TextFlow textFlow = new TextFlow();
textFlow.setPadding(new Insets(15, 0, 5, 5));
Text text1 = new Text("This is ");
Text text2 = new Text("bold");
text2.setStyle("-fx-font-weight: bold");
textFlow.getChildren().addAll(text1, text2);
borderPane.setRight(textFlow);
Notifications.create()
.title("My Title")
.graphic(borderPane)
.hideAfter(Duration.seconds(10))
.show();
It is important to use .show() and not .showInformation/Error/Warning() because that would override the BorderPane.

How to resize QListWidgetItem according to it's content?

I'm adding a QListWidgetItems to a QListWidget. Is there any way to set the size of the QListWidgetItem according to it's content data?
QSize size(50, 20);
QListWidgetItem* newItem1 = new QListWidgetItem();
newItem1->setText("short text");
newItem1->setSizeHint(size);
listWidget->addItem(newItem1); //listWidget is previously created
QListWidgetItem* newItem2 = new QListWidgetItem();
newItem2->setText("this is a very long text");
newItem2->setSizeHint(size);
listWidget->addItem(newItem2);
Text of newItem1 is displayed without any problem. But the newItem2 text is not fully displayed. It only shows few characters and then "..." as text elide. How to show the complete text without the elide? I want to set the size according to the size of item's data without setting any constant numbers.
I simply copy/pasted your code, removed setSizeHint() function call for both items and added some of mine. Here's working code:
QListWidgetItem* newItem1 = new QListWidgetItem();
newItem1->setText("short text");
ui->listWidget->addItem(newItem1);
QListWidgetItem* newItem2 = new QListWidgetItem();
newItem2->setText("this is a very long text");
ui->listWidget->addItem(newItem2);
ui->listWidget->setFixedSize(ui->listWidget->sizeHintForColumn(0) + ui->listWidget->frameWidth() * 2,
ui->listWidget->sizeHintForRow(0) * ui->listWidget->count() + 2 * ui->listWidget->frameWidth());
As you can see, both items are fully displayed.
Actually I have accidentally enabled uniformItemSizes for the QListWidget. When I disable that, QListWidgetItems were automatically resized according to it's content.

Qt QTableView 1 line vertical size

I have the following to add a QTableView to a QWidget:
QVBoxLayout *vLayout = new QVBoxLayout(this);
QTableView *tableView = new QTableView;
tableView->horizontalHeader()->setStretchLastSection(true);
tableView->verticalHeader()->setStretchLastSection(true);
tableView->verticalHeader()->setVisible(false);
vLayout->addWidget(tableView);
This widget will use model which load data from MySQL... And there is only one line of content, so I would like to make the view just height enough to show one line. How to approach this issue?
I had the same problem and found that this works best:
const auto height = table.horizontalHeader()->sizeHint().height() + table.rowHeight(0);
table.setMinimumHeight(height);
table.setMaximumHeight(height);
You force the table to keep the exact size specified by you: the header size + the size of a single row.

calculating Spark TextArea width

I am treating a spark TextArea as text input(by setting heightInLines="1"). The TextArea is part of an mxml component and I want to resize the component when the text is changed.
I haven't been able to use textArea.measureaText(textArea.text) to get line metrics and use it. I get this error "Parameter antiAliasType must be non-null."
Is there any way to get the width of a TextArea which it is going to consume at runtime for a particular string or a particular TextFlow?
A little ugly but works for me:
var uiText:UItextField = new UITextField();
// if you have custom text style on the TextArea then set it the same of this uitextfield
uiText.setTextFormat("bla bla bla");
uiText.text = "This is the text that I want the size for";
var textW:Number = uiText.textWidth;
var textH:Number = uiText.textHeight;
// then we need to consider also the border of the text area and the paddings
// try read the padding values and border sizes using getStyle(...)
myTextArea.width = textW+2*borderW+paddingL+paddingR;
myTextArea.height = textH+2*borderH+paddingT+paddingB;
That should be all

Styling UITextField

I've been playing around with different methods of determining at runtime the width of a "label" so that I can resize the "label" because I don't want it to truncate. I've finally found an easy solution through UITextField which allows me to set the .autoSize which is great! However, now I'm trying to "style" (simply adjust font and font size) of the UITextField but it seems that I have to do it manually with '.htmlText' (which I'll gladly accept if that is the ONLY way).
I'm using the .text to set the value of the label.
My test case involves a HBox (I'm actually using a Grid but they should be the same and I've done testing on both):
I style the HBox and the style carries through to the UITextField. I don't believe this will work for me because I have other components inside that I need to style differently.
I've tried: UITextFormat and TextFormat (I see that the .htmlText being updated accordingly but the output doesn't update. Then I noticed that whenever I called hbox.addChild(myUITextField) it would override the .htmlText
I've tried setting the style with myUITextField.setStyle("fontSize", 20) before and/or after the call to addChild neither of which made an impact on the display as per what I noted above.
Changes are being made but they seem to be overrided when I add it to the display.
So what do I need to do in order to style the UITextField aside from manually setting it along with my contents in .htmlText? Solutions not using UITextField is fine as long as there is some easy way of not truncating the text.
EDIT: I want to just do textField.setStyle('fontSize', 20) and expect that every time I change the text, I wouldn't need to use HTML to go with it (so I can just do textField.text = 'something else' and expect that it will still have a font size of 20). This is what I meant by not using .htmlText (sorry if I wasn't clear before).
2nd EDIT: I guess I should present the whole issue and maybe that'll clarify what I did wrong or couldn't achieve.
My intent is to have a Grid and add text into it. I do not want it to wrap or scroll so I add it to the next row in the Grid when the current row's children total width exceeds some number. In order to add it to the next row, I need to be able to calculate the width of the text. I would like to be able to style that text individually based on cases and there might be other components (like a TextInput). Essentially what I'm trying to accomplish is "Fill in the Blank".
I've included code to show what I'm currently doing and it works somewhat. It might be un-related to the original issue of styling but I can't figure out how to adjust the distance between each UITextField but aside from that this fits what I would like to accomplish. Relevant to the question is: I would like to change the way I style each UITextField (currently setting .htmlText) into something a bit straightforward though like I previously mentioned I'll gladly accept using .htmlText if that's the only solution.
So I have a Grid with x Rows in it and in each row, I have exactly one GridItem. Based on the input, I add UITextField and TextInput into the GridItem going on to the next GridItem when necessary. If you have a better way of doing so then that would be better but I guess what I really want is to find a different way of styling.
Also another problem, I'm not sure of the exact way to add a TextField into the display. I tried:
var t : TextField = new TextField();
t.text = "I'm a TextField";
hBox.addChild(t); // doesn't work
//this.addChild(t); // doesn't work either
But I get the following error:
TypeError: Error #1034: Type Coercion failed: cannot convert flash.text::TextField#172c8f9 to mx.core.IUIComponent.
Here's what I have that's working.

After about 8 hours of searching for a solution to what would seem to be such a simple issue I FINALLY stumbled on your posts here... Thankyou!!!
I have been stumbling around trying to get TextField to work and had no Joy, Label was fine, but limited formatting, and I need to be able to use embedded fonts and rotate. After reading the above this finally worked for me:
var myFormat:TextFormat = new TextFormat();
myFormat.align = "center";
myFormat.font = "myFont";
myFormat.size = 14;
myFormat.color = 0xFFFFFF;
var newTxt:UITextField = new UITextField();
newTxt.text = "HELLO";
addChild(newTxt);
newTxt.validateNow();
newTxt.setTextFormat(myFormat);
The order of addChild before the final 2 steps was critical! (myFont is an embedded font I am using).
One again... a thousand thankyou's...

EDIT BASED ON THE ASKERS FEEDBACK:
I didn't realize you wanted to just apply one style to the whole textfield, I thought you wanted to style individual parts. This is even simpler for you, won't give you any trouble at all :)
var textFormat: TextFormat = new TextFormat("Arial", 12, 0xFF0000);
myText.setTextFormat(textFormat);
Be aware that this sets the style to the text that is in the TextField, not necessarily future text you put in. So have your text in the field before you call setTextFormat, and set it again every time you change it just to be sure it stays.
It's probably best if you use a normal TextField as opposed to the component. If you still want the component you may need to call textArea.validateNow() to get it to update with the new style (not 100% sure on that one though) Adobe components are notoriously bad, and should be avoided. :(
To see all available options on the TextFormat object see here
END EDIT ---------
This is easy enough to just do with CSS in a normal old TextField.
var myCSS: String = "Have some CSS here, probably from a loaded file";
var myHTML: String = "Have your HTML text here, and have it use the CSS styles";
// assuming your textfield's name is myText
var styleSheet: StyleSheet = new StyleSheet();
styleSheet.parseCSS(myCSS);
myText.autoSize = TextFieldAutoSize.LEFT;
myText.styleSheet = styleSheet;
myText.htmlText = myHTML;

The reason you have a problem adding Textfield to containers is that it doesn't implement the IUIComponent interface. You need to use UITextField if you want to add it. However, that's presenting me with my own styling issues that brought me to this question.
A few things I know:
TextField is styled using the TextFormat definition, and applying it to the textfield. As Bryan said, order matters.
setStyle does nothing on IUITextField, and the TextFormat method doesn't seem to work the same as in normal TextFields. (Edit #2: Ahah. You need to override the "validateNow" function on UITextFields to use the setTextFormat function)
To autosize a TextArea, you need to do something like this (inheriting from TextArea):
import mx.core.mx_internal;
use namespace mx_internal;
...
super.mx_internal::getTextField().autoSize = TextFieldAutoSize.LEFT;
this.height = super.mx_internal::getTextField().height;
Found this code on, I think, on StackOverflow a while back. Apologies to the original author. But the idea is that you need to access the "mx_internal" raw textfield.
Text and TextArea have wrapping options. (Label does not). So if you set the explicit width of a Text object, you might be able to size using the measuredHeight option and avoid truncation.
(edit: That was #4, but stackoverflow parsed it into a 1...)
