Hello Stackeroverflowers,
i'd like to ask how can i change a RadioButton Dot?
I need to define 3 RadioButtons with 3 different Colors to show a state.
Do i have to work with Css?
Would be perfect if anyone could tell me how can i realize that ?
A Example would be:
#FXML
public RadioButton redState = new RadioButton();
.
.
.
redState.setDotColor(red);
or in Fxml to define the Color static:
style="-fx-dot-color: rgb(255,0,0);"
I hope everyone understood my Plan.
It's only about colorize the Dot in a javafx RadioButton.
I'm thankfull for every Answer.
I haven't tested this, but try
redState.getStyleClass().add("red-radio-button");
(or do this in FXML if you prefer).
And then in an external css file
.red-radio-button .dot {
-fx-mark-highlight-color: red ;
-fx-mark-color: red ;
}

I have a Vaadin 7 Grid and I would like to set a color to a specific column.
Grid grid = new Grid(container);
grid.setColumnOrder("column1","column 2","column 3");
Use one of the many column renderers. Easiest is probably the HTMLRenderer.
Example:
grid.addColumn("column1", String.class).setRenderer(new HtmlRenderer());
grid.addRow("data for column1", "data for column2", ...,
"<h1 style="background-color:Red;">data for column3</h1>");
See also: https://vaadin.com/docs/v7/framework/components/components-grid/#components.grid.generatedcolumns
This piece of code actually worked for me.I have been using Java 8 ,
Grid.setCellStyleGenerator((Grid.CellStyleGenerator) cellReference ->{
cellReference.getGrid().getHeaderRow(rowIndex: 0).getCell("column name").setStyleName("bg-blue");
}
Note :- bg-blue is the css rule mentioned in CSS file .
I'm trying to remove the down arrow from a combobox. All the solutions I have found just make the arrow disappear, for example this one.
Is there a way to remove completely the space where the arrow appears and fill the box just with the text of the selected choice?
If you want to completely elimnate the arrow & arrow button space, you can try with the below custom ComboBox.
The below code is setting the arrow button and arrow nodes size to 0 and asking to rerender the comboBox. The null check is to let this changes apply only once.
public class MyComboBox<T> extends ComboBox<T>{
Region arrowBtn ;
#Override
protected void layoutChildren() {
super.layoutChildren();
if(arrowBtn==null){
arrowBtn= (Region)lookup(".arrow-button");
arrowBtn.setMaxSize(0,0);
arrowBtn.setMinSize(0,0);
arrowBtn.setPadding(new Insets(0));
Region arrow= (Region)lookup(".arrow");
arrow.setMaxSize(0,0);
arrow.setMinSize(0,0);
arrow.setPadding(new Insets(0));
// Call again the super method to relayout with the new bounds.
super.layoutChildren();
}
}
}
UPDATE :
Based on the suggestion of #kleopatra, we can get the same behaviour using css as well (without the need to create a new class for ComboBox).
.combo-box .arrow-button,
.combo-box .arrow{
-fx-max-width:0px;
-fx-min-width:0px;
-fx-padding:0px;
}
The below image will tell you the difference of a normal combox box and this custom combo box. The left one is the normal comboBox, you can see the list cell when inspecting with ScenicView. The right one is the custom one. The list cell is completely occupied suppressing the arrow space.
I would like to set the caret color for all JavaFX text inputs (e.g. TextField, TextArea, the ones in ComboBox:editable, DatePicker, etc...)
I found this Stackoverflow answer: How to change the caret color in JavaFX 2.0?
... and an example on GitHub.
The first one does change the text and the caret color which is not good. The second one extends the TextFieldSkin class, which is already better, but how can I use it in CSS?
Any help is appreciated.
UPDATE 1:
I found the following CSS style property for JavaFX controls: -fx-skin.
This would theoretically allow me to set a custom skin class (-fx-skin: "package.MySkin";), however, the skin class just isn't used!
The class looks like the following:
package gui;
…
public class MyTextFieldSkin extends TextFieldSkin
{
public MyTextFieldSkin(TextField tf) {
super(tf);
System.out.println("MyTextFieldSkin constructor called!");
ReadOnlyObjectWrapper<Color> farbe = new ReadOnlyObjectWrapper<>(Color.green);
caretPath.strokeProperty().bind(farbe);
caretPath.setStrokeWidth(1.5);
}
}
… and is set in CSS like that:
.text-field {
-fx-skin: "gui.MyTextFieldSkin";
}
What am I doing wrong? I looked at the source code of AquaFX, and they are doing it the same way as me!
After a bit of try & error, I solved the problem in the following way:
I gathered all TextFields and controls that have TextFields in them (like ComboBox, DatePicker and so on) inside a container recursively (in deference of TitledPane, ScrollPane, SplitPane and TabPane, because they don't publish their children in getChildren(), so one has to call the getContent() method of the individual classes and scan through it).
After I had all the TextField controls, I looped over them and changed their Skin with the following code:
public class MyTextFieldSkin extends TextFieldSkin {
public MyTextFieldSkin(TextField tf)
{
super(tf);
ReadOnlyObjectWrapper<Color> color = new ReadOnlyObjectWrapper<>(Color.RED);
caretPath.strokeProperty().bind(color);
}
}
Then I just had to call
textfield.setSkin(new MyTextFieldSkin(textfield));
and that was about it.
Cheers
I have a TextField styled by changing styleClass when its value is valid/invalid but there is a great problem. When the value becomes valid I still should change the TextField once more to make the styleClass be applied. I tried with applyCss() method just after, but it didn't work :(.
if(!valid){
field.getStyleClass().add("invalid-field");//Works excellent
} else {
field.getStyleClass().remove("invalid-field");//Doesn't work up to the time textProperty doesn't change once again
field.applyCss();
One common cause of these bugs is that you may have added the "invalid-field" style class more than once. (Remember, getStyleClass() returns a List<String>, not a Set<String>.) So you should probably take steps to make sure the style class is only added once, or take steps to remove all occurrences when you remove it.
I like to do both (where I come from, we call this a "belt and braces approach").
ObservableList<String> styleClasses = field.getStyleClass();
if(!valid)
if( ! styleClass.contains("invalid-field")){
styleClass.add("invalid-field");
}
} else {
// remove all occurrences:
styleClass.removeAll(Collections.singleton("invalid-field"));
}
I'm new to vaadin. I came across with a bug that full name is not visible in twin-column component's values. I have very long names inside the left side of the twin-column. I increased the width of the component much as I can. But still some lines are there that not visible full name.
I tried to add some css, even that didn't work.
.v-select-twincol-options .v-select-twincol-break-word{word-wrap: break-word;}
I tried with this css line. Any wrong in here? Or any idea to solve this. Please help me on this..
Thank you in advance.
private TwinColSelect createTemplateSelectTwinColumn()
{
TwinColSelect twinColSelect = new TwinColSelect("Related Templates");
twinColSelect.setNullSelectionAllowed(true);
twinColSelect.setMultiSelect(true);
twinColSelect.setImmediate(true);
twinColSelect.setSizeFull();
Collection<File> templates = getTemplates();
Collections.sort((List<File>) templates, new Comparator<File>()
{
#Override
public int compare(final File f1, final File f2)
{
return f1.getName().compareTo(f2.getName());
}
});
for (File file : templates)
{
twinColSelect.addItem(file.getNodeId());
twinColSelect.setItemCaption(file.getNodeId(), file.getName());
}
return twinColSelect;
}
Method where I'm creating the twinColumn inside a FormLayout
Vaadin's TwinColSelect eventually results in two standard HTML option list controls in the DOM; see the DOM of this example: http://demo.vaadin.com/book-examples/book/#component.select.twincolselect.basic
word-wrap is, however, not possible on option list items.
Consider creating your "own" TwinColSelect from two Vaadin tables. Vaadin tables are much more flexible regarding CSS styling.
