Whenever I open my JavaFX program, I there is a blue box around the first item in a TableView. Once the user clicks away, it's gone. Is there a way to remove it in a custom css file?
I've tried setting -fx-focus-color in .root and .table-row-cell (and much more that I can't remember) but nothing has worked.
I couldn't change the color to transparent but I was able to hide it by using
.table-row-cell:focused{
-fx-background-insets: 0;
}

I need to make a GUI in javafx where the buttons shape is custom made with a stylesheet
I use -fx-shape: "SVG Path"; to make the shape of my button
And sceneBuilder to make the GUI and if you need to know i use netbeans as my ide
Now when I make the custom form i want to only be able to click on that and not around it where the button is invisible
I have tried to use padding but i dont think that is the way
So if you look at this picture which is in scenebuilder
https://imgur.com/a/11dRR2G
you can see the white form which is what i want to be clickable
not the whole rectangle that you can see is lighted up
Ok this is not the direct answer to your question but a workaround on your Problem.
In you case i would just take the image which looks like that button and add a setOnMouseClickedEventListener
like this-
ImageView img = new ImageView("https://imgur.com/a/11dRR2G");
img.setPickOnBounds(false); // disables click on transparent areas
img.setOnMouseClicked((MouseEvent e) -> {
//do something
});
I have a ToggleGroup of ToggleButtons that should have the same style when unselected but each a different style when selected or hovered. I already found how this works with colors:
.my-toggle-button{
-fx-background-color: grey;
}
.my-toggle-button:hover{
-fx-background-color: -fx-mycolor;
}
.my-toggle-button:selected{
-fx-background-color: -fx-mycolor;
}
In my program, I can now set -fx-mycolor dynamically:
button.setStyle("-fx-mycolor: "+color);
where button is one of many ToggleButtons and color is a dynamically generated String.
This works just as expected: Each button has its own color when hovered over and keeps it when selected. If a different button gets selected, the previously selected button in the ToggleGroup snaps back to grey.
Now what I want is to do this with background images. I tried using
.toggle-button-fret-nonzero:selected{
-fx-background-image: url(-fx-myimage);
}
and then set it in Java via setStyle("-fx-myimage: "+image) but this doesn't work (CSS tries to load an image named -fx-myimage).
How can I achieve the behaviour demonstrated with colors for images?
I already tried to use setStyle("-fx-background-image: url("+image+");") directly on certain mouse-events like hovering or clicking but that's not what I want because then the button does not snap back to grey when another button is selected.
I would also like to avoid to define CSS-classes for every possible button since they are many.
EDIT: I solved the issue by using setStyle("-fx-background-image: url("+image+");") method and manually iterating over every button on every click, resetting the background-image accordingly. This works fine now, it's just that it feels like a hack since it's basically reimplementing the functionality of a ToggleButton...
I've started to learn Javafx and I happened upon this "strange" feature. I've made a simple window with two buttons. When I press one of them a blue stroke appears and stays there until I press the other button. I can't find any logical use of this other than knowing which button was pressed last. Even from a UX perspective, it doesn't make sense. I've tried somehow to "deactivate" it throught CSS but no luck. Is there any solution for this?
It's hard to tell what you are searching for without the code.
But I think you are referring to the visual marker for the currently focused menu item. This function is used in situations where the user hit's the "Tab"-Key to navigate through your menu items.
You can disable this feature for items by unchecking the "Focus Traversable" option in the "Properties" Tab. This will also disable the tab navigation!
There is already a thread that has a solution for exactly this topic. See:Remove Focus Box Around TextField
It talks about disabling the focus color using css, while keeping the tab navigation feature by using this css styling rule:
-fx-focus-color: transparent;
(Source: Uluk Biy's answer in the linked topic)
The blue outline around controls in JavaFX is there to indicate which control has focus.
Focus indicators are a common idiom used across different UI frameworks, not specific to just JavaFX. In a traditional mouse/keyboard based input setup, there needs to be some indication of where a keystroke will be sent when a key is pressed. Imagine there are multiple fields on a form, a few text fields and a couple of buttons. If the user types some characters - how does the system know into which text field to insert the characters? Similarly if the user presses return to activate a button, which button will get activated? The answer is that the button or field which currently has focus will receive the input. The focus can be changed usually by pressing the tab key to tab to a new field or pressing on a different field with the mouse. However, even though the system knows that which field has focus, it is important to provide feedback to the user to let the user know which field has focus. That way when the user types, they have some idea of where there input will be directed.
What you see with a blue outline around a button in JavaFX is a visual indicator to note that the button has focus and, if you press space, that button's action will be triggered and not some other button. When you click the mouse on another button it will both trigger the other button's action and transfer focus to that button, so if you subsequently press space, the last clicked button will be actioned again.
The focus color for a controls in JavaFX that are using the default modena.css stylesheet which comes with JavaFX 8, can be controlled by a couple of css properties which you can override in the user stylesheet for your application (by defining the properties in the .root {} css style class:
/* A bright blue for the focus indicator of objects. Typically used as the
* first color in -fx-background-color for the "focused" pseudo-class. Also
* typically used with insets of -1.4 to provide a glowing effect.
*/
-fx-focus-color: #039ED3;
-fx-faint-focus-color: #039ED322;
So, for instance, you could remove all focus colors from your application using:
.root {
-fx-focus-color: transparent;
-fx-faint-focus-color: transparent;
}
However, removing focus color indicators would probably make your application much less intuitive and more difficult to understand.
Let's look at a simple form in JavaFX:
The blue ring around the text input field for User Name indicates that text input will go into that field.
Is there a proper way to disable the focus ring only from my project's buttons?
If you want to disable focus feedback only for buttons and for all buttons in a project and also not effect other controls, then you can define a stylesheet rule for that:
.button {
-fx-focus-color: transparent;
-fx-faint-focus-color: transparent;
}
Note: I still don't recommend doing this even if other frameworks you use do not provide focus rings for buttons.
This will override the default focus coloring for buttons defined in the default JavaFX 8 modena.css stylesheet. You do not need to (nor should you) modify the modena.css stylesheet to override values in it. You can just redefine the values using a more specific CSS selector rule within your application's stylesheet. If you need to understand how CSS selectors work, there are numerous resources on the web you can search for and read. Oracle provide a getting started tutorial on how you can set a custom CSS style for a scene. The relevant code line is to add your user stylesheet to your scene:
scene.getStylesheets().add(
MyApplication.class.getResource(
"my-stylesheet.css"
).toExternalForm()
);
I'm not sure this is even possible. I've looked around on google a bit and found next to nothing on this subject. I like being able to stylize labels to make them look engraved or embossed in the CSS style sheet using the InnerShadow and DropShadow effects. I've tried the same on buttons but it doesn't effect the text, it just applies it directly to the button.
What would be the CSS I would need to use to apply the InnerShadow and/or DropShadow effects to the text of a button or toggle button?
Om further comments in the FXExperience: Styling FX Buttons with CSS page, it is mentioned that
the #ID Text has been changed to #ID LabeledText. I just confirmed that on JavaFX 8.
I think the best way to do this is to add a label into your button and stylize your label
How can I remove the small expand effect when I click on a JavaFX button? And also how can I make it work like an menu button (when I press it to remain in focused state untill I press another "menu" button). Is there a way to group nodes into the same focus?
Three questions for the price of one ;-)
How can I remove the small expand effect when I click on a JavaFX button?
When you click the button it has focus, when it has focus, it is surrounded by the focus ring, which makes it slightly larger. This effect is triggered via css.
Default css is in caspian.css found in jfxrt.jar in your JavaFX runtime install.
Relevant extract is here:
.button {
-fx-skin: "com.sun.javafx.scene.control.skin.ButtonSkin";
-fx-background-color: -fx-shadow-highlight-color, -fx-outer-border, -fx-inner-border, -fx-body-color;
-fx-background-insets: 0 0 -1 0, 0, 1, 2;
-fx-background-radius: 5, 5, 4, 3;
...
}
.button:focused {
-fx-color: -fx-focused-base;
-fx-background-color: -fx-focus-color, -fx-outer-border, -fx-inner-border, -fx-body-color;
-fx-background-insets: -1.4, 0, 1, 2;
-fx-background-radius: 6.4, 5, 4, 3;
}
To remove the slight expansion effect, create your own stylesheet. In your stylesheet assign that to your scene and set the background insets and radius for the focused and unfocused button to the same values. Here is a tutorial on JavaFX CSS and the ever useful JavaFX CSS reference guide.
how can I make it work like an menu button (when I press it to remain in focused state untill I press another "menu" button).
I don't quite understand this question - that is the default behavior of a button. Maybe you are mixing focus and arm states and actually want a ToggleButton?
Is there a way to group nodes into the same focus?
Not built into the platform on the moment. You could write your own FocusModel class for a layout pane which remembers the last control in the pane which had focus and reassigns it focus again whenever the pane gets focus back or something like that. It would be custom code though. Concepts you would need to use are the focus property of nodes, the node requestFocus api (sometimes with a delay by executing in Platform.runLater to ensure that you override default focus processing) and the fact that (I think) the default focus order depends on the order of children within a Parent.
Style your own favorite button if you don't like the default one. Otherwise explain the small expand effect with code or image.
Use Menu and MenuItems to make a menu.
Or use Toggle Button to group the buttons and to behave them like a menu.
By saying " to remain in focused state" I assume you meant the "selected/toggled state" instead of focused. Cause the button remains in focused state after clicking on it.
