JavaFX TableView Rows color - css

I would like to update my TableView rows color depending on the data in the cell, so I used a pseeudoClass to reference the style in Css. the rows are colored as I wanted but, it lost the selection and the mouse hover effect, now I have a colored rows without any indication to the selected row. here is my code:
PseudoClass myPseudoClass = PseudoClass.getPseudoClass("dtta_dep");
PseudoClass myPseudoClass1 = PseudoClass.getPseudoClass("dtta_dest");
fplTableView.setRowFactory(tv -> new TableRow<FlightPlan>() {
#Override
public void updateItem(FlightPlan item, boolean empty) {
super.updateItem(item, empty);
this.setFocused(true);
this.setHover(true);
System.out.println("myPseudoClass = "+myPseudoClass.getPseudoClassName());
pseudoClassStateChanged(myPseudoClass, (! empty) && item.Dep_aerodomProperty().get().equalsIgnoreCase("DTTA"));
pseudoClassStateChanged(myPseudoClass1, (! empty) && item.Dest_aerodomProperty().get().equalsIgnoreCase("DTTA"));
}
});
getData();
for (int i = 0; i < listF.size(); i++) {
System.out.println(listF.get(i).Dep_aerodomProperty().get());
}
selectWithService();
});
the css file :
.table-row-cell {
-fx-background-color: linear-gradient(white 0%, white 90%, #e0e0e0 90%);
}
.table-row-cell:selected {
-fx-background-color: linear-gradient(#95caff 0%, #77acff 90%, #e0e0e0 90%);
}
.table-row-cell:dtta_dep .table-cell {
-fx-text-fill: red;
-fx-background-color:beige;
}
.table-row-cell:dtta_dest .table-cell {
-fx-text-fill: blue;
-fx-background-color:greenyellow;
}

Use -fx-background instead of -fx-background-color on the table-row-cell to set the non-selected background. You can use -fx-selection-bar to set the selected color. The text fill is defined in a table cell with the -fx-text-background-color color, (i.e. the text fill for text over a -fx-background), so you can override those for the text fill in the cells.
.table-row-cell {
-fx-background: linear-gradient(white 0%, white 90%, #e0e0e0 90%);
-fx-selection-bar: linear-gradient(#95caff 0%, #77acff 90%, #e0e0e0 90%);
}
.table-row-cell:dtta_dep {
-fx-text-background-color: red;
-fx-background: beige;
}
.table-row-cell:dtta_dest {
-fx-text-background-color: blue;
-fx-background:greenyellow;
}

JavaFX tableview with CSS scrolling issue

I am currently facing a problem with javafx table. I have a tableview that shows a list of subjects. The background color of each row depends if a subject is able to be enrolled or not. Subjects with green background can be enrolled and subjects with pink background cannot be enrolled. The problem occurs when scrolling the table.
TableView before scrolling
TableView after scrolling down and up
After scrolling, the background color of rows have changed and the subjects with green background might become pink and vice versa. This works perfectly without adding a css to the table.
Code I used to set the background color of rows
tblAvailableSubjects.setRowFactory((TableView<Subject> param) -> {
TableRow<Subject> row = new TableRow<>();
row.emptyProperty().addListener((obs, wasEmpty, isEmpty) -> {
if(isEmpty) {
row.setContextMenu(null);
row.setStyle("-fx-border-color: transparent");
} else {
Subject subject = row.getItem();
if(subject.getSubjectEvaluation().equals(SubjectEvaluation.COMPLETED)) {
row.setStyle("-fx-background: #B2EBF2");
} else if(subject.getSubjectEvaluation().equals(SubjectEvaluation.FAILED)) {
row.setStyle("-fx-background: #FF0000");
row.setContextMenu(tblAvailableContext);
} else if(subject.getSubjectEvaluation().equals(SubjectEvaluation.OKAY)) {
row.setStyle("-fx-background: #8BC34A");
row.setContextMenu(tblAvailableContext);
} else if(subject.getSubjectEvaluation().equals(SubjectEvaluation.ENROLLWITHCOREQ)) {
row.setStyle("-fx-background: #FFEB3B");
row.setContextMenu(tblAvailableContext);
} else if(subject.getSubjectEvaluation().equals(SubjectEvaluation.CANTENROLL)) {
row.setStyle("-fx-background: #FFCDD2");
}
}
});
return row;
});
CSS for table
.table-view {
/* Constants used throughout the tableview. */
-fx-table-header-border-color: transparent;
-fx-table-cell-border-color: -fx-box-border;
/* Horizontal Lines*/
-fx-background-color: transparent;
}
.table-view .filler, .table-view .column-header
{
-fx-size: 40;
-fx-border-style: null;
-fx-border-color: rgb(200.0, 200.0, 200.0);
-fx-border-width: 0 0 1 0;
-fx-background-color: transparent;
}
.table-view .show-hide-columns-button
{
-fx-background-color: transparent;
}
.table-view .column-header .label,
.table-view .column-drag-header .label
{
-fx-alignment: CENTER_LEFT;
}
.table-view .column-header-background
{
-fx-background-color: transparent;
}
.table-row-cell {
-fx-cell-size: 30px;
}
.table-cell {
-fx-border-color: transparent;
-fx-border-width: 1;
}
EDIT: The subject's SubjectEvaluation value doesn't change, it seems that it switches the context menu and background color between rows when scrolling.
I hope someone could help me with this. Thanks.

JavaFX how to hide empty column cell in tableView

I am using a tableView with UNCONSTRAINED_RESIZE_POLICY.
And I want set all empty column cell to white background.
This is the current view.
I am trying to search the empty node, but I can't find it even if I search all the nodes contained in tableView by following code (test function):
private void test() {
ArrayList<Node> nodes = getAllNodes(tableView);
nodes.forEach(node -> {
if(node instanceof TableCell) {
if(((TableCell) node).getText() == null || ((TableCell) node).getText().isEmpty()) {
System.out.println(true);
}
}
});
}
public static ArrayList<Node> getAllNodes(Parent root) {
ArrayList<Node> nodes = new ArrayList<Node>();
addAllDescendents(root, nodes);
return nodes;
}
private static void addAllDescendents(Parent parent, ArrayList<Node> nodes) {
for (Node node : parent.getChildrenUnmodifiable()) {
nodes.add(node);
if (node instanceof Parent)
addAllDescendents((Parent)node, nodes);
}
}
Use a CSS stylesheet to apply the styles to remove the background from TableRowCells and instead add the background to the TableCells:
/* overwrite default row style */
.table-row-cell {
-fx-background-color: transparent;
-fx-background-insets: 0;
}
/* apply row style to cells instead */
.table-row-cell .table-cell {
-fx-background-color: -fx-table-cell-border-color, -fx-background;
-fx-background-insets: 0, 0 0 1 0;
}
.table-row-cell:odd {
-fx-background: -fx-control-inner-background-alt;
}
/* fix markup for selected cells/cells in a selected row */
.table-row-cell:filled > .table-cell:selected,
.table-row-cell:filled:selected > .table-cell {
-fx-background: -fx-selection-bar-non-focused;
-fx-table-cell-border-color: derive(-fx-background, 20%);
}
.table-view:focused > .virtual-flow > .clipped-container > .sheet > .table-row-cell:filled:selected .table-cell,
.table-view:focused > .virtual-flow > .clipped-container > .sheet > .table-row-cell .table-cell:selected {
-fx-background: -fx-selection-bar;
}
scene.getStylesheets().add(getClass().getResource("style.css").toExternalForm());
Note: There are no TableCells outside of existing columns. The background is applied to the TableRowCells.
Also retrieving the cells from a virtualizing control is a bad idea:
The cells are created during the first layout pass. They may not be present at the time you run your code.
Interacting with the control (e.g. by resizing it, scrolling it, ect.) may result in creation of additional cells. Any modifications you've done to the cells you found before by traversing the scene are not applied to those new nodes automatically.
The easiest way is:
.table-row-cell:empty {
-fx-background-color: transparent;
}

Make a dark mode with JavaFx

I was wondering if there is an easy way to make a dark mode using JavaFx and CSS. I have a MenuBar with a CheckMenuItem called 'Dark mode' and when I click it I want the scene to become dark and the text to become white.
Here's mine.
(Update) The previous one was too opaque.
.root {
-fx-accent: #1e74c6;
-fx-focus-color: -fx-accent;
-fx-base: #373e43;
-fx-control-inner-background: derive(-fx-base, 35%);
-fx-control-inner-background-alt: -fx-control-inner-background ;
}
.label{
-fx-text-fill: lightgray;
}
.text-field {
-fx-prompt-text-fill: gray;
}
.titulo{
-fx-font-weight: bold;
-fx-font-size: 18px;
}
.button{
-fx-focus-traversable: false;
}
.button:hover{
-fx-text-fill: white;
}
.separator *.line {
-fx-background-color: #3C3C3C;
-fx-border-style: solid;
-fx-border-width: 1px;
}
.scroll-bar{
-fx-background-color: derive(-fx-base,45%)
}
.button:default {
-fx-base: -fx-accent ;
}
.table-view{
/*-fx-background-color: derive(-fx-base, 10%);*/
-fx-selection-bar-non-focused: derive(-fx-base, 50%);
}
.table-view .column-header .label{
-fx-alignment: CENTER_LEFT;
-fx-font-weight: none;
}
.list-cell:even,
.list-cell:odd,
.table-row-cell:even,
.table-row-cell:odd{
-fx-control-inner-background: derive(-fx-base, 15%);
}
.list-cell:empty,
.table-row-cell:empty {
-fx-background-color: transparent;
}
.list-cell,
.table-row-cell{
-fx-border-color: transparent;
-fx-table-cell-border-color:transparent;
}
It's been a while since I played with "theming" a JavaFX application, but from a while ago I have a CSS file:
.root {
-fx-base: #3f474f;
-fx-accent: #e7eff7 ;
-fx-default-button: #7f878f ;
-fx-focus-color: #efefef;
-fx-faint-focus-color: #efefef22;
-fx-focused-text-base-color : ladder(
-fx-selection-bar,
-fx-light-text-color 45%,
-fx-dark-text-color 46%,
-fx-dark-text-color 59%,
-fx-mid-text-color 60%
);
-fx-focused-mark-color : -fx-focused-text-base-color ;
}
.text-input:focused {
-fx-highlight-text-fill: ladder(
-fx-highlight-fill,
-fx-light-text-color 45%,
-fx-dark-text-color 46%,
-fx-dark-text-color 59%,
-fx-mid-text-color 60%
);
}
If you put this in a file, say dark-theme.css, you can do
checkMenuItem.selectedProperty().addListener((obs, wasSelected, isSelected) -> {
if (isSelected) {
scene.getStyleSheets().add("dark-theme.css");
} else {
scene.getStyleSheets().remove("dark-theme.css");
}
});
the property base can be applied to every JavaFX type, This enables a color theme to be specified using a single base color for a JavaFx Node or Layout..., and to have variant colors (for its children) computed based on that base color!
in this case, you are trying to set the theme for the whole scene so you should apply the base color to the highest Component in the hierarchy which you can get by getting the root Node of your scene!
checkMenuItem.selectedProperty().addListener((obs, wasSelected, isSelected) -> {
if (isSelected) {
scene.getRoot().setStyle("-fx-base:black");
} else {
scene.getRoot().setStyle("");
}
});
I'm new to javafx and all, but I'm pretty sure creating 2 stylesheets and switching between them would suffice.
Again if what I said was wrong, sorry, I'm new to javafx

JAVAFX - Transparent bar on button using CSS

I want my button to have a transparent black bar on the bottom with a opacity of 75%. The button name should appear on top of the black bar. I have drawn a draft below.
So far I have tried with no success:
.button{
-fx-background-color: #5a9bdc;
-fx-font-size: 16;
-fx-effect: dropshadow( three-pass-box , rgba(0,0,0,0.4) , 5, 0.0 , 0 , 1 );
-fx-text-fill: #ffffff;
}
.button:hover {
-fx-background-color: #97c0dc;
}
UPDATE:
So this is how my css looks:
.button-stats.parent{
-fx-background-color: #5a9bdc;
-fx-font-size: 16;
-fx-effect: dropshadow( three-pass-box , rgba(0,0,0,0.4) , 5, 0.0 , 0 , 1 );
-fx-text-fill: #ffffff;
}
.button-stats:hover {
-fx-background-color: #97c0dc;
}
.button-stats.element{
padding: 20px;
color: rgba(255,255,255,.4);
position: absolute;
bottom: 0;
left: 0;
right: 0;
}
Here is a sample, it isn't going to be exactly what you want, but may help you in getting to where you want. It is based upon button styles found in modena.css in the jfxrt.jar that ships with Java 8.
Images are shown for unhovered and hovered and armed states (armed is when the button is pressed and the shadow is removed).
I did not provide info here for a focused state, so you will need to develop that yourself if you want it.
super-button.css
.button {
-custom-solid-button-color: lightgreen;
-custom-translucent-button-color: rgba(00, 80, 00, 0.75);
-custom-button-color:
linear-gradient(to bottom,
-custom-solid-button-color 0%,
-custom-solid-button-color 64%,
-custom-translucent-button-color 65%);
-fx-background-color: -custom-button-color;
-fx-background-insets: 0;
-fx-background-radius: 0;
-fx-text-fill: whitesmoke;
-fx-padding: 3.333333em 0.666667em 0.333333em 0.666667em;
-fx-font-size: 30px;
-fx-effect: dropshadow(gaussian, black, 10, 0, 3, 3);
}
.button:hover {
-custom-solid-button-color: derive(lightgreen, 20%);
-fx-effect: dropshadow(gaussian, goldenrod, 10, 0, 3, 3);
}
.button:armed {
-custom-solid-button-color: derive(lightgreen, -10%);
-fx-effect: null;
-fx-background-insets: 2 2 0 0;
}

Getting the translucent area at the base is slightly tricky, especially because you are applying a drop shadow effect. What happens with a drop shadow effect is that the drop shadow is visible through the translucent area. Normally, when you have an opaque foreground, you can see the shadow through the foreground, but when you have a translucent foreground, the shadow mars the translucent effect a bit. To understand what I mean, review the above images and note the difference between the translucent area in the images with and without a drop shadow involved.
So you might want to rethink the design to not use the drop shadow. There are ways around this using clips, but it gets a bit more complicated and you cannot achieve it using just CSS (you will also need to write some custom skin code in Java, which I won't demonstrate here).
Try
.button {
-fx-opacity: 0.7;
}

JavaFX : Style combobox popup list text color and selected item color?

I have problem with styling ComboBox in css. I don't know how to change font color of selected item fx (2 people from black color to red), and how to set color effect when you point mouse on the current choice.
css code:
.combo-box
{
-fx-background-image:url("people_button.jpg");
-fx-text-fill: red;
-fx-min-width: 128;
-fx-min-height: 48;
}
.combo-box-popup .list-view
{
-fx-background-color: -fx-box-border, -fx-control-inner-background;
-fx-background-insets: 0, 1;
-fx-effect: dropshadow( three-pass-box , rgba(0,0,0,0.6) , 8, 0.0 , 0 , 0 );
}
.combo-box-popup .list-view .list-cell
{
-fx-background-color: #ececec;
-fx-text-fill: #9a9a9a;
-fx-font-family: Oxygen Light;
}
and java code:
ComboBox<String> combo = new ComboBox();
combo.setVisibleRowCount(5);
combo.setItems(observableList);
combo.setValue("1 person");
Just add the pseudo-class hover to your style sheet :
.combo-box-popup .list-view .list-cell:hover {
-fx-text-fill: red;
}
For adding a color to the selected item, use the pseudo-class selected :
.combo-box .cell:selected {
-fx-text-fill: red;
}
