I have a concern with a combobox that I created in JavaFx, this is to be managed from a touch screen for a touch application, in this combobox the scroll bar is not always visible and it is impossible to download or move the information in the and tried from the css and I have not succeeded. Is it possible to do it from the code or what do you recommend I do with it? This is the code I used to try to make it visible all the time the ComboBox is deployed.
.combo-box-popup .list-view .scroll-bar:vertical .thumb
{
-fx-max-width: 12px;
-fx-background-color: black;
-fx-background-insets: 2, 0, 0;
-fx-background-size: 20px,40px;
-fx-background-position: center 5% , center 95%;
}
.combo-box-popup .list-view .scroll-bar .thumb:hover,
.combo-box-popup .list-view .scroll-bar .thumb:pressed{
-fx-background-color: derive(black,90%);
-fx-min-width: 12px;
}
.combo-box-popup .list-view .scroll-bar:horizontal .thumb,
.combo-box-popup .list-view .scroll-bar:vertical .thumb {
-fx-background-color:derive(black,90%);
-fx-min-width: 12px;
-fx-background-insets: 0, 0, 0;
-fx-background-radius: 0em;
visibility: visible;
}
