Class MFXComboBoxSkin<T>

java.lang.Object

javafx.scene.control.SkinBase<MFXTextField>

io.github.palexdev.materialfx.skins.MFXTextFieldSkin

io.github.palexdev.materialfx.skins.MFXComboBoxSkin<T>

All Implemented Interfaces:

Skin<MFXTextField>

Direct Known Subclasses:

MFXFilterComboBoxSkin

public class MFXComboBoxSkin<T>
extends MFXTextFieldSkin

Skin associated with every MFXComboBox by default.

Extends MFXTextFieldSkin since most features are inherited from MFXTextField and adds the necessary properties/behaviors to add the popup listview.

The listview used in the popup is not really a listview, but I decided to directly use a SimpleVirtualFlow to make things easier, so that I don't have to worry about synchronization between the combobox' selection model and the listview' selection model
