在Javafx中绑定图像 [英] Binding Image in Javafx

问题描述

在我的Javafx应用程序中，我有一个库。我想要做的是，只要图像在文件夹中可用，它就应该在屏幕上显示图像。

In my Javafx application, I have a gallery. What I want to do is that, as soon as an Image is available available in a folder, it should show that Image on the screen.

无论如何都要绑定一个图像在 IamgeView 中。就像任何其他字符串或属性一样？我可以拥有一个名为ImageProperty的东西，它将绑定到Image。因此，如果我更改ImageProperty中的图像，它将更新UI

Is there anyway to bind an Image in an IamgeView. Just like any other String or Property? I can have something called ImageProperty and it will be binded to the Image. So if I change the image in the ImageProperty, it will update the UI

推荐答案

完成。 ImageView有一个可以绑定ObjectProperty的Object属性。

Done. ImageView has an Object Property to which an ObjectProperty can be binded.

ie

private ObjectProperty<javafx.scene.image.Image> imageProperty = new SimpleObjectProperty<>();
@FXML
private ImageView imageDisplay;
Bindings.bindBidirectional(this.imageDisplay.imageProperty(), GlobalModel.getInstance().getProject().getImageProperty());
