Azo*_*ger 6 css java netbeans javafx hbox
我有一个 JavaFx 应用程序,为了获得特定的布局,我使用了一些 H- 和 VBox。在一个 HBox 中,我有一个文本字段和一个按钮,我希望它们占据此 HBox 中所有可能的空间。
vboxRight = new VBox(); //This is the right VBox
vboxRight.setSpacing(10);
//This HBox represents the first "Line"
hboxLine = new HBox();
hboxLine.setSpacing(10);
hboxLine.setMinHeight(30);
//Textbox
txtField = new TextField();
txtField.setMinHeight(30);
//Button
btn = new Button("Search");
btn.setMinHeight(30);
btn.setOnAction(this);
hboxLine.getChildren().addAll(txtField, btn);
vboxRight.getChildren().addAll(hboxLine);

有什么办法可以做到这一点吗?也许用CSS?
使用HBox.setHgrow()应该可以解决你的问题。
