[英]JavaFx, FXML, how to auto resize content: Button, StackPane, Field, Scrollpane according to their parents
我正在嘗試使用Fxml(SceneBuilder)設計Java應用程序,我現在面臨的問題是,我無法自動調整內容的大小,根據GridPane(1,2)行的ScrollPane,根據GridPane行的StackPane 2以及Button和Textfield(根據窗格)。 是否有可以幫助我的財產或任何替代解決方案?

我不確定您是否有意將內容包裝到多個窗格中,但這是不必要的。 如果您調用AnchorPane.setTopAnchor(Node)
, AnchorPane.setRightAnchor(Node)
, AnchorPane.setBottomAnchor(Node)
或AnchorPane.setLeftAnchor(Node)
,則窗格不會自動調整其內容的大小,並且AnchorPanes僅會調整內容的大小。
首先,GridPane。 您可以分別設置RowConstraints和ColumnConstraints的VGrow和HGrow屬性,以根據GridPane的大小調整內容的大小。 設置RowConstraints和ColumnConstraints的percentHeight和percentWidth還將有助於使行和列保持其首選比例。
在ScrollPane上,設置fitToWidth和fitToHeight屬性,以保持其子項的大小與ScrollPane的大小匹配。
對於輸入區域,HBox比Pane更適合,因此您可以更輕松地調整文本字段和按鈕的大小。 將每個Label的圖形設置為其對應的文本字段也將有助於將兩者保持在一起。
這是您整理過的fxml代碼,可為您提供更好的主意。
