我需要在下拉框元素被选择时重新绘制窗口。
JAVA FX 2.2中如何重新绘制窗口(舞台)?
以下是我的代码:
functionComboBox.valueProperty().addListener(new ChangeListener<String>() {
@Override public void changed(ObservableValue ov, String t, String t1)
{
showFunctionParamters(t1);
}
private void showFunctionParamters(String methodName)
{
gridPaneParameters = new GridPane();
gridPaneParameters.setPadding(new Insets(20, 0, 0, 50));
gridPaneParameters.setHgap(10);
gridPaneParameters.setVgap(4);
int i = 2;
parameterList = methodAttrMap.get(methodName);
Iterator<String> itrParameterList = parameterList.iterator();
while(itrParameterList.hasNext())
{
//TODO allow the user to enter the values for the parameters
Label parameterName = new Label(itrParameterList.next());
TextField parameterTextField = new TextField();
gridPaneParameters.add(parameterName, 1, i);
gridPaneParameters.add(parameterTextField, 2, i);
i++;
}
pane.getChildren().add(gridPaneParameters);
}
});
