Question

我试图在屏幕中间显示一个对话框。但我无法使用setWidth（）或setHeight（）更改对话框的大小。我有以下代码：

private void showDialog() {
    Window.WindowStyle dialogStyle = new Window.WindowStyle();
    dialogStyle.background = new TextureRegionDrawable(new TextureRegion(dialog_bg));
    dialogStyle.titleFont = gameFont;
    Dialog dialog = new Dialog("Test Dialog", dialogStyle);
    dialog.setWidth(200);   // will be ignored
    dialog.show(stage);
}

有什么想法吗？

只需在调用dialog.show（）之后调用对大小的更改即可。在这种情况下，我将舞台与FitViewport配合使用，因此我按比例缩小了演员以使其适合。调整尺寸时，我必须考虑比例。

public void create(Dialog dialog, float scale){
    dialog.setScale(scale);
    dialog.setMovable(false);

    dialog.text("Are you sure you want to yada yada?");
    dialog.button("Yes", true); //sends "true" as the result
    dialog.button("No", false); //sends "false" as the result
}

public void show(Stage st) {
    dialog.show(st); //pack() is called internally
    dialog.setWidth(worldWidth/scale); //we override changes made by pack()
    dialog.setY(Math.round((st.getHeight() - dialog.getHeight()) / 2)); //we override changes made by pack()
}

无法设置scene2d.ui.Dialog大小
