问题描述
大家好，我的 QML 代码有问题.我犯了一个错误，我给元素设置了一定的大小，现在我在将应用程序放在其他设备上时遇到了问题.我会将我的代码粘贴到我有宽度和高度的位置，以便您可以更改它以向我展示如何使用动态调整大小.
Hi all I have problem with my QML code. I made mistake and I went to put certain size to elements and now I have problem when putting app on other devices. I will paste you my code where I have width and height so you can change it to show me how to work with dynamic resizeing.
我需要说明的是，我正在使用以下代码从 qt 调用 qml 文件:
I need to say that I am calling qml file from qt with this code:
QDeclarativeView *view= new QDeclarativeView;
ui->setupUi(this);
setCentralWidget(view);
QDeclarativeContext *ctxt = view->rootContext();
ctxt->setContextProperty("funkcije",this);
ctxt->setContextProperty("myModel", QVariant::fromValue(MainWindow::dataList));
view->setSource(QUrl("qrc:/gui.qml"));
view->setResizeMode(QDeclarativeView::SizeRootObjectToView);
showFullScreen();
这是我的 QML 代码:
And here goes my QML code:

我已经把所有的代码都加上了宽度和高度，所以你可以看到我做错了什么.如果有人能告诉我如何让它动态填充.
I have put all the code with width and height so you can see what I have done wrong. And please if someone can say me how to make it dynamically fill.
推荐答案
不幸的是，要做到完美是很棘手的，因为随着屏幕尺寸的缩小，您可能实际上希望按钮更大，并将内容从屏幕上拖放到确保用户可以访问和阅读一切正常.
It's unfortunately tricky to get perfect, as it's likely that as the screen size shrinks you might actually want the buttons to be bigger and to drop content from the screen to ensure the user can access and read everything ok.
但一般的做法其实是在C++端设置一个比例因子:
But the general approach is actually to set a scale factor in the C++ side:
ctxt->setContextProperty("scale", /* put calculated scale factor here */);
然后在 QML 方面，使用每个人来缩放所有对象:
And then on the QML side, use that everyone to scale all the objects:
Rectangle {
id:window
width: 602 * scale
height: 1000 * scale
这样您就可以调整比例变量以更改所有内容的大小.尽管如此，许多人最终会根据平台大小获得不同的 QML 文件.
That way you can adjust the scale variable to change everything's size. Having said that, many people end up with different QML files depending on the platform size though.
