使用此index.html:
<!DOCTYPE html>
<html>
<head lang="en">
<meta charset="UTF-8">
<title></title>
<script data-main="main" src="require.js"></script>
</head>
<body>
<p>This is the body</p>
<canvas id="canvas1"></canvas>
</body>
</html>
而这个main.js
console.log("main.js ran");
function render() {
console.log("render ran");
}
window.onload = render;
我希望控制台输出显示:
main.js ran
render ran
"main.js run"按预期显示,但"render ran"未记录.渲染函数永远不会被调用.为什么不？
可以使用DirectWrite将文本渲染到WinForm应用程序中的PictureBox吗？
我正在使用SharpDX并且已经通过DirectWrite示例试图构建我能做到的最简单的工作案例.
我创建了一个Form并且只添加了一个pictureBox.然后是以下代码.表单显示,但PictureBox没有任何可见.
任何指导都将非常感谢.
谢谢!

public …在以下代码中,primaryScene.lookup(第30行)返回null.但是在调试模式(IntelliJ)中,我可以钻取并查看场景图中的节点.
这是一个独立的例子.没有FXML.
应用程序只绘制舞台和场景,然后尝试使用Scene.lookup选择标记为id ="drawPane"的窗格.
