- cursor()
Name(名称):cursor()//鼠标指针样式
Examples(例子):
// Move the mouse left and right across the image
//移动鼠标从左图到右图
// to see the cursor change from a cross to a hand
//看到鼠标光标从一个十字变成一只手
void draw()
{ if (mouseX < 50) {
cursor(CROSS);
} else {
cursor(HAND);
}}
Description(描述):Sets the cursor to a predefined symbol or an image, or makes it visible if already hidden. If you are trying to set an image as the cursor, the recommended size is 16×16 or 32×32 pixels. It is not possible to load an image as the cursor if you are exporting your program for the Web, and not all MODES work with all browsers. The values for parameters x and y must be less than the dimensions of the image.
将光标设置为预定义的符号或图像,或使其可见,如果已经隐藏。如果您试图将图像设置为游标,建议的大小为16×16或32×32像素。如果您正在向Web导出程序,而不是所有的模式都与所有浏览器一起工作,则不可能将图像加载为游标。参数x和y的值必须小于图像的尺寸。
Setting or hiding the cursor does not generally work with “Present” mode (when running full-screen).
设置或隐藏光标通常不会与“当前”模式(在运行全屏时)工作。
With the P2D and P3D renderers, a generic set of cursors are used because the OpenGL renderer doesn’t have access to the default cursor images for each platform (Issue 3791).
使用P2D和P3D渲染器,使用一组通用的游标,因为OpenGL渲染器无法访问每个平台的默认光标图像。
