【问题描述】:
我有下面的代码允许有两个窗口,在主窗口中按下'k'键时,必须调用Graph的函数disegna()并添加文本。
但是好像不能正常工作,没有出现draw update。
你能帮帮我吗?
int N = 500;
boolean flag = false;
Grafico graph = new Grafico(N, N);
void settings() {
size(N, N);
}
void setup() {
surface.setTitle("Grafico1");
surface.setLocation(0, 0);
String[] args = {
"--location=" + (N*2) + ",0",
"Grafico2"
};
PApplet.runSketch(args, graph);
grafico();
}
void grafico() {
background(0);
text("Main", 10, 20);
}
void keyPressed() {
switch (key) {
case 'k':
graph.disegna();
break;
}
}
void draw() {
if (!flag) {
frame.setLocation(0, 0);
flag = true;
}
}
public class Grafico extends PApplet {
private final int w, h;
public Grafico(int w, int h) {
this.w = w;
this.h = h;
}
void settings () {
size(w, h);
}
void setup() {
ini();
}
void ini() {
background(0);
text("Second", 10, 20);
}
void disegna() {
text("Hello!", 10, 50);
println("Hello!");
}
void draw() {
}
}
