我正在为Node.js创建一组GLFW 3.1.2绑定。我遇到了一个特定API的问题,特别是glfwSetMonitorCallback
API。GLFW监视器回调未触发
问题是,当我断开连接或将监视器连接到我的系统时,它没有被触发。
以下是我的回调处理程序:
void monitor::onGLFWMonitor (GLFWmonitor* monitor, int action) {
Isolate* isolate = Isolate::GetCurrent();
HandleScope scope(isolate);
auto it = monitor::monitorObjects.find(monitor);
Local<Object> jsMonitor;
if (it == monitor::monitorObjects.end()) {
// New monitor, add it
jsMonitor = monitor::monitorObjectTemplate.Get(isolate)->NewInstance();
jsMonitor->SetAlignedPointerInInternalField(0, monitor);
jsMonitor->SetInternalField(1, String::NewFromUtf8(isolate, "GLFWmonitor"));
CopyablePersistent<Object> perst(isolate, jsMonitor);
MonitorIndexedPair<Object> pr(monitor, perst);
it = monitor::monitorObjects.insert(pr).first;
} else {
jsMonitor = it->second.Get(isolate);
}
if (action == GLFW_DISCONNECTED) {
// Monitor removed, clean up!
jsMonitor->SetAlignedPointerInInternalField(0, NULL);
monitor::monitorObjects.erase(it);
// TODO Cleanup video modes once implemented
}
if (monitor::monitorCallback.IsEmpty()) {
// No callback, do nothing
return;
}
Local<Function> callback = monitor::monitorCallback.Get(isolate);
const unsigned int argc = 2;
Local<Value> argv[argc] = {
jsMonitor,
Number::New(isolate, action)
};
callback->Call(isolate->GetCurrentContext()->Global(), argc, argv);
}
它被设置为任何呼叫的部分glfwInit
像这样:
void core::init (const FunctionCallbackInfo<Value>& args) {
Isolate* isolate = Isolate::GetCurrent();
HandleScope scope(isolate);
bool result = glfwInit();
if (result == GL_TRUE) {
// Setup callbacks
glfwSetMonitorCallback(monitor::onGLFWMonitor);
}
args.GetReturnValue().Set(Boolean::New(isolate, result == GL_TRUE));
}
我增加了一些printf
语句转换为回调函数,并没有他们是有史以来生产的。此外,如果我拨打glfwGetMonitors
,它总是返回错误的显示器数量。 EG:我有两台显示器,断开连接,glfwGetMonitors
仍然返回两台显示器。
我在运行Windows 7,Windows 8/8.1和Windows 10的多台计算机上看到此问题。任何建议,将不胜感激。
