如题,简单的说,希望在photon中可以利用自定的X,Y数值来移动mouse位置,并按下click,以用来选取某个位置上的button,谢谢!! 
得到当前位置和移动位置如下：
int button_activate( PtWidget_t *widget, ApInfo_t *apinfo, PtCallbackInfo_t *cbinfo )
{
PhQueryCursor( 0, &buf );
printf( "x=%d y=%d\n", buf.pos.x, buf.pos.y );
int input_group = PhInputGroup( 0 );
PhMoveCursorAbs( input_group, 60, 60 );
/* eliminate 'unreferenced' warnings */
widget = widget, apinfo = apinfo, cbinfo = cbinfo;
return( Pt_CONTINUE );
}
模拟click应该是用PhEventEmit吧，没做过．
谢谢nakeyfish的回覆!!
我之前在help document中有找到PhEmit()及PhEventEmit() (我不是很了解这之前的差异),
并自己在某个button中的callback中写了个function试着去用他,
但当我呼叫完后就会死机,有点类似deadlock的状况, 整个program只剩右上角的X可以按!!
不知道可否帮我看一下那边写错了!!谢谢!!
In button callback:
int
Click_Button2( PtWidget_t *widget, ApInfo_t *apinfo, PtCallbackInfo_t *cbinfo )
{
/* eliminate ‘unreferenced’ warnings */
widget = widget, apinfo = apinfo, cbinfo = cbinfo;
MyPressMouse(20,20);
return( Pt_CONTINUE );
}
In MyPressMouse() function:
void MyPressMouse(int X, int Y)
{
PhRect_t rect;
PhPointerEvent_t EventData;
if( NULL == PhAttach( NULL, NULL ) ) {
fprintf( stderr,
“Couldn’t attach Photon channel.\n”);
exit( EXIT_FAILURE );
}
event.type = Ph_EV_BUT_PRESS;
event.subtype = 0;
event.flags = 0;
event.num_rects = 1;
event.data_len = sizeof(EventData);
event.emitter.rid = Ph_DEV_RID;
rect.ul.x = rect.lr.x = X;
rect.ul.y = rect.lr.y = Y;
EventData.buttons = Ph_BUTTON_SELECT ;
EventData.flags = 0;
PhEventEmit( &event, &rect, &EventData );
}
懒得try，给你个例子吧．如果要按键有动作像手动点一样．我想还需要自己加点代码．(60,60 的根据你button的位置改一下)
例子很简单，写一个新的photon的project, 放两个button.加两个callback.

哇…谢谢nakeyfish给的这个例子, 真的让我又学了不少, 有很多没看过的东西,对我这个新手而言帮助真的太大了, 我得好好研究一下!!
否先请问一下, 例子中是用PtSendEventToWidget来控制event的, 这必需要知道是那个widget才行, 而不能以mouse的(X,Y)来自动判断, 这是否就是PtSendEventToWidget 与PhEmit之间的差异了呢??
