3, position and click state owing to itself there is mouse in native engine obtain, the position of touching screen mouse and the variable of the state of click adopt the variable of native engine own, so Mouse_getxy, Mouse_getbutton do not need amendment, the function of amendment is needed to only include InitNativeInput, TermNativeInput, Mouse_update, Wait_event.
4, first, amendment InitNativeInput, TermNativeInput function, what in InitNativeInput function, rely on that tslib library file adds touch-screen opens function, adds touch-screen close function at TermNativeInput function.
5, secondly, Mouse_update upgrades position and the state of click of mouse, touching screen mouse state is read out by ts_read function, and assignment is to xpos, ypos, buttons variable respectively, then value transmit is shown to system by Mouse_getxy, Mouse_getbutton by three kinds of variablees.
6, again, in Wait_event, the original mouse of license adds process function, one is if the filec descriptor of touch-screen does not exist, then need to reopen touch-screen, whether two is if there is mouse event, then first detect touch-screen filec descriptor and exist, if existed, whether readablely detect touch-screen filec descriptor, if readable, return a mark IAL_MOUSEEVENT, if the non-rule of filec descriptor directly closes touch-screen.
7, last, after having revised by above step, test on the handset, find after mentioning felt pen, mouse can be run chaotically, the analysis of contrast true form, be cause because touch-screen and mouse disturb mutually, the method for head it off is that one is in Wait_event, if touchscreen events occurs, then the filec descriptor of mouse is allowed to lose efficacy; Two is in Mouse_update, and after having upgraded touchscreen events, if touch-screen is clicked, or the filec descriptor of mouse lost efficacy, and all directly returned.So just can solve felt pen and mention the problem that rear mouse runs chaotically.
