ucGUI 多编辑框EDIT与软键盘关于焦点问题？终于解决，原来这么简单

主要遇见的难题：
1、因为软键盘和Edit编辑框是处于同一LCD中，通过鼠标或者触摸都会是焦点改变。
2、在键盘点击事件中，无法知道之前是选择的是那个Edit编辑器。
3、在选择Edit编辑器之后，点击键盘后怎么把焦点从新锁定在之前选择的Edit上（在刚刚输入的字符后面）。

现在的源码如下：
[code=c]
#include <stddef.h> #include "GUI.h" #include "DIALOG.h"
#include "WM.h" #include "BUTTON.h" #include "CHECKBOX.h" #include "DROPDOWN.h" #include "EDIT.h" #include "FRAMEWIN.h" #include "LISTBOX.h" #include "MULTIEDIT.h" #include "RADIO.h" #include "SLIDER.h" #include "TEXT.h" #include "PROGBAR.h" #include "SCROLLBAR.h" #include "LISTVIEW.h"

EDIT_Handle Cd_edit_handle;      // 全局edit句柄 // 事件 void OnButton0Clicked(WM_MESSAGE * pMsg) { // WM_HWIN hWin = pMsg->hWin; /************************* 此处无法锁定是之前鼠标点击的edit（编辑器），？ *************************/
   WM_SetFocus(Cd_edit_handle); // 锁定光标在之前选择的edit中 EDIT_AddKey(Cd_edit_handle, '0'); // 向之前edit中输入数据 } void OnButton1Clicked(WM_MESSAGE * pMsg) {} void OnButton2Clicked(WM_MESSAGE * pMsg) {} void OnButton3Clicked(WM_MESSAGE * pMsg) {} void OnButton4Clicked(WM_MESSAGE * pMsg) {} void OnButton5Clicked(WM_MESSAGE * pMsg) {} void OnButton6Clicked(WM_MESSAGE * pMsg) {} void OnButton7Clicked(WM_MESSAGE * pMsg) {} void OnButton8Clicked(WM_MESSAGE * pMsg) {} void OnButton9Clicked(WM_MESSAGE * pMsg) {} void OnButton10Clicked(WM_MESSAGE * pMsg) {} void OnButton11Clicked(WM_MESSAGE * pMsg) {
WM_SetFocus(Cd_edit_handle);    // 锁定光标在之前选择的edit中 GUI_SendKeyMsg(GUI_KEY_BACKSPACE, 1); // 删除edit的数据（相当于键盘上的删除键功能） } void OnButton12Clicked(WM_MESSAGE * pMsg) {}

我这就是在那买的板子   可我没找到ucGUI方面的详细资料。
刚学  也不是很深   昨天太急帖子发错了  名字应该是“多编辑框EDIT与软键盘关于焦点定位问题？？？”。
我从发下
谢谢

我通常初始化的时候这么做的,没搞的这么麻烦:

把按键设置成了不可聚焦BUTTON_SetFocussable(hItem, 0);/* Set all buttons non focussable */
编辑框设置成了可聚焦WM_SetFocus(WM_GetDialogItem(hWin,GUI_ID_EDIT0));

谢谢楼上 GUI手册中我也没找到这个函数刚学也不是很清楚你讲的挺好的谢谢我自己的那个也是查看别人的代码的可以这么用的看的不多
我有个疑点在下面：在事件处理函数中是不是还是要向下面这样处理呢？用WM_HasFocus（hwin）函数进行轮询操作呢？有没有更好的办法？
// 事件 void OnButton0Clicked(WM_MESSAGE * pMsg) { WM_HWIN hWin = pMsg->hWin; if(WM_HasFocus(WM_GetDialogItem(hWin,GUI_ID_EDIT1))) { WM_SetFocus(WM_GetDialogItem(hWin,GUI_ID_EDIT1)); EDIT_AddKey( WM_GetDialogItem(hWin,GUI_ID_EDIT1), '0'); // 向之前edit中输入数据 }else if(WM_HasFocus(WM_GetDialogItem(hWin,GUI_ID_EDIT0))) { WM_SetFocus(WM_GetDialogItem(hWin,GUI_ID_EDIT1)); EDIT_AddKey( WM_GetDialogItem(hWin,GUI_ID_EDIT0), '0'); // 向之前edit中输入数据 } }
