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) {}

你好，你的这个问题的解决对我这个新手来说太好了，
但是在这一步之前，我还有一个小问题阻挡着我，希望您赐教一下

就是我现在一个dialog界面中有几个edit 那我点击edit之后如何弹出软键盘dialog呢？
弹出了软键盘之后我才可以按键输入，然后再将输入的内容传给开始那个dialog中的edit

6楼-- · 2019-07-23 00:42

哥们，您的编辑框在选中后，是整个编辑区的内容都被选中了？还是其中一个字符被选中了？现在我初始化编辑框中有初始值，比如001，触摸点击后，只有1变成选中状态！
