问题描述:窗口和view都有textbox时,都可以获得焦点. 我觉得应当是界面上应当只有一个控件获得焦点.
```
#include "demo_view.h"
#include <rtgui/rtgui_system.h>
#include <rtgui/widgets/label.h>
#include <rtgui/widgets/checkbox.h>

static rtgui_win_t *win1;

/*创建非模态window*/
void create_new_window1(rtgui_widget_t *widget)
{
   rtgui_textbox_t* text;
    rtgui_toplevel_t *parent;
   
   rtgui_rect_t rect_label,rect_size = {0, 0, 240, 120};

parent = RTGUI_TOPLEVEL(rtgui_widget_get_toplevel(widget));

/* 创建一个窗口，风格为无标题及无边框 */
   win1 = rtgui_win_create(parent,
      "Table", &rect_size, RTGUI_WIN_STYLE_NO_TITLE);

rtgui_rect_moveto(&rect_size, 0, 45);

rtgui_win_set_rect(win1,&rect_size);

rect_label.x1=5;
   rect_label.y1=rect_size.y1;
   rect_label.y2=rect_label.y1+20;
      
   text = rtgui_textbox_create("",RTGUI_TEXTBOX_SINGLE);	 
   rtgui_widget_set_rect(RTGUI_WIDGET(text), &rect_label);	
   rtgui_container_add_child(RTGUI_CONTAINER(win1), RTGUI_WIDGET(text));

/* 非模态显示窗口 */
   rtgui_win_show(win1, RT_FALSE);   
}

rtgui_view_t *test_focus(rtgui_workbench_t* workbench)
{ 
   rtgui_view_t *view1;
   rtgui_button_t *button; 
   rtgui_textbox_t* text;

rtgui_rect_t widget_rect;

view1 = demo_view(workbench, "test"); 
   
   demo_view_get_rect(view1, &widget_rect);
   widget_rect.x1 = 5;
   widget_rect.x2 = widget_rect.x1 + 50;
   widget_rect.y1 = 170;
   widget_rect.y2 = widget_rect.y1 + 20;
   
   button = rtgui_button_create("窗口");
   rtgui_widget_set_rect(RTGUI_WIDGET(button), &widget_rect);
   rtgui_container_add_child(RTGUI_CONTAINER(view1), RTGUI_WIDGET(button));
   rtgui_button_set_onbutton(button, create_new_window1);

widget_rect.x1 = widget_rect.x2;
   widget_rect.x2 += 50;
   
   text = rtgui_textbox_create("",RTGUI_TEXTBOX_SINGLE);	 
   rtgui_widget_set_rect(RTGUI_WIDGET(text), &widget_rect);	
   rtgui_container_add_child(RTGUI_CONTAINER(view1), RTGUI_WIDGET(text));

return view1;
}
```测试代码如下:
