```
#include "demo_view.h"
#include <rtgui/rtgui_system.h>
#include <rtgui/widgets/label.h>
#include <rtgui/widgets/checkbox.h>
#include <rtgui/widgets/window.h>
#include <rtgui/widgets/button.h>

static rtgui_view_t *view1;
static rtgui_checkbox_t* checkbox1;
static rtgui_win_t *win1;
static rtgui_rect_t rect;

/* 改变window中的checkbox位置并重绘window */
static void change_checkbox_position(struct rtgui_widget* widget, struct rtgui_event* event)
{
   rect.y1 +=10;
   rect.y2 +=10;

rtgui_widget_set_rect(RTGUI_WIDGET(checkbox1), &rect);

rtgui_widget_update(RTGUI_WIDGET(win1));	
}

/*创建非模态window*/
void create_new_window(rtgui_widget_t *widget)
{
   	rtgui_toplevel_t *parent;
	rtgui_label_t* label;
	rtgui_rect_t rect_size = {0, 100, 200, 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);

label = rtgui_label_create("这是非模态窗口");
	/* 设置label的位置 */
	rtgui_widget_set_rect(RTGUI_WIDGET(label), &rect_size);
	/* view是一个container控件，调用add_child方法添加这个label控件 */	    	
	rtgui_container_add_child(RTGUI_CONTAINER(win1), RTGUI_WIDGET(label));

rect.x1=0;
	rect.y1=100;
	rect.x2=100;
	rect.y2=120;

/* 创建一个checkbox控件  */
   checkbox1 = rtgui_checkbox_create("test",RT_FALSE);
   /* 设置label的位置 */
   rtgui_widget_set_rect(RTGUI_WIDGET(checkbox1), &rect);
   /* view是一个container控件，调用add_child方法添加这个label控件 */	    	
   rtgui_container_add_child(RTGUI_CONTAINER(win1), RTGUI_WIDGET(checkbox1));

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

rtgui_view_t *wind_test(rtgui_workbench_t* workbench)
{	
	rtgui_button_t *button;

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 + 100;
	widget_rect.y1 += 5;
	widget_rect.y2 = widget_rect.y1 + 20;

button = rtgui_button_create("上移");
	rtgui_widget_set_rect(RTGUI_WIDGET(button), &widget_rect);
	rtgui_container_add_child(RTGUI_CONTAINER(view1), RTGUI_WIDGET(button));
	rtgui_button_set_onbutton(button, change_checkbox_position);

return view1;
}

```

在demo_workbench.c中添加该view
demo_view_dc(workbench);
wind_test(workbench); -----下面的view都屏避掉

在demo_view.c中修改demo_view_next函数
void demo_view_next(struct rtgui_widget* widget, rtgui_event_t *event)
{
	if (demo_view_current + 1< demo_view_number)
	{
		demo_view_current ++;
		rtgui_view_show(demo_view_list[demo_view_current], RT_FALSE);

if ( demo_view_current==1)//这里加上显示非模态窗口的函数
		{
		    create_new_window(RTGUI_WIDGET(demo_view_list[demo_view_current]));
		}
	}
}

这样运行就看到checkbox可以脱离window显示。
