```void workbench_panel1(void* parameter)
{
	rt_mq_t mq;
	rtgui_view_t* view;
	rtgui_label_t* label;
	struct rtgui_workbench* workbench;
	rtgui_rect_t rect={0, 0, 320, 240};

mq = rt_mq_create("wmq", 256, 8, RT_IPC_FLAG_FIFO);
	
	rtgui_thread_register(rt_thread_self(), mq);
	
	workbench = rtgui_workbench_create("main", "workbench #1");
	if (workbench == RT_NULL) return;

view = rtgui_view_create("view");
	if (view == RT_NULL) return;	
	RTGUI_WIDGET_BACKGROUND(RTGUI_WIDGET(view)) = blue;

label = rtgui_label_create("RT-Thread");
	rect.x1 = 10; rect.y1 = 10;
	rect.x2 = 210; rect.y2 = 50;

rtgui_widget_set_rect(RTGUI_WIDGET(label), &rect);
	rtgui_container_add_child(RTGUI_CONTAINER(view), RTGUI_WIDGET(label));

rtgui_workbench_add_view(workbench, view);
	
	rtgui_view_show(view, RT_FALSE);

rtgui_workbench_event_loop(workbench);

rtgui_thread_deregister(rt_thread_self());

/* delete message queue */
	rt_mq_delete(mq);
}

/* workbench */
void workbench_init()
{
	rt_thread_t tid;

tid = rt_thread_create("wb", workbench_panel1, RT_NULL, 3072, 20, 5);
	if (tid != RT_NULL) rt_thread_startup(tid);
}
extern rt_err_t rt_hw_lcd_init(void);

这是一个stm32_radio里的example文件夹下的4_gui_single_ panel里的例子，图形驱动已经完成的。主要是程序执行RTGUI_WIDGET_BACKGROUND(RTGUI_WIDGET(view)) = blue;时没对整个屏幕设置成蓝色，就是X方向上留下几列没设置成蓝色。而且我看程序也没对view的大小进行设置，所以不是太明白。求高人指点

我现在又在程序里加了rtgui_widget_get_rect(RTGUI_WIDGET(view), &rect);我看了rect的值是全屏的？奇怪啊  为什么 RTGUI_WIDGET_BACKGROUND(RTGUI_WIDGET(view)) = blue;不全屏啊
