Hi，大家好，欢迎来到STM32之littlevGL课堂，我们在上节课中学习了表格控件(lv_table)，本节课带大家学习选项卡控件，大家对选项卡熟悉吗？ 一 有图有真相
没错，这就是一个非常简单的选项卡，就是你在做表格的时候，下面的几个表格切换按钮一样！我们可以通过切换选项从而在一个界面内展示更多的内容。 二 代码分析 void tabview_test(void)
{
/*Create a Tab view object*/
lv_obj_t *tabview;
tabview = lv_tabview_create(lv_scr_act(), NULL);
/*Add 3 tabs (the tabs are page (lv_page) and can be scrolled*/
lv_obj_t *tab1 = lv_tabview_add_tab(tabview, "Tab 1");
lv_obj_t *tab2 = lv_tabview_add_tab(tabview, "Tab 2");
lv_obj_t *tab3 = lv_tabview_add_tab(tabview, "Tab 3");
/*Add content to the tabs*/
lv_obj_t * label = lv_label_create(tab1, NULL);
lv_label_set_text(label, "This the first tab\n\n"
"If the content\n"
"of a tab\n"
"become too long\n"
"the it \n"
"automatically\n"
"become\n"
"scrollable.");
label = lv_label_create(tab2, NULL);
lv_label_set_text(label, "Second tab");
label = lv_label_create(tab3, NULL);
lv_label_set_text(label, "Third tab");
} lv_obj_t *tab1 = lv_tabview_add_tab(tabview, "Tab 1");
lv_obj_t *tab2 = lv_tabview_add_tab(tabview, "Tab 2");
lv_obj_t *tab3 = lv_tabview_add_tab(tabview, "Tab 3"); lv_obj_t * label = lv_label_create(tab1, NULL);
lv_label_set_text(label, "This the first tab\n\n"
"If the content\n"
"of a tab\n"
"become too long\n"
"the it \n"
"automatically\n"
"become\n"
"scrollable.");OK，本节课到就到这里，下节课我们学习窗口控件(lv_win)，我们下节课再见！ |
