上一篇文章谈到了多窗体，还是依照约定看一下效果是什么样的。

假设大家细心一点。就会发现窗体中的label显示为window01，这事实上是由于我们已经添加了一个窗体，有兴趣的朋友能够尝试编译一下。如题所看到的，今天讨论的是combox。所谓的combox，事实上就是从给出的若干个选择挑选出一个就可以。

闲话少说，还是看代码。

#include "ftk.h"#define IDC_TEST_BUTTON 1000static Ret button_quit_clicked(void* ctx, void* obj){	ftk_quit();	return RET_OK;}int FTK_MAIN(int argc, char* argv[]){	int width = 0;	int height = 0;	FtkWidget* win = NULL;	FtkWidget* button = NULL;	FtkWidget* combo_box = NULL;	ftk_init(argc, argv);		win = ftk_app_window_create();	width = ftk_widget_width(win);	height = ftk_widget_height(win);		width = width/2 - 10;	combo_box = ftk_combo_box_create(win, 0, height/4, width, 50);	ftk_combo_box_set_text(combo_box, "1 second");	ftk_combo_box_append(combo_box, NULL, "1 second");	ftk_combo_box_append(combo_box, NULL, "2 seconds");	ftk_combo_box_append(combo_box, NULL, "3 seconds");	combo_box = ftk_combo_box_create(win, width + 10, height/4, width, 50);	ftk_combo_box_set_text(combo_box, "1 second");	ftk_combo_box_append(combo_box, NULL, "1 second");	ftk_combo_box_append(combo_box, NULL, "2 seconds");	ftk_combo_box_append(combo_box, NULL, "3 seconds");	ftk_combo_box_append(combo_box, NULL, "4 seconds");	ftk_combo_box_append(combo_box, NULL, "5 seconds");	ftk_combo_box_append(combo_box, NULL, "6 seconds");	ftk_combo_box_append(combo_box, NULL, "7 seconds");	ftk_combo_box_append(combo_box, NULL, "8 seconds");	ftk_combo_box_append(combo_box, NULL, "9 seconds");	ftk_combo_box_append(combo_box, NULL, "0 seconds");	ftk_combo_box_append(combo_box, NULL, "0 seconds");	button = ftk_button_create(win, width/2, height/2, width, 60);	ftk_widget_set_text(button, "quit");	ftk_button_set_clicked_listener(button, button_quit_clicked, win);	ftk_window_set_focus(win, button);	combo_box = ftk_combo_box_create(win, 0, 3*height/4+5, width, 50);	ftk_combo_box_set_text(combo_box, "1 second");	ftk_combo_box_append(combo_box, NULL, "1 second");	ftk_combo_box_append(combo_box, NULL, "2 seconds");	ftk_combo_box_append(combo_box, NULL, "3 seconds");	combo_box = ftk_combo_box_create(win, width + 10, 3*height/4+5, width, 50);	ftk_combo_box_set_text(combo_box, "1 second");	ftk_combo_box_append(combo_box, NULL, "1 second");	ftk_combo_box_append(combo_box, NULL, "2 seconds");	ftk_combo_box_append(combo_box, NULL, "3 seconds");	ftk_combo_box_append(combo_box, NULL, "4 seconds");	ftk_combo_box_append(combo_box, NULL, "5 seconds");	ftk_combo_box_append(combo_box, NULL, "6 seconds");	ftk_combo_box_append(combo_box, NULL, "7 seconds");	ftk_combo_box_append(combo_box, NULL, "8 seconds");	ftk_combo_box_append(combo_box, NULL, "9 seconds");	ftk_combo_box_append(combo_box, NULL, "0 seconds");	ftk_combo_box_append(combo_box, NULL, "0 seconds");		ftk_widget_set_text(win, "ComboBox Demo");	ftk_widget_show_all(win, 1);	ftk_widget_set_attr(win, FTK_ATTR_QUIT_WHEN_CLOSE);	ftk_run();	return 0;}

相信大家看了上面的代码就不操心了。假设想创建combox，直接调用函数ftk_combo_box_create就可以；假设须要加入条目，调用函数ftk_combo_box_append就可以；假设须要设定默认选项，调用ftk_combo_box_set_text函数就可以。就是这么简单。

下次看效果图。
