按鈕盒(Button Boxes)可以很方便地快速佈置一組按鈕。它有水平和垂直兩種樣式。你可以用以下函式創建水平或垂直按鈕盒:
GtkWidget *gtk_hbutton_box_new( void ); GtkWidget *gtk_vbutton_box_new( void ); |
將按鈕添加到按鈕盒中可以用下面這個通常的函式:
gtk_container_add (GTK_CONTAINER (button_box), child_widget); |
下面的範例說明了按鈕盒的不同佈局設置。
#include <gtk/gtk.h> /* 用指定的參數創建一個按鈕盒 */ GtkWidget *create_bbox( gint horizontal, char *title, gint spacing, gint child_w, gint child_h, gint layout ) { GtkWidget *frame; GtkWidget *bbox; GtkWidget *button; frame = gtk_frame_new (title); if (horizontal) bbox = gtk_hbutton_box_new (); else bbox = gtk_vbutton_box_new (); gtk_container_set_border_width (GTK_CONTAINER (bbox), 5); gtk_container_add (GTK_CONTAINER (frame), bbox); /* 設置按鈕盒的外觀 */ gtk_button_box_set_layout (GTK_BUTTON_BOX (bbox), layout); gtk_box_set_spacing (GTK_BOX (bbox), spacing); /*gtk_button_box_set_child_size (GTK_BUTTON_BOX (bbox), child_w, child_h);*/ button = gtk_button_new_from_stock (GTK_STOCK_OK); gtk_container_add (GTK_CONTAINER (bbox), button); button = gtk_button_new_from_stock (GTK_STOCK_CANCEL); gtk_container_add (GTK_CONTAINER (bbox), button); button = gtk_button_new_from_stock (GTK_STOCK_HELP); gtk_container_add (GTK_CONTAINER (bbox), button); return frame; } int main( int argc, char *argv[] ) { static GtkWidget* window = NULL; GtkWidget *main_vbox; GtkWidget *vbox; GtkWidget *hbox; GtkWidget *frame_horz; GtkWidget *frame_vert; /* 初始化 */ gtk_init (&argc, &argv); window = gtk_window_new (GTK_WINDOW_TOPLEVEL); gtk_window_set_title (GTK_WINDOW (window), "Button Boxes"); g_signal_connect (window, "destroy", G_CALLBACK (gtk_main_quit), NULL); gtk_container_set_border_width (GTK_CONTAINER (window), 10); main_vbox = gtk_vbox_new (FALSE, 0); gtk_container_add (GTK_CONTAINER (window), main_vbox); frame_horz = gtk_frame_new ("Horizontal Button Boxes"); gtk_box_pack_start (GTK_BOX (main_vbox), frame_horz, TRUE, TRUE, 10); vbox = gtk_vbox_new (FALSE, 0); gtk_container_set_border_width (GTK_CONTAINER (vbox), 10); gtk_container_add (GTK_CONTAINER (frame_horz), vbox); gtk_box_pack_start (GTK_BOX (vbox), create_bbox (TRUE, "Spread (spacing 40)", 40, 85, 20, GTK_BUTTONBOX_SPREAD), TRUE, TRUE, 0); gtk_box_pack_start (GTK_BOX (vbox), create_bbox (TRUE, "Edge (spacing 30)", 30, 85, 20, GTK_BUTTONBOX_EDGE), TRUE, TRUE, 5); gtk_box_pack_start (GTK_BOX (vbox), create_bbox (TRUE, "Start (spacing 20)", 20, 85, 20, GTK_BUTTONBOX_START), TRUE, TRUE, 5); gtk_box_pack_start (GTK_BOX (vbox), create_bbox (TRUE, "End (spacing 10)", 10, 85, 20, GTK_BUTTONBOX_END), TRUE, TRUE, 5); frame_vert = gtk_frame_new ("Vertical Button Boxes"); gtk_box_pack_start (GTK_BOX (main_vbox), frame_vert, TRUE, TRUE, 10); hbox = gtk_hbox_new (FALSE, 0); gtk_container_set_border_width (GTK_CONTAINER (hbox), 10); gtk_container_add (GTK_CONTAINER (frame_vert), hbox); gtk_box_pack_start (GTK_BOX (hbox), create_bbox (FALSE, "Spread (spacing 5)", 5, 85, 20, GTK_BUTTONBOX_SPREAD), TRUE, TRUE, 0); gtk_box_pack_start (GTK_BOX (hbox), create_bbox (FALSE, "Edge (spacing 30)", 30, 85, 20, GTK_BUTTONBOX_EDGE), TRUE, TRUE, 5); gtk_box_pack_start (GTK_BOX (hbox), create_bbox (FALSE, "Start (spacing 20)", 20, 85, 20, GTK_BUTTONBOX_START), TRUE, TRUE, 5); gtk_box_pack_start (GTK_BOX (hbox), create_bbox (FALSE, "End (spacing 20)", 20, 85, 20, GTK_BUTTONBOX_END), TRUE, TRUE, 5); gtk_widget_show_all (window); /* 進入事件循環 */ gtk_main (); return 0; } |
