Fixed Container故名之意就是固定容器，它容許把控件放到一個固定容器中，并能隨意到移動到某個位置［相對于窗口的左上方］。雖然它能隨意移動，但有很多弊端，比如容器的大小它會隨字體的大小的改變而改變，從而可能會出現控件覆蓋控件的現象；又如在多語言中，我們都知道阿拉伯語到單詞大部分都比E文單詞都要長，如果從E語切換到阿拉伯語或其它語言時，固定容器的在水平方向將會發生伸縮等現象明顯是用戶所不能接受的。所以不推薦使用fixed container。下面是一個對Fixed Container的簡單實例：/**********************************

#include<gtk/gtk.h>
typedef struct ComButton_s
{
GtkWidget *m_pParentWidget;
GtkWidget *m_pSelfWidget;
guint32 m_nPox;
guint32 m_nPoy;
}ComButton_t;
gboolean _CallBackMove(GtkWidget *pHwidget, ComButton_t *pComButton)
{
static guint32 nPox = 0;
static guint32 nPoy = 0;
nPox += 5;
nPoy += 5;
pComButton->m_nPox = nPox;
pComButton->m_nPoy = nPoy;
gtk_fixed_move(GTK_FIXED(pComButton->m_pParentWidget), pComButton->m_pSelfWidget, pComButton->m_nPox, pComButton->m_nPoy);
return 0;
}
int main(int argc, char *argv[])
{
GtkWidget *pHwindow, *pHfixed, *pHbuttonOne, *pHbuttonTWO;
ComButton_t ComButton;
gtk_init(&argc, &argv);
pHwindow = gtk_window_new(GTK_WINDOW_TOPLEVEL);
gtk_window_set_title(GTK_WINDOW(pHwindow), "gtkfixedgtk+");
gtk_widget_set_size_request(pHwindow, 200, 250);
gtk_container_set_border_width(GTK_WINDOW(pHwindow), 10);
pHfixed = gtk_fixed_new();
pHbuttonOne = gtk_button_new_with_label("ButtonOne");
pHbuttonTWO = gtk_button_new_with_label("ButtonTwo");
gtk_fixed_put(GTK_FIXED(pHfixed), pHbuttonOne, 0,0);
gtk_fixed_put(GTK_FIXED(pHfixed), pHbuttonTWO, 80, 150);
ComButton.m_pParentWidget = pHfixed;
ComButton.m_pSelfWidget = pHbuttonOne;
g_signal_connect(pHbuttonOne, "clicked", G_CALLBACK(_CallBackMove), &ComButton);
gtk_container_add(GTK_WINDOW(pHwindow), pHfixed);
gtk_widget_show_all(pHwindow);
gtk_main();
return 0;
}Exapnder有擴展之意，expander容器只允許有一個子控件，通過點擊expander容器可以伸展或隱藏其子控件。以下是一個對Expander的簡單實例：
/**********************************

**FILE: expandergtk+.c
**DATE: 200905010 22:49
**AUTHOR: LAMMY
**VERSION: 0.0
**
**********************************/
#include<gtk/gtk.h>
int main(int argc, char *argv)
{
GtkWidget *pHwindow, *pHexpander, *pHlabel;
gtk_init(&argc, &argv) ;
pHwindow = gtk_window_new(GTK_WINDOW_TOPLEVEL);
gtk_window_set_title(GTK_WINDOW(pHwindow), "expandergtk+");
gtk_widget_set_size_request(pHwindow, 150, 250);
gtk_container_set_border_width(GTK_CONTAINER(pHwindow), 10);
pHexpander = gtk_expander_new_with_mnemonic("Click _Me For More");
pHlabel = gtk_label_new_with_mnemonic("Hide or Show Label");
gtk_container_add(GTK_EXPANDER(pHexpander), pHlabel);
//g_signal_connect();
gtk_container_add(GTK_WINDOW(pHwindow), pHexpander);
gtk_widget_show_all(pHwindow);
gtk_main();
return 0;
}
