我想用 GLade 在 GTK 应用程序的左侧创建一个标签栏。我想像这样获得可调整大小的标签栏区域:
但我找不到笔记本小部件的调整大小选项。
有人知道我如何使用 GLade 做到这一点或有任何想法吗？
最佳答案
GtkNotebook 的选项卡区域不能由用户调整大小。虽然有解决方法。一种解决方案是从 GtkNotebook 中删除选项卡并模拟带有按钮的选项卡栏。这样您就可以将两者分开并将它们包含在 GtkPaned 中。
遵循这种方法的一个简单的 glade 文件(名为 myui.glade):

要在 GtkNotebook 页面之间切换，我们必须处理按钮点击并切换到相应的页面。
该行为的一个简单实现可以是(命名为 main.c):
#include <gtk/gtk.h>
void on_page1_button_clicked (GtkButton *button, gpointer user_data) {
GtkNotebook *notebook = GTK_NOTEBOOK(user_data);
gtk_notebook_set_current_page(notebook, 0);
}
void on_page2_button_clicked (GtkButton *button, gpointer user_data) {
GtkNotebook *notebook = GTK_NOTEBOOK(user_data);
gtk_notebook_set_current_page(notebook, 1);
}
void on_page3_button_clicked (GtkButton *button, gpointer user_data) {
GtkNotebook *notebook = GTK_NOTEBOOK(user_data);
gtk_notebook_set_current_page(notebook, 2);
}
int main(int argc, char *argv[]) {
GtkWidget *page1;
GtkWidget *page2;
GtkWidget *page3;
GtkWidget *window;
GtkWidget *notebook;
GtkBuilder *builder;
gtk_init (&argc,&argv);
builder = gtk_builder_new_from_file("myui.glade");
page1 = GTK_WIDGET(gtk_builder_get_object(builder, "page1"));
page2 = GTK_WIDGET(gtk_builder_get_object(builder, "page2"));
page3 = GTK_WIDGET(gtk_builder_get_object(builder, "page3"));
window = GTK_WIDGET(gtk_builder_get_object(builder, "window1"));
notebook = GTK_WIDGET(gtk_builder_get_object(builder, "notebook1"));
g_signal_connect (page1, "clicked", G_CALLBACK(on_page1_button_clicked), notebook);
g_signal_connect (page2, "clicked", G_CALLBACK(on_page2_button_clicked), notebook);
g_signal_connect (page3, "clicked", G_CALLBACK(on_page3_button_clicked), notebook);
g_signal_connect (window, "destroy", G_CALLBACK(gtk_main_quit), NULL);
gtk_widget_show_all(GTK_WIDGET(window));
gtk_main();
return 0;
}
编译:
gcc -o notebook main.c `pkg-config --cflags --libs gtk+-3.0`
