如何防止 GtkWindow 增长？

Question

这是我的代码：

#include<gtk/gtk.h>
int main(int argc,char**argv)
{
   GtkWidget* window, *button, *grid;
   gtk_init(&argc,&argv);

   window = gtk_window_new(GTK_WINDOW_TOPLEVEL);
   gtk_window_set_default_size(GTK_WINDOW(window),100,100);
   g_signal_connect(G_OBJECT(window),"destroy",G_CALLBACK(gtk_main_quit),NULL);
   //gtk_container_set_border_width(GTK_CONTAINER(window),10);
   gtk_window_set_resizable(GTK_WINDOW(window), FALSE);

   grid = gtk_grid_new();
   button = gtk_button_new_with_label("1");
   gtk_grid_attach(GTK_GRID(grid), button, 0,0, 100, 1);
   gtk_grid_set_column_homogeneous(GTK_GRID(grid), TRUE);
   gtk_grid_set_row_homogeneous(GTK_GRID(grid), TRUE);

   button = gtk_button_new_with_label("1");
   gtk_grid_attach(GTK_GRID(grid), button,0, 1, 10, 1);
   gtk_container_add(GTK_CONTAINER(window), grid);
   gtk_widget_show_all(window);
   gtk_main();
   return 0;
}

这段代码的结果是： gtk_grid_attach(GTK_GRID(grid), button,0, 1, 100, 1)

当我将 gtk_grid_attach(GTK_GRID(grid), button,0, 1, 100, 1) 更改为 gtk_grid_attach(GTK_GRID(grid), button ,0, 1, 200, 1) 那么这段代码的结果是： gtk_grid_attach(GTK_GRID(grid), button,0, 1, 200, 1)

为什么window的宽度变大了？我发现 window 的大小可能会随着函数 gtk_grid_attach() 的变化而变化。那么如何解决呢？

Answer 1

Why does the width of window increase?

您已使用

   gtk_grid_set_column_homogeneous(GTK_GRID(grid), TRUE);
   gtk_grid_set_row_homogeneous(GTK_GRID(grid), TRUE);

这意味着网格中的每个单元格将具有相等的宽度和高度，这将与嵌入的最大小部件相同。所以如果你有更多的单元格，网格将进一步增长，因此 window 宽度增加

I find that the size of window may be varied with the function gtk_grid_attach(). So how to solve it?

我不知道你的用例是什么。但是您可以取消设置同类属性 and/or 在附加子项时使用真实的网格宽度和高度。
