GTK改变窗口的背景图像 [英] GTK changing background image of window

问题描述

我该如何实现它？我一直在寻找它30分钟，发现不起作用或恶劣工作的例子。我只是想改变窗口的背景图像而不改变其他对话窗口的背景等等？但我希望按钮和标签在该背景上透明。

解决方案

我找到了一个适用于我的python示例：

http://islascruz.org/html/index.php/blog/show/Image-as-background-in-a-Gtk-Application..html p>

代码

 ＃！/ usr / bin / env python 
 import gtk 
 
 def draw_pixbuf（widget，event）：
 path ='/home/markuz/wallpapers/WMwall1024x768.gif'
 pixbuf = gtk.gdk.pixbuf_new_from_file（path）
 widget.window.draw_pixbuf（widget.style.bg_gc [gtk.STATE_NORMAL]，pixbuf，0，0，0,0）
 
 window = gtk .Window（）
 window.set_title（'Drawing Test'）
 window.set_size_request（640,480）
 window.connect（'destroy'，gtk.main_quit）
 hbbox = gtk .HButtonBox（）
 window.add（hbbox）
 hbbox。 connect（'expose-event'，draw_pixbuf）
 button = gtk.Button（'Press Me！'）
 hbbox.pack_start（button，True，False，10）
 window.show_all ）
 
 gtk.main（）
  

我还在：

http：// www .gtkforums.com / viewtopic.php？t = 446

代码

  GtkWidget * SetupWindow（gchar * data，gboolean Transient）
 {
 GdkPixmap * background; 
 GdkPixbuf * pixbuf; 
 GdkScreen *我们的屏幕; 
 GdkColormap * colormap; 
 GtkStyle *风格; 
 GdkColor fg; 
 GdkColor bg; 
 GError * error = NULL; 
 GdkRectangle * rect; 
 GtkWidget *窗口; 
 
 pixbuf = gdk_pixbuf_new_from_file（pics / fb.png，& error）; 
 if（error！= NULL）{
 if（error-> domain == GDK_PIXBUF_ERROR）{
 g_print（Pixbuf相关错误：\\\
）; 
 
 if（error-> domain == G_FILE_ERROR）{
 g_print（File Error：Check file permissions and state：\\\
）; 
} 
 
 g_printerr（％s \ n，error [0] .message）; 
 exit（1）; 
} 
 gdk_pixbuf_render_pixmap_and_mask（pixbuf，& background，NULL，0）; 
 style = gtk_style_new（）; 
 style-> bg_pixmap [0] = background; 
 window = gtk_window_new（GTK_WINDOW_TOPLEVEL）; 
 gtk_window_set_title（GTK_WINDOW（window），data）; 
 // gtk_window_maximize（GTK_WINDOW（window））; 
 gtk_window_set_modal（GTK_WINDOW（window），TRUE）; 
 gtk_window_set_default_size（GTK_WINDOW（window），640,480）; 
 gtk_widget_set_style（GTK_WIDGET（window），GTK_STYLE（style））; 
 gtk_window_set_position（GTK_WINDOW（window），GTK_WIN_POS_CENTER_ALWAYS）; 
 gtk_container_set_border_width（GTK_CONTAINER（window），14）; 
 if（Transient == TRUE）
 gtk_window_set_transient_for（GTK_WINDOW（window），GTK_WINDOW（mainwindow））; 
 gtk_widget_show（window）; 
 return（window）; 
} 
  

但我没有试过它。

how can I achieve it? I was searching for it for like 30 minutes and found examples which don't work or work in bad way. I simply want to change background image of window without changing bakgrounds of other dialogs windows etc? But I want buttons and labels to be transparent on that background.

解决方案

I found a python example that worked for me at:

http://islascruz.org/html/index.php/blog/show/Image-as-background-in-a-Gtk-Application..html

Code

#!/usr/bin/env python
import gtk

def draw_pixbuf(widget, event):
        path = '/home/markuz/wallpapers/WMwall1024x768.gif'
        pixbuf = gtk.gdk.pixbuf_new_from_file(path)
        widget.window.draw_pixbuf(widget.style.bg_gc[gtk.STATE_NORMAL], pixbuf, 0, 0, 0,0)

window = gtk.Window()
window.set_title('Drawing Test')
window.set_size_request(640,480)
window.connect('destroy',gtk.main_quit)
hbbox = gtk.HButtonBox()
window.add(hbbox)
hbbox.connect('expose-event', draw_pixbuf)
button = gtk.Button('Press Me!')
hbbox.pack_start(button, True, False, 10)
window.show_all()

gtk.main()

I also found a C example at:

http://www.gtkforums.com/viewtopic.php?t=446

Code

GtkWidget *SetupWindow(gchar *data,gboolean Transient)
{
    GdkPixmap *background;
    GdkPixbuf *pixbuf;
    GdkScreen *ourscreen;
    GdkColormap *colormap;
    GtkStyle *style;
    GdkColor fg;
    GdkColor bg;
    GError *error = NULL;
    GdkRectangle *rect;
    GtkWidget *window;

    pixbuf = gdk_pixbuf_new_from_file ("pics/fb.png",&error);
    if (error != NULL) {
        if (error->domain == GDK_PIXBUF_ERROR) {
            g_print ("Pixbuf Related Error:\n");
        }
        if (error->domain == G_FILE_ERROR) {
            g_print ("File Error: Check file permissions and state:\n");
        }

        g_printerr ("%s\n", error[0].message);
        exit(1);
    }
    gdk_pixbuf_render_pixmap_and_mask (pixbuf, &background, NULL, 0);
    style = gtk_style_new ();
    style->bg_pixmap[0] = background;
    window = gtk_window_new (GTK_WINDOW_TOPLEVEL);
    gtk_window_set_title (GTK_WINDOW (window), data);
    // gtk_window_maximize(GTK_WINDOW(window));
    gtk_window_set_modal (GTK_WINDOW (window),TRUE);
    gtk_window_set_default_size(GTK_WINDOW(window),640,480);
    gtk_widget_set_style (GTK_WIDGET(window), GTK_STYLE(style));
    gtk_window_set_position(GTK_WINDOW(window),GTK_WIN_POS_CENTER_ALWAYS);
    gtk_container_set_border_width(GTK_CONTAINER(window), 14);
    if(Transient==TRUE)
    gtk_window_set_transient_for(GTK_WINDOW (window),GTK_WINDOW(mainwindow));
    gtk_widget_show (window);
    return(window);
}

But I didn't try it.
