如何向 PyGObject 3 添加内嵌图像？

如何解决如何向 PyGObject 3 添加内嵌图像？

我想将内嵌图像放入我的 PyGObject 3 程序中，这样它们就不必从磁盘加载。 YoLinux shows how to edit an XPM file so its text can be inserted into Python code. John Finlay 的免费电子书“PyGTK 2.0 教程”给出了两个代码示例。所有这些都是针对 PyGTK 2 而不是 gi / PyGObject 3。它不必是 XPM 数据，这只是在 PyGTK 2 中实现的一种简单方法。以下是示例 pixmap.py 的编辑版本

如何将此工作示例更改为 PyGObject 3，或者是否还有其他工作示例可以更轻松地将内嵌图像添加到 PyGObject 3？

import pygtk
pygtk.require('2.0')
import gtk

xpm_data = [
"16 16 3 1","       c None",".      c #000000000000","X      c #FFFFFFFFFFFF","                ","   ......       ","   .XXX.X.      ","   .XXX.XX.     ","   .XXX.XXX.    ","   .XXX.....    ","   .XXXXXXX.    ","   .........    ","                "
]

class pixmapExample:
    def close_application(self,widget,event,data=None):
        gtk.main_quit()
        return False

    def __init__(self):
        window = gtk.Window(gtk.WINDOW_TOPLEVEL)
        window.connect("delete_event",self.close_application)
        window.set_border_width(10)
        window.show()

        pixmap,mask = gtk.gdk.pixmap_create_from_xpm_d(window.window,None,xpm_data)
        
        image = gtk.Image()
        image.set_from_pixmap(pixmap,mask)
        image.show()

        button = gtk.Button()
        button.add(image)
        window.add(button)
        button.show()

def main():
    gtk.main()
    return 0

if __name__ == "__main__":
    pixmapExample()
    main()

解决方法

这是您示例到 PyGObject 3 的直接移植。该解决方案使用 GdkPixbuf.Pixbuf.new_from_xpm_data() 函数来创建图像。

import gi
gi.require_version('Gtk','3.0')
from gi.repository import Gtk,GdkPixbuf

xpm_data = [
"16 16 3 1","       c None",".      c #000000000000","X      c #FFFFFFFFFFFF","                ","   ......       ","   .XXX.X.      ","   .XXX.XX.     ","   .XXX.XXX.    ","   .XXX.....    ","   .XXXXXXX.    ","   .........    ","                "
]

class PixmapExample:
    def close_application(self,widget,event,data=None):
        Gtk.main_quit()
        return False

    def __init__(self):
        window = Gtk.Window()
        window.connect("delete_event",self.close_application)
        window.set_border_width(10)
        window.show()

        pixbuf = GdkPixbuf.Pixbuf.new_from_xpm_data(xpm_data)
        image = Gtk.Image()
        image.set_from_pixbuf(pixbuf)
        image.show()

        button = Gtk.Button()
        button.add(image)
        window.add(button)
        button.show()

def main():
    Gtk.main()
    return 0

if __name__ == "__main__":
    PixmapExample()
    main()

在研究了 bohrax 的答案后，我拼凑出了我能想到的最简单的版本。

import gi
gi.require_version('Gtk',"                "
]

window = Gtk.Window()

image = Gtk.Image()
pixbuf = GdkPixbuf.Pixbuf.new_from_xpm_data(xpm_data)
image.set_from_pixbuf(pixbuf)

window.add(image)

window.connect("destroy",Gtk.main_quit)

window.show_all()
Gtk.main()
