Question

我想为我的电脑制作遥控器。基本上我只需要点击一下按钮就可以运行一个命令。在guide之后，我设法构建了layout，这是我梦寐以求的一切。但是当我尝试使用

运行它时

gtkdialog -g test.glade -p MainWindow

这种情况发生了

(gtkdialog:18284): libglade-WARNING **: Expected <glade-interface>.  Got <interface>.
(gtkdialog:18284): libglade-WARNING **: did not finish in PARSER_FINISH state
(gtkdialog:18284): libglade-CRITICAL **: glade_xml_get_widget: assertion 'self != NULL' failed
(gtkdialog:18284): ERROR **: Can not load 'MainWindow' from file 'test.glade'

之后没有真正发生.. 有更简单的方法吗？

我的想法是将该程序放在单独的虚拟屏幕上并使用我的手机访问它。

这是林间空地文件

gtkbuilder是一个旧的死项目，不支持glade使用的现代python语法。应该避免这种情况，您应该使用具有官方绑定的gjs或{{1}}等语言来创建应用程序。

使用空格的bash上的GUI
