Matplotlib 图/图/画布/布局隐藏按钮。图片应该可以解释问题：我希望绘图的容器为右侧的按钮留出空间。
这是一个最小的工作代码示例，其中包含我尝试过的一些注释：
import sys

#self.figure.set_size_inches(5, 5, forward=True)

#self.figure.subplots_adjust(left=1, bottom=1, right=1, top=1, wspace=1, hspace=1)

main.show()
sys.exit(app.exec_())
您可以将按钮框添加到布局中，而不是将其放置在绝对坐标中，就像对画布和工具栏所做的那样。为此，您可以使用另一个包含画布和工具栏的小部件。该小部件可以放置在QHBoxLayout(); the QDialogButtonBox将在布局中添加到第二个。
