在Matplotlib中禁用关闭按钮可以通过以下步骤实现:
- 导入必要的库和模块:import matplotlib.pyplot as plt
from matplotlib import backend_bases
- 创建一个自定义的FigureCanvas类,继承自backend_bases.FigureCanvasBase,并重写close_event方法:class CustomFigureCanvas(backend_bases.FigureCanvasBase):
def close_event(self, guiEvent=None):
pass
- 创建一个自定义的FigureManager类,继承自backend_bases.FigureManagerBase,并重写destroy方法:class CustomFigureManager(backend_bases.FigureManagerBase):
def destroy(self, *args):
pass
- 创建一个自定义的Figure类,继承自plt.Figure,并重写manager属性:class CustomFigure(plt.Figure):
def __init__(self, *args, **kwargs):
super().__init__(*args, **kwargs)
self.canvas = CustomFigureCanvas(self)
self.manager = CustomFigureManager(self.canvas, 1)
- 使用自定义的Figure类创建图形,并显示:fig = CustomFigure()
plt.plot([1, 2, 3, 4])
plt.show()
通过以上步骤,关闭按钮将被禁用,用户将无法通过点击关闭按钮来关闭图形窗口。
