wxPython | wx.ToolBar 中的 GetToolState()函数

在本文中，我们将学习与 wxPython 的 wx.ToolBar 类关联的 GetToolState()函数。 GetToolState()函数获取切换工具的开/关状态。如果工具已打开，则返回 True，否则返回 False。它只需要 toolId 作为参数来识别 Tool。

Syntax:

Parameter :

Parameter	Input Type	Description
toolid	int	An integer by which the tool may be identified in subsequent operations.

Return Type:

代码示例：

wx.ToolBar.GetToolState(self, toolId)

输出：

代码示例 2：

bool

输出：
