如何获取光标的状态? [英] How to get the state of the cursor?

问题描述

我想知道 Python 3.8 中是否有任何方法可以读取游标类型，例如 win32gui 如何使用 win32gui.GetCursorInfo()，找到光标.以下是我所说的光标状态:

I was wondering if there was any way in Python 3.8 to read the cursor type like how win32gui could do with win32gui.GetCursorInfo(), Finding the id of the cursor. Below is what I mean by cursor state:

推荐答案

请在下面找到代码.

参考:https://www.iditect.com/how-to/10284849.html，但我稍微修改了一下:

reference: https://www.iditect.com/how-to/10284849.html, but I modified it a little bit:

from win32con import IDC_APPSTARTING, IDC_ARROW, IDC_CROSS, IDC_HAND, \
IDC_HELP, IDC_IBEAM, IDC_ICON, IDC_NO, IDC_SIZE, IDC_SIZEALL, \
IDC_SIZENESW, IDC_SIZENS, IDC_SIZENWSE, IDC_SIZEWE, IDC_UPARROW, IDC_WAIT

from win32gui import LoadCursor, GetCursorInfo

def get_current_cursor():
    curr_cursor_handle = GetCursorInfo()[1]
    return Cursor.from_handle(curr_cursor_handle)

class Cursor(object):
    @classmethod
    def from_handle(cls, handle):
        for cursor in DEFAULT_CURSORS:
            if cursor[1].handle == handle:
                return cursor[0] #DEFAULT_CURSORS.index(cursor) , Cursor.__init__
        return cls(handle=handle)

    def __init__(self, cursor_type=None, handle=None):
        if handle is None:
            handle = LoadCursor(0, cursor_type)
        self.type = cursor_type
        self.handle = handle

DEFAULT_CURSORS = (('APPSTARTING',Cursor(IDC_APPSTARTING)), ('ARROW',Cursor(IDC_ARROW)), ('CROSS',Cursor(IDC_CROSS)), ('HAND',Cursor(IDC_HAND)), \
       ('HELP',Cursor(IDC_HELP)), ('IBEAM',Cursor(IDC_IBEAM)), ('ICON',Cursor(IDC_ICON)), ('NO',Cursor(IDC_NO)), ('SIZE',Cursor(IDC_SIZE)),\
       ('SIZEALL', Cursor(IDC_SIZEALL)),('SIZENESW', Cursor(IDC_SIZENESW)), ('SIZENS',Cursor(IDC_SIZENS)), ('SIZENWSE',Cursor(IDC_SIZENWSE)),\
        ('SIZEWE', Cursor(IDC_SIZEWE)), ('UPARROW', Cursor(IDC_UPARROW)), ('WAIT',Cursor(IDC_WAIT)))

while(True):
    print(get_current_cursor())
