滚动条定义自定义样式时,我被如何更改滚动条的宽度所困扰。我注意到,当我从另一个主题复制元素TScrollbar.grip
时,宽度(厚度)会缩小,但当我查找元素选项style.element\u选项('My.Vertical.TScrollbar.grip')
时,宽度(厚度)会缩小
从tkinter导入*
从tkinter导入ttk
root=Tk()
style=ttk.style()
#从“clam”引擎导入元素。
创建样式元素(“My.Vertical.TScrollbar.droot”、“from”、“clam”)
style.element\u create(“My.Vertical.TScrollbar.thumb”、“from”、“clam”)
创建样式元素(“My.Vertical.TScrollbar.grip”、“from”、“clam”)
style.layout(“My.Vertical.TScrollbar”,
[('My.Vertical.TScrollbar.tour',{'children':
[('My.Vertical.TScrollbar.thumb',{'unit':'1','children':
[('My.Vertical.TScrollbar.grip',{'sticky':''}],
“粘性”:“nswe”},
'sticky':'ns'})])
style.configure(“My.Vertical.TScrollbar”,gripcount=0,background=“#464647”,troughcolor='#252526',borderwidth=2,
bordercolor='#252526',lightcolor='#252526',darkcolor='#252526')
容器=ttk.Frame(根)
画布=画布(容器)
scrollbar=ttk.scrollbar(容器,orient=“vertical”,command=canvas.yview,style=“My.vertical.TScrollbar”)
可滚动_frame=ttk.frame(画布)
可滚动的_frame.bind(
"",
lambda e:canvas.configure(
scrollregion=canvas.bbox(“全部”)
)
)
canvas.create_window((0,0),window=scrollable_frame,anchor=“nw”)
configure(yscrollcommand=scrollbar.set)
对于范围(50)内的i:
ttk.Label(可滚动的_框架,text=“示例滚动标签”).pack()
container.pack()
canvas.pack(side=“left”,fill=“both”)
滚动条包装(side=“right”,fill=“y”)
root.mainloop()
在对代码进行了一些外观更改以使其更具可读性之后,我能够在配置整体样式时通过指定一个箭头大小=
选项来更改滚动条的宽度。这是在style.configure()
调用中完成的,并显示在下面的行中,带有注释#感谢您的帮助。
