我想更改树视图标题的背景颜色.我已经确定了Treeview.Heading布局的元素选项,负责这个:Treeheading.cell.问题是这个设置不适用于’vista’主题(由于我假设的绘图问题).
工作代码(虽然主题看起来很可怕):
from tkinter import *
from tkinter import ttk
p=Tk()
separator = PanedWindow(p,bd=0,bg="#22",sashwidth=2)
separator.pack(fill=BOTH, expand=1)
_frame = Frame(p,bg="#383838")
t=ttk.Treeview(_frame)
t["columns"]=("first","second")
t.column("first",anchor="center" )
t.column("second")
t.heading("first",text="first column")
t.heading("second",text="second column")
t.insert("",0,"dir1",text="directory 1")
t.insert("dir1","end","dir 1",text="file 1 1",values=("file 1 A","file 1 B"))
id=t.insert("","end","dir2",text="directory 2")
t.insert("dir2","end",text="dir 2",values=("file 2 A","file 2 B"))
t.insert(id,"end",text="dir 3",values=("val 1 ","val 2"))
t.insert("",0,text="first line",values=("first line 1","first line 2"))
t.tag_configure("ttk",foreground="black")
ysb = ttk.Scrollbar(orient=VERTICAL, command= t.yview)
xsb = ttk.Scrollbar(orient=HORIZONTAL, command= t.xview)
t['yscroll'] = ysb.set
t['xscroll'] = xsb.set
print(ttk.Style().theme_names())
ttk.Style().theme_use('default')
ttk.Style().configure("Treeview", background="#383838",foreground="white")
ttk.Style().configure("Treeview.Heading",background = "blue",foreground="Black")
p.configure(background='black')
t.grid(in_=_frame, row=0, column=0, sticky=NSEW)
ysb.grid(in_=_frame, row=0, column=1, sticky=NS)
xsb.grid(in_=_frame, row=1, column=0, sticky=EW)
_frame.rowconfigure(0, weight=1)
_frame.columnconfigure(0, weight=1)
separator.add(_frame)
w = Text(separator)
separator.add(w)
p.mainloop()
我尝试使用’vista’主题:
ttk.Style().element_create("Treeheading.cell","from","default")
ttk.Style().configure("Treeview", background="#383838",foreground="white")
ttk.Style().configure("Treeview.Heading",background = "Blue")
element_create在此问题的其他实例中工作但具有不同的小部件.
谢谢,任何帮助将不胜感激.
在python 3中工作.此外,代码不是我的,我发现它并用它来测试.
