Python 如何在tkinter.ttk.按钮中创建箭头并控制它';s码?
我想创建一个带有箭头的ttk.button,并改变箭头的大小 我发现“TButton”固有地包含样式名Python 如何在tkinter.ttk.按钮中创建箭头并控制它';s码?,python,button,tkinter,ttk,Python,Button,Tkinter,Ttk,我想创建一个带有箭头的ttk.button,并改变箭头的大小 我发现“TButton”固有地包含样式名TButton.leftarrow,而ttk.Style().layout()没有公开它 问题: (1) 如何激活这些样式名? (2) 如何控制.leftarrow的大小?我注意到它有一个arrowsize选项。我如何使用它 import tkinter as tk import tkinter.ttk as ttk class App(ttk.Frame): def __i
TButton.leftarrow
,而ttk.Style().layout()没有公开它
问题:
(1) 如何激活这些样式名?
(2) 如何控制.leftarrow
的大小?我注意到它有一个arrowsize
选项。我如何使用它
import tkinter as tk
import tkinter.ttk as ttk
class App(ttk.Frame):
def __init__(self, parent):
ttk.Frame.__init__(self, parent)
self.parent = parent
self.setStyle()
self.setWidget()
def setStyle(self):
style = ttk.Style()
print('Left.TButton layout are:', style.layout('Left.TButton'))
print("Left.TButton.leftarrow style.element_options: ",
style.element_options('Left.TButton.leftarrow'))
style.configure('Left.TButton', background='yellow')
style.configure('Left.TButton.leftarrow', background='white',
arrowsize=20)
def setWidget(self):
self.lbutton = ttk.Button(self.parent, style='Left.TButton')
self.lbutton2 = ttk.Button(self.parent, style='Left.TButton.leftarrow')
self.lbutton.pack()
self.lbutton2.pack()
if __name__ == '__main__':
root = tk.Tk()
root.title('Test')
root.geometry('200x50')
app = App(root)
app.pack(expand=1, fill='both')
在对ttk文档进行了大量尝试和深入研究后,我发现:
arrow
元素
作为自定义样式布局中焦点
元素的子元素
这将用于ttk.Button()
小部件。要做到这一点,我需要
使用ttk.Style().layout()
方法标签元素
样式t按钮
。arrowsleft
元素的arrowsize
选项似乎不起作用。我已经注释掉了这行不起作用的代码。但是,leftarrow
元素的arrowcolor
选项不起作用。为了调整标签
元素的字体大小,使用了ttk.Style().configuration
方法

#Define style Default.TButton with yellow background

#Approach 1
#==========
# Define style Left.TButton to show the following elements: leftarrow,
# padding, label
style.layout(
'Left1.TButton',[
('Button.focus', {'children': [
('Button.leftarrow', None),
('Button.padding', {'sticky': 'nswe', 'children': [
('Button.label', {'sticky': 'nswe'}
)]}
)]}
)]
)
#Change 3 options of the "arrow" element in style "Left.TButton"
style.configure('Left1.TButton.leftarrow',
background='white',
borderwidth=10,
arrowsize=20)
print('\nElement TButton.arrow and its options (after changing):')
print("background: ", style.lookup('Left1.TButton.arrow','background'))
print("borderwidth: ", style.lookup('Left1.TButton.arrow','borderwidth'))
print("arrowsize: ", style.lookup('Left1.TButton.arrow','arrowsize'))
#Approach 2
#==========
style.layout(
'Left2.TButton',[
('Button.focus', {'children': [
('Button.leftarrow', None),
('Button.padding', {'sticky': 'nswe', 'children': [
('Button.label', {'sticky': 'nswe'}

)]
)
style.configure('Left2.TButton',font=('','20','bold'), width=1, arrowcolor='white')
#style.configure('Left2.TButton', width=1, arrowcolor='white', arrowsize='20')
#option arrowsize does not work

我觉得你问的问题太多了,最简单的答案就是阅读
../Python3x/Lib/tkinter/ttk.py
或../Python/Python3x/tcl/tk8.6/ttk
下的源代码。我更愿意把这段代码放在上面评论一下。@Nae coderview和tcl有什么区别?我不明白,所以我问了这个问题。不同的是,在codereview中,你应该被建议在工作代码上使用更好的实践,或者如果你的代码在某些测试值上有错误,那么你可以。
