Question

如果有人可以帮助我完成在dxf中生成图形的任务，我将感到非常高兴。即使没有gui一切正常，我也很难从tkinter输入字段获取输入。我正在使用= self.a.get（），但似乎它没有从输入中获取数字。这是我所做的：

from tkinter import *
import dxfwrite
from dxfwrite import DXFEngine as dxf

class GUI(Frame):

  def __init__(self, master=None):
    Frame.__init__(self, master)
    self.grid()
    self.fnameLabel = Label(master, text="height: ")
    self.fnameLabel.grid(row=2, column=0, sticky=W)
    self.a = DoubleVar()
    self.a = Entry(master)
    self.a.grid(row=2, column=1, sticky=W)
    self.submitButton = Button(master, command=self.buttonClick, 
    text="generate drawing")
    self.submitButton.grid()

  def buttonClick(self):
    a = self.a.get()
    drawing = dxf.drawing('test111.dxf')
    drawing.add_layer('lines')

    a = float()
    b = float()
    b = 0.05
    while True:
      drawing.add(dxf.line((0.03, b), (a, b), color=40, layer='lines'))
      b += 0.15
      if b >= a + 1:
        break

    drawing.save()

if __name__ == "__main__":  
  guiFrame = GUI()
  guiFrame.mainloop()

当您将字符串转换为浮点型时，您必须告诉函数要转换的内容。如果不提供参数，则float函数将返回0.0。

               <div class="row">
                    <div class="col-md-6">
                        <div class="form-group">
                            <label>Customer</label>
                            @Html.DropDownListFor(x => x.CustomerId, new SelectList(Model.CustomerList, "Id", "UserName"), new { @class = "form-control select2", @id="emailadd", @placeholder = "" })

                        </div>
                    </div>
                    <div class="col-md-6">
                        <label></label>
                        <button type="button" class="btn btn-block btn-success" id="okbutton" style="width:60px;">OK</button>
                    </div>
                    <div id="voucher-result"></div>
                </div>

我无法在tkinter中解决条目浮动问题并使用它
