我正在开发一个带有文本输入小部件的gui，它可以根据表中的记录数重新生成。 我正在使用一个字段列表，每个字段都创建为一个条目小部件。 对于这些字段中的至少一个，我想设置一个组合框，其值可供用户选择。 我一直在玩添加一个组合框到根（我刚刚插入了一个样本）但是当我运行脚本时它没有出现。 我没有收到错误，gui显示所有输入框，但不显示组合框。 有没有人有任何想法：以下是一些代码：
import arcpy, tkMessageBox, ctypes, ttk from Tkinter import * mosaicD = r'C:\temp\temp.gdb\mapIndex_MD_test' mapIndexTbl = r'C:\temp\temp.gdb\mapIndexTestTable' formFields = ['County', 'Route', 'PMB', 'PME', 'Map_Sheet_Desc', 'HangingFileGroup', 'MapSubSet', 'MapSubSetStatus', 'Shtext', 'Status', 'SubStatus', 'MapDatum', 'Geo_Referenced_Datum', 'MapScale', 'CAD', 'DrawingDate', 'FileExtention','Original_MrSID_Filename'] fields = arcpy.ListFields(mapIndexTbl) with arcpy.da.SearchCursor(mosaicD,'name') as cursorB: for rowB in cursorB: inputValues = [] def fetch(entries): for entry in entries: field = entry[0] text = entry[1].get() inputValues.append(text) root.destroy() def makeform(root, fields): entries = [] for field in fields: row = Frame(root) lab = Label(row, width=20, text=field, anchor='w') ent = Entry(row) row.pack(side=TOP, fill=X, padx=5, pady=5) lab.pack(side=LEFT) ent.pack(side=RIGHT, expand=YES, fill=X) entries.append((field, ent)) return entries if __name__ == '__main__': root = Tk() root.iconbitmap(r'\\sv04docifs5\data5\vol2\Records\GIS\Logos\CT.ico') root.geometry('375x650') root.wm_title('Enter values for '+rowB[0]) cities = ('Toronto', 'Ottawa', 'Montreal', 'Vancouver', 'St. John') cblist = Frame(root) cbp3 = ttk.Labelframe(cblist, text='Pre-defined List') cb3 = ttk.Combobox(cbp3, values=cities, state='readonly') cb3.current(1) # set selection cb3.pack(side=LEFT, expand=YES, fill=X) # position and display cbp3.pack(in_=cblist, side=TOP, pady=5, padx=10) ents = makeform(root, formFields) root.bind('<Return>', (lambda event, e=ents: fetch(e))) b1 = Button(root, text='Submit', command=(lambda e=ents: fetch(e))) b1.pack(padx=5, pady=5,anchor=CENTER) #b2 = Button(root, text='Quit', command=root.quit) #b2.pack(side=LEFT, padx=5, pady=5) root.mainloop()I am developing a gui with text entry widgets that regenerate based on the number of a records in a table. I am using a list of fields that are each created as an entry widget. For at least one of these fields, I want to set up a combobox with values for the user to choose from. I've been playing around with adding a combobox to the root (I've just inserted a sample one for now) but it doesn't show up when I run the script. I don't get an error, the gui shows up with all the entry boxes, but not the combobox. Does anyone have any ideas: Here is some of the code:
import arcpy, tkMessageBox, ctypes, ttk from Tkinter import * mosaicD = r'C:\temp\temp.gdb\mapIndex_MD_test' mapIndexTbl = r'C:\temp\temp.gdb\mapIndexTestTable' formFields = ['County', 'Route', 'PMB', 'PME', 'Map_Sheet_Desc', 'HangingFileGroup', 'MapSubSet', 'MapSubSetStatus', 'Shtext', 'Status', 'SubStatus', 'MapDatum', 'Geo_Referenced_Datum', 'MapScale', 'CAD', 'DrawingDate', 'FileExtention','Original_MrSID_Filename'] fields = arcpy.ListFields(mapIndexTbl) with arcpy.da.SearchCursor(mosaicD,'name') as cursorB: for rowB in cursorB: inputValues = [] def fetch(entries): for entry in entries: field = entry[0] text = entry[1].get() inputValues.append(text) root.destroy() def makeform(root, fields): entries = [] for field in fields: row = Frame(root) lab = Label(row, width=20, text=field, anchor='w') ent = Entry(row) row.pack(side=TOP, fill=X, padx=5, pady=5) lab.pack(side=LEFT) ent.pack(side=RIGHT, expand=YES, fill=X) entries.append((field, ent)) return entries if __name__ == '__main__': root = Tk() root.iconbitmap(r'\\sv04docifs5\data5\vol2\Records\GIS\Logos\CT.ico') root.geometry('375x650') root.wm_title('Enter values for '+rowB[0]) cities = ('Toronto', 'Ottawa', 'Montreal', 'Vancouver', 'St. John') cblist = Frame(root) cbp3 = ttk.Labelframe(cblist, text='Pre-defined List') cb3 = ttk.Combobox(cbp3, values=cities, state='readonly') cb3.current(1) # set selection cb3.pack(side=LEFT, expand=YES, fill=X) # position and display cbp3.pack(in_=cblist, side=TOP, pady=5, padx=10) ents = makeform(root, formFields) root.bind('<Return>', (lambda event, e=ents: fetch(e))) b1 = Button(root, text='Submit', command=(lambda e=ents: fetch(e))) b1.pack(padx=5, pady=5,anchor=CENTER) #b2 = Button(root, text='Quit', command=root.quit) #b2.pack(side=LEFT, padx=5, pady=5) root.mainloop()最满意答案
组合框cb3包装在框架cbp3 。 该框架包含在框架cblist 。 无处在cblist上调用pack或grid 。 由于cblist是隐形的，它的孩子也是如此。
The combobox cb3 is packed in the frame cbp3. That frame is packed in frame cblist. Nowhere do you call pack or grid on cblist. Since cblist is invisible, so are its children.
