How to create a dropdown menu with value and node text - WXPython

Question

In HTML, I can create drop-down menus, for example:

<select name=""> <option value="">TextNode #1</option> <option value="">TextNode #2</option> <select> 

Now I want something like this in wxPython. The problem is that I did not find a solution, because it allows me to put text, not value.

Example wxPython (Create Dropdown):

 DropDownList = [] Options = {0:"None",1:"All",2:"WTF?!!"} For Value, TextNode in Options: DropDownList.append( TextNode ) wx.ComboBox(panel,value="Select",choices=DropDownList) 

Well ... How can I add an addition to node text? .. Thank you!

You can use the ComboBox Append method to add additional information to each control element.

Here is a tutorial about the process: http://www.blog.pythonlibrary.org/2010/12/16/wxpython-storing-object-in-combobox-or-listbox-widgets/

And here is the sample code from the article:

 import wx ######################################################################## class Car: """""" #---------------------------------------------------------------------- def __init__(self, id, model, make, year): """Constructor""" self.id = id self.model = model self.make = make self.year = year ######################################################################## class MyForm(wx.Frame): #---------------------------------------------------------------------- def __init__(self): wx.Frame.__init__(self, None, wx.ID_ANY, "Tutorial") # Add a panel so it looks the correct on all platforms panel = wx.Panel(self, wx.ID_ANY) cars = [Car(0, "Ford", "F-150", "2008"), Car(1, "Chevrolet", "Camaro", "2010"), Car(2, "Nissan", "370Z", "2005")] sampleList = [] self.cb = wx.ComboBox(panel, size=wx.DefaultSize, choices=sampleList) self.widgetMaker(self.cb, cars) sizer = wx.BoxSizer(wx.VERTICAL) sizer.Add(self.cb, 0, wx.ALL, 5) panel.SetSizer(sizer) #---------------------------------------------------------------------- def widgetMaker(self, widget, objects): """""" for obj in objects: widget.Append(obj.make, obj) widget.Bind(wx.EVT_COMBOBOX, self.onSelect) #---------------------------------------------------------------------- def onSelect(self, event): """""" print "You selected: " + self.cb.GetStringSelection() obj = self.cb.GetClientData(self.cb.GetSelection()) text = """ The object attributes are: %s %s %s %s """ % (obj.id, obj.make, obj.model, obj.year) print text # Run the program if __name__ == "__main__": app = wx.App(False) frame = MyForm() frame.Show() app.MainLoop() 

Hope this helps!

According to my experience using wxWidgets in C ++, it is not supported natively.

What you can do is create a custom wxComboBox that inherits from wxComboBox. Your custom widget will be responsible for maintaining the display, perform a search each time you call SetValue , and do a reverse search each time you call GetValue
