    <p>attrubuI'm new to python but don't know how to solve this:</p> <pre><code>import wx class myclass(wx.Frame): def __init__(self,parent,id): wx.Frame.__init__(self,parent,id,'Frame',size=(300,200)) panel=wx.Panel(self) button=wx.Button(panel,label="click me",size=(120,60)) self.Bind(wx.EVT_BUTTON, self.clickbutton, button) value=1 def clickbutton(self, event): if self.value == 1: print("success") if __name__=='__main__': app=wx.PySimpleApp() frame=myclass(parent=None,id=-1) frame.Show() app.MainLoop() </code></pre> <p>When I click the button I receive this error: "AttributeError: 'myclass' object has no attribute 'value'". What am I doing wrong? / How do I import "value" into my "clickbutton"-function?</p> <p>Edit: OK, this one was solved. After that I wanted to modify it a little:</p> <pre><code> self.dropdown=wx.Choice(panel,pos=(130,60)) list = ['banana', 'apple', 'strawberry'] self.dropdown.AppendItems(strings=list) def clickbutton(self, event): if self.dropdown.GetStringSelection() == 'apple': print("success") </code></pre> <p>Actually this works.... but it took me a long time to figure out that I have to use "GetStringSelection()" in the last but one line. How can i display a list with possible attributes (like "GetStringSelection()") for "wx.Choice" (and other wx-classes) ? Or does a good website for this exists?</p> <p>Edit 2: Thanks again! And I have a last question (sorry for asking step by step):</p> <pre><code>dir(wx.Choice) </code></pre> <p>works, but I have a given code with an obejct called "VarDecl". For this I get an error if I ask</p> <pre><code>dir(wx.VarDecl) </code></pre> <p>I'm lookin for an attribute like "HasChanged" for this VarDecl-object. </p> <pre><code>Traceback (most recent call last): File [...] if self.theVariable.HasChanged(): AttributeError: 'VarDecl' object has no attribute 'HasChanged' </code></pre> <p>Edit3: OK, I think it has nothing to do with "wx", I think it comes from "re". (or still "wx"? I'm confused) </p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
