  1. POIronPython & WPF: Binding a checkbox's IsChecked property to a class member variable
    primarykey
    data
    text
    <p>I've seen many similar questions on how to get data binding working with a checkbox, but <strong>all</strong> of the examples I've seen are in C# and I can't seem to make the leap to convert it to IronPython. I have a checkbox defined in a window thusly:</p> <pre><code>&lt;Window xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Name="Test" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" mc:Ignorable="d"&gt; &lt;DockPanel&gt; &lt;CheckBox Name="bindtest" IsChecked="{Binding Path=o1checked, Mode=OneWay}"&gt;&lt;/CheckBox&gt; &lt;Button Content="Toggle" Name="Toggle" Padding="5"&gt;&lt;/Button&gt; &lt;/DockPanel&gt; &lt;/Window&gt; </code></pre> <p>And I want its IsChecked value to automatically update when <code>self.o1checked</code> is toggled in the following class:</p> <pre><code>class MaikoCu64(object): def __init__(self): self.o1checked = False ui.win['Button']['Toggle'].Click += self.Toggle_OnClick def Toggle_OnClick(self, sender, event): self.o1checked = not self.o1checked </code></pre> <p>(That <code>ui</code> object is a class that has the xaml loaded into it as a dictonary of ui controls. See <a href="http://www.ironpython.info/index.php/XAML_GUI_Events_Example" rel="nofollow">here</a>)</p> <p>So how do I make this happen? After hours of reading through the MSDN binding documentation (also all in C#) I've tried adding this:</p> <pre><code>import System myBinding = System.Windows.Data.Binding("o1checked") myBinding.Source = self myBinding.Mode = System.Windows.Data.BindingMode.OneWay ui.win['CheckBox']['bindtest'].SetBinding(System.Windows.Controls.CheckBox.IsCheckedProperty, myBinding) </code></pre> <p>It doesn't work, but it seems like it makes at least some sense. Am I on the right track?</p>
