How to extend instead of overriding WPF Styles

August 1, 2023 by Tarik

I had the same problem. I used Zack’s answer and improved it like following so if you don’t specify a style the overridden default is still taken in account. It’s basically what you would have done but just once in the ResourceDictionary. <Window x:Class=”TestWpf.RandomStuffWindow” xmlns=”http://schemas.microsoft.com/winfx/2006/xaml/presentation” xmlns:x=”http://schemas.microsoft.com/winfx/2006/xaml” Title=”Random Stuff Window”> <Window.Resources> <ResourceDictionary> <!– Default Label style … Read more

You might want to take a look at the ItemsPanel property: Gets or sets the template that defines the panel that controls the layout of items. Example: <ItemsControl> <ItemsControl.ItemsPanel> <ItemsPanelTemplate> <WrapPanel /> </ItemsPanelTemplate> </ItemsControl.ItemsPanel> </ItemsControl> And you can set it in a Style as follows: <Style TargetType=”ItemsControl”> <Setter Property=”ItemsPanel”> <Setter.Value> <ItemsPanelTemplate> <WrapPanel /> </ItemsPanelTemplate> </Setter.Value> … Read more

Python PEP: blank line after function definition?

July 30, 2023 by Tarik

Read Docstring Conventions. It says that even if the function is really obvious you have to write a one-line docstring. And it says that: There’s no blank line either before or after the docstring. So I would code something like def hello_function(): “””Return ‘hello’ string.””” return ‘hello’

Change Drawable Based on Theme

July 29, 2023 by Tarik

Seems like I’m always just a Google search or two away from my answers. The solution is: in styles.xml <attr name=”buttonface_picture” format=”reference”/> then in the actual theme: <item name=”buttonface_picture”>@drawable/buttonface_picture_dark</item> or <item name=”buttonface_picture”>@drawable/buttonface_picture_light</item> Then, in the menu.xml: <item android:id=”@+id/menu_attach_existing_picture” android:icon=”?attr/buttonface_picture” android:showAsAction=”always” android:title=”@string/menu_attach_existing_picture”> </item> The Accessing Resources Page combined with this SO eventually got it to click … Read more

Why can’t I style a DataGridTextColumn?

July 27, 2023 by Tarik

You can’t style the DataGridTextColumn because DataGridTextColumn does not derive from FrameworkElement (or FrameworkContentElement). Only FrameworkElement, etc supports styling. When you attempt to create a style in XAML for any type that is not a FrameworkElement or FrameworkContentElement you get that error message. How do you solve this? As with any problem, where there is … Read more

WPF TabItem Header Styling

July 24, 2023 by Tarik

Try this style instead, it modifies the template itself. In there you can change everything you need to transparent: <Style TargetType=”{x:Type TabItem}”> <Setter Property=”Template”> <Setter.Value> <ControlTemplate TargetType=”{x:Type TabItem}”> <Grid> <Border Name=”Border” Margin=”0,0,0,0″ Background=”Transparent” BorderBrush=”Black” BorderThickness=”1,1,1,1″ CornerRadius=”5″> <ContentPresenter x:Name=”ContentSite” VerticalAlignment=”Center” HorizontalAlignment=”Center” ContentSource=”Header” Margin=”12,2,12,2″ RecognizesAccessKey=”True”> <ContentPresenter.LayoutTransform> <RotateTransform Angle=”270″ /> </ContentPresenter.LayoutTransform> </ContentPresenter> </Border> </Grid> <ControlTemplate.Triggers> <Trigger Property=”IsSelected” Value=”True”> … Read more

When using Theme.MaterialComponents.Light.NoActionBar style, setting Button Background has no effect

July 23, 2023 by Tarik

If you want a true Button, but one that you can modify like the framework Button (instead of the MaterialButton), then you can explicitly specify the framework version in your layout file. Replace this: <Button android:id=”@+id/item_popupwindows_cancel” … /> with this: <android.widget.Button android:id=”@+id/item_popupwindows_cancel” … /> This will give you what it says on the tin: an … Read more
