I have the following WPF window definition but the focus/lost focus events are not firing when I click away from the application, any ideas?
<Window x:Class="BevaClient.windowMain"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:l="clr-namespace:BevaClient"
xmlns:forms="clr-namespace:System.Windows.Forms;assembly=System.Windows.Forms"
Title="VPN Tool" Height="500" Width="370"
Focusable="True"
WindowStyle="None"
ResizeMode="NoResize"
Topmost="True"
Style="{StaticResource defaultWindow}"
Loaded="Window_Loaded"
GotFocus="Window_GotFocus"
LostFocus="Window_LostFocus">
I have tried setting topmost to false to see if this was the issue but it makes no difference.
Any advice on this issue would be very much appreciated.
Thanks,
David
Hook to Activated and Deactivated events instead.

I will improve my skill to developp in C#. I used to developp in C++ and Python.
I already train my self with consol application and I found the implementation of the POO paradigme very strong.
So I will try to produce UI like I can do in C++ and Python.
I follow this tutoriel : http://avaloniaui.net/docs/advanced-tutorial/
But I haven't the expected result like in the chapter : create-a-modern-window.
My windows buttons close, minimize and maximize are behind the panel. So It's hard to see this buttons. voir image
Of course, if I had Margin on the panel or if I remove panel, buttons is correctly visible.
It seems to me logic, that if I put a panel in front of something, it gives this result.
But the tutorial give nothing more and I check on the github : https://github.com/AvaloniaUI/Avalonia.MusicStore/tree/master/Avalonia.MusicStore and I found no difference with my code.
So do you have an idear of the problem or how to solves them ?
I work on Windows 10 with Avalovia 0.10.0.
My main window :
<Window xmlns="https://github.com/avaloniaui"

<ExperimentalAcrylicMaterial

</ExperimentalAcrylicBorder.Material>
</ExperimentalAcrylicBorder>
<Panel Margin="40">
<Button Content="Buy Music" Command="{Binding BuyMusicCommand}" HorizontalAlignment="Right" VerticalAlignment="Top">
<PathIcon Data="{StaticResource store_microsoft_regular}"/>
</Button>
</Panel>
</Panel>
</Window>
And my App.axaml
Application xmlns="https://github.com/avaloniaui"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="using:Avalonia.MusicStore"
x:Class="Avalonia.MusicStore.App">

<local:ViewLocator/>
</Application.DataTemplates>
<Application.Styles>
<FluentTheme Mode="Dark"/>
<StyleInclude Source="avares://Avalonia.MusicStore/Icons.axaml"/>
</Application.Styles>
</Application>
Thank you in advance for your help :)
Unfortunately there was a minor bug in 0.10 release.
Please set on your Window the following property:
ExtendClientAreaChromeHints="PreferSystemChrome"
Writing a program using WPF (with MahApps) In C# and wondering how can I disable a user being able to right click the TitleBar and brining up the window options menu?
Edit1: to confirm I would like to keep the min/max/close button on the bar, just remove the right click event
There is a new property in MahApps v2.x called ShowSystemMenuOnRightClick.

I've written an installer with a WPF UI. During the installation of a pre-requisite, the full screen WPF ui loses focus and task bar appears for some time. Currently below is how my window element looks.
<Window x:Class="CustomBA.MainView"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:resources="clr-namespace:KubeCustomBA.Resources"
mc:Ignorable="d"
Title="Installer" Width="1431" MinWidth="400" Height="588.9" MinHeight="300" ResizeMode="NoResize" WindowState="Maximized" ShowInTaskbar="False" Topmost="False" WindowStartupLocation="CenterOwner" WindowStyle="None" Background="#FF222222">
How can I avoid it from losing focus and showing the task bar? Any help would be much appreciated.
I'm trying to make a Button always stay on top even after minimize the application. Quite like a floating Button, when I click the Button the application hide, click it again the application show.
Window can set the Topmost="True" property, what about the Button?
You should make more one window with button, like this in XAML:
<Window AllowTransparency="True" ResizeMode="NoResize" WindowStyle="None"
Topmost="True" ShowInTaskbar="False" SizeToContent="WidthAndHeight"
Background="{x:Null}">
<Button x:Name="HideShowButton" Content="Restore" />
</Window>
Button cannot exist without window, but with these properies window will be invisible.
I am needing to make a custom window with WindowStyle.None, AllowsTransparency = true, etc.
and "resizeable"
how con help me to create resizeable this?
tanx...
The most simple solution is to implement the ResizeMode property, setting it to "CanResizeWithGrip".
<Window x:Class="TestProject.ScratchWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
Opacity="1.0"
ResizeMode="CanResizeWithGrip"
WindowStyle="None"
AllowsTransparency="True"
Title="Test Window">

</Window>
