I want to build a WPF Application that, when started, only has a tray Icon. If the User interacts with Menu Entries from the Tray's Context Menu, there will be Windows.
I need to load the MainWindow though, so I can listen to Clipboard Changed Events. But I don't want to show it.
I tried:
<Window x:Class="ClipboardListener.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:tb="http://www.hardcodet.net/taskbar"
Title="Should not see me"
ShowInTaskbar="False" Visibility="Collapsed" Opacity="100"
Width="320" Height="240">
But it still shows up? Setting Visibility to Hidden does not work for me since I need some Window to register the Clipboard Event Listener with the WinAPI.
Any Ideas?
I've recently had very similar task. All my attempts to make Window invisible, my googling, my stackoverflowing etc. failed. Finally I had a feeling that invisible window is something that should not be in WPF on some reason. It would be an easy task if there was TrayIcon control like in WinForms. Unfortunately, WPF does not have TrayIcon. This leads to the one that is present in WinForms.
Here's a good article on the issue. And my code that uses this dll:
<Window x:Class="ScannerClientWpf.TrayIcon"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:ni="clr-namespace:Hardcodet.Wpf.TaskbarNotification;assembly=Hardcodet.Wpf.TaskbarNotification"
Title="TrayIcon" WindowStyle="None" AllowsTransparency="True" Background="Transparent" ShowActivated="False" ShowInTaskbar="False" >
<Grid>
<ni:TaskbarIcon IconSource="/ScannerClient;component/app.ico"
ToolTipText="ScannerClient">
<ni:TaskbarIcon.ContextMenu>
<ContextMenu>
<MenuItem Header="Close" Click="MenuItem_Click"/>
</ContextMenu>
</ni:TaskbarIcon.ContextMenu>
</ni:TaskbarIcon>
</Grid>

I've written a small application in WPF that shows 2 windows. One, which is basically a transparent window with no borders, for sharing a part of my screenin MS Teams and one with some resizing options.
I have a very big screen on my PC and when I share my desktop I see all participants starting to move closer to their screen because the image is sized down to their screen and makes it very hard to read.
I've seen several application solving this problem but most of them are a bit cumbersome. I'm a developer so I though: "I can do that too".
Now when I share my partial window everything works fine but.... when I f.i. right click somewhere to call the context menu, I see the menu perfectly but on the shared screens a box with no content appears.
This is probably a tough one but who can tell me what to do. Here's the mainpage.xaml:
<Window x:Class="PartialShare.MainWindow"
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"
Title="Partial Share (share this one)"
x:Name="PartialShare"
d:AllowsTransparency="true"
mc:Ignorable="d"
BorderThickness="1"
BorderBrush="Blue"
MaxHeight="{x:Static SystemParameters.MaximizedPrimaryScreenHeight}"
Height="1000"
Width="1000"
ResizeMode="CanResizeWithGrip"
Opacity="1"
Topmost="true"
AllowsTransparency="True"
WindowStyle="None">
<WindowChrome.WindowChrome>
<WindowChrome
CaptionHeight="30"
CornerRadius ="10"
ResizeBorderThickness="20"
GlassFrameThickness="0">
</WindowChrome>
</WindowChrome.WindowChrome>
<Window.Background>
<SolidColorBrush Opacity="0.0" Color="Transparent" />
</Window.Background>
</Window>
This is what I see:
And this is what they see in MS Teams:
The project is open source on GitHub. You can download it here: https://github.com/PaulSinnema/PartialShare
This concerns WPF. The problem is that my MediaElement (actually a GIF) doesn't show up at runtime (so I only get an empty screen), even though it shows perfectly in the design mode. Before citing the code I note the following:
The GIF-file in question has been added to the solution.
Its BuildAction property is set to Resource (I've checked).
When I replace the MediaElement by an Image element (and either use the same GIF-file or replace that source-file by a .png file), the image/GIF does display at runtime. Just not when it's used as a MediaElement.
Closing and re-starting Visual Studio doesn't help.
As I said (and just to emphasize, if I may), the GIF image does display in the design mode part of the screen - just not at runtime.
And here's the code:
<Window x:Class="Testing.TestWindow"
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:local="clr-namespace:Testing"
mc:Ignorable="d"
Title="TestWindow" WindowState="Maximized">
<StackPanel>
<MediaElement Source="pack://application:,,,/Images/untitled.gif" Stretch="Fill" Visibility="Visible" />
</StackPanel>
</Window>
Thanks.
I am developing an application in WPF using MahApps.Metro 0.12.1. In this application I don't show the titlebar, staying visible minimize, maximize and close commands. Below I show the code:
<controls:MetroWindow xmlns:views="clr-namespace:View.Views"
xmlns:titleBar="clr-namespace:View.Views.TitleBar"
x:Class="View.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:controls="clr-namespace:MahApps.Metro.Controls;assembly=MahApps.Metro"
GlowBrush="{DynamicResource AccentColorBrush}"
ShowWindowCommandsOnTop="False"
ShowTitleBar="False"
Title="MainWindow" Height="400" Width="600"
AllowsTransparency="False">
<Grid>
...
</Grid>
The problem arises when I upgrade to the version 0.13.1 of MathApps.Metro, where these commands are not displayed, forcing me to re-establish the titlebar to display the commands again ShowTitleBar="True" and this is what I do not want: display the titlebar.
I was looking at the release notes of MathApps.Metro 0.13.1 and reports that changes were made to the section of the titlebar​​, but no further details are given.
My questions are: Is there a simple way to display the minimize, maximize and close commands without showing the title bar? What is the best way to do this?
thanks
you can put the window buttons directly in your main window like this
<Grid>
<!-- the window button commands -->
<Controls:WindowButtonCommands Panel.ZIndex="1"
HorizontalAlignment="Right"
VerticalAlignment="Top"
Height="{Binding TitlebarHeight, Mode=OneWay, RelativeSource={RelativeSource FindAncestor, AncestorType={x:Type Controls:MetroWindow}}}" />
...
</Grid>
hope that helps

Actually not very simple, but possible. Basically you need to create your own Style template and override the ContentPresenter for your window to do so.
You may take a look at this question.
Besides that, this post will guide you through the process of designing your own titlebar.
I have added Awesomium webcontrol in my WPF Page (Frame Navigation)
But its not loading any webcontent, but if i add the webcontrol in WPF Window, its working fine.
Please suggest me how to load a Awesomium webcontrol within WPF Page control
Below is the code which i am using in my application
Thanks in advance.
<Page x:Class="Project15A.SocialMain"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:my="clr-namespace:Project15A"
xmlns:my1="clr-namespace:Project15A.Controls"
xmlns:my2="http://schemas.awesomium.com/winfx"
MinHeight="300" MinWidth="500" Title="Project15A"
Loaded="Window1_Loaded">
<Grid Background="White">
<my2:WebControl HorizontalAlignment="Left" Margin="154,65,0,0"
Name="webControl1" VerticalAlignment="Top"
Source="http://www.google.com" />
</Grid>
</Page>
So I figured this one out. It is not a bug in Awesomium. (Though I think it should be on a quick start page.)
Awesomium supports two view modes. Offscreen and Windowed.
Offscreen is something that very manual. All input goes through you. (Why the default events don't still fire is kind of odd). I think this is the mode you will end up using if you want to interact with your HTML.
But if you want a normal imbedded browser window then you need to turn on the Window view mode.
Here is an example:
<Window
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:awe="http://schemas.awesomium.com/winfx"
x:Class="WpfAndSpa.MainWindow">
<Grid>
<awe:WebControl x:Name="WebControl"
ViewType="Window" <--------------+
Source="http://google.com"/> |
</Grid> |
</Window> |
|
This is the key part -----------------------------------------+
I have been struggling with this question for some time now. It seems relatively simple, but I am unsure of how to solve it. Would love your aid on this.
I have a page that's bound to viewmodel, that has some string properties that represent file paths.
I've built a user control that has a textbox and a button. The control's purpose: show a dialog when you click on the button(file dialog), and update the textbox according to the result.
Here is the xaml:
<UserControl x:Class="MyProject.Controls.FilePickerLauncherControl"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
mc:Ignorable="d"
x:Name="me"
d:DesignHeight="300" d:DesignWidth="300">
<DockPanel>
<Button Content="..." DockPanel.Dock="Right" Command="{Binding OpenFileDialogCommand,ElementName=me}"></Button>
<TextBox Text="{Binding Path=PathChosen,ElementName=me}" DockPanel.Dock="Right" VerticalAlignment="Center" Height="30"></TextBox>
</DockPanel>
This is my the command in page's view model(the action):
private void OpenFileExplorer()
{
SimpleIoc.Default.GetInstance<IInputOutputService>().OpenFileDialog(modelsDirectory);
}
Now what I want to do, for every instance of my control, to take the result of the dialog and put it in the textbox that's in the control. I've been thinking of:
maybe a command parameter that would be sent to this OpenFileExplorer, telling which property should be updated somehow, but I am not sure how.
Write this command multiple times for each property. I don't think this is correct.
Create a new viewmodel for my control with this command and make instances of it in my current view model.
What would you guys say the best way to do this? it is relatively simple, although it got me kind of confused.
