[英]Detect click on resize window UWP
I would like to launch a message dialog at the click of the resize button.. 我想单击调整大小按钮启动一个消息对话框。
I inserted the message dialog in any click, but how can I launch it in the resize window? 我单击鼠标即可插入消息对话框,但是如何在调整大小窗口中启动它呢?
The code: 编码:
public sealed partial class MainPage : Page
{
public MainPage()
{
this.InitializeComponent();
}
private async void Button_Click(object sender, RoutedEventArgs e)
{
var messageDialog = new MessageDialog("This is a Message dialog");
await messageDialog.ShowAsync();
}
}
I approached a possible solution but, I just need the resize button click, is it possible? 我找到了一个可能的解决方案,但是,我只需要单击调整大小按钮,可以吗?
The code: 编码:
Window.Current.CoreWindow.SizeChanged += (ss, ee) =>
{
var appView = Windows.UI.ViewManagement.ApplicationView.GetForCurrentView();
if (appView.IsFullScreen)
{
//show message
}
ee.Handled = true;
};
Thanks in advance! 提前致谢!
You can subscribe to Page Size changed event for this 您可以为此订阅“页面大小已更改”事件
XAML XAML
<Page
x:Class="App.MainPage"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="using:SO15"
xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
mc:Ignorable="d" SizeChanged="Page_SizeChanged"> <!-- SizeChanged event -->
C# C#
private void Page_SizeChanged(object sender, SizeChangedEventArgs e)
{
Window.Current.CoreWindow.SizeChanged += async (ss, ee) =>
{
var appView = ApplicationView.GetForCurrentView();
if (appView.IsFullScreen)
{
var messageDialog = new MessageDialog("Window is Maximized");
await messageDialog.ShowAsync();
}
ee.Handled = true;
};
Window.Current.CoreWindow.SizeChanged += async (ss, ee) =>
{
var appView = ApplicationView.GetForCurrentView();
if (!appView.IsFullScreen)
{
var messageDialog = new MessageDialog("Window is not Maximized");
await messageDialog.ShowAsync();
}
ee.Handled = true;
};
}
Alternately handle it in c# Recommended 交替使用c#推荐处理
using this event 使用这个事件
Window.Current.CoreWindow.SizeChanged += CoreWindow_SizeChanged;
bool msgboxshown = false; //add this condition in above solution also if msg dialog shown multiple times at the time of mazimizing window
private async void CoreWindow_SizeChanged(Windows.UI.Core.CoreWindow sender, Windows.UI.Core.WindowSizeChangedEventArgs args)
{
var appView = ApplicationView.GetForCurrentView();
if (!appView.IsFullScreen && !msgboxshown)
{
var messageDialog = new MessageDialog("Window is not maximized");
msgboxshown = true;
await messageDialog.ShowAsync();
msgboxshown = false;
}
if (appView.IsFullScreen && !msgboxshown)
{
var messageDialog = new MessageDialog("Windows is maximized");
msgboxshown = true;
await messageDialog.ShowAsync();
msgboxshown = false;
}
args.Handled = true;
}
/* You can remove msgboxshown condition , it is because message dialog will show continuously multiple times */
