问题描述

触发器上的延迟

我在WPF中使用了几个按钮用于显示来自各种文件夹的图像。所有按钮的单击模式为 Hover 。对于某些按钮，在悬停之后，它被路由到一个函数 OnButtonClick 。我想要做的是，只有当鼠标超过 X 秒的按钮后，函数 OnButtonClick 。

I am using a few buttons in WPF for displaying images from various folders. The Click mode for all the buttons is Hover. For some button, after hovering, it is routed to a function OnButtonClick. What I want to do is, ONLY after the mouse is over the button for X seconds, the processing inside the function OnButtonClick should be done.

XAML代码：

XAML Code:

    <Button Name="Dresses" Content="Dresses" Click="OnButtonClickDresses" Grid.Row="2" Height="34" Width="85" VerticalAlignment="Center" Grid.Column="5"  FontFamily="Tahoma" FontSize="14" FontWeight="Bold" HorizontalAlignment="Center" Cursor="Hand" ClickMode="Hover">
        <Button.Background>
            <LinearGradientBrush>
                <GradientStop Color="Yellow" Offset="0" />
                <GradientStop Color="Green" Offset="1" />
            </LinearGradientBrush>
        </Button.Background>
    </Button>

C＃代码：

    private void OnButtonClickDresses(object sender, RoutedEventArgs e)
    {
            //Code for delay

            //Code which should run only if mouse on button after 5 seconds

    }

推荐答案

在MouseOver事件上使用触发器。一旦鼠标在你的控制，启动一个计时器。如果它在鼠标仍在控件上方的时候消失，请模拟一次点击。

Use a trigger on the MouseOver event. Once the mouse is over your control, start a timer. If it elapses while the mouse is still over the control, simulate a click.
