CF - 如何在弹出ContextMenu时获取鼠标位置？

发布于 2024-09-02 13:34:13 字数 739 浏览 1 评论 0原文

我有一个无法解决的问题。

在我看来（显示地图）我创建了一个 contextMenu。当调用上下文菜单时，我需要获取用户在地图上单击的位置。

这是我的问题：

在视图中，我已经有 onMouseDown 事件，它可以获取用户单击的坐标。

private void MapView_MouseDown(object sender, MouseEventArgs e)
    {
        this.lastMouseDownX = e.X;
        this.lastMouseDownY = e.Y;
    }

当调用 contextMenu 时，我需要相同的数据，但问题是 contextMenu 仅具有不保留我需要的数据的 EventArgs。此外...当用户按住鼠标一秒钟时，将调用 contextMenu，并且当调用它时，代码不会进入 onMouseDown 事件！它只是进入我的上下文菜单上的弹出事件......

我尝试将其放入我的弹出事件中，但坐标不正确。 Y 坐标与图表相差甚远。

private void servicesContextMenu_Popup(object sender, EventArgs e)
{
    this.lastMouseDownX = Control.MousePosition.X;
    this.lastMouseDownX = Control.MousePosition.Y;
}

帮助？

原文

I have a problem i cannot solve.

In my view (that shows a map) i created a contextMenu.
When context menu is invoked i need to get the position where the user has clicked on the map.

Here is my problem:

In the view i already have onMouseDown event that gets me the coordinates where the user clicked.

private void MapView_MouseDown(object sender, MouseEventArgs e)
    {
        this.lastMouseDownX = e.X;
        this.lastMouseDownY = e.Y;
    }

When the contextMenu is invoked i need the same data, but the problem is that contextMenu only has EventArgs that dont keep the data i need. Furthermore ... contextMenu is invoked when user presses and holds mouse for a second and when its invoked the code does not enter onMouseDown event ! It just goes into popup event on my context menu....

I tried putting this in my popup event, but the coordinates are not ok. Y coordinate is way off the chart.

private void servicesContextMenu_Popup(object sender, EventArgs e)
{
    this.lastMouseDownX = Control.MousePosition.X;
    this.lastMouseDownX = Control.MousePosition.Y;
}
