WPF 获取 Stackpanel 子邻居

Question

我有一个堆栈面板，我根据在别处定义的二维数组动态添加了按钮。所以本质上它构建了一个按钮网格，但添加为堆栈面板的子项。我需要做的是根据列号和行号指定一个子按钮。这是堆栈面板。

<StackPanel Name="myArea"  HorizontalAlignment="Center" VerticalAlignment="Center"/>

这里是一些有问题的代码。

Grid values = new Grid();
values.Width = 320;
values.Height = 240;
values.HorizontalAlignment = HorizontalAlignment.Center;
values.VerticalAlignment = VerticalAlignment.Center;

int x = valueBoard.GetLength(0);
int y = valueBoard.GetLength(1);

for (int i = 0; i < x; i++)
{
    ColumnDefinition col = new ColumnDefinition();
    values.ColumnDefinitions.Add(col);
}
for (int j = 0; j < y; j++)
{
    RowDefinition row = new RowDefinition();
    values.RowDefinitions.Add(row);
}
for (int i = 0; i < x; i++) for (int j = 0; j < y; j++)
{
    Button button = new Button();
    button.Content = "";
    button.Click += ButtonClick;  
    button.MouseRightButtonUp += RightClick;
    Grid.SetColumn(button, i);
    Grid.SetRow(button, j);
    values.Children.Add(button);
}
myArea.Children.Add(values);

所以现在，在单击一个按钮时，我想隐藏网格中所有相邻的按钮。这是我的点击事件：

private void ButtonClick(object sender, RoutedEventArgs e)
{
    int col = Grid.GetColumn((Button)sender);
    int row = Grid.GetRow((Button)sender);
    Button source = e.Source as Button;
    source.Visibility = Visibility.Hidden;
}

我如何在 ButtonClick 中隐藏具有 col 和 row 值的邻居按钮？是否有某种 getter 或 setter 我可以将这些值输入并编辑邻居的 Visibility 属性?

Answer 1

尝试以下操作：

private void ButtonClick(object sender, RoutedEventArgs e)
{
    int col = Grid.GetColumn((Button)sender);
    int row = Grid.GetRow((Button)sender);
    Button source = e.Source as Button;
    source.Visibility = Visibility.Hidden;
    Grid pGrid = source.Parent as Grid;
    if (pGrid == null) throw new Exception("Can't find parent grid.");

    for (int i = 0; i < pGrid.Children.Count; i++) {
        Button childButton = pGrid.Children[i] as Button;
        if(childButton == null) continue;

        int childCol = Grid.GetColumn(childButton);
        int childRow= Grid.GetRow(childButton);

        if(Math.Abs(childCol - col) < 2 && Math.Abs(childRow - row) < 2) childButton.Visibility = Visibility.Hidden;
    }
}

这将遍历您的 children，如果它是 Button 的类型，它将检查 row 和 column 是否在您的 [=14= 旁边] 并将隐藏它。
