有没有一个WPF“WrapGrid”控制可用还是创建一个简单的方法？ [英] Is there a WPF "WrapGrid" control available or an easy way to create one?

问题描述

基本上我想要一个wrapPanel，但我希望项目能够对齐到一个网格，而不是被按到左边，这样我就可以获得一个很好的统一外观网格，它会自动消耗可用空间。

WrapPanel处理调整大小的部分。
WPF.Contrib.AutoGrid处理一个很好的自动网格。

任何人都有一个控制它的结合？

我的使用案例是我有一系列有些不规则形状的控件。我希望它们出现在漂亮的列中，这样在放置控件时，换行面板应该对齐下一个tabstop。 解决方案

以下是一些基于其他一些接近控件的代码。它在布局方面做得不错，尽管它存在一个问题，那就是盛大的子控件没有填满所有可用的空间。

  protected override Size ArrangeOverride（Size finalSize）
 {
 double rowY = 0; 
 int col = 0; 
 double currentRowHeight = 0; 
 
 
 foreach（UIElement child in Children）
 {
 var initialSize = child.DesiredSize; 
 int colspan =（int）Math.Ceiling（initialSize.Width / ColumnSize）; 
 Console.WriteLine（colspan）; 
 double width = colspan * ColumnSize;如果（col> 0&&（col * ColumnSize）+ width> constrainedSize.Width）
 
 
 
 
 $ b {
 rowY + = currentRowHeight; 
 col = 0; 
 currentRowHeight = 0; 
} 
 
 
 var childRect = new Rect（col * ColumnSize，rowY，width，initialSize.Height）; 
 child.Arrange（childRect）; 
 currentRowHeight = Math.Max（currentRowHeight，initialSize.Height）; 
 col + = colspan; 
} 
 
 return finalSize; 
} 
 
尺寸constrainedSize; 
 
保护覆盖尺寸MeasureOverride（尺寸约束）
 {
 constrainedSize =约束; 
返回base.MeasureOverride（约束）; 
} 
  

Essentially I want a wrapPanel, but I would like items to snap to a grid rather than be pressed up to the left, so I can get a nice uniform looking grid, that automatically consumes available space.

WrapPanel handles the resize part. WPF.Contrib.AutoGrid handles a nice automatic grid.

Anyone got a control that combines them?

My use case is I have a series of somewhat irregularly shaped controls. I would like them to appear in nice columns so the wrap panel should snap to the next "tabstop" when placing a control

解决方案

Here is some code that I whipped up based on some of the other controls that are close. It does a decent job of doing the layout, although it has an issue where grand-child controls do not fill up all their available space.

  protected override Size ArrangeOverride(Size finalSize)
    {
        double rowY = 0;
        int col = 0;
        double currentRowHeight = 0;


        foreach (UIElement child in Children)
        {
            var initialSize = child.DesiredSize;
            int colspan  = (int) Math.Ceiling(initialSize.Width/ ColumnSize);
            Console.WriteLine(colspan);
             double width = colspan * ColumnSize;



            if (col > 0 && (col * ColumnSize) + width > constrainedSize.Width)
            {
                rowY += currentRowHeight;
                col = 0;
                currentRowHeight = 0;
            }


            var childRect = new Rect(col * ColumnSize, rowY, width, initialSize.Height);
            child.Arrange(childRect);
            currentRowHeight = Math.Max(currentRowHeight, initialSize.Height);
            col+=colspan;
        }

        return finalSize;
    }

    Size constrainedSize;

    protected override Size MeasureOverride(Size constraint)
    {
        constrainedSize = constraint;
        return base.MeasureOverride(constraint);
    }
