C# 围绕矩形放置和粘贴控件
我正在开发一个小的剪贴工具,它可以工作,但我就是不知道如何在选定的剪贴区域(矩形)周围放置两个toolstrip控件。我在鼠标向上事件中刷新toolstrip位置,它像这样处理两个toolstrip的移动C# 围绕矩形放置和粘贴控件,c#,winforms,graphics,C#,Winforms,Graphics,我正在开发一个小的剪贴工具,它可以工作,但我就是不知道如何在选定的剪贴区域(矩形)周围放置两个toolstrip控件。我在鼠标向上事件中刷新toolstrip位置,它像这样处理两个toolstrip的移动 //The two toolstrips that I have //rcSelect is the selected rectangle toolStrip1.Visible = true; toolStrip2.Visible = true; //Tool Strip One int

我不知道哪个ToolStrip是垂直的还是水平的,但您可以这样尝试:
protected override void OnMouseDown(MouseEventArgs e) {
base.OnMouseDown(e);
rcSelect = new Rectangle(e.Location, Size.Empty);
}
protected override void OnMouseUp(MouseEventArgs e) {
base.OnMouseUp(e);
int rcLeft = Math.Min(e.X, rcSelect.X);
int rcTop = Math.Min(e.Y, rcSelect.Y);
int rcWidth = Math.Max(e.X, rcSelect.Left) - Math.Min(e.X, rcSelect.Left);
int rcHeight = Math.Max(e.Y, rcSelect.Top) - Math.Min(e.Y, rcSelect.Top);
rcSelect = new Rectangle(new Point(rcLeft, rcTop), new Size(rcWidth, rcHeight));
toolStrip1.Location = new Point(
Math.Max(0,
Math.Min(this.ClientSize.Width - toolStrip1.Width,
rcSelect.Right - toolStrip1.Width)
),
rcSelect.Bottom > this.ClientSize.Height ?
rcSelect.Top - toolStrip1.Height :
rcSelect.Bottom
);
toolStrip2.Location = new Point(
rcSelect.Right > this.ClientSize.Width ?
rcSelect.Left - toolStrip2.Width :
rcSelect.Right,
Math.Max(0,
Math.Min(this.ClientSize.Height - toolStrip2.Height,
rcSelect.Bottom - toolStrip2.Height)
)
);
}
工具条的位置是基于矩形对象的大小还是坐标?(
rcSelect
)。这个错误最有可能与坐标和大小的混乱有关,这些坐标和大小被用作分隔符,用于确定对象在显示器上的移动方式。
我有两项建议:
rcSelect
就可以重新实例化。这种方法的缺点是,工具条不再“跟随”矩形,而是在用户做出选择后重新绘制。如果不重新实例化,我建议在用户鼠标释放时重新绘制toolstripsrcSelect
。为了避免脱离屏幕,您可以修改将哪个角用作锚点。这会将移动选项更改为四个设置位置X
坐标,但无法纠正它的Y
。但是,您的水平toolstrip相互呈现相同的错误,但相反
请查看您的等式,并告知我们您是否解决了任何问题:)第一幅图像和第二幅图像中rcSelect的位置和大小是多少?对不起,不确定位置,但矩形上方提到了大小。不确定?看来这非常重要。显示确定rcSelect值的代码。请检查调试2否,我们需要查看设置rcSelect位置和维度的代码。谢谢,我切换了工具名称,如下所示。但我的代码也会根据snip所在的位置更改striptool的位置。例如,当snip位于屏幕右侧和右下角时,@m.qayyum会更新代码以适应屏幕外的问题。主要思想就在这里。

base.OnMouseDown(e);
rcSelect = new Rectangle(e.Location, Size.Empty);
