我正在开发一个小型剪切工具，它可以工作，但我无法理解如何在选定的剪切区域(矩形)周围放置两个工具条控件。我在鼠标弹起事件上刷新工具条位置，它会像这样处理两个工具条的移动。
//The two toolstrips that I have
//rcSelect is the selected rectangle
toolStrip1.Visible = true;
toolStrip2.Visible = true;
//Tool Strip One
int toolstripY = (rcSelect.Y + rcSelect.Height) - toolStrip1.Height;
int toolstripX = rcSelect.Width + rcSelect.X + 5;
if (toolstripX + toolStrip1.Width >= this.Width)
{
toolstripX = rcSelect.X - toolStrip1.Width - 5;
}
if (rcSelect.Width + toolStrip1.Width >= this.Width)
{
toolstripX = rcSelect.Width - toolStrip1.Width;
}
if (toolstripY + toolStrip1.Height >= this.Height)
{
toolstripY = rcSelect.Y;
}
if (rcSelect.Height + toolStrip1.Height >= this.Height)
{
toolstripY = rcSelect.Height;
}
if (toolStrip1.Location.Y + toolStrip1.Height >= this.Height)
{
toolstripY = rcSelect.Y - toolStrip1.Height - 5;
}
//Tool Strip Two
int toolstrip2Y = rcSelect.Y + rcSelect.Height + 5;
int toolstrip2X = rcSelect.X + (rcSelect.Width - toolStrip2.Width);
if (toolstrip2Y + toolStrip2.Height >= this.Height)
{
toolstrip2Y = rcSelect.Y - toolStrip2.Height - 5;
}
if (rcSelect.Height + toolStrip2.Height >= this.Height)
{
toolstrip2Y = rcSelect.Height - toolStrip2.Height;
}
if (toolstrip2X + toolStrip2.Width >= this.Width)
{
toolstrip2X = rcSelect.X;
}
if (rcSelect.Width + toolStrip2.Width >= this.Width)
{
toolstrip2X = rcSelect.Width;
}
if (toolStrip2.Location.X + toolStrip2.Width >= this.Width)
{
toolstrip2X = rcSelect.X - toolStrip2.Width - 5;
}
//Try to Insure visbility yet again
if (toolStrip1.Location.Y + toolStrip1.Height >= this.Height)
{
int offsetY = (toolStrip1.Location.Y + toolStrip1.Height) - this.Height;
toolstripY = toolStrip1.Location.Y - offsetY;
}
if (toolStrip2.Location.X + toolStrip2.Width >= this.Width)
{
int offsetX = (toolStrip2.Location.X + toolStrip2.Width) - this.Width;
toolstrip2X = toolStrip2.Location.X - offsetX;
}
if (toolstrip2X < 0)
{
toolstrip2X = 0;
}
if (toolstrip2Y < 0)
{
toolstrip2Y = 0;
}
if (toolstripX < 0)
{
toolstripX = 0;
}
if (toolstripY < 0)
{
toolstripY = 0;
}
toolStrip1.Location = new Point(toolstripX, toolstripY);
toolStrip2.Location = new Point(toolstrip2X, toolstrip2Y);
这是开始时的样子。
这就是我调整大小并移动该矩形时的样子

垂直一是toolstrip1，水平是toolstrip2。

最佳答案
我不知道哪个ToolStrip是垂直的还是水平的，不过你可以这样试试:
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)
)
);
}
